Phentermine is classified as a Schedule IV controlled substance by the US DEA due to its potential for abuse and dependence. It is intended for short-term use, typically 12 weeks or less, and is not recommended for long-term weight loss maintenance.
Common side effects of phentermine use can include dry mouth, nausea, constipation, headaches, and difficulty sleeping. More serious side effects can include high blood pressure, heart palpitations, and trouble breathing. Phentermine should only be taken as prescribed by a healthcare professional and patients should never take more than their prescribed dose or use the drug recreationally.
Phentermine is a prescription weight loss medication that is used to help patients lose weight in conjunction with diet and exercise. It is a sympathomimetic amine, which means it works by stimulating the release of certain chemicals in the brain that help suppress appetite and increase energy expenditure.
