Bontril stimulates the central nervous system. When the nervous system is stimulated, it has these effects on the body:

• Heart beats faster
• Blood pressure rises
• Appetite is decreased

While the effects of Bontril do wear off over time, this product can greatly aid in getting weight loss going during those first few tough weeks. Most people take it for 8 to 12 weeks.

Bontril belongs to a group of medications called sympathomimetic amines, which are similar to amphetamines.
