Phentermine and topiramate extended-release (long-acting) capsules are used to help adults who are obese or who are overweight and have weight-related medical problems to lose weight and to keep from gaining back that weight. Phentermine and topiramate extended-release (long-acting) capsules are also used to help children aged 12 years or older who have a body mass index (BMI) in the 95th percentile or greater based on age and sex standards. Phentermine and topiramate extended-release capsules must be used along with a reduced calorie diet and exercise plan. Phentermine is in a class of medications called anorectics. It works by decreasing appetite. Topiramate is in a class of medications called anticonvulsants. It works by decreasing appetite and by causing feelings of fullness to last longer after eating.

Phentermine and topiramate come as extended-release capsules to take by mouth. The medication is usually taken with or without food once a day in the morning. This medication may cause difficulty falling asleep or staying asleep if it is taken in the evening. Take phentermine and topiramate at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take phentermine and topiramate exactly as directed.

Your doctor will probably start you on a low dose of phentermine and topiramate and increase your dose after 14 days. After you take this dose for 12 weeks, your doctor will check to see how much weight you have lost. If you have not lost a certain amount of weight, your doctor may tell you to stop taking phentermine and topiramate or may increase your dose and then increase it again after 14 days. After you take the new dose for 12 weeks, your doctor will check to see how much weight you have lost. If you have not lost a certain amount of weight, it is not likely that you will benefit from taking phentermine and topiramate, so your doctor will probably tell you to stop taking the medication.

Phentermine and topiramate may be habit forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor.

Phentermine and topiramate will help control your weight only as long as you continue to take the medication. Do not stop taking phentermine and topiramate without talking to your doctor. If you suddenly stop taking phentermine and topiramate, you may experience seizures. Your doctor will tell you how to decrease your dose gradually.

Phentermine and topiramate is not available at retail pharmacies. This medication is available only through specific mail order pharmacies. Ask your doctor if you have any questions about how you will receive your medication.

Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with phentermine and topiramate and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer’s website to obtain the Medication Guide.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking phentermine and topiramate,

Drink extra fluids during your treatment with phentermine and topiramate.

Unless your doctor tells you otherwise, continue your normal diet.

Skip the missed dose and take your usual dose the next morning. Do not take a double dose to make up for a missed one.

Phentermine and topiramate may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

  • headache
  • dizziness
  • numbness, burning, or tingling in the hands, feet, face, or mouth
  • decreased sense of touch or ability to feel sensation
  • difficulty concentrating, thinking, paying attention, speaking, or remembering
  • excessive tiredness
  • dry mouth
  • unusual thirst
  • changes or decreased ability to taste food
  • diarrhea
  • constipation
  • heartburn
  • painful menstrual periods
  • pain in the back, neck, muscles, arms or legs
  • tightening of the muscles
  • painful, difficult, or frequent urination
  • hair loss

Some side effects can be serious.

If you experience any of these symptoms, call your doctor immediately or get emergency medical treatment:

  • racing or pounding heartbeat that lasts several minutes
  • sudden decrease in vision
  • eye pain or redness
  • fast, shallow breathing
  • severe pain in the pack or side
  • blood in urine
  • rash or blisters, especially if you also have fever
  • hives

Phentermine and topiramate may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Store phentermine and topiramate in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many capsules are left so you will know if any are missing.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call emergency services at 911.

Symptoms of overdose may include the following:

  • restlessness
  • uncontrollable shaking of a part of the body
  • fast breathing
  • confusion
  • aggressiveness
  • hallucinations (seeing things or hearing voices that do not exist)
  • panic

  • irregular heartbeat
  • nausea
  • vomiting
  • diarrhea
  • stomach pain or cramps
  • seizures
  • coma (loss of consciousness for a period of time)
  • dizziness
  • speech disturbances
  • blurred or double vision
  • problems with coordination
  • Qsymia® (containing Phentermine, Topiramate)

Top phentermine alternatives and how to switch your Rx

Phentermine doesn’t work for everyone. Contrave, Lomaira, Mounjaro, Saxenda, and Wegovy are some phentermine alternatives.

Phentermine is a prescription drug used along with diet and exercise for the short-term (several weeks) treatment of obesity in adults. Phentermine may be prescribed in patients with an initial body mass index (BMI) of 30 kg/m2 or more—or patients with a BMI of 27 kg/m2 who also have other risk factors such as high blood pressure, diabetes, or high cholesterol. 

Phentermine, first approved by the U.S. Food and Drug Administration (FDA) in 1959, is available as an oral tablet and capsule. Phentermine is usually dispensed as a generic drug but is also commonly referred to by its brand name, Adipex-P.

Phentermine is part of a drug class called sympathomimetic amine anorectics. Phentermine works by decreasing the appetite (an appetite suppressant) which helps in reducing food cravings and increasing your metabolic rate to aid in fat loss. To do so, phentermine stimulates the neurotransmitters in the central nervous system to suppress feelings of hunger. It is a Schedule IV controlled substance. This means it has the potential for abuse and dependence. Phentermine is chemically related to the ADHD drug amphetamine and other central nervous system (CNS) drugs that are often abused. Because of this, healthcare professionals will weigh the risk of abuse before prescribing phentermine as a weight loss pill. When phentermine is prescribed, its monthly supply is generally prescribed in small amounts to lessen the risk of an overdose.

Sometimes, an individual may seek a different treatment than phentermine. Some patients may not see the desired effects of phentermine and may want to seek the best alternative to see if a different drug is more effective. Or, because phentermine is only approved as a short-term treatment, certain patients may want to seek the best phentermine alternatives that can be used for more extended periods of time.

Others may experience side effects that are bothersome or do not go away. Some of the common adverse effects of the prescription phentermine include:

  • Heart palpitations
  • Fast heart rate
  • Increased blood pressure
  • Restlessness 
  • Trouble sleeping
  • Dizziness 
  • Euphoria (feeling intensely excited and happy)
  • Dysphoria (feeling uneasy, unhappy, or unwell)
  • Tremor
  • Headache 
  • Dry mouth 
  • Unpleasant taste in the mouth
  • Constipation or diarrhea
  • Hives
  • Sexual problems such as impotence (difficulty achieving or maintaining an erection) or changes in libido

In some cases, a serious side effect may occur. Severe side effects may include blocked blood flow to the heart, fast heart rate, hypertension (high blood pressure), or pulmonary hypertension (high blood pressure in the lungs).  

Some individuals cannot take phentermine at all. Individuals with a history of substance use disorder may not be appropriate candidates for phentermine. Other individuals that should not take phentermine include:

  • People with an allergy to phentermine, amphetamine, or any CNS stimulant drug
  • People who have taken a drug in the monoamine oxidase inhibitor (MAOI) class of drugs within the past 14 days
  • Women who are pregnant or breastfeeding
  • People with severe kidney problems or on dialysis
  • People with certain blood vessel or heart conditions (or a history of heart conditions)
  • People with high blood pressure that is not controlled by medication
  • People with hyperthyroidism (overactive thyroid)
  • People with glaucoma
  • People in an agitated state

For patients seeking an effective phentermine alternative, there are other medications for weight loss that can be discussed with a healthcare professional.  

What can I take in place of phentermine?

If you are looking for a phentermine alternative, other types of medications are available. The table below compares phentermine (in bold) with common alternatives. All of the weight loss drugs listed are FDA-approved prescription medications. One of these options may be more suitable for certain individuals due to different side effect profiles or dosing schedules.

Other alternatives to phentermine

  • Alli (orlistat OTC)
  • Benzphetamine
  • Diethylpropion extended-release
  • Evekeo (amphetamine)
  • Ozempic (semaglutide): as an off-label use
  • Phendimetrazine 
  • Phendimetrazine extended-release
  • Victoza (liraglutide): as an off-label use
  • Xenical (orlistat Rx) 

Top 5 phentermine alternatives

The following are some of the most common alternatives to phentermine.

1. Contrave (naltrexone and bupropion) oral tablet

Contrave contains two ingredients. Naltrexone, an opioid antagonist, and bupropion, an antidepressant, work on two areas of the brain that are involved in the appetite and reward system. While phentermine is approved for short term-use, Contrave is used for long-term treatment. Contrave should be used along with a healthy diet and exercise. It can be used in adults with a BMI of 30 kg/m2—or adults with a BMI of 27 kg/m2 or more with at least one weight-related risk factor such as high blood pressure, high cholesterol, or Type 2 diabetes. 

Common side effects include nausea, constipation, diarrhea, headache, vomiting, dizziness, trouble sleeping, and dry mouth. 

Contrave has a black box warning, the strongest warning required by the FDA. The black box warning is due to the antidepressant ingredient in Contrave, bupropion. Patients who take Contrave should be closely monitored for changes in mood and behavior or suicidal thoughts and behaviors. Contrave should never be used in children or adolescents under 18 years old.

2. Lomaira (phentermine) oral tablet

Lomaira is a brand-name drug that contains phentermine, but in an 8 mg dose—a smaller dose that is taken three times daily—rather than the typical generic phentermine dose, which is generally a larger dose taken once daily. Lomaira is only available under the brand name. There is no equivalent generic 8 mg phentermine. Like phentermine, Lomaira is approved for the short-term treatment of obesity in combination with diet and exercise. 

Common side effects of Lomaira are the same as generic phentermine in larger doses and include heart palpitations, fast heart rate, increased blood pressure, dizziness, trouble sleeping, euphoria, dysphoria, headache, dry mouth, stomach problems, hives, and sexual problems.

3. Mounjaro (tirzepatide) injection 

Mounjaro is currently approved for adults with Type 2 diabetes—combined with diet and exercise, Mounjaro helps control blood sugar levels. Currently, many healthcare professionals prescribe Mounjaro off-label for weight loss. Off-label prescribing is when a drug is prescribed for a use not approved by the FDA. 

In a study called the SURMOUNT-1 trial, Mounjaro was found to help participants lose a significant amount of weight. In October 2022, the FDA gave Mounjaro a Fast Track designation to be studied for weight loss. A Fast Track designation means that the medication review and approval process will occur faster than usual to fulfill an unmet medical need. 

Mounjaro, taken as a once-weekly injection, is classified as a glucose-dependent insulinotropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor agonist. While other injectable drugs approved for Type 2 diabetes or weight loss are GLP-1 receptor agonists, Mounjaro is the first GIP and GLP-1 receptor agonist.

Common side effects include appetite loss as well as stomach problems such as nausea, vomiting, diarrhea or constipation, indigestion, and stomach pain.  

Because Mounjaro affects stomach emptying, women who take oral contraceptives (birth control pills) should use a barrier method of birth control (such as condoms) or another form of effective birth control for 4 weeks after starting Mounjaro, and for 4 weeks after every dose increase. Women can discuss effective forms of birth control with their healthcare provider.

Mounjaro has a black box warning. The warning, which applies to any drug that contains a GLP-1 agonist, states that the drug causes thyroid C-cell tumors in rats. However, it is not known if Mounjaro can cause thyroid cancers in humans. Mounjaro should not be used in people with a history (or family history) of medullary thyroid carcinoma or in people with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Individuals who take Mounjaro should be alert to symptoms of thyroid tumors (such as a lump in the neck, hoarseness, shortness of breath, or trouble swallowing) to their healthcare provider right away. 


Saxenda (liraglutide) injection

Saxenda is a GLP-1 receptor agonist that contains the ingredient liraglutide. It is approved for long-term weight management in combination with diet and exercise in adults with a BMI of 30 kg/m2—or adults with a BMI of 27 kg/m2 or more with at least one weight-related risk factor. It can also be used in adolescents 12 years and older who weigh more than 60 kg (132 lbs) and have an initial BMI corresponding to 30 kg/m2 in adults. 

Common side effects of Saxenda include stomach problems, including nausea, vomiting, diarrhea or constipation, indigestion, stomach pain, and stomach virus. Other common side effects may include injection site reactions, headache, tiredness, dizziness, and fever. Hypoglycemia (low blood sugar) may occur in patients with Type 2 diabetes who also use insulin or certain diabetes medications. 

Because Saxenda affects stomach emptying, ask your healthcare provider when you should time any oral medications.

Saxenda has the same black box warning as Mounjaro and should not be used in people with a history or family history of thyroid cancers. Patients who take Saxenda should be alert to symptoms of thyroid cancer.

5. Wegovy (semaglutide) injection

Wegovy is another GLP-1 agonist and is one of the newer drugs approved for weight loss. Wegovy contains the ingredient semaglutide. Wegovy is a weekly injection that is FDA-approved for long-term weight management (in combination with diet and exercise) in adults with a BMI of 30 kg/m2—or adults with a BMI of 27 kg/m2 or more with at least one weight-related risk factor. 

Common side effects include stomach problems such as nausea, vomiting, diarrhea or constipation, stomach pain, bloating, indigestion, gas, burping, reflux, and stomach virus. Other common Wegovy side effects may include low blood sugar (especially in those with Type 2 diabetes who use insulin or certain diabetes medicines), headache, fatigue, and dizziness.

Like Saxenda, Wegovy affects stomach emptying. Ask your healthcare provider when you should time any oral medications.

Wegovy has the same black box warning as Mounjaro and Saxenda regarding thyroid tumors.  

Natural alternatives to phentermine

Many patients ask about natural alternatives to phentermine. The natural alternative aisle is filled with diet pills and weight loss supplements touting weight loss benefits and money-back guarantees. Ingredients like green coffee bean extract, green tea extract, guarana, vitamin b6, and cayenne pepper may sound harmless. However, long-term studies of natural supplements conclude that even though they are made with natural ingredients, these supplements are not likely to contribute to significant weight loss—and in some cases, may harm the patient. Be cautious when supplement labels claim to boost energy, boost metabolism, and increase fat burning and energy levels to stop weight gain and fat production. These assertions are likely unfounded and do not mean that they are natural phentermine alternatives or phentermine substitutes. Don’t be fooled. Approved over-the-counter phentermine alternatives and phentermine alternative supplements do not exist.

Also, supplements are not held to the same standards as high-quality prescription medications. The Dietary Supplement Health and Education Act (DSHEA) assigns responsibility to dietary supplement companies to ensure safety standards. The FDA does not have the authority to approve supplements for safety and efficacy before they are sold to the public. If you are considering taking a supplement to help with weight loss, consult your healthcare provider. However, prescription weight loss medications are not studied in combination with supplements, so you should not use a supplement in combination with a prescription weight loss medication—unless advised by your healthcare professional. 

Consult your healthcare provider about dietary changes and exercise. A registered dietician can be an excellent resource on your weight loss journey in helping you devise a personalized eating plan that considers your nutritional needs, calorie intake, medical conditions, and lifestyle. Diets are not a one-size-fits-all approach. The best eating plan is one that is healthy, with a variety of nutritious foods, and is something you can stick to for the long term. 

Regarding exercise, adults should aim for at least 150 minutes of moderate-intensity activity per week to help decrease body fat, plus two days of muscle-strengthening activity to help build and maintain muscle mass. One way to attain the 150 minutes is to walk for 30 minutes a day, 5 days a week. A gym is not necessary—you can walk outside or choose from thousands of free YouTube videos—there are even free indoor walking videos online. Just check with your healthcare provider first, if there are any limitations on physical activity, before selecting an exercise plan. 

How to switch to a phentermine alternative

When considering a switch to a phentermine alternative:

  • Check your formulary, or ask your healthcare provider to check your formulary, to see which phentermine alternatives your health insurance plan covers. You can also search the SingleCare website or mobile app for free coupons. SingleCare customers can save up to 80% on prescription prices—what’s more, you can use SingleCare savings every time you fill your prescription.
  • Consult your healthcare provider. Your healthcare provider is the only one who can determine which medication is best for you, considering your medical and family history, medical conditions, and medications you take that may potentially interact with weight-loss medications. You can also talk about dietary changes and exercise and ask for a referral to a registered dietician.
  • Once the new prescription is sent to the pharmacy, speak with your pharmacist. Review dosing instructions and potential side effects, and ask any questions you may have. If you get an injectable drug, be sure you understand how and when to use it. 
  • When at home, read the prescription label, patient information leaflets, and/or medication guides. If anything concerns you or if you have questions, consult your healthcare provider or pharmacist. 

Modern drugs for the treatment of obesity · “Siberian fiber”

The purpose of the use of pharmacological drugs for the regulation of body weight is not only to reduce the volume of fat mass, but also to reduce the risk of developing metabolic diseases – cardiovascular pathology and diabetes mellitus.

These drugs interfere with the fundamental processes in the human body – the homeostatic mechanisms of weight regulation, by altering appetite, metabolism or absorption of calories. The effect of such funds is not unlimited (and here you should not believe advertising promises) – as a rule, weight loss when taking them does not exceed 10%. Usually, a threshold of at least 5% is considered a clinically significant effect. . In the event that this result cannot be achieved, it is necessary to try a different treatment tactic.

Surprisingly, there are not so many modern, effective and safe drugs for long-term (up to a year) treatment of obesity. We will talk about them without touching on drugs intended for short-term use, the toxicity of which is much higher, and the effectiveness is lower.

One of the latest reviews on this topic was written by the staff of the Department of Pharmacology of the Vardman Mahavir Medical College, New Delhi, India. For example, in the United States, where the problem of treating obesity is extremely acute, the Food and Drug Administration (FDA) officially approved only four pharmaceuticals for use: orlistat (orlistat), lorcaserin (lorcaserin), phentermine /topiramate (phentermine/topiramate) and naltrexone/bupropion (naltrexone/bupropion). Orlistat was the first to be registered and allowed (at 1999), then lorcaserin and phentermine/topiramate (in 2012) and lastly naltrexone/bupropion (already in 2014). Several more new agents are currently in clinical trials (Eur J Intern Med. 2015).

Orlistat (better known as Xenical in Russia) reduces intestinal fat absorption by inhibiting the activity of the pancreatic lipase enzyme involved in the breakdown (hydrolysis) and absorption of fats (triglycerides). Its disadvantage is steotorrhea, i.e. copious excretion of fat with feces, difficult to regulate stool. To prevent these unpleasant side effects when using Orlistat, a low-fat diet is recommended.

Lorcaserin (known under the brand name Belviq) is a 5-HT2C serotonin receptor antagonist that reduces hunger and makes the patient feel full with smaller amounts of food.

Phentermine/topiramate ER (brand name “Qsymia”) – a combination of two drugs. Phentermine is well known as an appetite suppressant, but its use is far from safe. In Russia, it is included in List II of the list of narcotic drugs, psychotropic substances and their precursors subject to control! Topiramate (brand name Topamax) was originally used as an antiepileptic drug and is now used for short-term weight loss in type 2 diabetes.

Naltrexone/bupropion combination (brand name Contrave). Bupropion is known as an antidepressant used to treat nicotine addiction. Naltrexone is an opioid receptor antagonist used to treat drug and alcohol addiction. The drug has been approved in the USA since 2014, but not in Russia and EU countries.

Rimonabant, on the other hand, is allowed in Europe, but banned in the US and Canada for safety reasons. It is a CB1 cannabinoid receptor antagonist. It selectively acts on receptors in the brain and peripheral organs, reduces lipogenesis (fat formation) in peripheral organs, which not only causes weight loss, but also changes the metabolic effect of obesity on the body. Complications – severe depression and a predisposition to neurodegenerative diseases, such as Alzheimer’s disease, amylotrophic sclerosis.

Among the previously used and very popular drugs can be called Sibutramine (Sibutramine). This drug acts on the brain and inhibits the deactivation of neurotransmitters (bioactive chemicals through which nerve impulses are transmitted), thereby reducing appetite. It was banned in the US and Canada and other countries in October 2010 due to identified side effects in relation to the cardiovascular and central nervous systems; officially registered deaths. Unfortunately, unscrupulous manufacturers still include Sibutramine in dietary supplements and unlicensed weight loss products (for example, the Chinese product Lida by Dali, etc.), and at an extremely high dosage.

Another drug often prescribed to obese patients is Metformin, which is primarily intended for the treatment of diabetes. Metformin activates the enzyme cyclo-adenosine monophosphate (cyclo-AMP, cAMP), an activated protein kinase, and inhibits gluconeogenesis (formation of glucose) in the liver. Side effects – acidosis due to excess formation of lactic acid, dysfunction of the gastrointestinal tract.

Pemmington Biomedical Research Center, Louisiana State University, Baton Rouge, USA classifies weight management agents into two groups: those intended directly for the treatment of obesity, or those intended to affect body weight in those who have complications from obesity and who require additional treatment chronic metabolic diseases. Among the drugs of the first group, intended for long-term use, are orlistat, which gives a weight loss of 5-8 kg, but has limitations due to the development of side effects from the gastrointestinal tract; lorcaserin, a serotonin-2C agonist that can reduce weight by 4-7 kg, but also has side effects; and a combination of phentermine with topiramate, which reduces weight by 8-10 kg, contraindicated in pregnant women. The authors also believe that if there is no effect (less than 3% weight loss) within 3 months, the therapy tactics should be reconsidered. Among the drugs designed for short use, phentermine is distinguished primarily. And among drugs intended for use in people burdened with diseases such as diabetes, mental disorders, depression, the selection of adequate drugs is more difficult (Ann N Y Acad Sci. 2014).

In 2014, JAMA published a very lengthy (13 page) review of the pharmacotherapy of obesity by members of the Division of Digestive and Nutritional Diseases at the National Institute of Diabetes, National Institutes of Health. The authors analyzed the meta-analyses, reviews and results of clinical trials presented in the PubMed database (a total of 564 papers) that lasted at least 1 year and included at least 50 people per group. Weight reduction compared to placebo for 1 year ranged from 3% for orlistat and lorcaserin to 9%.% for the highest dose of phentermine/topiramate (15/92 mg). The proportion of patients with a clinically measurable effect (loss of at least 5% of body weight) was 37-47% for lorcaserin and 67-70% for phentermine/topiramate at the highest dose. All three drugs significantly reduced cardiometabolic risk factors compared with placebo, but none of them reduced morbidity and mortality from cardiovascular disease. There are data only on short-term use of such drugs, but not on their long-term use. If successful, patients lose 7-10% of body weight per year, but if this figure is below 5%, then there is no point in such therapy.

Whether or not to use such drugs in an obese patient is usually decided by the doctor; Xenical (orlistat) is the only over-the-counter drug. And this is absolutely correct, since these drugs interfere with the finest mechanisms of metabolism regulation. Treatment must be controlled – the risk of developing severe complications from the cardiovascular system, kidneys, liver, and also the psyche is very high.

Adipex is a drug that helps reduce a person’s appetite, which in turn makes a person. It is an anorectic that is used to metabolize body fat.

This medicine should not be taken by people over the age of sixteen, pregnant adults, or those with hypertension or other heart problems. It uses phentermine as the active ingredient but also contains some other inactive ingredients.

Phentermine is a drug that acts on the hypothalamus, which in turn helps suppress a person’s appetite. This is the common name for diet pills that are produced by different pharmaceutical companies in different dosages. 9Phentermine Available as Adipex itself.
