How to Take Phentermine

Phentermine is an oral medication available as capsules, tablets, and orally disintegrating tablets. It is typically taken once daily in the morning, either before breakfast or shortly after breakfast. Some versions may be taken multiple times a day before meals.

To help prevent insomnia, avoid taking this medication late in the day.

Administration Instructions

Standard Tablets and Capsules: Swallow the medication as directed by your healthcare provider.

Orally Disintegrating Tablets: Use dry hands to handle the tablet. Place it on the tongue and allow it to dissolve before swallowing. This can be done with or without water.

Phentermine is meant for short-term use only, generally for a few weeks. It is most effective when combined with a healthy diet and regular physical activity.

Missed Dose

If you miss a dose, take it as soon as you remember. However, if it is late in the day, skip the missed dose and take the next one at your regular time the following morning. Do not take extra medication to make up for a missed dose.

Question 9

Is Phentermine safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Phentermine should not be used during pregnancy. Weight loss offers no potential benefit to a pregnant person and may result in fetal harm. Medical guidelines typically recommend a minimum weight gain for all pregnant individuals, including those who are already overweight or obese, to support the development of the fetus.

If you are pregnant or planning to become pregnant, discuss weight management and nutrition with a healthcare professional. If you discover you are pregnant while taking this medication, it is important to notify your doctor immediately.

Breastfeeding

It is not known if phentermine passes into human breast milk. Because many drugs are excreted in milk and there is a potential for serious adverse reactions in nursing infants, healthcare providers generally recommend either stopping the medication or avoiding breastfeeding while using phentermine.

Consult with a healthcare provider to discuss the risks and benefits of using this medication if you are planning to breastfeed or are currently nursing.

Question 11

What is the FDA approval status of Phentermine?

Accepted Answer

FDA Approval and Indications

Phentermine was first approved by the U.S. Food and Drug Administration (FDA) in 1959. It is currently approved for short-term use, typically defined as up to 12 weeks, as an adjunct to a regimen of weight reduction based on exercise, behavioral modification, and caloric restriction.

The medication is indicated for patients with an initial body mass index (BMI) of:

30 kg/m2 or greater (obese)

27 kg/m2 or greater (overweight) in the presence of other risk factors, such as controlled hypertension, diabetes, or hyperlipidemia.

Controlled Substance Status

Phentermine is classified by the Drug Enforcement Administration (DEA) as a Schedule IV controlled substance . This classification is due to its chemical similarity to amphetamines, which carries a risk for misuse, abuse, and physical or psychological dependence. Because of these risks, its use is strictly regulated and limited to short durations.

Regulatory History and Safety

In the late 1990s, phentermine was frequently prescribed in combination with fenfluramine or dexfenfluramine, a combination commonly known as Fen-Phen. While the FDA requested the withdrawal of fenfluramine and dexfenfluramine from the market in 1997 due to reports of heart valve disease, phentermine remained FDA-approved and available for use as a standalone treatment.

Current regulatory labeling includes warnings regarding the risk of primary pulmonary hypertension and valvular heart disease, although these were more strongly associated with the combination therapies. The FDA requires that phentermine be used only for short-term management and not in combination with other weight-loss drugs unless specifically approved for such use.

Question 12

What should I know about Phentermine and weight loss?

Accepted Answer

Role in Weight Management

Phentermine is an appetite suppressant that belongs to a class of medications called anorexiants. It works by stimulating the central nervous system to decrease appetite. Because it is chemically related to amphetamines, it is classified as a controlled substance.

Who It Is For

Healthcare providers typically prescribe phentermine for adults who have significant health risks due to their weight. This includes:

People with a body mass index (BMI) of 30 or higher (obesity).

People with a BMI of 27 or higher (overweight) who also have weight-related medical conditions such as high blood pressure, diabetes, or high cholesterol.

Short-Term Use

Phentermine is approved only for short-term use, usually up to 12 weeks. It is not intended for long-term weight maintenance because its effects may wear off after several weeks as the body builds a tolerance. Additionally, because of the potential for misuse or dependency, long-term use is generally avoided.

Maximizing Effectiveness

Weight loss results are most effective when phentermine is combined with lifestyle modifications. These include:

Following a low-calorie or reduced-calorie diet.

Engaging in regular physical activity.

Implementing behavioral changes to support healthy habits.

If significant weight loss is not achieved within the first few weeks of treatment, a healthcare provider may decide to discontinue the medication, as increasing the dose does not usually improve results and may increase the risk of side effects.
