What is the dosage and duration of cipro (ciprofloxacin) for sinus infection?

10days: Cipro (ciprofloxacin) 500 mg taking every 12 hours for 10days. For sinus infection.

500mg 2x/day x10days: The usual Cipro (ciprofloxacin) dosage is 500mg 2x/day for about 10 days. It is not the most common/first choice for sinusitis, but it should work. Sinusitis often occurs because of not promptly treating the common cold or uncontrolled allergies which cause swelling inside your nose thus blocking sinus openings. So, treat the cold/allergies adequately and u may not need Cipro (ciprofloxacin) at all. Consult doc. Good luck.

It depends.: For the average size adult without kidney or liver problems, the appropriate dose for an acute sinus infection (symptoms present for only a week or so) is 500mg twice a day for 7 to 10 days. Chronic sinusitis (infection persisting for several weeks or more) is often treated for much longer, up to 4-6 weeks of antibiotic therapy.
