Tramadol is used only when other pain treatments such as non-opioid medicines (for example, acetaminophen, ibuprofen) do not work or you cannot tolerate them. Never give anyone else your tramadol as they could die from taking it. Selling or giving away tramadol is against the law. Tramadol is classified by the DEA as a C-IV controlled substance.
