US FDA panel says popular decongestant used in cold medicines ineffective
Sept 12 (Reuters) - An outside panel of experts to the U.S. Food and Drug Administration on Tuesday refused to back the effectiveness of oral over-the-counter (OTC) medicines made with phenylephrine, an ingredient widely used in cold and cough syrups. The panel unanimously voted against the effectiveness of orally administered phenylephrine as a nasal decongestant, adding that no more trials were required to prove otherwise. The panel vote could lead to the removal of oral phenylephrine, which is a major component of popular products like Benadryl, Advil and Tylenol, from the FDA's list of approved OTC ingredients, barring its sale in the United States. The FDA usually follows the recommendations of its expert panel but is not obligated to do so.
