What is ciprofloxacin?
Ciprofloxacin is an antibiotic in a group of drugs called fluoroquinolones (flor-o-KWIN-o-lones). Ciprofloxacin fights bacteria in the body.
Ciprofloxacin is used to treat different types of bacterial infections.
Ciprofloxacin may also be used for other purposes not listed in this medication guide.
You should not use ciprofloxacin if you are also taking tizanidine (Zanaflex), or if you are allergic to ciprofloxacin or similar medications such as levofloxacin (Levaquin), lomefloxacin (Maxaquin), moxifloxacin (Avelox), ofloxacin (Floxin), norfloxacin (Noroxin), and others.
Before taking ciprofloxacin, tell your doctor if you have a heart rhythm disorder, especially if you are being treated with one of these medications: quinidine (Cardioquin, Quinidex, Quinaglute), disopyramide (Norpace), bretylium (Bretylol), procainamide (Pronestyl, Procan SR), amiodarone (Cordarone, Pacerone), or sotalol (Betapace).
If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before you take ciprofloxacin, tell your doctor if you have:
- a history of allergic reaction to an antibiotic;
- joint problems;
- myasthenia gravis;
- kidney or liver disease;
- epilepsy or seizures;
- low levels of potassium in your blood (hypokalemia); or
- a personal or family history of "Long QT syndrome."
FDA pregnancy category C. It is not known whether ciprofloxacin is harmful to an unborn baby. Do not use ciprofloxacin without telling your doctor if you are pregnant. Tell your doctor if you become pregnant during treatment.
Ciprofloxacin passes into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Ciprofloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles’ tendon of the heel. These effects may be more likely to occur if you are over 60, if you take an oral steroid medication, or if you have had a kidney, heart, or lung transplant. Stop taking ciprofloxacin and call your doctor at once if you have sudden pain, swelling, tenderness, stiffness, or movement problems in any of your joints. Rest the joint until you receive medical care or instructions.
Do not share this medication with another person (especially a child), even if they have the same symptoms you have.
You may be taking certain other medicines that should not be taken at the same time as ciprofloxacin. Avoid taking the following medicines within 6 hours before or 2 hours after you take ciprofloxacin. These other medicines can make ciprofloxacin much less effective when taken at the same time:
- antacids that contain calcium, magnesium or aluminum (such as Tums, Mylanta, or Rolaids);
- the ulcer medicine sucralfate (Carafate);
- didanosine (Videx) powder or chewable tablets; or
- vitamin or mineral supplements that contain calcium, iron, or zinc.
Avoid caffeine while you are taking ciprofloxacin, because the medication can make the effects of caffeine stronger.
Avoid exposure to sunlight, sunlamps, or tanning beds. Ciprofloxacin can make your skin more sensitive to sunlight, and a sunburn may result. Wear protective clothing and use a sunscreen (SPF-15 or higher) if you must be out in the sun. Call your doctor if you have severe burning, redness, itching, rash, or swelling after being in the sun.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.
Ciprofloxacin can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
