The article entitled "Homeopathic vs Conventional Treatment of Vertigo,"1 published in the 1998 issue of the ARCHIVES compared a homeopathic product, Vertigoheel, with the compound betahistine hydrochloride. Betahistine was formerly marketed in the United States as Serc (Unimed Corp, Morristown, NJ), and was removed from the market by the Food and Drug Administration (FDA) in 1968 for lack of proof of effectiveness and because the major report of effectiveness contained deficiencies and misrepresentations. The manufacturer contested FDA action in the courts, but the Court of Appeals, Second District, upheld the FDA action in 1972. Betahistine has not been marketed in the United States since then. I have that information, obtained under the Freedom of Information Act.
