Co-dydramol

About co-dydramol

Co-dydramol is a mixture of 2 different painkillers: paracetamol and dihydrocodeine.

It's used to treat aches and pains, including headaches, migraines, muscle and joint pain, period pain and toothache.

You will usually take co-dydramol when everyday painkillers – such as aspirin, ibuprofen and paracetamol – have not worked on their own.

This medicine usually comes as tablets.

You can buy lower-strength tablets from pharmacies. Higher-strength tablets are only available on prescription.

Key facts

  • Co-dydramol comes in 4 different strengths. You can buy the lowest-strength tablets from pharmacies. Higher strengths are only available on prescription.
  • The most common side effects of co-dydramol are constipation and feeling sick or sleepy.
  • If you've bought co-dydramol from a pharmacy, do not use it for more than 3 days without talking to your doctor.
  • It's possible to become addicted to the dihydrocodeine in co-dydramol. However, this is rare if you're taking it as a painkiller and your doctor reviews your treatment regularly.

Who can and cannot take co-dydramol

Adults and children aged 12 years and over can take co-dydramol.

Important

Do not give co-dydramol to a child under the age of 12 years unless their doctor prescribes it.

Co-dydramol is not suitable for some people. Tell your doctor before starting this medicine if you:

  • have had an allergic reaction to co-dydramol, paracetamol, dihydrocodeine or any other medicine in the past
  • have any problems with your digestion, such as irritable bowel syndrome or Crohn's disease
  • have lung problems, asthma or other breathing difficulties
  • have a head injury
  • have adrenal gland problems
  • have a condition that causes seizures or fits
  • have an underactive thyroid
  • regularly drink more than the maximum recommended amount of alcohol (14 units a week)
  • have liver or kidney problems
  • have myasthenia gravis, a rare illness that causes muscle weakness
  • are trying to become pregnant, are already pregnant or are breastfeeding
  • are under 18 years and have had your tonsils or adenoids taken out because of obstructive sleep apnoea

How and when to take co-dydramol

You can take co-dydramol with or without food.

Swallow the tablets whole with a drink of water. Do not crush them.

Some tablets have a line down the middle to help you break them into 2 halves. If you have trouble swallowing medicines, break the tablet and then take each half separately.

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 give the amount of dihydrocodeine followed by the amount of paracetamol. So if it says 10/500 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.

Dosage

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.

Children (12 to 15 years) – 1 tablet up to 4 times in 24 hours. If your child has been prescribed co-dydramol, follow the doctor's instructions. Always leave at least 4 hours between doses.

Important

The maximum dose in 24 hours for:

  • adults is 8 co-dydramol tablets
  • children is 4 co-dydramol tablets, unless their doctor prescribes a higher dose

How long to take it for

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

If your doctor prescribed co-dydramol for you, take it for as long as they tell you to.

What if I forget to take it?

If you take co-dydramol regularly and miss a dose, take it as soon as you remember. Unless it's nearly time for your next dose, in which case skip the missed dose and take your next one at the usual time.

Never take double doses of co-dydramol, and never take extra doses to catch up.

If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.

What if I take too much?

Important

Taking 1 or 2 extra tablets by accident is unlikely to be harmful, as long as you do not take more than 8 tablets in 24 hours.

Wait at least 24 hours before taking any more co-dydramol.

If you need to go to A&E, do not drive yourself. Get someone else to drive you or call for an ambulance.

Take the co-dydramol box, or the leaflet inside the packet, plus any remaining medicine with you.

Taking co-dydramol with other painkillers

It's safe to take co-dydramol with ibuprofen or aspirin. However, do not give aspirin to children under the age of 16 (unless their doctor prescribes it).

Do not take co-dydramol with paracetamol or 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.

Important

Before taking any other medicines, check the label to see whether they contain paracetamol.

Side effects

Like all medicines, co-dydramol can cause side effects, although not everyone gets them. Many people have no side effects or only minor ones. You are more likely to have side effects if you take the higher strengths of co-dydramol.

Common side effects

Common side effects happen in more than 1 in 100 people. Tell your doctor if the side effects bother you or do not go away. Common side effects include:

  • constipation
  • feeling or being sick (nausea or vomiting)
  • feeling sleepy
  • headaches

Serious side effects

Serious side effects are rare and happen in less than 1 in 100 people.

Tell a doctor straight away if you have:

  • a skin rash
  • difficulty peeing
  • changes in your eyesight
  • dizziness

Serious allergic reaction

In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to co-dydramol.

These are not all the side effects of co-dydramol. For a full list, see the leaflet inside your medicine packet.

How to cope with side effects of co-dydramol

What to do about:

  • constipation - eat more high-fibre foods, such as fresh fruit and vegetables, and cereals. Try to drink several glasses of water or another non-alcoholic liquid each day. If you can, try to exercise more regularly – for example, by going for a daily walk or run.
  • feeling or being sick - try taking co-dydramol with or just after a meal or snack. Stick to simple meals and do not eat rich or spicy food. If you're being sick, try small frequent sips of water to avoid dehydration. Feelings of sickness should normally wear off after a few days. Talk to your doctor about taking an anti-sickness medicine if it carries on for longer.
  • feeling sleepy - this side effect should go away within a few days as your body gets used to the dihydrocodeine. Do not drive, cycle or use tools or machinery if you're feeling this way. Do not drink any alcohol, as this will make you feel more tired. Speak to your doctor if it carries on for longer.
  • headaches - make sure you rest and drink plenty of fluids. Do not drink too much alcohol. Ask your pharmacist to recommend a painkiller. Talk to your doctor if the headaches last longer than a week or are severe.

Pregnancy and breastfeeding

Co-dydramol and pregnancy

Co-dydramol is not generally recommended during pregnancy. There may be safer medicines that you can take. Ask your doctor or pharmacist for advice.

Speak to your doctor or pharmacist before taking co-dydramol.

Co-dydramol and breastfeeding

Co-dydramol is not normally recommended while breastfeeding. This is because no one knows whether dihydrocodeine can get into breast milk.

If your doctor prescribes co-dydramol, follow their instructions. You will usually take it for a short time and at the lowest dose. Speak to your doctor or pharmacist straight away if your baby has any breathing problems.

Cautions with other medicines

Some medicines can affect the way co-dydramol works.

Tell your doctor if you're taking these medicines before you start taking co-dydramol:

Mixing co-dydramol with herbal remedies and supplements

There's not enough information to say that complementary medicines and herbal remedies are safe to take with co-dydramol. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.

RLS TREATMENT: Every day I read questions and answers on this forum and I would like to share with you some of my concerns

So, may I share with you what works for me and has been working for nearly a year: Combination Therapy: I take 0.28 mg of Prolonged Release Mirapex, 0.5 mg of Clonazepam and 2 Co-dydramol. I take one high strength Senokot in the evening for constipation.

Mirapexin Prolonged-Release

Before that I was on 1200 mg Gabapentin which did not work very well as I had to complement with Co-Dydramol every night. And before that I was for years on Pramiprexole and later on the Rotigotine Neupropatch.

MIRAPEXIN PROLONGED RELEASE

Combined use of 2x600 mg of Gabapentin, 2 co-dydramol and 0.5 mg of Clonazipam each night is still giving me insomnia and restless legs. I was so proud of myself coming off the Dopamine Agonists for 14 years and now he wants me to get back on.

Weaned off Pramipexole. Gabapentin?

I have tried 300 mg at about 10pm but that didn’t work too well and then topped that up at about 2am with another 300mg, together with some Co-dydramol which I take for back pain. I have then managed a few hours sleep. Any help or advice would be truly welcome. Many thanks

Help!

I was told to take co-dydramol continously and given exercises to do. Which I do but still the pain does not shift, the exercise gives some pain relief but doesn't help.

Is a combination of drugs the answer?

I had a lot of sleepless nights until I discovered it worked well with 2 co-dydramol (plus one Senekot to help with the constipation).

Where do I go from here?

Hi there, having been on the Neupropatch (3 mg) and Clonazipam (0.5 mg) since June 2017 (and Pramiprexole since 2006 until I augmented), over the last month I have increasingly been needing to take 2 co-dydramol at night to help me sleep and actually I take it every night now, otherwise hours of RLS.

Very worried

Hi, I suffer from eczema but it has always been under control and always a small patch on the back of my calf. However, about 6 weeks ago, it became very sore and itchy. It became infected and I was on antibiotics for two weeks. It almost cleared so I thought it would go on it’s own. Stupid me. 2 weeks
