Can phentermine cause hair loss? Phentermine is a stimulant medication prescribed for weight loss. Its active ingredient stimulates the central nervous system, increasing heart rate and blood pressure. One potential side effect is hair loss, although it is relatively uncommon.
Phentermine is often used in combination with other weight-loss medications or lifestyle changes. It can be an effective tool for short-term weight loss, but long-term use is not recommended. Hair loss is a rare but potential side effect, and it is important to be aware of this possibility before starting treatment.
