Understanding Pristiq and Its Role in Treating Depression

Pristiq, with its active ingredient desvenlafaxine, is a prescription medication used to treat major depressive disorder in adults. As an antidepressant, it plays a crucial role in managing depression symptoms. However, like many medications, it comes with potential side effects that patients should be aware of.

Typically administered as a long-term treatment, Pristiq is available in tablet form for oral consumption. Its effectiveness in treating depression has made it a common choice among healthcare providers, but understanding its side effects is crucial for patients to make informed decisions about their treatment.

Common Side Effects of Pristiq: What to Expect

While Pristiq can be effective in treating depression, it’s important to be aware of its potential side effects. Common side effects reported by patients include:

• Dizziness
• Trouble sleeping
• Increased sweating
• Loss of appetite
• Nausea
• Vomiting
• Drowsiness
• Anxiety
• Dry mouth
• Sexual side effects
• Headache
• Constipation

Can these side effects be managed? In most cases, these side effects are temporary and can be managed effectively. However, if they persist or become bothersome, it’s essential to consult with a healthcare provider. They may be able to suggest strategies to alleviate these symptoms or adjust the treatment plan if necessary.

Nausea and Pristiq: A Closer Look

Among the various side effects, nausea is one of the most commonly reported issues associated with Pristiq. For many patients, this can be a significant concern that impacts their daily life and potentially their adherence to the medication.

Why does Pristiq cause nausea? The exact mechanism isn’t fully understood, but it’s believed to be related to how the medication affects serotonin levels in the body. Serotonin plays a role in regulating digestion, and changes in its levels can lead to gastrointestinal disturbances, including nausea.

Strategies for Managing Pristiq-Induced Nausea

If you’re experiencing nausea while taking Pristiq, consider these strategies:

1. Take the medication with food
2. Stay hydrated
3. Eat smaller, more frequent meals
4. Avoid spicy or fatty foods
5. Try ginger tea or peppermint
6. Practice relaxation techniques

Is nausea from Pristiq permanent? For most people, nausea tends to improve over time as the body adjusts to the medication. However, if it persists or becomes severe, it’s crucial to consult with your healthcare provider. They may be able to adjust your dosage or suggest additional strategies to manage this side effect.

Serious Side Effects of Pristiq: When to Seek Medical Attention

While most side effects of Pristiq are mild, there are some serious side effects that require immediate medical attention. These include:

• Increased blood pressure
• Mania or hypomania
• Serotonin syndrome
• Increased risk of bleeding
• Angle-closure glaucoma
• Seizures
• Low sodium levels in the blood
• Suicidal thoughts or actions

How can patients recognize these serious side effects? Symptoms may include severe headache, rapid heartbeat, confusion, unusual bleeding or bruising, eye pain or vision changes, and sudden changes in mood or behavior. If you experience any of these symptoms, it’s crucial to seek medical help immediately.

Pristiq and Weight Changes: Understanding the Connection

Weight changes are a concern for many patients taking antidepressants. While weight gain was not reported as a side effect in clinical studies of Pristiq, some patients have reported experiencing weight gain after the medication was released to the market.

Is weight gain inevitable with Pristiq? Not necessarily. It’s important to note that weight changes, including weight gain, can also be a symptom of depression itself. If you notice significant weight changes while taking Pristiq, it’s best to discuss this with your healthcare provider.

Managing Weight While on Pristiq

If you’re concerned about potential weight gain while taking Pristiq, consider these strategies:

• Maintain a balanced diet
• Engage in regular physical activity
• Monitor your weight regularly
• Discuss any concerns with your healthcare provider

Can lifestyle changes help manage weight while on Pristiq? Absolutely. A healthy diet and regular exercise can not only help manage weight but may also contribute to improved mood and overall well-being.

Sleep Disturbances and Pristiq: Finding Balance

Sleep disturbances, including trouble sleeping and drowsiness, are commonly reported side effects of Pristiq. These can significantly impact a patient’s quality of life and potentially their response to treatment.

How does Pristiq affect sleep patterns? Pristiq can influence the body’s natural sleep-wake cycle. Some patients may experience insomnia, while others might feel excessively drowsy during the day.

Tips for Improving Sleep While Taking Pristiq

If you’re experiencing sleep issues while on Pristiq, consider these strategies:

1. Establish a consistent sleep schedule
2. Create a relaxing bedtime routine
3. Avoid caffeine and electronic devices before bed
4. Exercise regularly, but not too close to bedtime
5. Consider taking Pristiq in the morning if nighttime dosing affects sleep

Can the timing of Pristiq dosage affect sleep? Yes, the timing of when you take Pristiq can impact your sleep patterns. If you’re experiencing sleep disturbances, discuss with your healthcare provider about potentially adjusting the timing of your dose.

Sexual Side Effects of Pristiq: Breaking the Taboo

Sexual side effects are a common but often underreported issue with many antidepressants, including Pristiq. These can include decreased libido, difficulty achieving orgasm, and erectile dysfunction in men.

Why do antidepressants like Pristiq cause sexual side effects? The exact mechanism isn’t fully understood, but it’s believed to be related to how these medications affect neurotransmitters in the brain, particularly serotonin.

Addressing Sexual Side Effects

If you’re experiencing sexual side effects while taking Pristiq, consider these approaches:

• Open communication with your partner
• Discuss the issue with your healthcare provider
• Consider adjusting the timing of medication
• Explore non-drug strategies to enhance sexual function

Are sexual side effects reversible? In many cases, sexual side effects improve over time as the body adjusts to the medication. However, if they persist, your healthcare provider may consider adjusting your dosage or exploring alternative treatments.

Discontinuation Syndrome: The Importance of Gradual Tapering

Discontinuation syndrome, often referred to as withdrawal symptoms, can occur if Pristiq is stopped abruptly. This can lead to a range of uncomfortable symptoms and potentially serious side effects.

What are the symptoms of Pristiq discontinuation syndrome? Common symptoms include nausea, sweating, dizziness, headache, irritability, and the sensation of “brain zaps”. More severe symptoms can include seizures, suicidal thoughts, and severe aggression.

Safely Discontinuing Pristiq

If you need to stop taking Pristiq, it’s crucial to do so under medical supervision. Your healthcare provider will likely recommend a gradual tapering schedule, which may include:

1. Slowly reducing the dosage over time
2. Monitoring for withdrawal symptoms
3. Providing supportive care as needed
4. Considering alternative treatments if necessary

How long does it take to safely discontinue Pristiq? The tapering process can take several months, depending on your current dosage and individual factors. It’s important to follow your healthcare provider’s instructions closely during this process.

Pristiq and Pregnancy: Weighing the Risks and Benefits

For pregnant women or those planning to become pregnant, the use of Pristiq requires careful consideration. While untreated depression during pregnancy can pose risks, there are also potential risks associated with taking antidepressants during pregnancy.

What are the potential risks of taking Pristiq during pregnancy? Some studies have suggested a small increased risk of certain birth defects with the use of antidepressants during pregnancy. However, the overall risk is still considered low.

Considerations for Pristiq Use During Pregnancy

If you’re pregnant or planning to become pregnant while taking Pristiq, consider these points:

• Discuss the risks and benefits with your healthcare provider
• Consider alternative treatments if appropriate
• Monitor closely for any changes in mood or symptoms
• Be aware of potential effects on the newborn, such as withdrawal symptoms

Can Pristiq be safely used while breastfeeding? Pristiq can pass into breast milk, so it’s important to discuss this with your healthcare provider if you plan to breastfeed. They can help you weigh the potential benefits of breastfeeding against any risks to the baby.

Interactions with Other Medications: What Patients Should Know

Pristiq can interact with various other medications, potentially altering its effectiveness or increasing the risk of side effects. It’s crucial for patients to inform their healthcare providers about all medications they’re taking, including over-the-counter drugs and supplements.

Which medications can interact with Pristiq? Some notable interactions include:

• Other antidepressants, particularly MAOIs
• Blood thinners
• NSAIDs (like ibuprofen)
• Certain migraine medications
• Some herbal supplements, like St. John’s Wort

How can patients avoid dangerous drug interactions? Always inform your healthcare provider about all medications and supplements you’re taking. They can assess potential interactions and adjust your treatment plan if necessary.

The Role of Pharmacists in Medication Safety

Pharmacists play a crucial role in ensuring medication safety. They can:

1. Screen for potential drug interactions
2. Provide information about proper medication use
3. Offer advice on managing side effects
4. Answer questions about your medications

Should patients consult their pharmacist about Pristiq side effects? Absolutely. Pharmacists are excellent resources for information about medications, including potential side effects and how to manage them.

Long-Term Use of Pristiq: What to Expect

Pristiq is often prescribed as a long-term treatment for depression. Understanding what to expect with prolonged use can help patients make informed decisions about their treatment.

Does the effectiveness of Pristiq change over time? For many patients, Pristiq remains effective over long periods. However, some may experience a change in effectiveness or side effects over time.

Monitoring Long-Term Pristiq Use

For patients on long-term Pristiq treatment, regular monitoring is important. This may include:

• Regular check-ups with your healthcare provider
• Blood pressure monitoring
• Assessing ongoing effectiveness of the medication
• Discussing any new or changing side effects
• Considering dosage adjustments if necessary

How often should patients on long-term Pristiq treatment see their healthcare provider? This can vary depending on individual circumstances, but generally, patients should have regular check-ups, at least every few months, to assess their treatment progress and address any concerns.

Alternative Treatments: When Pristiq Isn’t the Right Fit

While Pristiq can be effective for many patients, it’s not the right choice for everyone. Understanding alternative treatment options is important for those who experience intolerable side effects or find Pristiq ineffective.

What are some alternatives to Pristiq for treating depression? Alternatives may include:

1. Other antidepressant medications
2. Psychotherapy or counseling
3. Combination therapy (medication plus therapy)
4. Alternative treatments like transcranial magnetic stimulation (TMS)
5. Lifestyle changes, including diet and exercise

How do patients know if they should consider alternative treatments? If you’re experiencing severe side effects, not seeing improvement in your symptoms, or have concerns about long-term use of Pristiq, it’s important to discuss these issues with your healthcare provider. They can help you explore alternative options that may be more suitable for your individual needs.

The Importance of Personalized Treatment Plans

Every patient’s experience with depression and its treatment is unique. A personalized approach to treatment can involve:

• Tailoring medication choice and dosage to individual needs
• Combining different treatment modalities
• Regular assessment and adjustment of the treatment plan
• Consideration of personal preferences and lifestyle factors

Can a combination of treatments be more effective than Pristiq alone? For some patients, a combination of treatments, such as medication plus psychotherapy, can be more effective than medication alone. Your healthcare provider can help determine the most appropriate treatment approach for your specific situation.

If you have symptoms of a severe allergic reaction, such as swelling or trouble breathing, call 911 or your local emergency number right away. These symptoms could be life threatening and require immediate medical care.

If your doctor confirms you’ve had a serious allergic reaction to Pristiq, they may have you switch to a different treatment.

Keeping track of side effects

During your Pristiq treatment, consider taking notes on any side effects you’re having. You can then share this information with your doctor. This is especially helpful when you first start taking new drugs or using a combination of treatments.

Your side effect notes can include things such as:

• what dose of the drug you were taking when you had the side effect
• how soon you had the side effect after starting that dose
• what your symptoms were
• how it affected your daily activities
• what other medications you were taking
• any other information you feel is important

Keeping notes and sharing them with your doctor will help them learn more about how Pristiq affects you. They can then use this information to adjust your treatment plan if needed.

Pristiq comes with several warnings.

Boxed warning: Risk of suicidal thoughts and actions

Pristiq has a boxed warning for the risk of suicidal thoughts and actions in children, adolescents, and adults ages 24 years and younger. A boxed warning is the most serious warning from the Food and Drug Administration (FDA).

To learn more, see the “Side effects explained” section above.

Other warnings

Pristiq may cause drug-condition interactions. This means that Pristiq may not be right for you if you have certain medical conditions. Other factors may also affect whether Pristiq is a good treatment option for you.

Talk with your doctor about your health history before starting Pristiq. The list below includes factors to consider.

High blood pressure. Pristiq can cause your blood pressure to increase.If you have high blood pressure, your doctor may prescribe medication to treat it before you start taking Pristiq. Then they’ll monitor your blood pressure to make sure it’s well-managed. If your blood pressure remains high, your doctor may adjust your dosage of Pristiq or recommend a different antidepressant.

Heart disease. If you have heart disease, Pristiq may make it worse. Pristiq can increase your blood pressure, which may worsen heart disease. If you have a history of heart disease or high blood pressure, tell your doctor before starting Pristiq treatment.

Stroke or ministroke. Pristiq can increase your blood pressure, so it may increase your risk of stroke if you’ve had one before. If you’ve had a stroke or if you’ve had any problems with high blood pressure, let your doctor know. This will help them determine whether it’s safe for you to take Pristiq.

Bleeding problems. Medications like Pristiq may increase your risk of bleeding. If you take medications that increase bleeding, your risk may be greater. Before you take Pristiq, make sure your doctor knows all of the medications you take.

Angle-closure glaucoma. Pristiq may cause dilation of the pupils in the eye. This can cause an episode of glaucoma in certain people. Because of this, doctors will likely not prescribe Pristiq to anyone with this kind of glaucoma. If you have a history of glaucoma or if you take any eye drops for glaucoma, tell your doctor. They’ll discuss with you treatment options that are safe for you to take.

Mania, hypomania, or bipolar disorder. Pristiq may not be the right medication for people who have had mania, hypomania, or bipolar disorder. It also may not be safe for people who have a family history of these mental health conditions. If you have bipolar disorder, Pristiq can increase your risk of a manic episode. Before you start Pristiq treatment, tell your doctor about any mental health conditions you or close family members have had.

Allergic reaction. If you’ve had an allergic reaction to Pristiq or any of its ingredients, your doctor will likely not prescribe Pristiq. Ask them what other medications are better options for you.

Seizures or epilepsy. Pristiq was not studied in people with a history of seizures or epilepsy. If you’ve ever had a seizure or have epilepsy, tell your doctor. They’ll let you know if Pristiq is safe for you to take.

Low sodium level. Pristiq can lower the blood level of sodium, which can become a serious problem. Older adults (ages 65 years and older) or people who take diuretics may have a higher risk of this side effect. If you are an older adult or take a diuretic, or have had problems with a low sodium level in the past, your doctor will let you know whether it’s safe to take Pristiq.

Liver problems. If you have liver problems, your body may have trouble getting rid of Pristiq. Before you start treatment, tell your doctor about any liver problems you have or have had. They may prescribe a lower dosage of Pristiq.

Kidney problems. If you have kidney problems, your body may have trouble getting rid of Pristiq. Before you start treatment, tell your doctor about any kidney problems you have or have had. They may recommend that you take a lower dosage of Pristiq.

High cholesterol or triglycerides. Pristiq may increase cholesterol or triglycerides in certain people. If you’ve had high cholesterol or triglycerides or take medication to treat these conditions, tell your doctor. They may recommend more frequent blood tests to check levels of these substances while you’re taking Pristiq.

Alcohol and Pristiq

You should not take Pristiq with alcohol. Alcohol may increase your risk of side effects and may make depression worse.

Before you start taking Pristiq, tell your doctor if you drink alcohol. They may suggest ways to stop drinking or recommend a different medication for you.

Pregnancy and breastfeeding while taking Pristiq

Before taking Pristiq, talk with your doctor if you are pregnant or plan to become pregnant. They can help you decide if Pristiq is the best choice for you during this time.

Certain antidepressants can increase the risk of preeclampsia or bleeding complications during pregnancy. Taking Pristiq in the third trimester of pregnancy may cause withdrawal symptoms in your newborn.

If you become pregnant during treatment with Pristiq, ask your doctor about registering with the National Pregnancy Registry for Antidepressants. This registry gathers data from people who’ve taken Pristiq while pregnant. This data can help determine the safety of taking antidepressants such as Pristiq during pregnancy.

Small amounts of Pristiq may pass into breast milk. But it’s not known if Pristiq is safe to take during breastfeeding. If you’re breastfeeding or planning to breastfeed, talk with your doctor about ways to safely feed your child during treatment with Pristiq.

Pristiq may help treat your depression symptoms. Some people have mild side effects from the drug, such as nausea and constipation. More serious side effects from Pristiq aren’t common.

If you have questions about Pristiq’s side effects, talk with your doctor or pharmacist. Here are a few questions to ask about treatment with Pristiq:

• Is my risk of sexual side effects higher when I first start treatment?
• Does my risk of nausea and vomiting depend on what dose I take?
• Does Pristiq have more side effects than other drugs that treat my condition?

Long-term side effects

Although Pristiq can cause some serious side effects, these were rarely reported in clinical studies. Most of them aren’t long term and should go away if treatment with Pristiq is stopped.

But in rare cases, Pristiq may cause long-term side effects. For example, interstitial lung disease (scarring in your lungs) may not go away, even if you stop taking Pristiq. And if you develop high blood pressure from Pristiq, you may need to take medication long term for this condition.

Pristiq may also cause long-term side effects in people who already have certain medical conditions. For more information, see the “Precautions for Pristiq” section below.

Pristiq may cause several side effects. Here are some frequently asked questions about the drug’s side effects and their answers.

Do Pristiq side effects go away?

If your doctor prescribes Pristiq for you, you may wonder how long Pristiq side effects last.

Most mild side effects caused by Pristiq usually go away on their own after a few days to weeks. Although the medication can also cause serious side effects, most of these can be treated and go away if you stop taking Pristiq.

But in rare cases, Pristiq may cause long-term side effects that don’t go away. For more information, see “Long-term side effects” in the “Serious side effects” section above.

Are weight gain and weight loss side effects of Pristiq?

A very small number of people reported weight gain from taking Pristiq in clinical studies. In addition, decreased appetite was a common side effect in people who took Pristiq. Having less of an appetite may cause you to lose weight.

Keep in mind that depression, which Pristiq is prescribed to treat, can also affect your appetite and your weight. It can be difficult to know whether weight changes are due to depression symptoms easing, medications (such as Pristiq), or a combination of factors.

If you’re concerned about your weight, talk with your doctor. They can advise you on how to maintain a moderate weight with your depression treatment plan.

Could stopping Pristiq treatment cause side effects of withdrawal?

Yes, stopping treatment with antidepressants, such as Pristiq, can cause side effects of withdrawal. This is also known as antidepressant discontinuation syndrome.

For more information about this syndrome and Pristiq, see the “Side effects specific” section below.

Do Pristiq’s side effects vary depending on the strength (25 mg, 50 mg, 100 mg)?

Yes, Pristiq’s side effects can vary depending on the strength. In general, side effects are more likely to happen with higher doses.

To see more information about how side effects varied depending on strength in clinical trials, you can refer to the Pristiq’s prescribing information.

Does Pristiq cause side effects when you first start treatment?

It’s possible for Pristiq to cause side effects when you first start treatment. Some of the more common ones when you begin taking the drug can include:

• nausea
• dizziness
• decreased appetite
• feeling anxious

For most people, these side effects are usually mild and ease within a few days to weeks.

Keep in mind that side effects can occur at any time while you take Pristiq. If your doctor increases your dose of the drug, side effects may become more bothersome.

If you have side effects that don’t go away or become severe during your Pristiq treatment, be sure to talk with your doctor.

Learn more about some of the side effects that Pristiq may cause.

Headache

It’s possible to have headache as a side effect from Pristiq. But this wasn’t commonly reported by people taking the medication in clinical studies.

Headache can also be a symptom of serious side effects of Pristiq. These side effects rarely occurred with the drug but can include:

• high blood pressure
• low blood sodium levels
• closed-angle glaucoma,* in certain people

* To learn more, see the “Precautions for Pristiq” section below.

What you can do

If you have a sudden, severe headache while taking Pristiq, talk with your doctor right away. This could be a symptom of the serious side effects mentioned above.

If you have a mild headache while during Pristiq treatment, talk with your doctor or pharmacist. Certain over-the-counter pain relievers may increase your risk of bleeding if you take them with Pristiq. This is why it’s important to not take any medication for headache unless you first speak with your doctor or pharmacist.

Sexual side effects

Pristiq can rarely cause sexual side effects. Such side effects can occur with antidepressant medications, including Pristiq.

Sexual side effects were more likely to happen in males* taking Pristiq in clinical trials and included:

• reduced sex drive
• erectile dysfunction
• delayed ejaculation or not being able to ejaculate

A small number of females* taking Pristiq in these studies reported reduced sex drive and not being able to have an orgasm.

The risk of sexual side effects increases with higher doses of Pristiq.

* Sex and gender exist on spectrums. Use of the terms “male” and “female” in this article refers to sex assigned at birth.

What you can do

If you have sexual side effects while taking Pristiq, talk with your doctor. These side effects may ease over time. But if they don’t go away, your doctor may recommend that you switch to a different antidepressant. They can recommend the best treatment plan for your depression.

Discontinuation syndrome

Stopping treatment with antidepressants, such as Pristiq, can cause side effects of withdrawal. This is also known as antidepressant discontinuation syndrome. It’s not known how often people taking Pristiq in clinical studies had withdrawal symptoms.

Withdrawal symptoms can be severe, especially if you suddenly stop taking a high dose of Pristiq. Withdrawal symptoms can include:

• aggressive or hostile behavior
• confusion
• diarrhea
• dizziness
• feeling agitated, anxious, or irritated
• feeling pins and needles or having electric shock sensations
• headache
• insomnia (trouble sleeping)
• changes in mood
• nausea
• seizures
• suicidal thoughts and actions*
• tinnitus (ringing or other noise in your ears)
• tremor

Keep in mind that missing a dose of Pristiq may also cause mild withdrawal symptoms. They can include dizziness, headache, changes in mood, and feeling anxious. These symptoms should ease shortly after you take a dose. To help make sure that you don’t miss a dose, try using a medication reminder.

* Pristiq has a boxed warning for this side effect. This is the most serious warning from the Food and Drug Administration (FDA). To learn more, see “Suicidal thoughts and actions” below.

What you can do

You should not stop taking Pristiq unless your doctor specifically advises you to.

If you’re interested in stopping Pristiq treatment, talk with your doctor. They can suggest a drug taper for you. A drug taper is when your doctor slowly decreases your dosage over time until it’s safe for you to stop taking the medication. Tapering drugs such as Pristiq can help avoid or minimize withdrawal symptoms. Keep in mind that if you’re taking a high dose of Pristiq, your drug taper may take several months.

High blood pressure

Treatment with Pristiq can cause hypertension (high blood pressure), but this wasn’t common in clinical studies.

High blood pressure doesn’t cause symptoms in most people.

If you have certain medical conditions, they may worsen if you take Pristiq and have high blood pressure as a side effect. These conditions include:

• high blood pressure
• heart disease
• history of stroke or ministroke

To learn more, see the “Precautions for Pristiq” section below.

What you can do

Before you start taking Pristiq, your doctor will typically check your blood pressure. They’ll also monitor your blood pressure during your treatment.

If you have high blood pressure, it will need to be treated before you start taking Pristiq.

If you develop high blood pressure, your doctor will typically decrease your Pristiq dose. But if your blood pressure remains high, they may recommend a different treatment for your depression.

Allergic reaction

As with most drugs, Pristiq can cause an allergic reaction in some people. This side effect was rare in clinical studies of the drug.

Symptoms of allergic reaction can be mild or serious and can include:

• rash
• itching
• flushing (temporary warmth, redness, or deepening of skin color)
• swelling under your skin, typically in your lips, eyelids, feet, or hands
• swelling of your mouth, tongue, or throat, which can make it hard to breathe

What you can do

For mild symptoms of an allergic reaction, call your doctor right away. They may recommend ways to ease your symptoms and determine whether you should keep taking Pristiq. But if your symptoms are serious and you think you’re having a medical emergency, immediately call 911 or your local emergency number.

Suicidal thoughts and actions

Pristiq has a boxed warning about suicidal thoughts and actions. This is the most serious warning from the FDA. A boxed warning alerts doctors and patients about drug effects that may be dangerous.

Antidepressant drugs, including Pristiq, can increase the risk of suicidal thoughts and actions in children and young adults younger than age 25 years. This risk is highest during your first few months of taking an antidepressant and any time your dose is changed.

Pristiq is not approved for use in people younger than age 18.

It’s important to note that depression and other mental health conditions are often linked to suicidal thoughts or actions.

What you can do

While taking Pristiq, call your doctor right away if you:

• have aggressive or hostile behavior
• feel that your depression is getting worse
• have sudden changes in your behavior, feelings, mood, or thoughts
• have thoughts about harming yourself or dying
• have new or worsening anxiety
• have panic attacks
• try to harm yourself or attempt to take your own life

During your Pristiq treatment, it’s important to keep all follow-up appointments with your doctor. You can also talk with your doctor in between visits if you have concerns about any symptoms.

Suicide prevention

If you know someone at immediate risk of self-harm, suicide, or hurting another person:

• Ask the tough question: “Are you considering suicide?”
• Listen to the person without judgment.
• Call 911 or the local emergency number, or text TALK to 741741 to communicate with a trained crisis counselor.
• Stay with the person until professional help arrives.
• Try to remove any weapons, medications, or other potentially harmful objects.

If you or someone you know is having thoughts of suicide, a prevention hotline can help. The 988 Suicide and Crisis Lifeline is available 24 hours a day at 988. During a crisis, people who are hard of hearing can use their preferred relay service or dial 711 then 988.

Boxed warning: Suicidal thoughts and actions

Pristiq has a boxed warning for suicidal thoughts and actions. This is a serious warning from the Food and Drug Administration (FDA). For details, see the “Side effect specifics” section above.

Other precautions

Be sure to talk with your doctor about your health history before you take Pristiq. This drug may not be the right treatment for you if you have certain medical conditions or other factors that affect your health. The conditions and factors to consider include:

Bipolar disorder, mania, or hypomania. Pristiq may not be safe for you to take if you or a close relative has ever had bipolar disorder, mania, or hypomania. Antidepressants such as Pristiq may worsen these problems or increase your risk of a manic episode. In addition, Pristiq is not approved to treat bipolar depression. Be sure to talk with your doctor about your mental health before you start taking Pristiq.

High bleeding risk. Treatment with Pristiq can increase your risk of bleeding. Your risk may be higher than usual if you already have a bleeding problem, such as hemophilia, or take certain drugs. These medications include blood thinners and nonsteroidal anti-inflammatory drugs (NSAIDs). Your doctor can determine if Pristiq is safe for you to take with your condition and current treatments.

Heart problems. Taking Pristiq can cause increases in your blood pressure. This could worsen any existing heart problem, including heart disease, you already have. Your doctor can advise you on whether Pristiq is safe for you to take if you have a heart problem.

High blood pressure. Taking Pristiq can cause increases in your blood pressure. People who already have high blood pressure may need to be monitored more closely if they take Pristiq. Your blood pressure needs to be treated before you can consider treatment with Pristiq. Your doctor can help determine if Pristiq is safe for you to take with your high blood pressure.

High cholesterol or triglycerides. Pristiq may raise cholesterol or triglyceride levels in some people, but this isn’t common. If your levels are already high, taking Pristiq could worsen them. Your doctor can advise you on whether Pristiq is safe for you to take if you have high cholesterol or triglyceride levels. If they prescribe Pristiq, they may monitor your levels more often than usual.

History of stroke or ministroke. Taking Pristiq can cause increases in your blood pressure. This can raise your risk of stroke or ministroke if you’ve had one in the past. Your doctor can determine if Pristiq is safe for you to take if you have history of stroke or ministroke.

Kidney or liver problems. After you take a dose of Pristiq, your kidneys and liver help remove the drug from your system. If you have kidney or liver problems, this may be harder for your body to do. So your doctor may prescribe a lower dose of Pristiq than usual. If your kidney or liver problems worsen during treatment, they may have you stop taking the drug. Your doctor may also recommend a different medication.

Low blood sodium levels. Treatment with Pristiq can cause low blood sodium levels in some people. You may have an increased risk of this side effect if you’re age 65 years or older or take a diuretic. If you already have low sodium levels, taking Pristiq could worsen your condition. Your doctor can help determine if Pristiq is safe for you to take.

Seizures and epilepsy. Some people reported seizures after taking Pristiq in clinical trials. The drug wasn’t studied in people who previously had seizures. So it’s not known whether Pristiq is safe for people with epilepsy or another condition that causes seizures. Your doctor can advise you on whether Pristiq is safe for you.

Allergic reaction. You should not take Pristiq If you’ve ever had an allergic reaction to Pristiq or any of its ingredients. Talk with your doctor about which other treatments are better choices for you.

Alcohol use with Pristiq

The manufacturer of Pristiq advises that you avoid drinking alcohol while taking the medication. Drinking alcohol may increase your risk of certain side effects of Pristiq, including:

• dizziness
• sexual problems*
• sleepiness

Drinking alcohol can also make depression worse. (Pristiq is approved to treat depression.)

Before you start treatment with Pristiq, tell your doctor if you drink alcohol. They can help develop the best treatment plan for your depression.

* For details, see the “Side effect specifics” section above.

Pregnancy and breastfeeding while taking Pristiq

Here’s some information about pregnancy, breastfeeding, and Pristiq.

Pregnancy. Pristiq has not been studied in pregnant people. Before you start taking Pristiq, tell your doctor if you’re pregnant or plan to become pregnant. They can advise you on the risks and benefits of Pristiq treatment.

Be sure to talk with your doctor if you become pregnant during your Pristiq treatment.

If you decide to take Pristiq while pregnant, talk with your doctor about joining the National Pregnancy Registry for Antidepressants. This registry helps identify effects that may occur when antidepressants are used during pregnancy. You can learn more by visiting the registry website.

Breastfeeding. Pristiq passes into human breast milk in low levels. But the drug has not been shown to cause side effects in a breastfed child.

If you’re breastfeeding or considering it, talk with your doctor. They can discuss the risks and benefits of taking Pristiq and recommend healthy ways to feed your child.

Like most medications, Pristiq can cause side effects. Most are mild and usually go away on their own after a few days to weeks. Pristiq can also cause some serious side effects. You should talk with your doctor if you have any side effects that last, are bothersome, or are serious.

Causes of nausea – Omega-Kyiv reference book

Nausea is one of the most painful conditions of the human body. The feeling of nausea does not allow you to fully enjoy life, spoils your appetite and inspires a feeling of weakness. Also, nausea is a symptom of many life-threatening diseases. If nausea does not go away after vomiting, but accompanies a person for more than a few days, you need to contact a medical center and undergo a comprehensive examination. Only diagnosis and accompanying symptoms can determine the cause of persistent nausea.

Causes of regular nausea:

• Taking medication. Some drugs, in addition to direct drug effects on the body, can cause side effects. One of the most common is nausea, lethargy and weakness. Nausea can be provoked by long-term use of anthelmintic and antiviral agents. Also, when treating with antibiotics, it is necessary to take a drug that normalizes the microflora of the stomach.

In addition to nausea, the disease is manifested by a metallic taste in the mouth and severe heartburn;
• Gastritis. The disease is a sign of inflammation of the gastric mucosa. Irritated stomach walls provoke a feeling of nausea, especially during or after eating. Gastritis must be treated with medication, as well as adhere to a special diet;
• Poisoning. This cause of nausea is the most common, as spoiled foods may not lose their own flavor and be eaten. When poisoned, a person is tormented by nausea, the urge to vomit, diarrhea, headache and a strong feeling of weakness. If the temperature rises sharply, you need to contact the clinic and undergo drug therapy;
• Arterial hypertension. Quite often, an increase in pressure in the blood vessels is accompanied by a feeling of nausea, and, consequently, weakness, dizziness and lack of appetite. After taking special medications that normalize blood pressure, the feeling of nausea disappears;
• Concussion. With severe bruising of the head, the patient is tormented by nausea and vomiting. The cause of the symptom is a disturbance in the normal functioning of the central nervous system;
• Pancreatitis. With inflammation of the pancreas, there is girdle pain, a feeling of nausea and lack of appetite;
• Vestibular apparatus. A weak vestibular apparatus is the cause of sudden nausea while traveling by car, bus and subway. It is especially difficult for such people to overcome the feeling of nausea during takeoff and landing;
• Intestinal infections. When infected with an intestinal infection, a person feels a strong feeling of nausea, accompanied by vomiting. In addition to these symptoms, there is severe abdominal pain, general weakness, and a fever may occur. Intestinal infections should not be treated on their own, you need to see a doctor and undergo drug therapy;
• Migraine. This neuralgic problem is characterized by severe, prolonged and regular pain, which is accompanied by a feeling of nausea and apathy;
• Cardiovascular diseases. With myocardial infarction, the blood supply to the body is disturbed, which entails sharp pain, a feeling of suffocation, lack of air and nausea;
• Fasting and diets. Girls who are on strict diets for a long time limit the body in the required amount of vitamins, proteins and carbohydrates. Nutritional deficiencies lead to exhaustion, nausea and loss of energy.

Nausea during critical days and during pregnancy

During the menstrual cycle, changes occur in a woman’s body, and intracranial pressure also increases. This is what causes constant nausea, vomiting, dizziness and a feeling of general weakness. A critical condition can last for several days, and then disappear without a trace until the next menstruation.

During pregnancy, the female body goes through a large number of hormonal changes.
