It is primarily recommended for people suffering from obesity, rather than those who are a few pounds over weight or those wanting a quick fix to their weight loss goals.

For those who have a significant amount of weight to lose, the phentermine side effects may be well worth the risk, especially since the health risks associated with obesity are so high and the health risks so severe as well. Consumers should consult their healthcare professionals, inform them of their health history, any pre-existing conditions not formerly discussed, and provide a comprehensive list of all medications regularly taken, including vitamins and natural or herbal healthcare medications or supplements. Your doctor can then determine if using phentermine is the best course of treatment and safe for you to use.Don’t just rely on a weight loss center for a recommendation or a prescription.
