Explore this drug
Adults usually take one 500 mg capsule every 6 hours (4 times a day) or every 12 hours depending on the infection. You can take it with or without food, but taking it with food can reduce stomach upset. Drink plenty of water and complete the full course your doctor or pharmacist prescribed — usually 7 to 14 days. Common brands in Nigeria include Monacef 500, Cephaflash Capsules, and Axcel Cephalexin-500.
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 your normal schedule. Do not take a double dose to make up for it.
Important for antibiotics
Always complete the full course even if you feel better. Stopping early can cause the infection to return and become drug-resistant.
Always complete the full course of cefalexin even if you feel better — stopping early can cause the infection to come back stronger and harder to treat. Buy only from licensed pharmacies — avoid roadside sellers or open market drugs, as fake antibiotics are common in Nigeria. Do not share your cefalexin with anyone else, even if they have similar symptoms — the wrong antibiotic or wrong dose can be dangerous.
Metformin (used for diabetes) — cefalexin can increase metformin levels in the body, so monitor your blood sugar closely. Blood thinners like warfarin — cefalexin may increase the risk of bleeding, so inform your doctor. Probenecid (used for gout) — it can increase cefalexin levels in your blood, making side effects more likely.
Check your specific combination
Is it safe to take Cefalexin with your other drugs?
Cefalexin is generally considered safe during pregnancy and breastfeeding, but always consult your doctor before using it to be sure it is right for your situation.
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 in cars. Keep capsules in their original container. If you are using the suspension (syrup), store it in the refrigerator after mixing and use it within 14 days. Always keep out of reach of children.
