The U.S. Food and Drug Administration (FDA) is overseeing a nationwide recall of millions of bottles of prescription eye drops used to treat eye inflammation and allergies. Multiple outlets report that the recall is triggered by the possible presence of a foreign substance in the product. According to the FDA-referenced reporting, more than 2.5 million bottles are included in the action. The recall involves eye drop bottles in multiple sizes. The products are linked to manufacturing by Lupin Limited in India, as described by the sources. The medications are described as being used to relieve irritation and allergic symptoms as well as inflammation in the eye. The recall is characterized as a contamination-related precaution, with the foreign substance described as “possible,” rather than confirmed. The reporting indicates the recall is being implemented across the country.
