This medication is a cephalosporin-type antibiotic used to treat a wide variety of bacterial infections (such as middle ear, skin, urine and respiratory tract infections). It works by stopping the growth of bacteria.

This antibiotic only treats bacterial infections. It will not work for viral infections (such as common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.

Shake the bottle well before each dose. Take this medication by mouth with or without food as directed by your doctor, usually every 8 or 12 hours. You may take this medicine with food if stomach upset occurs.

For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time(s) every day.

Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.

Tell your doctor if your condition lasts or gets worse.

Stomach upset, headache, nausea, vomiting, or diarrhea may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
