What Is Venlafaxine And What Does It Treat?
Venlafaxine is an antidepressant medication that works in the brain. It is approved for the treatment of major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder (social phobia).
Symptoms of depression include:
- Depressed mood – feeling sad, empty, or tearful
- Feeling worthless, guilty, hopeless, and helpless
- Loss of interest or pleasure in your usual activities
- Sleep and eat more or less than usual (for most people it is less)
- Low energy, trouble concentrating, or thoughts of death (suicidal thinking)
- Psychomotor agitation (‘nervous energy’)
- Psychomotor retardation (feeling like you are moving and thinking in slow motion)
- Suicidal thoughts or behaviors
Generalized Anxiety Disorder (GAD) occurs when a person experiences excessive anxiety or worry for at least six months. Other symptoms include:
- Fatigue (low energy, feeling tired all the time)
- Difficulty concentrating
- Muscle tension
- Sleep disturbance (difficulty falling asleep or waking up in the middle of the night)
Panic Disorder occurs when a person experiences unexpected and repeated episodes of intense fear. These episodes have physical symptoms including chest pain, shortness of breath, heart palpitations, sweating, dizziness, and nausea. Fear of future episodes is also part of panic disorder.
Social phobia/social anxiety disorder is a fear of situations where one may feel as if they are being judged by others. Symptoms include:
- Difficulty talking
Venlafaxine may also be helpful when prescribed “off-label” for attention-deficit/hyperactivity disorder (ADHD) in adults and children/adolescents, diabetic neuropathy, migraine prevention, hot flashes, obsessive compulsive disorder (OCD), posttraumatic stress disorder (PTSD), and premenstrual dysphoric disorder (PMDD) . “Off-label” means that it hasn’t been approved by the Food and Drug Administration for this condition. Your mental health provider should justify his or her thinking in recommending any “off-label” treatment. They should be clear about the limits of the research around that medication and if there are any other options.
What Is The Most Important Information I Should Know About Venlafaxine?
Do not stop taking venlafaxine, even when you feel better. With input from you, your health care provider will assess how long you will need to take the medicine.
Missing doses of venlafaxine may increase your risk for relapse in your symptoms.
Stopping venlafaxine abruptly may result in one or more of the following withdrawal symptoms: irritability, nausea, feeling dizzy, vomiting, nightmares, headache, and/or paresthesias (prickling, tingling sensation on the skin).
Depression is also a part of bipolar illness. People with bipolar disorder who take antidepressants may be at risk for “switching” from depression into mania. Symptoms of mania include “high” or irritable mood, very high self-esteem, decreased need for sleep, pressure to keep talking, racing thoughts, being easily distracted, frequently involved in activities with a large risk for bad consequences (for example, excessive buying sprees).
Medical attention should be sought if serotonin syndrome is suspected. Please refer to serious side effects for signs/symptoms.
Are There Specific Concerns About Venlafaxine And Pregnancy?
If you are planning on becoming pregnant, notify your health care provider to best manage your medications. People living with MDD who wish to become pregnant face important decisions. Untreated MDD has risks to the fetus, as well as the mother. It is important to discuss the risks and benefits of treatment with your doctor and caregivers. For women who take antidepressant medications during weeks 13 through the end of their pregnancy (second and third trimesters), there is a risk that the baby can be born before it is fully developed (before 37 weeks).
Caution is advised with breastfeeding since venlafaxine does pass into breast milk.
What Should I Discuss With My Health Care Provider Before Taking Venlafaxine?
- Symptoms of your condition that bother you the most
- If you have thoughts of suicide or harming yourself
- Medications you have taken in the past for your condition, whether they were effective or caused any adverse effects
- If you experience side effects from your medications, discuss them with your provider. Some side effects may pass with time, but others may require changes in the medication.
- Any other psychiatric or medical problems you have, including a history of bipolar disorder
- All other medications you are currently taking (including over the counter products, herbal and nutritional supplements) and any medication allergies you have
- Other non-medication treatment you are receiving, such as talk therapy or substance abuse treatment. Your provider can explain how these different treatments work with the medication.
- If you are pregnant, plan to become pregnant, or are breastfeeding
- If you drink alcohol or use drugs
How Should I Take Venlafaxine?
Venlafaxine immediate release tablets are usually taken two or three times per day with or without food. The extended release tablets and capsules are taken one time per day with or without food.
Typically patients begin at a low dose of medicine and the dose is increased slowly over several weeks.
The dose usually ranges from 37.5 mg to 300 mg. Only your health care provider can determine the correct dose for you.
Extended release tablets: swallow whole; do not chew, crush, or break
Extended release capsules: swallow whole or sprinkle onto food, such as applesauce or pudding and eat immediately.
Consider using a calendar, pillbox, alarm clock, or cell phone alert to help you remember to take your medication. You may also ask a family member or friend to remind you or check in with you to be sure you are taking your medication.
What Happens If I Miss A Dose Of Venlafaxine?
If you miss a dose of venlafaxine, take it as soon as you remember, unless it is closer to the time of your next dose. Discuss this with your health care provider. Do not double your next dose or take more than what is prescribed.
What Should I Avoid While Taking Venlafaxine?
Avoid drinking alcohol or using illegal drugs while you are taking antidepressant medications. They may decrease the benefits (e.g., worsen your condition) and increase adverse effects (e.g., sedation) of the medication.
What Happens If I Overdose With Venlafaxine?
If an overdose occurs, call your doctor or 911. You may need urgent medical care. You may also contact the poison control center at 1-800-222-1222.
A specific treatment to reverse the effects of venlafaxine does not exist.
What Are The Possible Side Effects Of Venlafaxine?
Common side effects
- Headache, nausea, diarrhea, dry mouth, increased sweating
- Feeling nervous, restless, fatigued, sleepy or having trouble sleeping (insomnia)
These will often improve over the first week or two as you continue to take the medication.
- Sexual side effects, such as problems with orgasm or ejaculatory delay
- Increased blood pressure
These often do not improve over time.
Rare/serious side effects
Increased heart rate, low blood pressure, increased salivation, irregular menstrual cycle, increased frequency of urination, changes in taste, low sodium (symptoms of low sodium levels may include headache, weakness, difficulty concentrating and remembering), teeth grinding, difficulty urinating, angle closure glaucoma (symptoms of angle closure glaucoma may include eye pain, changes in vision, swelling or redness in or around eye).
Serotonin syndrome (symptoms may include shivering, diarrhea, confusion, severe muscle tightness, fever, seizures, and death)
SNRI antidepressants including venlafaxine may increase the risk of bleeding events. Combined use of aspirin, nonsteroidal anti-inflammatory drugs (e.g., ibuprofen, naproxen), warfarin, and other anti-coagulants may increase this risk. This may include gums that bleed more easily, nose bleed, or gastrointestinal bleeding. Some cases have been life threatening.
Are There Any Risks For Taking Venlafaxine For Long Periods Of Time?
To date, there are no known problems associated with long term use of venlafaxine. It is a safe and effective medication when used as directed.
What Other Medications May Interact With Venlafaxine?
Venlafaxine should not be taken with or within 2 weeks of taking monoamine oxidase inhibitors (MAOIs). These include phenelzine (Nardil®), tranylcypromine (Parnate®), isocarboxazid (Marplan®), rasagiline (Azilect®), and selegiline (Emsam®).
Although rare, there is an increased risk of serotonin syndrome when venlafaxine is used with other medications that increase serotonin, such as other antidepressants, migraine medications called “triptans” (e.g., Imitrex®), some pain medications (e.g., tramadol (Ultram®), and the antibiotic linezolid (Zyvox®).
Venlafaxine may increase the effects of other medications that can cause bleeding (e. g., ibuprofen (Advil®, Motrin®), warfarin (Coumadin®) and aspirin).
How Long Does It Take For Venlafaxine To Work?
Sleep, energy, or appetite may show some improvement within the first 1-2 weeks. Improvement in these physical symptoms can be an important early signal that the medication is working. Depressed mood and lack of interest in activities may need up to 6-8 weeks to fully improve.
Summary of FDA Black Box Warnings
Suicidal thoughts or actions in children and adults
Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications. This risk may persist until significant remission occurs.
In short-term studies, antidepressants increased the risk of suicidality in children, adolescents, and young adults when compared to placebo. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24. Adults age 65 and older taking antidepressants have a decreased risk of suicidality. Patients, their families, and caregivers should be alert to the emergence of anxiety, restlessness, irritability, aggressiveness and insomnia. If these symptoms emerge, they should be reported to the patient’s prescriber or health care professional. All patients being treated with antidepressants for any indication should watch for and notify their health care provider for worsening symptoms, suicidality and unusual changes in behavior, especially during the first few months of treatment.

FDA – Effexor
NIH – Venlafaxine
Last Updated: Jan 8, 2021
Warnings of Effexor (Venlafaxine) for Depression
Venlafaxine is an antidepressant drug in a class called serotonin-norepinephrine reuptake inhibitors (SNRIs). It is an oral tablet that comes in both an immediate-release (Effexor) and extended-release (Effexor XR) formula. Both are used to treat depression in addition to a variety of other mental health conditions.
SNRIs work by blocking the reabsorption (or reuptake) of serotonin and norepinephrine back into the nerve cells that released them. Blocking their reuptake increases the levels of these neurotransmitters in the brain. This improves your focus and alertness and boosts your mood.
Effexor has been discontinued in the U.S., but Effexor XR is still available by prescription. Unlike Effexor, Effexor XR only needs to be taken once a day.
Common Side Effects
Like any medication, side effects may occur while taking Effexor. Be sure to contact your doctor if they don’t go away or become bothersome. Common side effects include:
- Feeling tired
- Loss of appetite
- Sexual side effects
These side effects often improve over the first week or two as you continue taking the medication. Call your doctor if your symptoms become severe or don’t go away.
Effexor should not be taken with or within two weeks of taking monoamine oxidase inhibitors (MAOIs). Examples of MAOIs include:
- Emsam (selegiline)
- Marplan (isocarboxazid)
- Nardil (phenelzine)
- Parnate (tranylcypromine)
Serious and even fatal complications may result from such a combination.
Make sure your doctor knows your complete medical history. Effexor should be used with caution if you have:
- Brain disease or damage, or a history of seizures: The risk of seizures may be increased when taking Effexor.
- Heart disease or high or low blood pressure: Effexor may occasionally make these conditions worse.
- History of mania: The risk of developing mania may be increased while taking Effexor. Obviously, this is very important for bipolar patients to watch for.
- Kidney disease or liver disease: Higher blood levels of Effexor may occur, increasing the chance of side effects. Your doctor may need to adjust your dose.
Warnings and Interactions
Warnings are established to both ensure the safe use and discontinuation of Effexor. Your doctor should monitor you for the following complications while you’re taking Effexor.
Be careful when mixing Effexor with other medicines that also affect serotonin levels, such as other antidepressants, lithium, and St. John’s wort. Doing so can lead to an excessive serotonin buildup in the brain. This can cause a condition called serotonin syndrome.
Symptoms of serotonin syndrome include:
- Dilated pupils
- Loss of muscle coordination
- Muscle stiffness
- Sudden spikes in blood pressure or heart rate
- Sweating or shivering
- Twitching muscles
- Unusual agitation or restlessness
Some cases of serotonin syndrome can be life-threatening. If you’re taking Effexor and experience any of these symptoms, contact your doctor as soon as possible.
Risk of Overdose
You should always avoid drinking or using other drugs while you’re taking Effexor. These substances may decrease the benefits of the medication, or they can result in a toxic overdose. The most common Effexor overdose effects include:
- Changes in consciousness (ranging from sleepiness to coma)
- Dilated pupils
- Fast heart rate
To reduce your risk of overdose, your doctor will only prescribe you the lowest possible dose in the smallest quantity.
Suicidal Thoughts and Actions
Children and adolescents (up to age 25) may experience increased suicidal thoughts and behaviors when taking antidepressant medications. The danger is greatest the first few months of treatment or when changing the dose.
Though this warning is true for all antidepressants, taking Effexor may increase your risk even more. A major study found that Effexor was associated with a higher risk of both completed and attempted suicide compared with other antidepressants, including Celexa (citalopram), Prozac (fluoxetine), and Prothiaden (dothiepin).
Stopping Effexor abruptly may result in one of more of the following withdrawal symptoms:
- Anxiety or worsening of depression
- Gastrointestinal upset
- Paresthesias (prickling, tingling sensation on the skin)
It’s important to not stop taking Effexor on your own. If you and your doctor decide it’s best for you to stop Effexor, they can provide you with a tapering strategy to minimize any withdrawal symptoms
A Word From Verywell
Before prescribing Effexor, your doctor will take a thorough medical history. Even so, it’s important for you to play an active role in your care. Be sure to share every detail of your health history, regardless of whether or not you think it’s important.
Overall, Effexor is a well-tolerated medication that has helped many people cope with a variety of mental health conditions. You deserve to get well. The good news is that if Effexor doesn’t help, there are lots of other options to try.
Venlafaxine: MedlinePlus Drug Information
A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants (‘mood elevators’) such as venlafaxine during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take venlafaxine, but in some cases, a doctor may decide that venlafaxine is the best medication to treat a child’s condition.
You should know that your mental health may change in unexpected ways when you take venlafaxine or other antidepressants even if you are an adult over 24 years of age. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.
Your healthcare provider will want to see you often while you are taking venlafaxine, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.
The doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with venlafaxine. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can obtain the Medication Guide from the FDA website: http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm.
No matter your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.
Safety Info | EFFEXOR XR® (venlafaxine HCl)
Suicidality and Antidepressant Drugs
Antidepressants increased the risk of suicidal thinking and behavior (suicidality) in children, teens, and young adults compared to placebo. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Effexor XR is not approved for use in children and teens.
Do not take EFFEXOR XR if you:
- Are allergic to Effexor XR or any of the ingredients in Effexor XR
- Have uncontrolled angle-closure glaucoma
- Currently take, or have taken within the last 14 days, any medicine known as an MAOI such as linezolid or methylene blue. Do not take an MAOI within 7 days of stopping Effexor XR. Ask your doctor or pharmacist if you are not sure if your medicine is an MAOI
All patients taking antidepressants should be watched closely for signs that their condition is getting worse or that they are becoming suicidal, especially when they first start therapy, or when their dose is increased or decreased. Patients should also be watched for becoming agitated, irritable, hostile, aggressive, impulsive, or restless. Such symptoms should be reported to the patient’s doctor right away.
Before taking Effexor XR, tell your doctor and pharmacist about all prescription and over-the-counter medications and supplements you take or plan to take, including those to treat migraines or psychiatric disorders (including other antidepressants or amphetamines) to avoid a potentially life-threatening condition called serotonin syndrome.
Effexor XR may raise blood pressure in some patients. Your blood pressure should be controlled before starting treatment and should be monitored regularly.
Taking Effexor XR with aspirin, nonsteroidal anti-inflammatory drugs, warfarin, or other blood thinners may increase the risk of bleeding events.
Some people are at risk for visual problems such as eye pain, changes in vision, or swelling or redness around the eye. You may want to undergo an eye examination to see if you are at risk and get preventative treatment if you are.
When people suddenly stop using or quickly lower their daily dose of Effexor XR, serious discontinuation symptoms may occur. Talk to your doctor before discontinuing or reducing your dose of Effexor XR.
Pregnant or nursing women shouldn’t take any antidepressant without consulting their doctor.
Until you see how Effexor XR affects you, be careful doing such activities as driving a car or operating machinery. Avoid drinking alcohol while taking Effexor XR.
In clinical studies, the most common side effects with Effexor XR (reported in at least 5% of patients and at least twice as often as with placebo) were constipation, dizziness, dry mouth, insomnia, loss of appetite, nausea, nervousness, sexual side effects, sleepiness, sweating, and weakness.
Effexor XR extended-release capsules are a prescription medicine indicated for the treatment, in adults, of Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), and Panic Disorder (PD) with or without agoraphobia.

Effexor XR – Uses, Side Effects, Interactions
How does this medication work? What will it do for me?
Venlafaxine belongs to the class of antidepressant and anxiolytic medications known as serotonin and norepinephrine reuptake inhibitors (SNRIs). It is used to treat depression. It works on the central nervous system (CNS) to elevate mood in people with depression.
Venlafaxine is also used to treat the symptoms of anxiety causing distress in generalized anxiety disorder (GAD), social anxiety disorder (social phobia), and panic disorder (panic attacks). SNRIs work by increasing the amount of two chemicals called serotonin and norepinephrine, which are available in certain parts of the brain.

Participants who find relief from depressive symptoms on venlafaxine XR alone will drop out of the study.Participants who respond incompletely (those still feeling depressed or withdrawn). buprenorphine or placebo increase venlafaxine xr by 8 weeks (phase 2) to achieve remission. Subjects will start at 0.2 mg and increase the dose to 1.2 mg as needed. Subjects can have up to 2 MRI scans at the beginning and end of Phase 2, as well as cognitive testing at the same time points. At the end of Phase 2, the blind will be broken for all participants. The participants who took the placebo were able to start taking buprenorphine immediately for phase 3 (approximately 8 weeks).Participants who have already taken buprenorphine in Phase 2 may continue to take buprenorphine during Phase 3. Buprenorphine (BPN) will be reduced upon withdrawal from the PI study. Phase 3 options will allow all participants to experience the benefits of buprenorphine (RBN). Efficacy and tolerability data will provide clinically relevant information. assessing the benefits and risks of increasing buprenorphine for the treatment of elderly persistent depression (LL-TRD). We randomize approximately 20 subjects into Phase 2.In addition, we will collect plasma buprenorphine (BPN) levels from all randomized patients to study dose-response relationships. A small pilot study (aged 21 years and older) with up to 15 healthy control subjects will be studied. for about 2 weeks to make sure all of our treatments are working and to determine if there are clinical effects from buprenorphine.

Polyneuropathy – treatment, symptoms, causes, diagnosis
Polyneuropathy, or peripheral neuropathy, results from damage to peripheral nerves and often results in symptoms such as weakness, numbness, and pain, usually in the arms and legs. But polyneuropathy can also affect other parts of the body.Peripheral neuropathy can develop in one nerve (mononeuropathy), two or more nerves in different areas, or many nerves can be involved (polyneuropathy).
The peripheral nervous system transmits information from the brain and spinal cord (central nervous system) to the rest of the body. Peripheral neuropathy can result from traumatic injury, infection, metabolic disorders, hereditary causes, and exposure to toxins. Diabetes mellitus is one of the most common causes of polyneuropathy.
Patients with peripheral neuropathy usually describe pain as a tingling or burning sensation. In many cases, symptoms are reduced if compensation for the underlying disease occurs.
Each nerve in the peripheral nervous system has a specific function, so the symptoms depend on the type of nerves that are damaged. Nerves are classified into:
- Sensory nerves that receive sensations from the skin, such as temperature, pain, vibration or pressure
- Motor (motor) nerves that control muscle movements
- Autonomic nerves, which control functions such as blood pressure, heart rate, digestion and bladder function
Symptoms of polyneuropathy, may include:
- Gradual onset of numbness and tingling in the legs or arms, which can spread up the arms and legs
- Acute stabbing or burning pain
- Increased touch sensitivity
- Lack of coordination and falling
- Muscle weakness or paralysis if motor nerves are damaged
If autonomic nerves are involved, symptoms may include:
- Heat intolerance and changes in sweating
- Problems with digestion, bladder or intestines
- Changes in blood pressure resulting in dizziness
A number of factors can lead to the development of neuropathy, including:
- Alcoholism.A poor diet can lead to vitamin deficiencies.
- Autoimmune diseases. These include diseases such as Sjogren’s syndrome, systemic lupus erythematosus, rheumatoid arthritis, Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, and necrotizing vasculitis.
- Diabetes. More than half of people with diabetes develop some type of neuropathy.
- Exposure to poisons. Toxic substances include heavy metals or chemicals.
- Medicines. Certain medications, especially those used to treat cancer (chemotherapy), can cause peripheral neuropathy.
- Infection. These include some viral or bacterial infections, including Lyme disease, shingles, Epstein-Barr virus, hepatitis C, leprosy, diphtheria, and HIV.
- Hereditary diseases. For example, a disease such as Charcot-Marie’s disease is a hereditary type of neuropathy.
- Injury or compression to the nerve. Injuries such as road accidents, falls, or sports injuries can damage or even rupture peripheral nerves. Nerve compression can occur with constant exposure to peripheral nerves.
- Tumors. Malignant and benign tumors can damage or put pressure on nerves.
- Vitamin deficiency. B vitamins, including B-1, B-6 and B-12, vitamin E and niacin are important for nerves.
- Diseases of the bone marrow. These include the presence of abnormal protein in the blood (monoclonal gammopathies), multiple myeloma, lymphoma, and amyloidosis.
- Other diseases. These include kidney disease, liver disease, connective tissue disease, and thyroid disease (hypothyroidism).
Complications of polyneuropathy may include
- Burns and skin injuries. If there is numbness in parts of the body, the patient may not feel temperature changes or pain.
- Infection. Feet and other areas of the body with reduced sensitivity can be invisibly damaged. It is necessary to monitor the integrity of the skin, especially if there is diabetes mellitus, since even minor skin lesions can lead to tissue infection.
When diagnosing polyneuropathy, doctors may be primarily interested in the answers to the following questions
- Does the patient have a medical condition such as diabetes or kidney disease?
- When did the symptoms start?
- Were the symptoms persistent or episodic?
- How severe are the symptoms?
- What causes an increase or decrease in symptoms?
- Did anyone in the patient’s family have similar symptoms?
- The doctor needs a complete medical history.The doctor will review the medical history, including symptoms, the patient’s lifestyle, exposure to toxins, bad habits, and a family history of neurological disease.
- During a neurological examination, the physician may check tendon reflexes, muscle strength and tone, ability to sense certain sensations, and coordination.
The doctor can order an examination
- Imaging CT or MRI can detect a variety of diseases (including tumors).
- Neurophysiology. Electromyography records electrical activity in muscles, which can help determine if symptoms, including weakness, are caused by muscle damage or nerve damage. ENMG checks the conduction of the impulse along the nerves and allows you to determine the degree of damage to the nerve fibers. Neurophysiological studies of the autonomic nervous system – sensory tests that record how the patient feels touch, vibration, cold and warmth – can also be done.
- Nerve biopsy. The doctor may recommend removing a small part of the nerve, usually the sensory nerve, to examine the morphological changes in the nerve in order to determine the cause of the nerve damage.
- Skin biopsy. In this test, a small portion of the skin is removed to examine the number of nerve endings. A decrease in the number of nerve endings indicates neuropathy.
- Laboratory research methods are required to rule out various diseases such as diabetes mellitus, autoimmune kidney disease, etc.D.
The goal of polyneuropathy treatment is to treat the underlying disease and minimize symptoms. If laboratory tests and other methods of examination indicate the absence of the underlying disease, the doctor may recommend expectant tactics in order to see if there is an independent reduction in the symptoms of neuropathy. If there is exposure to toxins or alcohol, your doctor will recommend avoiding these substances.
Medicines used to relieve pain in polyneuropathy include:
- Pain relievers such as paracetamol or NSAIDs reduce pain
- Medicines containing opioids, such as tramadol (Conzip, Ultram ER, and others) or oxycodone (Oxycontin, Roxicodone, and others), can lead to dependence and addiction, so these drugs are usually only prescribed when other methods treatments have no effect.
- Anticonvulsants. Medicines such as gabapentin (Gralise, Neurontin) and pregabalin (Lyrica), synthesized to treat epilepsy, can significantly reduce pain in neuropathy. Side effects of these drugs may include drowsiness and dizziness.
- Capsaicin. A cream containing this substance (found naturally in hot peppers) can be used to provide some relief from neuropathy symptoms. But given the irritating effect of capsaicin on the skin, not all patients can tolerate the effects of capsaicin creams.
- Antidepressants. Certain tricyclic antidepressants, such as amitriptyline, doxepin, and nortriptyline (Pamelor), can be used to reduce pain in neuropathy by acting on the central nervous system.
- The serotonin and norepinephrine reuptake inhibitor duloxetine (Cymbalta) and the antidepressant venlafaxine (Effexor XR) may also relieve pain in peripheral neuropathy associated with diabetes. Side effects may include dry mouth, nausea, drowsiness, dizziness, decreased appetite, and constipation.
- Intravenous immunoglobulin is the mainstay of treatment for chronic inflammatory demyelinating polyneuropathy and other inflammatory neuropathies.
- Alpha Lipoic Acid. It has been used for the treatment of peripheral neuropathy in Europe for many years. This antioxidant helps reduce symptoms. Talking to your doctor about alpha lipoic acid intake may affect blood sugar levels. Other side effects can include stomach upset and skin rashes.
- Herbs. Certain herbs, such as evening primrose oils, can help reduce neuropathic pain in diabetic patients.
- Amino Acids. Amino acids such as acetyl-L-carnitine may help improve symptoms of peripheral neuropathy in chemotherapy and diabetes patients. Side effects may include nausea and vomiting.
In addition to drug treatment, other methods of treatment may be used.
- Myostimulation allows, to a certain extent, to restore the conduction of a nerve impulse through the muscles.
- Plasmapheresis and intravenous immunoglobulin.
- exercise therapy. In the presence of muscle weakness, exercise can improve muscle strength and tone. Regular exercise, such as walking three times a week, can reduce neuropathy pain, improve muscle strength, and help control blood sugar levels. Exercises such as yoga and tai chi can also be quite effective.
- Acupuncture. The impact on biologically active points can improve the sensitivity of nerve receptors and reduce pain.
Advice for patients with polyneuropathy
- Feet needs to be taken care of, especially if you have diabetes. Check your feet daily for blisters, cuts, or calluses. Wear soft, loose cotton socks and soft boots.
- It is necessary to quit smoking. Smoking can affect blood circulation in the extremities, increasing the risk of foot problems and other complications of neuropathy.
- Eat healthy food.A healthy diet is especially important to ensure that the patient gets the vitamins and minerals they need.
- Drinking alcohol should be avoided. Alcohol can worsen the symptoms of polyneuropathy.
- Monitoring blood glucose levels in the presence of diabetes mellitus will keep blood glucose levels under control and may help improve the course of neuropathy.

How to treat depression? – Medical center for xenon therapy XeMed
Treatments for depression are medication, talk therapy (where a person talks to an experienced professional about their thoughts and feelings; sometimes referred to as “psychotherapy”), or a combination of the two.
In this essay, only the drug therapy used to treat depression, the so-called antidepressants, will be considered. Your doctor may prescribe psychotherapy in addition to your medications. Always ask your doctor about the benefits and risks of adding psychotherapy to your treatment regimen.
What do the letters CP, CR, XR, and XL stand for after the brand name of an antidepressant?
Labels on antidepressant packages indicate the duration of action in the human body.This means that the drug stays in the body for a longer period of time and you may need to take the drug less frequently.
Wellbatrin SR® is a sustained release drug. You can take this medication twice a day.
Paxil CR® is a controlled release drug. You use this medicine once a day.
Effexor XR®, Wellbatrin XL®, and Prozac Weekly® are extended release formulations. You can take Wellbutrin XL® and Effexor XR® once a day.As for Prozac Weekly®, it can be taken once a week.

What does research say about how these drugs help people with depression?
All antidepressants are aimed at reducing the symptoms of depression and improving the quality of life of people with depression.
All antidepressants prevent the recurrence of symptoms of depression.
What is the effectiveness of antidepressants?
Although all antidepressants work in much the same way, it is important to remember that some people will not feel better the first time they take the drug. They may need to try several medications before finding one that works for them. Others may find that the symptoms have returned, although the drug helped at first. It is important to carefully follow your doctor’s instructions to find a medication that will work.
Only three out of five report improvement after the first dose of an antidepressant.
What did the study find about specific antidepressants?
Studies have shown specific benefits of several medicines:
People who took Mirtazapine (Remeron®) felt better earlier than if they were taking other antidepressants. Remeron® is effective in one to two weeks. All other antidepressants after 4 weeks at the earliest.
Prozac Weekly® and Paxil CR® worked as efficiently as conventional Prozac® and Paxil®.
Fewer people are taking Venlafaxine (Effexor®, Effexor XR®) because it is less effective than other antidepressants. Side effects such as nausea and vomiting were also the reason for the rejection of Venlafaxine.
