Do I need a prescription to buy Phentermine?
Yes. Phentermine is a controlled substance, so it can only be bought with a doctor’s prescription. If you think you are a good candidate and would benefit from using Phentermine, talk to your doctor. Make sure you tell him or her about any medications you are or have been on. If your family has a history of mental illness, depression, anxiety, or any other conditions that fit into that category, tell your doctor.
