Levofloxacin is an antibiotic. It is used to treat bacterial infections of the lungs caused by a type of bacteria called Pseudomonas aeruginosa in individuals with cystic fibrosis (an inherited disease that causes excessively thick and sticky mucus build-up in the lungs, intestines, or other organs).
Use Levofloxacin exactly as directed by your doctor or according to the instructions on the label. Do not use more or less than instructed by your doctor.
Levofloxacin is available as a nebuliser solution, which will be used with a recommended nebuliser system.
Make sure you know how to use the device you have been given. If you have problems or do not understand the instructions, ask your doctor or pharmacist to show you how to use it.
The dose of this medicine will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on the type and severity of your infection.
Use Levofloxacin at regular intervals. Do not skip any doses. You must complete the entire course of this medicine. If you don't, the infection will not be properly controlled.
