How is Phentermine dosed?

It usually is taken as a single daily dose in the morning or three times a day 30 minutes before meals.

How long can you take Phentermine?

The length of treatment depends on how you respond to the medication. While it was originally approved for short term, up to 12 weeks, many weight loss physicians may prescribe it off label for longer duration. In a large scale study that looked at long term dependence on Phentermine, it was found that stopping Phentermine even in patients taking it for decades does not lead to significant withdrawal symptoms. Also, obesity is increasingly being seen as a chronic medical condition just like high blood pressure, and diabetes and therefore, treatment should also be long term.
