Didrex is the brand name for a generic medication called Benzphetamine. It is similar in action and effects to other medicines in the same class, such as Phentermine, Bontril, Adipex and Ionamin. It should not be used at the same time as any of these medications.

Didrex^® comes in a 50 mg round peach tablet.

How Do I Know What Dose is Right For Me?

To be safe, prescription medication should be taken exactly as directed by your doctor. Your doctor can figure out which dose is right for you based on your BMI and current weight, your medical history, your weight loss goals and other factors.

Most doctors will start you off with a low dose (for example, 25 mg) to see how you react, and then increase the dose later if needed. Remember to talk with your doctor if you're not getting the results from Didrex that you expect.
