Bayer is recalling a portion of its popular Alka-Seltzer Plus line of cold and flu relief products after it was discovered that ingredients in the medication may not match those listed on the package. Additionally, ingredients listed on a sticker on the front of the box may differ from those printed on the back of the carton.

The products were sold after February 9, 2018, in the United States at Walmart, CVS, Walgreens and Kroger stores. Kroger brands include King Soopers, Dillons Food Stores, Fred Meyer, Fry’s Food Stores, Ralphs, and Smith’s Food and Drug.

Affected packages have the Bayer logo on the front of the carton with an orange or green background. Bayer recommends that consumers who purchased the recalled product should stop using it immediately and call 800-986-0369 if they have questions. The line is available Monday through Friday between 9:00 a.m. and 5:00 p.m. Eastern Time. Anyone who has experienced problems after using the product should see a doctor.

Some people could experience allergic reactions after using the product, or it may interact with other medications, resulting in serious health issues. So far, the company has not received any complaints about unexpected health effects.
