Top 10 Prescription Diet Pills That Work Fast

1. Qsymia

Qsymia went on sale in September 2012 by VIVUS, Inc. (NASDAQ:VVUS) and was the first weight-loss drug to be introduced in over a decade. It works mainly as an appetite suppressant and contains two active ingredients: phentermine and topiramate. Phentermine is an ingredient that will be mentioned several times throughout the article and it is responsible for suppressing appetite (it is similar to amphetamine). Topiramate is a medication for treating seizures, but here it works also as an appetite suppressant (apparently it makes food less appealing). However, one of the side effects is that it could cause seizures if the patient suddenly stops taking it.
