If you wait until the pain has worsened, the medication may not work as well.If you have ongoing pain (such as due to arthritis), your doctor may direct you to also take long-acting narcotic medications. Other non-narcotic pain relievers (such asacetaminophen, ibuprofen) may also be prescribed with this medication. Ask your doctor or pharmacist if you have any questions about using tramadol safely with other drugs.This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as restlessness, watering eyes, runny nose, nausea, sweating, muscle aches) may occur if you suddenly stop using this medication.

Tramadol

Tramadol hydrochloride (trademarked as Conzip, Ryzolt, Ultracet, Ultram in the USA, Ralivia and Zytram XL in Canada) is a centrally-acting synthetic analgesic used to treat moderate to moderately-severe pain. The drug has a wide range of applications, including treatment of rheumatoid arthritis, restless legs syndrome and fibromyalgia. It was launched and marketed as Tramal by the German pharmaceutical company Grünenthal GmbH in 1977.

Tramadol is a very weak μ-opioid receptor agonist, induces serotonin release, and inhibits the reuptake of norepinephrine.Tramadol is converted to O-desmethyltramadol, a significantly more potent μ-opioid agonist. The opioid agonistic effect of tramadol and its major metabolite(s) is almost exclusively mediated by such μ-opioid receptors. This further distinguishes tramadol from opioids in general (including morphine), which do not possess tramadol's degree of receptor subtype selectivity and which are much stronger opiate-receptor agonists. Similarly, the habituating properties of tramadol (such as they are) are arguably mainly due to μ-opioid agonism with contributions from serotonergic and noradrenergic effects.
