Aspadol 200 mg contains Tapentadol, a strong painkiller used for moderate to severe pain. While effective, it may cause side effects like dizziness, nausea, vomiting, constipation, drowsiness, and dry mouth. These are common but usually mild. Serious side effects include breathing difficulties, confusion, seizures, addiction, or allergic reactions (rash, swelling). Long-term use raises dependency risks. Avoid alcohol and driving, as it enhances drowsiness. Always take Aspadol as prescribed—never exceed the dose. Consult a doctor if side effects worsen. Pregnant women, seniors, and those with liver/kidney issues should use it cautiously. Stay informed and use responsibly!
