Miebo™ Eye Drops – What is the Days’ Supply?
Miebo™ is the first and only prescription eye drop used to treat dry eye syndrome by directly targeting tear evaporation. PAAS National® has fielded several calls regarding Miebo™ asking how to calculate the days’ supply. Per DailyMed, Miebo™ comes in a package size of 3 mL. Section 16 of the package insert states it is supplied in a multi-dose 5 mL bottle. Which measurement, 3 mL, or 5 mL, should you use to calculate the days’ supply? Miebo™ is billed as 3 mL; there are 3 mL of active ingredient in a 5 mL multi-dose bottle, presumptively to make administration easier. However, based on information from the Bausch + Lomb website, the days’ supply calculation remains complicated. Miebo™ contains only one ingredient (perfluorohexyloctane), unlike other eye drops that contain water, preservatives, and steroids. Eye drop formulations with water have a typical drop size of 30 to 50 microliters. The Miebo™ drop size is much smaller at 11 microliters, causing problems with the traditional 15 to 20 drops per mL estimate.
PAAS Tips:
- Pharmacies should NOT use PBM provided drops/mL when calculating the days’ supply for Miebo™
- After opening, Miebo™ can be used until the expiration date on the bottle.
