question: Hello doctor,I have just had a sinus lift graft and implants placed. The dentist has prescribed 500 mg of Levofloxacin every 12 hours for 10 days, plus Augmentin, plus Ibuprofen and Dexamethasone. My question is whether the Levofloxacin is necessary and why is it such a high dose? I have read it should not be taken with Ibuprofen and Dexamethasone. My dentist said it is fine, but I am very worried as I have heard this antibiotic is very toxic. What is your advice concerning this issue, please?
