TRAMADOL (UltramÃ‚Â®) is an analgesic that can relieve moderate to moderately severe pain following surgery such as cesarean section, hysterectomy, hip replacement or other bone surgery, and dental surgery. This drug also helps relieve chronic pain associated with cancer, nerve pain, or low-back pain.
The pill you described is Tramadol, 50 mg. and distrubuted by Barr. Although I have not seen this particular pharmaceutical's listing here, you can find out more about tramadol at www.drugs.com/tramadol.html.
Hope this helps.
