For a four-week course of azithromycin eye ointment applied three times daily, you will typically need two tubes (assuming standard 3g or 5g tubes). A single application uses a tiny ribbon (about 1 cm), which is roughly 0.05 grams. Over 28 days, you will apply it 84 times, requiring approximately 4 to 5 grams in total. To ensure you do not run out and to account for any minor wastage during application, purchasing two tubes is the safest approach. Always store them as directed and discard any leftover ointment after completing your treatment.
