Prescription Eye Drop Size

“Smaller size drops, on the order of 15 microliters, have an efficacy and bioavailability equivalent to larger drops, without the waste.  In fact, drops of this size are preferable, as they minimize systemic exposure and wastage.” 1

-- J. Walt, Allergan, Inc. (eye drop manufacturer).

Pharmaceutical companies sell prescription eye drops in dispensers that emit drops that are much larger than the capacity of the eye to absorb.   As a result, much or most of these expensive medications go to waste, either by spilling out of the eye onto the patient’s cheek or draining through the tear duct into the nasal cavity and from there into the bloodstream.   

A wealth of medical and scientific literature over the past several decades shows that the wasted portion of the drops has no beneficial effect and that these larger eye drops are no more effective at treating patients’ diseases than smaller eye drops would be.   However, smaller eye drops would cost patients a lot less because patients could emit more drops from each bottle and the bottles would therefore last longer.  

The Law Office of Richard S. Cornfeld is representing consumers of prescription eye drops in two class actions to recover the amounts they and other consumers paid for these wasted drugs.   Plaintiffs allege that Defendants Alcon, Allergan, Bausch & Lomb, Merck, Pfizer, Prasco and Akorn committed deceptive and unfair practices in violation of state consumer protection statutes.   Click on this link to read the Amended Complaint in Eike et al. v. Allergan, Inc. et al., pending in the United States District Court for the Southern District of Illinois, and this link for the Complaint in Gustavsen et al. v. Alcon Laboratories, Inc., et al., pending in the United States District Court for the District of Massachusetts.
