Latanoprost ophthalmic solution is dispensed to a patient with glaucoma. What are the correct storage directions?
a.Refrigerate the unopened bottle at 2-8 °C; once opened it may be kept at room temperature for up to 6 weeks
b.Freeze the bottle until the first dose is due
c.Store at room temperature indefinitely with no expiration limit after opening
d.Keep the bottle in direct sunlight to maintain clarity
Explanation
Unopened latanoprost requires refrigeration at 2-8 °C, and after the bottle is opened it may be stored at room temperature for up to 6 weeks. Freezing is never appropriate for ophthalmic solutions, an opened bottle does have a limited beyond-use period, and light exposure degrades the drug.
