Lawmakers Press Califf on OTC Decongestant
Despite pharmaceutical researchers' skepticism for decades on the effectiveness of over-the-counter (OTC) drugs that contained the decongestant phenylephrine, why did it take FDA so long to finally consider withdrawing the products? This is the question the House Oversight Committee’s Subcommittee on Health Care and Financial Services wants FDA commissioner Robert Califf to answer in a requested staff-level briefing.
The lawmakers are reacting to FDA’s Nonprescription Drugs Advisory Committee recent vote (16 to 0) that current scientific data do not support the effectiveness of the over-the-counter monograph dosage of orally administered phenylephrine (10mg) as a nasal decongestant (see earlier story). Phenylephrine is the active ingredient found in a number of common OTC cold and allergy treatments, such as Sudafed PE and Benadryl Allergy Plus Congestion.
“We are concerned that phenylephrine has remained approved by the Food and Drug Administration (FDA) as an OTC drug ‘generally recognized as safe and effective’ (GRASE) for nearly fifty years despite strong scientific evidence supporting the contrary,” the subcommittee said in a 12/3 letter to Califf.
The subcommittee noted that for many years “scientific support for the effectiveness of phenylephrine has been consistently weak, showing that the drug administered orally provides no better symptom relief than a placebo.” The subcommittee further said it was “concerning” that FDA “relied upon outdated and insufficient evidence regarding phenylephrine’s use as a decongestant for so many years, despite numerous appeals by the scientific community. Americans seeking OTC relief should not have to worry whether they are wasting their hard-earned money on ineffective drugs.”
