Ciprofloxacin may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using ciprofloxacin, tell your doctor or pharmacist if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using ciprofloxacin safely.

This medication may rarely cause serious changes in blood sugar levels, especially if you have diabetes. Watch for symptoms of high blood sugar including increased thirst and urination. Also watch for symptoms of low blood sugar such as nervousness, shakiness, fast heartbeat, sweating, or hunger. Check your blood sugar regularly as directed by your doctor and report any changes. If you experience symptoms of low blood sugar, you may raise your blood sugar by using glucose tablets/gel or eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor immediately about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals.

What is the most important information I should know about ciprofloxacin (Proquin XR)?

You should not use this medication if you are taking tizanidine (Zanaflex), or if you are allergic to ciprofloxacin or similar antibiotics such as levofloxacin (Levaquin), moxifloxacin (Avelox), ofloxacin (Floxin), norfloxacin (Noroxin), lomefloxacin (Maxaquin), and others.

Do not take ciprofloxacin with dairy products such as milk or yogurt, or with calcium-fortified juice. You may eat or drink dairy products or calcium-fortified juice with a regular meal, but do not use them alone when taking ciprofloxacin. They could make the medication less effective.

Before taking ciprofloxacin, tell your doctor if you have kidney or liver disease, myasthenia gravis, joint problems, diabetes, a history of seizures, low levels of potassium in your blood (hypokalemia), or a personal or family history of "Long QT syndrome."

Avoid taking antacids, vitamin or mineral supplements, sucralfate (Carafate), or didanosine (Videx) powder or chewable tablets 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.

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.
