What is Levaquin (Levofloxacin) prescribed for?

Bacterial and Viral Infections have many things common. Both types of infections are caused by microbes, and they spread by such things as; coughing and sneezing, contact with infected people, contact with contaminated surfaces, food and water, and contact with infected creatures such as live stock, insects and even your pets. This medication however, is used to treat a variety of bacterial infections, and it belongs to a class of drugs known as quinolone antibiotics.  It performs by stopping the growth of bacteria.  Remember this antibiotic only treats bacterial infections, it will however, not work on viral infections, such as the common cold and the flu. Using an antibiotic when not needed, it can cause it to not work for any future infections.

This medication comes in a singular dose of 500mg. Remember your dose is based on your medical background and your overall response to the treatment. If your doctor or pharmacist has given you some information in the form of a pamphlet, take the time to read up on this drug, and if you have any questions or concerns regarding this medication, please consult your doctor.

Before taking this medication, it is best to advise your doctor if you are allergic to Levofloxacin; or to other quinolone antibiotics (such as ciprofloxacin, moxifloxacin, ofloxacin); or to any other medications or allergies in general.

Also it is best to notify your doctor of your medical history. Inform you doctor if you have had any of the following; diabetes, joint/tendon problems (such as tendonitis, bursitis), kidney problems, mental/mood disorders (such as depression), a certain muscle condition (myasthenia gravis), nerve problems (such as peripheral neuropathy), seizure disorder, blood vessel problems (such as aneurysm or blockage of the aorta or other blood vessels, hardening of the arteries), high blood pressure, certain genetic conditions (Marfan syndrome, Ehlers-Danlos syndrome).

Levofloxacin may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using levofloxacin, tell your doctor or pharmacist of all the drugs you take and 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).
