Phenylephrine, a key element in cold and allergy medication, is ineffective in relieving nasal congestion, the United States Food and Drug Administration, said on Tuesday, 12 September.
Phenylephrine – a popular ingredient found in most over-the-counter drugs such as Vicks Nyquil, Benadryl, and Sudafed – generated almost USD 1.8 billion in sales revenue in 2022, the FDA said.
What the advisory committee found: Up until now, it was thought that Phenylephrine helps in decongestion by reducing the swelling of the blood vessels.
But the advisory panel found that it is ineffective, because when it is consumed orally, the quantity that actually reaches your nose is minimal.
