Adipex-P (phentermine) is a prescription appetite suppressant used short-term to support weight-loss efforts in people with obesity. It works by affecting the central nervous system to reduce hunger, but it can also cause side effects such as increased heart rate, insomnia, and dependence if not used properly. Because of these risks, Adipex should only be taken under the supervision of a licensed healthcare professional. Safe, legal access requires a valid prescription and appropriate medical monitoring.
