Diclofenac
What it is used for

How it works
An NSAID that blocks prostaglandin production. It is a strong, fast painkiller for inflammation-driven pain.
How to take it
Typical adult doses are 50 mg two or three times a day, or one 75 to 100 mg slow-release tablet daily, after food. Swallow slow-release tablets whole. Injections are given by a health professional.

Be careful
Take after food. Can cause stomach bleeding and raise heart and kidney risk with long use.
Other medicines and interactions
Avoid with other NSAIDs and with blood thinners unless a doctor agrees. Can reduce the effect of blood pressure medicines and raise potassium and kidney risk with ACE inhibitors, ARBs and spironolactone. Raises lithium and methotrexate levels.
Pregnancy and breastfeeding
Avoid in the last three months of pregnancy and use earlier only on medical advice. Only small amounts pass into breast milk; short courses may be acceptable if a doctor agrees.
Paracetamol
What it is used for
Brings down fever and eases mild to moderate pain such as headache, body ache and toothache.
How it works
It works in the brain to raise the pain threshold and acts on the body's temperature centre to bring a fever down. Unlike NSAIDs it has little effect on swelling and is gentle on the stomach.
How to take it
Usual adult dose is 500 mg to 1 g every 4 to 6 hours, no more than 4 g (for example eight 500 mg tablets) in 24 hours; lower if you weigh under 50 kg, drink alcohol regularly or have liver disease. Children's doses go by weight. It can be taken with or without food.
Common side effects
- Side effects are rare at normal doses
- Occasionally rash or nausea
Get medical help straight away if
- You took more than the maximum dose, even if you feel well (liver damage shows up only after 1 to 3 days)
- Yellow skin or eyes
- A rash with blistering
Be careful
Too much damages the liver. Many cold and pain medicines also contain it, so avoid taking two at once; avoid with heavy alcohol use.
Other medicines and interactions
Many cold, flu and combination painkillers already contain paracetamol, so check every label to avoid a double dose. Regular high use can strengthen the effect of warfarin. Heavy alcohol use raises the risk of liver damage.
Pregnancy and breastfeeding
Paracetamol is the usual first choice for pain and fever in pregnancy and while breastfeeding, at the lowest dose that works for the shortest time.
