Co-proxamol is an analgesic medication, commonly referred to as a painkiller, that combines the effects of paracetamol and the mild opioid analgesic dextropropoxyphene. It is prescribed for the relief of mild to moderate pain that has not responded adequately to paracetamol or other non-opioid analgesics alone. Common side effects of co-proxamol include dizziness, drowsiness, constipation, and nausea. Prolonged use of the drug may lead to dependence and habit formation.
