My Dr. prescribed first phendimetrazine 35mg for weight loss. Since this did not work that well, he perscribed Diethylpropion 25mg for two weeks. He told me to take diethylpropion the same way as phendimetrazine, 1 in the morning, 2 pills an hour before lunch and 2 pills an hour before dinner. Now, I have read side effects and suggested amount to take on the diethylpropion and I am worry, I may be taking too much of this pill. Can someone tell me if I should be concern on the amount I am taking? and does anyone know if diethylpropion is better than phendimetrazine?.Thanks
