Paracetamol vs Ibuprofen: which painkiller should you reach for?
The short answer
For everyday headache or fever, start with paracetamol — it is gentler on the stomach and safe in pregnancy. Reach for ibuprofen when there is swelling or inflammation behind the pain, like a sprain, toothache, or period pain, and take it with food.
Walk into any chemist in Nigeria with a headache and you will be offered one of these two. They are not interchangeable. Paracetamol brings down fever and dulls pain but does nothing for inflammation. Ibuprofen is an NSAID — it attacks the inflammation itself, which is why it works better for a swollen ankle or an aching tooth.
The price difference is small; the safety difference is not. Paracetamol taken correctly is one of the safest medicines there is (the danger is overdose — many cold remedies already contain it, so doses add up quietly). Ibuprofen is harder on the stomach lining and the kidneys, and anyone with an ulcer, kidney trouble, or in the last three months of pregnancy should leave it alone.
