More than 3.1 million bottles of eye drops sold at major retailers, including Walgreens and CVS, are being recalled due to concerns about their sterility, according to a notice from the Food and Drug Administration.

The eyedrops have been recalled by their manufacturer, K.C. Pharmaceuticals, according to the March 3 alert. The products were sold under a number of brand names, including Dry Eye Relief Eye Drops and Artificial Tears Sterile Lubricant Eye Drops.

The recall was classified as "Class II" by the FDA, which describes products that may cause "temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote." Another major eye drops recall in 2023 involved a different manufacturer whose products may have contained bacteria.

The latest eye drops recall involves eight brands manufactured by K.C. Pharmaceuticals, with the largest lot involving more than 1 million bottles sold under the Dry Eye Relief Eye Drops brand at stores including Rite Aid, H-E-B and Harris Teeter.
