Can phentermine cause permanent damage?

Phentermine may increase thyroid activity. This can raise thyroid levels even higher. This can cause permanent damage to vision. The possible link between phentermine and heart failure is due to rare reports of valvular heart disease in people who took the medication.

The medication can also cause pulmonary hypertension, which can be fatal. Phentermine is a sympathomimetic amine, like amphetamine, which is one of the most commonly prescribed medications for weight loss. Although the exact mechanism of phentermine that causes psychosis is not yet clear, numerous reports have already demonstrated that phentermine can induce psychosis. Psychotic symptoms usually resolve once medications are stopped.

Rather, we present the case of a 25-year-old Asian patient who repeatedly developed psychotic symptoms after phentermine administration. This case suggests that phentermine may cause psychotic episodes repeatedly, resulting in chronic occupational and social deterioration. Therefore, a precautionary measure is urgently needed, such as government regulations for prescribing physicians and education for patients taking phentermine. Sometimes, instead of prescribing phentermine alone, doctors prescribe a medication that combines phentermine with topiramate.

Although the exact mechanism of psychosis caused by phentermine is not yet clear, numerous reports have already shown that the psychosis was induced by phentermine.
