Tylenol 3, a brand of co-codamol

Codeine/acetaminophen or co-codamol (BAN) is a compound analgesic consisting of a combination of codeine phosphate and paracetamol (acetaminophen). Co-codamol tablets are used for the relief of mild to moderate pain when paracetamol or NSAIDs such as ibuprofen, aspirin or naproxen alone do not sufficiently relieve a patient's symptoms, or where their use is ill-advised.

Co-codamol is marketed under various brand names in addition to the generic name.

Seven strengths are available:

Combination products containing codeine are available over the counter only in United Kingdom, France, Canada, Australia, New Zealand, Poland, Israel, Latvia, Estonia and Costa Rica and Spain[2]

Other drugs containing paracetamol must be avoided unless otherwise directed by a physician or pharmacist, excessive amounts of paracetamol can lead to serious liver damage, see Paracetamol toxicity.

Side effects

Side effects can include constipation, skin rashes, dizziness, sedation, shortness of breath, hypersensitivity reaction, fainting (syncope or near syncope), nausea and/or vomiting, confusion, loss of short-term memory, drowsiness, changes in blood, allergic reactions, euphoria, dysphoria, abdominal pain, pruritus (itching), easy bruising, bleeding gums, vivid dreams, dry mouth and addiction.

Genetic differences between people give rise to differing rates of metabolism of codeine to morphine. In about 5% of people this may happen particularly fast, leading to higher levels of morphine being passed through breast milk in amounts potentially able to cause fatal respiratory depression of a breastfed baby.[3]
