PHENDIMETRAZINE - ORAL
(FEN-dye-meh-TRA-zeen)
COMMON BRAND NAME(S): Bontril PDM, Plegine
USES: Phendimetrazine is used with a doctor-approved exercise, behavior change, and reduced-calorie diet program to help you lose weight. It is used by certain overweight people, such as those who are obese or have weight-related medical problems. Losing weight and keeping it off can lessen the many health risks that come with obesity, including heart disease, diabetes, high blood pressure, and a shorter life.It is not known how this medication helps people to lose weight. It may work by decreasing your appetite, increasing the amount of energy used by your body, or by affecting certain parts of the brain. This medication is an appetite suppressant and belongs to a class of drugs called sympathomimetic amines.
HOW TO USE: Take the immediate-release form of this medication by mouth as directed by your doctor, usually 2 to 3 times a day (1 hour before meals). Taking this medication late in the day may cause trouble sleeping (insomnia).The sustained-release form of phendimetrazine is usually taken once a day 30 - 60 minutes before the morning meal.

Your doctor will adjust the dose to find the best dose for you. Use this medication regularly and exactly as prescribed in order to get the most benefit from it. To help you remember, take it at the same time(s) each day.Phendimetrazine is usually taken for only a few weeks at a time.

To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used phendimetrazine for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.Though it helps many people, this medication may sometimes cause addiction.
