A medication is the active ingredient in Aspadol 150 Tapentadol. Adults with moderate to severe pain are treated with this centrally-acting analgesic. It attaches itself to specific brain and spinal cord receptors to decrease the sense of pain. It is only recommended for brief periods of use, typically a few days to a few weeks, as prolonged use has the potential to cause dependency, tolerance, and addiction. As with any medication, take it exactly as prescribed by your doctor, and before starting treatment, ask them about any potential risks or adverse effects.
