What are the serious long term side effects of duromine?

Duromine. Allow me my soapbox moment: always ask your prescribing doctor & dispensing pharmacist about potential side effects vs desired benefits. Duromine is a global brand (http://www.drugs.com/international/duromine.html) of phentermine, a stimulant similar to methamphetamine, which is used as appetite suppressant.
