Aspadol 100 mg contains Tapentadol, a strong pain reliever used to treat moderate to severe acute pain. It works by altering how the brain and nervous system respond to pain. This medication is often prescribed after surgeries or injuries when other painkillers are ineffective. Aspadol should be used under medical supervision due to its potential for dependence and side effects like dizziness, nausea, and drowsiness. Avoid alcohol while taking this medication.
