Take this medication by mouth with or without food as directed by your doctor, usually once a day. In children, this medication may also be taken twice a day (every 12 hours). The dosage is based on your medical condition and response to treatment. Children's dosage is also based on weight.

Shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

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 use 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.
