1. Problems with the valves in the heart (valvular heart disease) and high blood pressure in the arteries of the lungs (pulmonary arterial hypertension) have been associated with fenfluramine, the active ingredient in Fintepla.
Your healthcare provider will do a test called an echocardiogram to check your heart and for high blood pressure in the arteries of the lungs before you start treatment, every 6 months during treatment, and one time 3 to 6 months after you take your last dose.

- tiredness or weakness especially with increased activity
- lightheadedness or fainting
- swollen ankles or feet
- chest pain
- sensations of a rapid, fluttering heartbeat (palpitations)

- bluish color to your lips and skin (cyanosis)
Because of the risk of heart valve problems and pulmonary arterial hypertension Fintepla is only available through a restricted program called the Fintepla Risk Evaluation and Mitigation (REMS) Program.

Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.
