Co-codamol, ibuprofen and paracetamol can all be used for pain, but they are not interchangeable and there is no single “best” choice for every type of pain. Paracetamol reduces pain and fever, ibuprofen is an anti-inflammatory painkiller, and co-codamol combines paracetamol with codeine, an opioid.
The most suitable option depends on why the pain is happening, whether inflammation is involved, what other medicines you take and whether you have health conditions that affect which painkillers are safe for you. Co-codamol may be considered when everyday painkillers such as paracetamol or ibuprofen have not provided enough relief, but the codeine component also brings extra side effects and dependence risk.
| Medicine | Main role | What makes it different | Key safety point |
|---|---|---|---|
| Paracetamol | Pain relief and reduction of high temperature | Does not have the same anti-inflammatory effect as ibuprofen | Too much paracetamol can cause serious liver damage. Check other medicines for hidden paracetamol. |
| Ibuprofen | Pain, fever and inflammation | An NSAID that can reduce inflammation as well as pain | Not suitable for everyone, including some people with stomach, kidney, heart or asthma-related problems; pregnancy changes when it is appropriate. |
| Co-Codamol | Pain relief when simpler painkillers have not provided enough relief | Combines paracetamol with codeine, an opioid | Can cause drowsiness, constipation, tolerance, dependence and addiction. It already contains paracetamol. |
Co-codamol can provide additional pain relief compared with paracetamol alone because it contains codeine as well as paracetamol. However, it is misleading to say that co-codamol is stronger because it contains “more paracetamol”.
Common co-codamol tablets and capsules contain 500mg of paracetamol per tablet or capsule – the same amount found in a standard 500mg paracetamol tablet. What changes between common co-codamol strengths is the amount of codeine. The usual strengths are 8/500, 15/500 and 30/500, where the first number is the codeine amount and the second is the paracetamol amount.
The lowest strength can be supplied through a pharmacy, while higher strengths are prescription-only. A higher codeine strength does not automatically make a product the right choice for a particular person. Response to codeine varies, and stronger opioid exposure also increases the importance of side effects, driving safety and dependence risk.

Co-codamol and ibuprofen relieve pain in different ways. Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID), so it can reduce inflammation as well as pain. Co-codamol combines two analgesics – paracetamol and codeine – and does not work by reducing inflammation in the same way.
This means “which is stronger?” is often the wrong question. If swelling or inflammation is an important part of the pain, an anti-inflammatory such as ibuprofen may be relevant. If ordinary painkillers have not provided enough relief, co-codamol may sometimes be considered, provided it is appropriate for the person and used according to the medicine instructions or prescription.
The NHS notes that co-codamol may help when everyday painkillers such as ibuprofen, aspirin or paracetamol on its own have not worked. That does not mean co-codamol is automatically better for every toothache, headache, back problem or injury. The cause of the pain still matters.
Paracetamol reduces pain and fever, while ibuprofen reduces pain, fever and inflammation. That makes ibuprofen particularly relevant when inflammation is contributing to symptoms, but its anti-inflammatory action also means it has a different side-effect and suitability profile.
Paracetamol is commonly used during pregnancy, while systemic NSAIDs such as ibuprofen require more caution and are not appropriate at some stages of pregnancy. Ibuprofen is also unsuitable for some people with stomach, kidney, heart or asthma-related problems.
For adults, the NHS says paracetamol and ibuprofen can be taken at the same time if needed, although it is sensible to try them individually first to see whether one is enough. Always follow the label and check with a pharmacist or doctor if you have other medical conditions or take other medicines.
For pain or fever without an obvious inflammatory component, paracetamol is often a simple first option if it is suitable for you.
Where swelling or inflammation is part of the problem, ibuprofen may be more relevant because it is an anti-inflammatory medicine. However, people with certain stomach, kidney, heart, asthma or pregnancy-related considerations may need to avoid it or seek professional advice first.
Where pain has not been adequately relieved by everyday painkillers, co-codamol may sometimes be considered. It should not be treated as a routine “upgrade” simply because pain feels severe. Codeine can cause drowsiness, constipation, dependence and addiction, and the appropriate strength and duration depend on the exact product and clinical situation.
Persistent, unexplained or worsening pain should not be managed simply by moving from one stronger painkiller to another. The underlying cause may need assessment.
Do not take extra paracetamol with co-codamol unless a doctor has specifically advised you to do so. Taking two medicines that both contain paracetamol can lead to an accidental overdose and serious liver damage.
If you are unsure whether another medicine contains paracetamol, check the label or ask a pharmacist. Some cold and flu remedies and combination painkillers also contain it. For broader safe-use information, see the Co-Codamol dosage and safety guide.
The NHS states that co-codamol can be taken with ibuprofen. However, that does not make ibuprofen suitable for everyone. People who should avoid NSAIDs, or who take medicines that interact with them, should check with a pharmacist or doctor first.
Adults can take ibuprofen and paracetamol together if needed, according to NHS guidance. Try them individually first, use only the recommended doses on the labels, and avoid accidentally duplicating ingredients through combination medicines.
Paracetamol: Paracetamol very rarely causes side effects when taken correctly, but overdose can cause serious liver damage. Do not combine multiple paracetamol-containing products without checking the total amount.
Ibuprofen: Ibuprofen and other NSAIDs can cause stomach irritation and, more rarely, serious problems such as ulcers, bleeding or kidney problems. They are not suitable for everyone, and pregnancy changes when systemic NSAIDs can be used.
Co-codamol: The codeine in co-codamol can cause sleepiness, dizziness, nausea and constipation. Repeated opioid use can also lead to tolerance, dependence and addiction. Higher-strength co-codamol is prescription-only, and current patient information for 30/500 products warns against alcohol during treatment and against driving if the medicine makes you sleepy or dizzy.

Ask for professional advice if pain is persistent, keeps returning, is getting worse, or you regularly need pain relief to get through normal activities. You should also ask before combining medicines if you have long-term health conditions, are pregnant or breastfeeding, take other prescription medicines, or are unsure which ingredients are already present in a combination product.
Seek urgent medical advice if you have taken more paracetamol or co-codamol than the packet, leaflet or prescription allows, even if you initially feel well. Serious breathing difficulty, collapse, loss of consciousness or another life-threatening reaction requires emergency help.
Co-codamol can provide additional pain relief because it combines paracetamol with codeine, but “stronger” is not a fixed measure of how suitable it will be for an individual. Co-codamol strengths differ in their codeine content, and response to codeine can vary. It also has opioid-related risks that paracetamol alone does not have.
The common 8/500, 15/500 and 30/500 strengths each contain 500mg of paracetamol. The part that changes is the codeine amount. That is why you should not take extra paracetamol alongside co-codamol unless a doctor has specifically told you to do so.
There is no universal answer because they work differently. Ibuprofen reduces inflammation as well as pain, while co-codamol combines paracetamol with the opioid codeine. The more appropriate option depends on the cause of the pain, individual health factors, other medicines and whether simpler pain relief has already been tried.
Yes. NHS guidance says adults can take paracetamol and ibuprofen at the same time if needed, although it is sensible to try them individually first. Follow the label instructions and check with a pharmacist or doctor if you have medical conditions, take other medicines or are unsure whether an NSAID is suitable for you.
NHS guidance says co-codamol can be taken with ibuprofen, but ibuprofen is not suitable for everyone. Check with a pharmacist or doctor if you have a history of stomach ulcers, kidney or heart problems, asthma that reacts to NSAIDs, are pregnant, or take medicines that may interact with ibuprofen.
Paracetamol, ibuprofen and co-codamol are not simply three steps on a “weak to strong” ladder. Paracetamol mainly treats pain and fever, ibuprofen also targets inflammation, and co-codamol adds codeine to paracetamol when simpler pain relief has not been enough. The safest and most useful choice depends on the cause of the pain and the individual.
