Phendimetrazine is used as an appetite suppressant. It is used in conjunction with an overall diet plan to reduce weight.
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 this medication as prescribed. Do not take it more often or longer than directed. It 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.
Side effects that may occur while taking Phendimetrazine include blurred vision, dizziness, dry mouth, sleeplessness, irritability, stomach upset or constipation may occur the first few days as your body adjusts to Phendimetrazine. 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 overactive 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.
If you take too much:
If overdose is suspected, contact your local poison control center or emergency room immediately. Symptoms of overdose may include restlessness, tremor, rapid breathing, confusion, nausea, vomiting, diarrhea, and stomach cramps.
If you miss a dose, do not double the next dose. Instead, skip the missed dose and resume your usual dosing schedule.
Store at room temperature away from sunlight and moisture. Keep this and all medications out of the reach of children.
