Alevo (Levofloxacin) 100 mg
Generic Name: Levofloxacin
Why is this medication prescribed?
Levofloxacin is used to treat certain infections such as pneumonia, and kidney, prostate (a male reproductive gland), and skin infections. Levofloxacin is also used to prevent anthrax (a serious infection that may be spread on purpose as part of a bioterror attack) in people who may have been exposed to anthrax germs in the air, and treat and prevent plague (a serious infection that may be spread on purpose as part of a bioterror attack. Levofloxacin may also be used to treat bronchitis, sinus infections, or urinary tract infections but should not be used for bronchitis and certain types of urinary tract infections if there are other treatment options available. Levofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections.
Antibiotics such as levofloxacin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
How should this medicine be used?
Levofloxacin comes as a tablet and a solution (liquid) to take by mouth. It is usually taken once a day. The length of your treatment depends on the type of infection you have. Your doctor will tell you how long to take levofloxacin. The tablet may be taken with or without food. The solution should be taken 1 hour before or 2 hours after eating. Take levofloxacin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take levofloxacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
You should begin to feel better during the first few days of treatment with levofloxacin. If your symptoms do not improve or if they get worse, call your doctor.
Take levofloxacin until you finish the prescription, even if you feel better. Do not stop taking levofloxacin without talking to your doctor unless you experience certain serious side effects listed in the IMPORTANT WARNING or SIDE EFFECTS sections. If you stop taking levofloxacin too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Other uses for this medicine
Levofloxacin is also sometimes used to treat endocarditis (infection of the heart lining and valves), certain sexually transmitted diseases, salmonella (an infection that causes severe diarrhea), shigella (an infection that causes severe diarrhea), inhalation anthrax (a serious infection that may be spread by anthrax germs in the air on purpose as part of a bioterror attack), and tuberculosis (TB).

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
