This medication is an appetite suppressant and belongs to a class of drugs called sympathomimetic amines.

In such cases, withdrawal symptoms (such as depression, severe tiredness) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions right away.

Faq for PHENDIMETRAZINE - ORAL

Phendimetrazine is an oral medication used for weight loss. It belongs to a class of drugs known as sympathomimetic amines, which help suppress appetite and increase metabolism.

Phendimetrazine should be taken exactly as prescribed by your healthcare provider. Typically, it is taken once a day, 30-60 minutes before a meal. Avoid taking it late in the day as it may cause insomnia.

Common side effects of Phendimetrazine include dry mouth, increased heart rate, restlessness, nervousness, and constipation. Inform your doctor if these side effects persist or worsen.

Phendimetrazine has the potential to be habit-forming. It should only be used for a short period of time (few weeks) as part of a comprehensive weight loss program under the guidance of a healthcare professional.

Phendimetrazine should not be used if you have a history of heart disease, uncontrolled high blood pressure, hyperthyroidism, glaucoma, or a history of drug abuse. It should also be avoided during pregnancy or breastfeeding.

Phendimetrazine may interact with other medications, such as MAO inhibitors, antidepressants, antihistamines, and certain diabetes drugs. It is important to inform your doctor about all the medications you are taking to avoid any potential interactions.

If you miss a dose, take it as soon as you remember. However, if it is close to your next scheduled dose, skip the missed dose and resume your regular dosing schedule. Do not double the dose to make up for a missed one.

Phendimetrazine is usually prescribed for a few weeks to help with weight loss. Prolonged use beyond that timeframe is generally not recommended due to the risk of developing tolerance and dependence.

Phendimetrazine should only be used by individuals who are clinically overweight or obese and at risk for weight-related health problems. It is not intended for cosmetic weight loss or use by individuals looking to shed a few pounds for aesthetic reasons.
