Over-the-counter ophthalmic products were voluntarily recalled due to a manufacturing deviation discovered during a U.S. Food and Drug Administration audit, a notice says.

Millions of cartons of eye drops and other eye products have been recalled nationwide due to manufacturing and quality issues. The company AvKARE issued the voluntary recall after issues were identified during an audit by the Food and Drug Administration (FDA). About 1.8 million cartons of eye drops were recalled, according to the FDA.

The products in question were shipped out up until recently. The distributor recommends that further use of the products "should immediately cease."
