Usage Instructions

Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking ciprofloxacin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually twice a day in the morning and evening.

The tablet may have a bitter taste if you split, chew, or crush it before taking it. The manufacturer recommends swallowing the tablet whole for this reason.

The dosage and length of treatment is based on your medical condition and response to treatment. Drink plenty of fluids while taking this medication unless your doctor tells you otherwise.

Take this medication at least 2 hours before or 6 hours after taking other products that may bind to it, decreasing its effectiveness. Ask your pharmacist about the other products you take. Some examples include: quinapril, sevelamer, sucralfate, vitamins/minerals (including iron and zinc supplements), and products containing magnesium, aluminum, or calcium (such as antacids, didanosine solution, calcium supplements).

Calcium-rich foods, including dairy products (such as milk, yogurt) or calcium-enriched juice, can also decrease the effect of this medication. Take this medication at least 2 hours before or 6 hours after eating calcium-rich foods, unless you are eating these foods as part of a larger meal that contains other (non-calcium-rich) foods. These other foods decrease the calcium binding effect.

Ask your doctor or pharmacist about safely using nutritional supplements/replacements with this medication.

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 persists or worsens.


Store at room temperature away from light and moisture. Do not store in the bathroom. Keep all medications away from children and pets.

Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed. Consult your pharmacist or local waste disposal company.
