How it works

How to take this drug

Take one 20 mg capsule once daily, preferably in the morning before breakfast — swallow it whole with water, do not crush or chew. For severe ulcers, your doctor may increase it to 40 mg daily. A typical course lasts 2 to 8 weeks depending on your condition. Take it at the same time every day for best results.

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. Do not take two capsules at once to make up for it.

What to watch out for

Buy only from registered pharmacies — brands like AC-Ome 20, Gastrisafe, Bondpraz, or Cygnus 20 mg are common trusted brands in Nigeria, so avoid unregistered sellers. Do not use omeprazole for more than 2 weeks for simple heartburn without seeing a doctor, as long-term use without supervision can cause problems. If your stomach pain does not improve or gets worse after a few days, see a doctor — it may not just be ordinary ulcer.

Common Side Effects

Headache
stomach pain or gas
feeling like you want to vomit (nausea)
diarrhoea or constipation
dizziness

Serious Side Effects

Severe watery diarrhoea that won't stop (could be a sign of gut infection)
sudden skin rash with swelling of face or throat (allergic reaction)
and severe joint pain or bone fractures with long-term use — see a doctor immediately if any of these happen.

Drug Interactions

Omeprazole can reduce how well clopidogrel (a blood-thinning drug) works, so avoid using them together. It can also affect how your body absorbs ketoconazole and itraconazole (antifungal drugs commonly used in Nigeria). Alcohol can worsen stomach acid problems, so it is best to reduce or avoid alcohol while on this medication.

How to Store

Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be very hot, so avoid leaving it on windowsills or inside hot cars. Keep the capsules in their original pack and away from children.
