GENERAL INFORMATION
Co-proxamol is the generic name for a Combination of the non-opioid analgesic drug paracetamol and a mild opioid analgesic, dextropropoxyphene. Co-proxamol is used for the relief of mild to moderate pain that has not responded to
paracetamol or other non-opioid analgesics alone.
Because the drug contains an opioid, it can cause a variety of side effects that are common to drugs of that group: dizziness, mild euphoria, nausea, and constipation. Co-proxamol may also be habit-forming if taken regularly for an extended period. Overdose with co-proxamol is dangerous because dextropropoxyphene may interfere with breathing
if it is taken in excess, and overdose of paracetamol may cause irreversible damage to the liver and kidneys.
