What is the storage guideline for Azithromycin suspension after reconstitution?

• A. Store for 10 days in the fridge or at room temperature once reconstituted.
• B. Store for 30 days in the freezer.
• C. Store indefinitely at room temperature.
• D. Discard after 5 days.

Answer: (A)

Post-reconstitution shelf-life and storage conditions for liquids are about how long the liquid form remains stable and safe to use. Azithromycin suspension, once prepared, is generally stable for about 10 days. It can be kept either in the refrigerator or at room temperature during that window, as long as it’s kept in its original bottle, tightly closed, and away from heat and light. Refrigeration helps preserve potency, while room temperature storage is acceptable for the same 10-day period if conditions are cool and dry.

Avoid freezing the suspension, since freezing can alter texture and potency. Do not assume it lasts indefinitely at room temperature—the product can degrade and risk of microbial growth increases over time. Also note that 5 days would be too short given the standard guidance, and discard if it looks off or has passed the 10-day limit. Always follow the label specifics for storage and discard guidance.
