(AP) – CVS Health is pulling from its drugstore shelves some cough-and-cold treatments that contain an ingredient that has been deemed ineffective by doctors and researchers.

The company said it will remove a small number of products that contain phenylephrine as the only active ingredient. CVS also said it will still sell “many other oral cough and cold products to meet consumer needs.”

A company spokeswoman declined to elaborate on how many products will be removed. CVS Health runs more than 9,000 stores.

Representatives of its national rival, Walgreens, did not immediately respond to a request for comment from The Associated Press.
