Nausea is a common side effect of Aspadol (Tapentadol) 150mg, but it can be managed effectively. Start by taking the medication with food or milk to reduce stomach irritation. Staying hydrated and eating small, frequent meals can also help. If nausea persists, ask your doctor about anti-nausea medications like ondansetron or domperidone. Avoid sudden movements and rest in a comfortable position to minimize dizziness. Always follow your prescribed dosage and never crush or break the tablet, as it can increase side effects. If nausea becomes severe or persistent, consult your healthcare provider for alternative pain management options.
