Phendimetrazine is a sympathomimetic amine, which is similar to an amphetamine. It is also known as an "anorectic" or "anorexigenic" drug. Phendimetrazine stimulates the central nervous system (nerves and brain), which increases your heart rate and blood pressure and decreases your appetite. Phendimetrazine is used as a short-term supplement to diet and exercise in the treatment of obesity. Phendimetrazine may also be used for purposes other than those listed in this medication guide.
Take phendimetrazine exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you. Take each dose with a full glass of water. Phendimetrazine is usually taken once a day (sustained release formula) or two to three times daily (immediate-release formula) before meals on an empty stomach. Do not take phendimetrazine in the evening because it may cause insomnia. Do not crush, chew, or open any "once-daily" phendimetrazine tablets or capsules. Swallow them whole. Never take more of this medication than is prescribed for you. Too much phendimetrazine could be very dangerous to your health. Store phendimetrazine at room temperature away from moisture and heat.
