Phendimetrazine is a sympathomimetic amine, which is similar to an amphetamine. Phendimetrazine is also known as an "anorectic" or "anorexigenic" medication. This medication is used as an appetite suppressant. It is used in conjunction with an overall diet plan to reduce weight.
Phendimetrazine stimulates the central nervous system (nerves and brain), which increases your heart rate and blood pressure and decreases your appetite. Phendimetrazine is recommended by physicians as a short-term supplement to diet and exercise in the treatment of obesity.
Phendimetrazine is best taken on an empty stomach one hour before meals. Sustained-release or long acting products must be swallowed whole. Crushing or chewing them will destroy the long action and may cause increased side effects. Because this medication may cause sleeplessness, avoid taking a dose late in the day. Take Phendimetrazine as prescribed. Do not take it more often or longer than directed.
If you miss a dose, do not double the next dose. Instead, skip the missed dose and resume your usual dosing schedule.
If overdose is suspected, contact your local poison control center or emergency room immediately. Symptoms of overdose may include restlessness, fever, fast breathing, dizziness, confusion, hallucinations, panic or paranoid, drowsiness, convulsions, unconsciousness, unusually fast or slow heart beat, headache, nausea/vomiting, diarrhea, stomach pain, pale or flushing, chest pain, sweating, muscle weakness, agitation, large pupils, or delusions.
- Phendimetrazine must be stored at room temperature away from heat and light.
- Do NOT store Phendimetrazine in the bathroom, near the kitchen sink, or in other damp places. Heat or moisture may cause the medicine to break down.
- Do NOT keep outdated medicine past the expiry date.
- Phendimetrazine should be kept out of children's reach.
Duration of usage:
Phendimetrazine is usually taken for 8 to 12 weeks. Use in combination with other appetite suppressant medicine is generally not recommended. Consult your doctor before such use.
Blurred vision, dizziness, dry mouth, sleeplessness, irritability, stomach upset or constipation may occur the first few days as your body adjusts to the medication. If these effects persist or become bothersome, inform your doctor. Notify your doctor if you experience chest pain, nervousness, pounding heart, difficulty urinating, mood changes, breathing difficulties or swelling while taking this medication. If this medication makes you dizzy or lightheaded, avoid driving or engaging in activities requiring alertness.
Tell your doctor your complete medical history especially if you have high blood pressure, an over-active thyroid, glaucoma, diabetes or emotional problems. Consult with your doctor if you think you are pregnant or before breast-feeding. This medication can be habit forming and must be used with caution. Alcohol can increase unwanted side effects of dizziness. Limit alcohol use. This drug is not recommended for use in children. Consult your doctor or pharmacist for further information.
Inform your doctor about all the medicines you use, (prescription and nonprescription) especially if you take high blood pressure medicine or MAO inhibitors (e.g., furazolidone, phenelzine, selegiline, tranylcypromine) or any other weight loss medicine. Avoid "stimulant" drugs that may increase your heart rate such as decongestants or caffeine. Decongestants are commonly found in over-the-counter cough and cold medicine.
Appetite suppressants are not a substitute for proper diet. For maximum effects, this must be used in conjunction with a diet and exercise program. Do not share this medication with others.
