Standard Dosage for Adult Sinus Infections

For adults treating acute bacterial sinusitis, the typical Zithromax (azithromycin) dosage is 500 mg on the first day, followed by 250 mg daily for four days. This amounts to a total of 1.5 grams of azithromycin over five days.

Alternative Dosage Regimen

A different regimen involves taking 250 mg once daily for five days. Always follow your doctor’s prescription precisely. Do not adjust the dosage yourself. This information is for guidance only and does not substitute professional medical advice.

Remember to finish the entire course of medication, even if you start feeling better before the prescribed treatment ends. This prevents recurrence of the infection. Contact your healthcare provider if symptoms worsen or persist beyond the expected timeframe.
