Does this over-the-counter decongestant actually work? FDA panel to re-evaluate phenylephrine


Does a standard ingredient utilized in many over-the-counter chilly and allergy medicines really work to eliminate nasal congestion?

That’s the query the Meals and Drug Administration will pose to a panel of outdoor advisers throughout a two-day assembly subsequent week to re-evaluate the effectiveness of the ingredient, phenylephrine, which is discovered in lots of decongestants. 

Phenylephrine was accepted by the FDA for over-the-counter use within the Seventies. It is available in a number of kinds, together with liquids, capsules and nasal sprays. 

The committee will focus particularly on the oral formulations of the ingredient, which will be present in medicine together with Sudafed PE, Vicks Sinex and Benadryl Allergy Plus Congestion.

The stakes are excessive, consultants say, as a result of a committee vote declaring phenylephrine ineffective as an oral decongestant might push the FDA to revoke the drug’s over-the-counter designation as “Usually Acknowledged as Protected and Efficient,” and doubtlessly result in it being pulled from shops cabinets. The designation, usually used for older medicine, permits drugmakers to incorporate an ingredient in over-the-counter merchandise with out the necessity to file an FDA utility.

Oral phenylephrine is ineffective and “ought to virtually by no means be used,” mentioned Dr. Purvi Parikh, an allergist and immunologist at Allergy & Bronchial asthma Associates of Murray Hill in New York Metropolis.

Dr. Wynne Armand, a major care doctor at Massachusetts Common Hospital, mentioned she doesn’t prescribe the drug.

“When my sufferers ask for over-the-counter drugs for chilly signs, I inform them to keep away from shopping for oral meds which have phenylephrine,” Armand mentioned.

Permitting folks to make use of such drugs is dangerous not simply because they don’t work, she added, however as a result of the medicine include negative effects together with headache, insomnia and nervousness.

The FDA already seems to have modified its place on the drug.

In briefing paperwork posted on-line Thursday, FDA scientists mentioned that though it has not discovered any questions of safety with oral phenylephrine, their evaluation of the info on the drug discovered that it’s not efficient as a nasal decongestant, even when given at excessive doses.

Questions in regards to the drug’s effectiveness go way back to 2007, when a gaggle of pharmacists filed a Citizen Petition to drag the drug from retailer cabinets due to proof that it was no higher than a placebo. 

The pharmacists cited research that discovered when taken orally, a big portion of phenylephrine is metabolized within the intestine and liver earlier than it reaches the bloodstream. Which means that a really small quantity of the drug really reaches the nostril to relieve congestion.

The FDA didn’t request that drugmakers pull the drug at the moment, and as an alternative requested for extra information, together with in regards to the drug at increased doses.

The Client Healthcare Merchandise Affiliation, a gaggle that represents over-the-counter drug producers, mentioned it’s towards eradicating oral phenylephrine from the market, including that it’s the solely broadly obtainable over-the-counter oral nasal decongestant.

“CHPA urges the panel to acknowledge PE’s clear advantages and demanding position in public well being,” Marcia Howard, the group’s vp of regulatory and scientific affairs, mentioned in a press release referring to phenylephrine. Eradicating the drug from the market might trigger folks to delay or forgo therapy, she mentioned.

Different oral decongestants can be found, although they are often much less accessible. Pseudoephedrine, present in Sudafed, is accessible with no prescription, however in 2006 it was moved behind the pharmacy counter to stop folks from shopping for giant portions of the drug, which can be utilized to make meth. Which means that individuals who need to purchase Sudafed have to ask a pharmacist for it. 

“Sudafed does work for just a few days, however not in the long term,” Parikh mentioned.

The FDA isn’t questioning the effectiveness of nasal spray phenylephrine.

Parikh mentioned that it might enhance signs briefly, however she suggested that folks use nasal spray phenylephrine just for a number of days. After that, it might develop into ineffective and have rebound results that make congestion worse.
