The particular trials revealed that about thirty percent of Fenfluramine and Dexfenfluramine users had valvular Phentermine 37.5 abnormalities, what exceeded expectations greatly. These findings mainly demonstrated that valvular incorrectnesses prevalently develop in patients who took drugs containing dexfenfluramine and fenfluramine for more than 6 months. As a result Fenfluramine and Dexfenfluramine were withdrawn by FDA September, 1997. Notice, that FDA failed to demand to withdraw Phentermine.
