Otherwise known as Phendimetrazine, Bontril is an appetite suppressant, used as a short term supplement to diet, exercise and behavioural therapy in a monitored weight loss program. It increases your metabolism and reduces appetite.
Bontril works by stimulating your central nervous system and increasing your blood pressure and heart rate. Similar to an amphetamine, it affects certain neurotransmitters to decrease your appetite. It belongs to a class of drugs called anorexiants, with the ability to reduce appetite.
How do you take Bontril?
Doctors usually recommend that you take Bontril on an empty stomach, preferably an hour before meals. The pills must be taken whole – crushing or chewing can increase side effects and reduce Bontril’s long-lasting action. Also remember to drink a full glass of water with the pill.
Only take as much as your doctor prescribes as there is a risk of overdose. Bontril should also not be taken in conjunction with other diet pills. If you miss a dose then do not double-dose the next day. A dose taken late in the day may also cause insomnia.
Who should not take Bontril?
You should consult your doctor if you have any of the following conditions:
Heart disease, Arteriosclerosis, Glaucoma, Thyroid problems, Anxiety, a seizure disorder such as epilepsy, Diabetes, a history of drug/alcohol abuse.
Patients who are pregnant or breastfeeding should avoid Bontril, as well as those who have taken a monoamine oxidase inhibitor in the last 2 weeks. Always check with your doctor first.
