What is Proquin XR?

Proquin XR (ciprofloxacin) is an antibiotic in a group of drugs called fluoroquinolones. It fights bacteria in the body.

Proquin XR is indicated only for the treatment of uncomplicated urinary tract infections (acute cystitis) caused by susceptible strains of Escherichia coli and Klebsiella pneumoniae. It is not interchangeable with other ciprofloxacin products such as Cipro.

Proquin XR may also be used for other purposes not listed in this medication guide.

Important information about Proquin XR

You should not use Proquin XR 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 Proquin XR 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 Proquin XR. They could make the medication less effective.

Before taking Proquin XR, 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 Proquin XR. These other medicines can make ciprofloxacin much less effective when taken at the same time.

Proquin XR 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 Proquin XR 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.

Before taking Proquin XR

You should not use Proquin XR 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 Proquin XR, 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 Proquin XR. Before you take this medication, 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;
diabetes;
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 Proquin XR is harmful to an unborn baby. Do not use Proquin XR 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.

How should I take Proquin XR?

Proquin XR should be taken once a day for 3 days shortly after a main meal of the day, preferably the evening meal. Proquin XR does not work as well if you take it without a meal. You should try to take it at about the same time each day.

Take Proquin XR for all 3 days, even if you are feeling better. If you stop taking this medication before all 3 doses, it may not cure your bladder infection.

Proquin XR should be taken with the main meal of the day.

Do not split, crush, or chew the tablets. They must be swallowed whole. Tell your doctor if you cannot swallow tablets whole. Your doctor will prescribe a different medicine for you.

Do not take Proquin XR at the same time that you drink milk or juices with added calcium, unless you drink them with a main meal.

Many antacids and multivitamins may interfere with the absorption of ciprofloxacin if taken at the same time. Take Proquin XR at least 4 hours before or 2 hours after antacids that contain magnesium or aluminum. Proquin XR should also be taken at least 4 hours before or 2 hours after sucralfate, Videx (didanosine) chewable buffered tablets or pediatric powder, iron, calcium, and vitamins that contain zinc.

Take this medication for as many days as it has been prescribed for you even if you begin to feel better. Your symptoms may get better before the infection is completely treated. Store this medicine at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine.

Overdose symptoms may include seizures, urination problems, weakness, or blue lips with pale skin.

What should I avoid while taking Proquin XR?

You may be taking certain other medicines that should not be taken at the same time as Proquin XR. Avoid taking the following medicines within 6 hours before or 2 hours after you take Proquin XR. These other medicines can make Proquin XR 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 Proquin XR, because the medication can make the effects of caffeine stronger.

Avoid exposure to sunlight, sunlamps, or tanning beds. Proquin XR 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.

Proquin XR 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.
