Co-dydramol is a mixture of 2 different painkillers: paracetamol and dihydrocodeine. Dihydrocodeine belongs to a group of medicines called opiates.
It's used to treat aches and pains, including headaches, migraines, muscle and joint pain, period pain and toothache.
Paracetamol and dihydrocodeine work by blocking messengers in the nerves and brain that tell your body that you're in pain.
You'll usually take co-dydramol when everyday painkillers such as aspirin, ibuprofen and paracetamol have not worked on their own.
Co-dydramol comes in 4 different strengths. You can buy lower-strength tablets from pharmacies. Higher-strength tablets are only available on prescription.
Co-dydramol usually comes as tablets.
