Phentermine hydrochloride.

Why clinicians prescribe it
Works quickly
Appetite suppression is usually noticeable within the first few days.
Low cost
The least expensive prescription weight option we offer.
Useful as a bridge
Occasionally used while insurance is being sorted out for another treatment.
Common questions
The approval is for short-term use, tolerance develops, and it is a controlled substance. Longer use happens in some practices but requires a specific clinical rationale and close monitoring.
Important safety information
A controlled substance. Not for anyone with cardiovascular disease, uncontrolled hypertension, hyperthyroidism, glaucoma, a history of substance misuse, or during pregnancy. Insomnia, dry mouth, and raised heart rate are common. Blood pressure is monitored.
