What is a “diclofenac sodium and paracetamol” tablet, and what is it used for?
A diclofenac sodium + paracetamol tablet combines two pain-relief medicines: diclofenac (an NSAID) and paracetamol (acetaminophen). Together, they are used for short-term relief of pain and inflammation, such as aches, dental pain, musculoskeletal pain, and similar conditions where both an anti-inflammatory and an analgesic effect are wanted.
How do diclofenac and paracetamol work together?
- Diclofenac sodium reduces inflammation and pain by blocking prostaglandin production (NSAID mechanism).
- Paracetamol reduces pain (and fever) through actions in the central nervous system, but it is less anti-inflammatory than diclofenac.
Using them together can improve pain control compared with either medicine alone in some situations, but it also combines the safety considerations of both drugs.
What side effects should people watch for?
Because this is a combination of an NSAID plus paracetamol, side effects come from both medicines.
Common issues can include stomach upset. Diclofenac can also raise the risk of stomach irritation/ulcers and can affect the kidneys in some people. Paracetamol can damage the liver if taken in too-high doses or combined with other products that also contain paracetamol.
Stop and seek urgent care for symptoms like:
- Black/tarry stools, vomiting blood, or severe stomach pain (possible GI bleeding)
- Facial swelling, wheezing, severe rash, or difficulty breathing (possible allergy)
- Severe weakness, yellowing of the skin/eyes, or dark urine (possible liver injury)
- Reduced urination or sudden swelling (possible kidney issues)
How should you take it safely (dose and “don’t double up”)?
The biggest safety issue with paracetamol products is avoiding duplicate dosing. Many cold/flu medicines also contain paracetamol, so combining them can accidentally push you above the daily limit and increase liver risk.
With diclofenac/NSAIDs, people are usually advised to:
- Take it with food if it upsets the stomach
- Avoid alcohol when possible (raises GI and liver risk, depending on how much and your other meds)
- Avoid taking other NSAIDs at the same time (like ibuprofen, naproxen, aspirin for pain), unless a clinician tells you to
If you tell me the exact strength on the pack (for example, “diclofenac 50 mg + paracetamol 500 mg”), I can help interpret typical adult dosing guidance and what maximum daily limits to watch for.
Who should avoid or ask a clinician before using this combination?
It may be risky or unsuitable for people with:
- A history of stomach ulcers or GI bleeding
- Significant kidney disease, heart failure, or uncontrolled high blood pressure (NSAID risks)
- Liver disease or heavy alcohol use (paracetamol/liver risk)
- Aspirin/NSAID allergy or asthma triggered by NSAIDs
- Pregnancy (especially later pregnancy), unless specifically prescribed
If you share age, other medicines, and any history of ulcers, kidney/liver disease, or asthma, I can flag the most relevant cautions.
How is it different from taking diclofenac or paracetamol alone?
- Compared with paracetamol alone: it adds anti-inflammatory action, which can help if inflammation is part of the pain.
- Compared with diclofenac alone: it adds a different pain mechanism, but still carries diclofenac’s NSAID risks, so it is not “safer” in terms of stomach/kidney effects.
Does it treat fever as well?
Paracetamol treats fever. Diclofenac can also reduce pain and may lower temperature in some cases, but paracetamol is the primary fever-active component here.
Can it be taken with common medicines?
Because interactions depend on the exact ingredients and your other drugs, it’s important to check. In general:
- Avoid other paracetamol-containing products.
- Be cautious with blood thinners (like warfarin), antiplatelets, and other NSAIDs due to bleeding/GI risk.
- Some blood pressure medicines and diuretics can be affected by NSAIDs.
If you list your current medications, I can help identify common interaction concerns to discuss with a pharmacist or clinician.
What if you take too much?
Overdosing can cause serious harm:
- Too much paracetamol can lead to delayed, severe liver injury.
- Too much diclofenac can increase GI bleeding risk and kidney problems.
If overdose is possible, get urgent medical help immediately—timing matters for treatment.

Quick question so I can give a precise answer
What strength is on your tablet/blister (e.g., “diclofenac sodium ___ mg + paracetamol ___ mg”), and are you asking about use for pain/fever, dosing, side effects, or interactions?
