Sudafed and other common nasal decongestants containing pseudoephedrine are on display behind the counter at Hospital Discount Pharmacy in Edmond, Okla., Jan. 11, 2005. On Tuesday, Sept. 12, 2023, advisers to the Food and Drug Administration said that a different ingredient, phenylephrine, is ineffective at relieving nasal congestion. Drugmakers reformulated their products with phenylephrine after a 2006 law required pseudoephedrine-containing medications to be sold from behind the pharmacy counter. (AP Photo) **FILE**
