- If you’ve bought co-dydramol from a pharmacy, do not use it for more than 3 days without talking to your doctor.

If you’re taking co-dydramol as a liquid, it will come with a plastic
spoon or syringe to help you measure the correct amount. Ask your
pharmacist for one if you don’t have it. Do not measure the liquid with a
kitchen teaspoon because it won’t give the right amount.
It’s important to leave a gap of at least 4 hours between doses of
co-dydramol. Taking too much can be very dangerous because the
paracetamol in it can cause liver damage.
Different strengths of co-dydramol
Co-dydramol comes in 4 different strengths. The tablets contain either 7.46mg, 10mg, 20mg or 30mg of dihydrocodeine.
All co-dydramol tablets also contain 500mg of paracetamol – the same as in a standard paracetamol tablet or capsule.
The strength is shown as 2 numbers on the packet.
These indicate the amount of dihydrocodeine followed by the amount of
paracetamol. So if 10/500 is written on the packet, this means the
tablets contains 10mg of dihydrocodeine and 500mg of paracetamol.
You can buy the lowest strength of co-dydramol (7.46/500) without a
prescription from a pharmacy. The higher strengths (10/500, 20/500 and
30/500) are only available on prescription.
How much to take
adults (16 years and older) – 1 to 2 co-dydramol tablets (of any strength) up to 4 times in 24 hours. Always leave at least 4 hours between doses.

other medicines that contain paracetamol. These include painkillers
such as Tramacet (paracetamol combined with tramadol) and co-codamol, migraine remedies, and some cough and cold remedies such as Lemsip and Night Nurse.
Co-dydramol already contains paracetamol, so you could be at risk of a paracetamol overdose.
