Plain dihydrocodeine can generally be taken alongside paracetamol when both are used as directed. However, some medicines, such as co-dydramol, already contain paracetamol. Taking extra paracetamol on top of those can push you over the safe daily limit without you realising. Always check the label first.
Important safety note: This article is general information, not personal medical advice. Whether this combination is suitable depends on your health, your other medicines and the exact product you have. If you’re unsure, ask a pharmacist, your GP or NHS 111.
Can You Take Paracetamol With Dihydrocodeine?
In most cases, yes. Paracetamol and dihydrocodeine belong to different types of painkiller and work in different ways:
- Paracetamol is a non-opioid painkiller. It is used to relieve pain and reduce fever. It is not an anti-inflammatory and is not related to opioids.
- Dihydrocodeine is an opioid painkiller, used for moderate to severe pain when simpler painkillers aren’t enough.
Because they work differently, doctors often use them together as part of a pain-relief plan. NHS guidance notes that some medicines combine dihydrocodeine with other painkillers such as paracetamol.
That said, “generally fine together” is not the same as “safe for everyone in any amount”. Three things matter:
- Which product you have. Plain dihydrocodeine and co-dydramol are different situations (see below).
- Following the prescription and leaflet. Don’t change the dose or timing yourself.
- Your circumstances. Liver or kidney problems, low body weight, other medicines and alcohol use can all change the picture.
Can You Take Paracetamol With 30mg Dihydrocodeine?
If your tablets say “dihydrocodeine 30mg”, they are most likely dihydrocodeine 30mg, a prescription opioid painkiller. In that case, taking paracetamol alongside them is commonly done and is generally acceptable when each medicine is taken as directed. Paracetamol is not usually contained in plain dihydrocodeine tablets.
Before you do, check these points:
- Read the packaging and patient information leaflet. Look at the active ingredients. If paracetamol is listed, you already have it in your medicine.
- Be careful with “30mg” on combination products. Co-dydramol comes in several strengths, and one of them has 30mg of dihydrocodeine per tablet (alongside 500mg paracetamol). The “30mg” refers only to the dihydrocodeine, not the total medicine.
- Don’t adjust your dose yourself. The right amount and how long to take it depend on why it was prescribed and which type you have.
- Ask your pharmacist if anything is unclear. It takes a couple of minutes and can prevent a serious mistake.
Does Dihydrocodeine Contain Paracetamol?
It depends on the product.
Plain dihydrocodeine (for example, 30mg tablets) contains dihydrocodeine only. It does not automatically contain paracetamol.
Combination medicines do contain both. The best known in the UK is co-dydramol, which is dihydrocodeine plus paracetamol in one tablet.
If you’ve been given something labelled “dihydrocodeine and paracetamol”, “dihydrocodeine with paracetamol” or “co-dydramol”, you are already taking both ingredients.
What Is Co-Dydramol, and How Is It Different From Dihydrocodeine?
Co-dydramol is a combination painkiller containing dihydrocodeine and paracetamol. It’s used for pain that needs more than a simple painkiller but is not severe enough to need something stronger.
| Medicine | Contains dihydrocodeine? | Contains paracetamol? |
|---|---|---|
| Plain dihydrocodeine | Yes | Not automatically |
| Paracetamol | No | Yes |
| Co-dydramol | Yes | Yes |
Co-dydramol is available in more than one strength, and the amount of each ingredient depends on the product. For example, the 10mg/500mg tablet contains 10mg dihydrocodeine and 500mg paracetamol. Always check the strength printed on your own box.
Can You Take Extra Paracetamol With Co-Dydramol?
Do not take extra paracetamol with co-dydramol unless a doctor or pharmacist has specifically told you to.
Co-dydramol already contains paracetamol. Adding paracetamol tablets, or other products that contain it, means you can easily exceed the maximum daily amount without noticing. Too much paracetamol can cause serious liver damage, sometimes with no obvious symptoms at first.
Paracetamol is also found in many everyday products, including:
- Cold and flu remedies (powders, hot drinks, capsules)
- Some migraine and headache products
- Other combination painkillers such as co-codamol
Check the “active ingredients” list on everything you take. If you see “paracetamol” or “acetaminophen” more than once across your medicines, stop and ask a pharmacist before taking the next dose.
Why Are Paracetamol and Dihydrocodeine Used Together?
Pain is rarely controlled well by one mechanism alone. Paracetamol and dihydrocodeine act on pain in different ways, so using them together can give better relief than either on its own, and sometimes at lower opioid doses. This is the thinking behind combination painkillers and “stepped” pain relief, where stronger medicines are added only if simpler ones don’t control the pain.
After surgery or injury, doctors often plan pain relief this way and then step the stronger medicines down as you recover. If you were given a plan, follow it rather than improvising.
Can You Take Ibuprofen With Dihydrocodeine and Paracetamol?
Ibuprofen is an NSAID (non-steroidal anti-inflammatory drug), so it is a different type of painkiller again. It is sometimes used alongside paracetamol and an opioid, but it isn’t suitable for everyone, so don’t assume you can add it.
Check with a pharmacist or doctor first if you:
- Have had a stomach ulcer or bleeding in the digestive system
- Have asthma, kidney problems, heart disease or high blood pressure
- Take blood thinners (anticoagulants), other anti-inflammatories or certain blood pressure medicines
- Are pregnant, or are over 65
Can You Drink Alcohol With Dihydrocodeine and Paracetamol?
It’s best to avoid it. Dihydrocodeine can make you drowsy and dizzy, and alcohol increases that sleepiness. NHS guidance advises avoiding alcohol while taking dihydrocodeine. Combining them can impair your alertness and, in some cases, slow your breathing.
Regular heavy alcohol use can also increase the risk of liver problems with paracetamol, so tell your pharmacist or doctor if you drink regularly.
If you feel drowsy or unsteady, don’t drive or use tools or machinery.
What Are the Side Effects of Dihydrocodeine?
Common side effects can include:
- Feeling or being sick
- Drowsiness or dizziness
- Constipation
- Dry mouth
- Headache
Eating regularly and drinking enough fluid can help with constipation. Ask a pharmacist about suitable treatment if it persists.
Get urgent help (call 999 or go to A&E) if you have:
- Slow, shallow or difficult breathing
- Extreme drowsiness, or you can’t be woken
- Swelling of the face, lips, tongue or throat, or a severe rash
- Confusion, fainting or a seizure
Like all opioids, dihydrocodeine can lead to tolerance and dependence, particularly with long-term use. Take it only as prescribed and for as long as needed, and speak to your doctor before stopping if you’ve taken it regularly.
Can Dihydrocodeine Interact With Other Medicines?
Yes. Rather than memorising a list, it helps to know the main categories to ask about:
- Other opioid painkillers, such as codeine, co-codamol, morphine, tramadol. Taking two opioids together increases the risk of serious side effects. Don’t combine them unless a doctor has told you to.
- Sedatives and sleep medicines, such as benzodiazepines (diazepam, for instance) and “Z-drugs” (such as zopiclone). These add to drowsiness and breathing risks.
- Some antidepressants and medicines for mental health conditions.
- Antihistamines that cause drowsiness, including some allergy and travel-sickness products.
- Other paracetamol-containing products, as covered above.
Herbal remedies and supplements can interact too. When you collect a prescription or buy anything over the counter, tell the pharmacist what else you take.
Who Should Speak to a Doctor or Pharmacist First?
Dihydrocodeine isn’t suitable for everyone, and paracetamol needs extra care in some people. Check before taking this combination if you:
- Have liver or kidney problems
- Have asthma, COPD, sleep apnoea or other breathing problems
- Have had a head injury or raised pressure in the head
- Have a history of drug or alcohol dependence
- Are pregnant, planning a pregnancy or breastfeeding
- Have a low body weight or are frail or elderly (paracetamol limits may be lower)
- Take any of the medicines listed above
What If You Take Too Much?
Taking too much paracetamol or dihydrocodeine is an emergency, even if you feel fine.
- Call 999 or go to A&E immediately if you suspect an overdose, or you have taken more than the recommended amount of either medicine. Take the packaging with you.
- Don’t wait for symptoms. Paracetamol overdose can seriously harm the liver before you feel unwell, and treatment works best when started early.
- Signs of opioid overdose include very slow or shallow breathing, extreme sleepiness, pinpoint pupils and blue lips. Call 999 straight away.
- If it’s not an emergency but you’re worried (for example, you’ve accidentally taken a dose too early), call NHS 111 or speak to a pharmacist.
When Should You Get Medical Advice About Your Pain?
See your GP or pharmacist if:
- Your pain isn’t controlled by the medicines you’ve been given
- You need to take painkillers for longer than expected
- You are getting side effects that bother you
- You feel you need more than prescribed, or you’re worried about dependence
Frequently Asked Questions
Can you take paracetamol with dihydrocodeine?
Generally yes, if you have plain dihydrocodeine and take both as directed. Check that your dihydrocodeine product doesn’t already contain paracetamol, and ask a pharmacist if you’re unsure.
Can you take paracetamol with 30mg dihydrocodeine?
Plain 30mg dihydrocodeine tablets don’t normally contain paracetamol, so the two can usually be used together as directed. However, co-dydramol also comes in a 30mg/500mg strength, which already includes paracetamol. Always read the label.
Does dihydrocodeine contain paracetamol?
Not on its own. Combination products such as co-dydramol contain both.
Is co-dydramol the same as dihydrocodeine and paracetamol?
Co-dydramol is a combination of dihydrocodeine and paracetamol in one tablet. It is available in different strengths, so check the amounts on your pack.
Can you take extra paracetamol with co-dydramol?
No, not unless a healthcare professional has told you to. Co-dydramol already contains paracetamol, and extra doses can lead to an overdose.
Can you take ibuprofen with dihydrocodeine and paracetamol?
Sometimes, but it depends on your health and other medicines. Check with a pharmacist or doctor first.
Can you drink alcohol while taking dihydrocodeine?
It’s best to avoid it. Alcohol increases drowsiness and the risk of side effects.
Can you take dihydrocodeine with codeine?
No, not unless a doctor has specifically advised it. Both are opioids, and combining them increases the risk of serious side effects. Co-codamol also contains codeine.
What are the side effects of dihydrocodeine?
The most common are nausea, drowsiness, dizziness, constipation, dry mouth and headache. Serious reactions include slow breathing and severe allergic reactions and need emergency help.
What should you do if you take too much dihydrocodeine or paracetamol?
Call 999 or go to A&E straight away, even if you feel well, and take the packaging with you.
