The U.S. Food and Drug Administration (FDA) is overseeing a nationwide recall of millions of bottles of prescription eye drops used to treat allergies and eye inflammation, according to multiple reports. The FDA says the recall is prompted by concerns that a foreign substance may be present in the product. The recalled medication is manufactured by Lupin Limited in India and is supplied in multiple bottle sizes. Media outlets report the recall involves more than 2.5 million bottles. The products are described as eye drops prescribed for conditions including irritation, allergies, and inflammation, including inflammation that can occur after surgery. The New York Times and other sources characterize the contamination issue as a potential foreign substance problem rather than a confirmed harmful ingredient, and describe the recall as a preventive action by the FDA. The reports do not specify the exact substance or provide further details in the provided excerpts about lot numbers or distribution, but they consistently link the recall to the FDA’s warning and the potential contamination concern.
