The topiramate is taken for migraines and prozac for depression. Recently started taking 37.5 mg of phentermine to lose weight under doctor's care. Will only be taking for 2 month intervals but worried about side effects or long term damage I might be doing to body. Is this safe? Phentermine is already working to help take the weight off and I see they are marketing a pill that is combination of phen and topiramate? However I worry that the prozac and phen is a dangerous combination?
