4. How and when to take co-codamol

It’s important to take co-codamol as your doctor has asked you to. This is particularly important because co-codamol can be addictive.

Co-codamol comes as tablets and capsules. Swallow them whole with a drink of water.

Co-codamol also comes as soluble tablets that dissolve in water to make a drink.

You can take co-codamol with or without food.

Different co-codamol strengths

Co-codamol tablets and capsules come in 3 different strengths.

They contain 8mg, 15mg or 30mg of codeine.

All 3 strengths contain 500mg of paracetamol – the same as in a standard paracetamol tablet or capsule.

The strength of co-codamol appears as 2 numbers on the packet. For example, 8/500 means each tablet or capsule contains 8mg of codeine and 500mg of paracetamol.

You can buy the lowest strength of co-codamol (8/500) without a prescription but only from a pharmacy. The higher strengths (15/500 and 30/500) are only available on prescription from a doctor.


Adults and young people aged 16 years and older can take 1 or 2 tablets (of any strength) up to 4 times in 24 hours. Always leave at least 4 to 6 hours between doses. The maximum dose is 8 co-codamol tablets in 24 hours.

It’s important to leave a gap between doses of co-codamol. Taking too much co-codamol can be very dangerous. That’s because the paracetamol in it can cause liver damage.

Do not increase the dose of co-codamol or take a double dose even if your pain is very bad.


The maximum dose of co-codamol for adults and young people aged 16 years and over is 8 tablets in 24 hours.

How long to take it for

If your doctor has prescribed co-codamol for you, take it as you’ve been advised.

If you’ve bought co-codamol from a pharmacy, do not use it for more than 3 days. If you still have pain, talk to your pharmacist or doctor.


If you have been taking co-codamol for more than a few weeks do not stop taking it without speaking to your doctor first.

What if I take too much?

If you take 1 or 2 extra tablets of co-codamol by accident on a single occasion, it’s unlikely to be harmful. If this happens, wait at least 24 hours before you take any more.
