What should I discuss with my healthcare provider before taking phendimetrazine (Adipost, Bontril PDM, Bontril Slow Release, Melfiat)?
Do not use phendimetrazine if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.
You should not use this medication if you are allergic to phendimetrazine, or if you have:
To make sure you can safely take phendimetrazine, tell your doctor if you have any of these other conditions:
It is not known whether phendimetrazine will harm an unborn baby. Do not take phendimetrazine without first talking to your doctor if you are pregnant.
It is also not known whether phendimetrazine passes into breast milk. Do not take phendimetrazine without first talking to your doctor if you are breast-feeding a baby.
How should I take phendimetrazine (Adipost, Bontril PDM, Bontril Slow Release, Melfiat)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Phendimetrazine should be taken only for a short time, such as a few weeks.
Phendimetrazine is usually taken once daily. Follow your doctor's instructions.
Take phendimetrazine on an empty stomach, 30 to 60 minutes before your morning meal.
Do not crush, chew, break, or open the extended-release capsule. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.
You should lose at least 4 pounds during the first 4 weeks of taking phendimetrazine and eating a low calorie diet. Tell your doctor if you do not lose at least 4 pounds after taking the medication for 4 weeks.
Do not stop using phendimetrazine suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to avoid withdrawal symptoms when you stop using phendimetrazine.
Never take more of this medication than is prescribed for you. Too much phendimetrazine could be very dangerous to your health. Talk with your doctor if you have increased hunger or if you otherwise think the medication is not working properly. Taking more of this medication will not make it more effective and can cause serious, life-threatening side effects.
Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
