Summary
What conditions levofloxacin is used for
Levofloxacin is used to treat bacterial infections, which are illnesses caused by harmful bacteria. It is commonly prescribed for respiratory infections like pneumonia, urinary tract infections, and skin infections. It is often used when other antibiotics are not suitable or when the bacteria are resistant to other treatments.
How levofloxacin works in the body
Levofloxacin works by killing bacteria. It blocks bacterial enzymes called DNA gyrase and topoisomerase IV, which are needed for bacteria to multiply and repair themselves. By stopping these enzymes, levofloxacin prevents bacteria from growing, helping to clear the infection from the body.
Directions for Use
Levofloxacin is usually taken as a tablet or liquid once daily. The typical dose for adults ranges from 500 mg to 750 mg, depending on the infection. It can be taken with or without food, but it's best to take it at the same time each day.
The most commonly observed adverse effects of levofloxacin
Common side effects of levofloxacin include nausea, diarrhea, headache, and dizziness. These effects are generally mild and temporary. If you experience any new or worsening symptoms, contact your doctor to determine if they are related to the medication.
Warnings and Precautions
Levofloxacin can increase the risk of tendonitis, which is inflammation of tendons, and tendon rupture. It may also cause nerve damage and affect blood sugar levels. People with allergies to fluoroquinolones or a history of tendon disorders should avoid it. Always follow your doctor's instructions and report unusual symptoms.
