Antibiotic (Cephalosporin)
Last reviewed June 2026
Who is this for?
Cefdinir is an antibiotic that works by killing bacteria that cause infections in your body. It belongs to the cephalosporin family of antibiotics and stops bacteria from building their protective walls, which destroys them.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins and preventing cross-linking of peptidoglycan strands, resulting in bacterial cell wall degradation and death.
Prescription Required
You need a doctor's prescription to buy this drug.
Explore this drug
Adults usually take one 300 mg capsule twice a day or two 300 mg capsules once a day for 5 to 10 days, depending on the infection. You can take it with or without food. Swallow the capsule whole with a full glass of water and make sure you complete the full course your doctor or pharmacist prescribed.
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. Never take a double dose to make up for the one you missed.
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 antibiotic course even if you feel better after a few days — stopping early can make bacteria stronger and harder to treat next time. Buy only from licensed pharmacies and check for NAFDAC registration — avoid roadside or market sellers. Do not share your cefdinir with anyone else, even if they have similar symptoms.
Iron supplements and multivitamins containing iron can reduce how well cefdinir works — take them at least 2 hours apart. Antacids (like aluminium or magnesium-based ones used for ulcer or heartburn) also reduce absorption — space them out by at least 2 hours. Probenecid (used for gout) can increase cefdinir levels in your blood, so tell your doctor if you take it.
Check your specific combination
Is it safe to take Cefdinir with your other drugs?
Cefdinir has not been shown to be harmful during pregnancy, but you should only use it if your doctor says it is necessary; consult your doctor before taking it if you are pregnant or breastfeeding.
Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be hot, so avoid leaving it on window sills or in cars. Once the suspension is mixed with water, keep it in the fridge and use within 10 days. Always keep out of reach of children.
