What is Ultracet?

Ultracet contains a combination of tramadol and acetaminophen. Tramadol is an pain medicine similar to an opioid (sometimes called, a narcotic)and may be habit-forming. Acetaminophen is a less potent pain reliever that increases the effects of tramadol.

Ultracet is used for the short term (5 days or less) treatment of severe acute pain.

Ultracet is available only under a special program. You must be registered in the program and understand the risks and benefits of this medicine.
