Most seasonal throat infections are viral, meaning antibiotics like Levofloxacin will not help. Levofloxacin is a strong antibiotic reserved for specific bacterial infections and should only be taken under medical supervision. Self-medicating can lead to unwanted side effects or resistance. For a confirmed bacterial infection, the typical adult dose is 500 mg once daily for 5 to 10 days, as directed by a doctor. You do not need to take other antibiotics with it. To relieve throat pain, you can use supportive medications like paracetamol or ibuprofen. Please consult a doctor to get a proper diagnosis before taking this medication.
