Codeine/paracetamol, also known as codeine/acetaminophen and co-codamol, is a compound analgesic consisting of a combination of codeine phosphate and paracetamol (acetaminophen). Codeine/paracetamol is used for the relief of mild to moderate pain when paracetamol or non-steroidal anti-inflammatory drug (NSAIDs) such as ibuprofen, aspirin or naproxen alone do not sufficiently relieve symptoms.[2][3]

In 2020, it was the 187th most commonly prescribed medication in the United States, with more than 2 million prescriptions.[6][7]

Side effects[edit]

The most common side effects of co-codamol are constipation and feeling sick (nausea) or sleepy.[8] Other side effects may include blood from mouth, skin rashes, dizziness, sedation, shortness of breath, hypersensitivity reaction, fainting (syncope or near syncope), confusion, loss of short-term memory, changes in blood, allergic reactions, euphoria, dysphoria, abdominal pain, itchiness, easy bruising, bleeding gums, vivid dreams, dry mouth and addiction.[9]

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.[10]

Society and culture[edit]


Of the European Union (EU) member states, 12 countries (Bulgaria, Cyprus, Denmark, Estonia, France, Ireland, Latvia, Lithuania, Malta, Poland, Romania, Slovenia) allow over-the-counter sale of OTC codeine solid dosage forms.[11]
