Antibiotics Home > What Is Levaquin Used For?

Levaquin is used for treating various types of bacterial infections in adults, including sinus infections, pneumonia, and bronchitis. The medication is also approved to prevent or treat plague, as well as prevent infection after exposure to inhaled anthrax, in both adults and children. Healthcare providers may occasionally recommend off-label Levaquin uses as well, such as for preventing infections (instead of treating them).

An Overview of Levaquin Uses

Levaquin® (levofloxacin) is an antibiotic used to treat a variety of different infections in adults, including:
Levaquin is also approved to prevent infection after exposure to inhaled anthrax in adults and children. In addition, it is licensed to prevent or treat plague infections in adults and children.
Levaquin is approved for treating the infections listed above only when they are caused by certain types of bacteria. Not all bacteria will respond to Levaquin. Also, bacteria have different resistance patterns in different regions of the country. This means that some bacteria may be susceptible to Levaquin in certain parts of the country but not in others. Levaquin is completely ineffective for treating viral illnesses (such as the common cold or the flu).
In some situations, your healthcare provider may perform certain tests to see if your particular infection is susceptible or resistant to Levaquin. In other situations, your healthcare provider may decide to try Levaquin without such tests, especially for infections that are not severe.
Levaquin is a "broad spectrum" antibiotic, which means it is effective against a wide variety of different types of bacteria. It is often used to treat an infection while tests are being done to see which antibiotics are effective for treating a specific infection. If the results of such tests show that an antibiotic with a narrower spectrum of activity will be effective, your healthcare provider may choose to switch you to such an antibiotic. Doing so may help limit antibacterial resistance, since overuse of broad spectrum antibiotics may increase the risk of developing bacteria that are resistant to medications.
