Bontril is used as an appetite suppressant. It is used in conjunction with an overall diet plan to reduce weight.
How does Bontril work?
Take on an empty stomach, once daily, 30-60 minutes before breakfast. 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.
Bontril Side Effects
Blurred vision, dizziness, dry mouth, sleeplessness, irritability, stomach upset or constipation may occur the first few days as your body adjusts to Bontril. 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.
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.
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.
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.
Bontril Missed Dosage
If you miss a dose of Bontril, do not double the next dose. Instead, skip the missed dose and resume your usual dosing schedule.
Seek emergency medical attention. Symptoms of a Bontril overdose include restlessness, tremor, rapid breathing, confusion, hallucinations, panic, aggressiveness, nausea, vomiting, diarrhea, an irregular heartbeat, and seizures.
