Levofloxacin belongs to the quinolone class of drugs, with a relatively wide antibacterial spectrum, and is very effective against Staphylococcus aureus, Escherichia coli, Klebsiella spp. and Streptococcus pneumoniae. If the patient has pus in the tonsils, he can be treated with levofloxacin tablets or levofloxacin capsules. If the patient’s symptoms are particularly severe, he can use levofloxacin glucose injection to reduce inflammation, and it is recommended to apply it for about a week, and the patient’s condition should be significantly improved. Patients may experience adverse reactions during the medication period, such as stomach discomfort and tingling in the blood vessels, which occur promptly with feedback to the medical staff and active symptomatic treatment. However, it should be noted that levofloxacin is contraindicated in children, pregnant and nursing women, and should be used with caution in patients with reduced liver and kidney function.
