Side Effects

Along with its needed effects, a medicine may cause some unwanted effects. Some of these effects, such as high blood pressure, may not have signs or symptoms that you can see or feel. While you are taking sibutramine, your doctor will check your blood pressure and heart rate at regular visits.

Although not all of these side effects may occur, if they do occur they may need medical attention.

Check with your doctor as soon as possible if any of the following side effects occur:

Less common
  • Achiness
