Phentermine / topiramate
"I have lost 50 lbs. since May, 2016....I do not take the combined drug.  Some people are complaining about the cost has anyone ever looked into Good Rx coupons? Even the Good Rx is high - close to or over $200 for a month but by taking 2 separate pills I only pay about $20 per month so why take the comb. pill... I really don't understand.  Is it better?"
