Stopping Phentermine

How to stop taking phentermine

If you have been taking phentermine in large doses or for a long period of time, do NOT stop taking it without first consulting your doctor. S/he may want you to gradually reduce the amount you are taking before stopping completely. This will help prevent withdrawal side effects.

After you stop taking phentermine, your body may need time to adjust. The length of time this takes depends on the amount of medicine you were using and how long you used it. During this time, speak to your doctor if you notice any side effects (as noted above in Physical or mental dependence on phentermine).
