PHENTERMINE HYDROCHLORIDE AND TOPIRAMATE (phentermine hydrochloride) · Teva

Cytochrome P450 3A4 Inducers
Metabolic Approved 2024-06-25

Phentermine hydrochloride helps patients with weight reduction when used for a short period of time alongside exercise, behavioral changes, and a low-calorie diet. It treats exogenous obesity in individuals with a body mass index (BMI) of 30 or higher, or those with a BMI of 27 or higher who also have risk factors like diabetes, high blood pressure, or high cholesterol. Because its effectiveness is limited to a few weeks, it is used as a temporary addition to a broader weight management plan.
