Drug information provided by: Merative, Micromedex®
Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.
This medicine comes with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.
This medicine works best when there is a constant amount in the blood or urine. To help keep the amount constant, do not miss any doses. Also, it is best to take the doses at evenly spaced times, day and night. For example, if you are to take one dose a day, try to take it at the same time each day.
If you need to take this medicine for anthrax infection, your doctor will want you to begin using it as soon as possible after you are exposed to anthrax.
You may swallow the Cipro® tablet whole or break it in half at the score line. Do not crush or chew it. Tell your doctor if you have trouble swallowing the tablet.
Swallow the extended-release tablet whole. Do not crush, split, or chew it.
Shake the oral liquid for at least 15 seconds just before each use. The oral liquid has small microcapsules floating in it. These microcapsules may look like bubbles or small beads. Do not chew the microcapsules when you take the oral liquid. Measure the oral liquid with the marked measuring spoon that comes with the bottle.
You may take this medicine with or without food. However, Proquin® XR tablets should be taken with a main meal, preferably the evening meal.
Drink plenty of fluids while you are using this medicine. Drinking extra water will help prevent some unwanted effects of ciprofloxacin.
Do not take this medicine alone with milk, yogurt, or other dairy products. Do not drink any juice with calcium added when you take this medicine. It is okay to have dairy products or juice as part of a larger meal when you take this medicine.
If you are taking aluminum or magnesium-containing antacids, iron supplements, multivitamins, didanosine (Videx®), lanthanum carbonate (Fosrenol®), sevelamer (Renagel®), sucralfate (Carafate®), or any products containing calcium or zinc, do not take them at the same time that you take this medicine. It is best to take these medicines at least 2 hours before or 4 to 6 hours after taking ciprofloxacin. These medicines may keep ciprofloxacin from working properly.
Keep using this medicine for the full treatment time, even if you feel better after the first few doses. Your infection may not clear up if you stop using the medicine too soon.
