Phentermine

Phentermine, also known as generic Adipex, is a well-established medication that has been successfully used to treat obesity for over 60 years. It was approved by the Federal Drug Administration (FDA) in 1959. Since that time, it has helped millions achieve their health and fitness goals. Phentermine is a Schedule 4 drug.

Phentermine is an appetite suppressant, meaning it decreases the sensation of hunger, cravings, and binge eating. However, it is also a Central Nervous System stimulant, meaning it helps to increase energy level.

Phentermine is also offered combined with topiramate for weight loss (Qsymia). The combined drug is approved for long-term use. 

Common side effects of phentermine include:

· Faster heart rate

· Sleeplessness

· Nervousness

· Constipation

Phentermine is one of the most prescribed weight-loss medicines. But it isn't a good choice for people with heart disease, high blood pressure, an overactive thyroid gland or glaucoma. It also isn't for people who are pregnant, may become pregnant or are breastfeeding.
