Diclofenac vs Ibuprofen: Nigeria's favourite strong painkiller vs the safer default
The short answer
Diclofenac hits inflammatory pain hard — which is exactly why Nigerians love it and why it deserves respect: it carries the higher ulcer and heart risk of the two. Ibuprofen is the safer default for short-term aches. Use diclofenac at the lowest dose for the shortest time, always with food, and not at all if you have ulcer, heart, or kidney history.
Ask for 'something strong for body pain' in many chemists and you'll be handed diclofenac — as tablets, or the Cataflam sachets people stir into water. It is a genuinely powerful NSAID, often felt to work faster and deeper than ibuprofen for back pain, arthritis flares, and injuries. The catch is that its extra punch comes with the class's risks amplified: among common NSAIDs, diclofenac sits at the higher-risk end for both stomach bleeding and cardiovascular strain, especially used daily for weeks.
The pattern that causes harm here is familiar: daily diclofenac for chronic waist or joint pain, bought loose, no food, for months — then a bleeding ulcer 'from nowhere'. If pain is chronic enough to need daily NSAIDs, that's a diagnosis question for a clinician, and there are safer long-term strategies. For the occasional heavy ache, either drug is reasonable; diclofenac just demands more discipline.
