How it works

Inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby decreasing pain, fever, and inflammatory responses. This mechanism provides analgesic, antipyretic, and anti-inflammatory effects across multiple pain conditions.

How to take this drug

Adults should take 200 mg to 400 mg (one to two tablets) every 6 to 8 hours as needed, with food or a glass of water to protect your stomach. Do not take more than 1200 mg (three 400 mg tablets) in a day unless a doctor tells you otherwise. Common brands in Nigeria include Afrab Ibuprofen 400 mg, Alieve 400 mg, and AC-Ibu 200 Tablet.

What if I Miss a Dose?

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue as normal. Never take a double dose to make up for the one you missed.

What to watch out for

Always buy from a reputable pharmacy — avoid buying ibuprofen from roadside sellers or bus hawkers, as fake or expired drugs are common. Do not use ibuprofen for more than 3 days for fever or 5 days for pain without seeing a doctor. Taking it on an empty stomach regularly can cause serious stomach problems, so always eat something before you take it.

Common Side Effects

Stomach pain or upset stomach
nausea (feeling like you want to vomit)
heartburn or chest burning sensation
dizziness
mild headache

Serious Side Effects

Black or bloody stool (this could mean stomach bleeding — go to the hospital immediately)
severe stomach pain that does not go away
swelling of the face
lips or throat with difficulty breathing (this is a serious allergic reaction — seek emergency help at once)

Drug Interactions

Avoid taking ibuprofen with aspirin or other painkillers like diclofenac at the same time, as this increases the risk of stomach bleeding. If you are taking blood pressure drugs, ibuprofen can reduce their effectiveness — talk to your doctor. Avoid drinking alcohol while using ibuprofen, as it increases the chance of stomach damage.
