I am trying to find a doctor that will prescribe the prescription adipex. I need to know what the doctor specialize in. In order to find a doctor I need to know the field that such a doctor practice.

Adipex (http://www.drugs.com/adipex.html)

I would think maybe a nutritionist? Or any dr that specializes in weight loss.

Have you talked with your regular dr about taking this drug yet?

A regular GP ( assuming US) can do it, as can any doctor licensed to prescribe drugs. But finding one that will
1. believe you need it
2. believes this is the best drug

Is another issue.
