Levofloxacin can be used for lesions caused by Staphylococcus aureus infections. Levofloxacin is a quinolone antimicrobial drug, so lesions caused by pathogens that are sensitive to this drug can be treated with levofloxacin under the supervision of a physician. There are many pathogens that are sensitive to levofloxacin, and Staphylococcus aureus, a gram-positive aerobic bacterium, is one of them. Therefore, if one has an infection due to Staphylococcus aureus, the drug can be used empirically, but if the drug sensitivity results show resistance to levofloxacin, the antimicrobial drug will need to be changed. ADVERSE REACTIONS: The use of levofloxacin may cause a number of adverse reactions, the most common of which include diarrhea, nausea, headache, insomnia, constipation, and dizziness. Contraindications: Levofloxacin is contraindicated in people who are allergic to quinolone antibiotics, people under 18 years of age, pregnant women, and breastfeeding women. Precautions: The use of levofloxacin can lead to an increased risk of tendonitis and tendon rupture, and individuals with Achilles tendon rupture may require surgical repair. Individuals with myasthenia gravis should avoid using levofloxacin. Levofloxacin needs to be used as prescribed by a doctor and should not be used privately. In addition, if some unusual and serious adverse reactions occur after the use of the drug, the physician should be informed promptly for treatment.
