Marketing Missive: FDA Issues Warning Letter to Procter and Gamble for Unlawfully Marketing Cold and Flu Medications Containing Vitamin C
By Guest Blogger Tyler Anderson
On October 29, 2009, the FDA issued a warning letter to Procter and Gamble notifying the company that its “Vicks DayQuil Plus Vitamin C” and “Vicks NyQuil Plus Vitamin C” are illegally marketed combinations of drug ingredients and a dietary ingredient. Both of the over-the-counter (OTC) medicines, which contain Vitamin C in addition to several drug ingredients, are marketed as treatments for cold and flu symptoms. The FDA issued the warning letter (1) to clarify that these single dosage form combinations of drug ingredients and dietary ingredients cannot legally be marketed because they have not been proven safe and effective, and (2) because the agency has previously determined that there is not sufficient data to show that Vitamin C is safe and effective in preventing or treating the common cold.
Under its OTC monograph system, the FDA allows some OTC drugs to be marketed without agency approval. The FDA found the two Vicks products did not comply with the applicable FDA monograph, and therefore the products must first be evaluated and approved under the agency’s new drug approval process before they can be legally marketed.
