Warnings and precautions

Finish the whole course even after you feel better — stopping early breeds resistant bacteria. Tell your doctor if you have ever had a severe reaction to penicillin; a small proportion of people react to both groups. Report severe or watery loose motions during or after the course rather than treating them yourself. Several medicines in this group are on Schedule H1 precisely because overuse drives antibiotic resistance. Take it only when a doctor has prescribed it for you.

Do not take Omnicef O if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for anyone with a known allergy to cephalosporin antibiotics.

Interactions with other medicines

Antacids, iron and zinc reduce absorption — separate them by a couple of hours. Tell your doctor if you take a blood thinner.
