Off-Label Drug Use [posted 8/11/98]
Question: Has the drug hydroxychloroquine sulfate (Plaquenil) been
tested for its activity against viral syndromes like HIV
disease? HIV patients have told me that it has measurably
improved their condition (doubled CD4+ T- cell counts – from
350 cells/mm^3 to 600+ cells/mm^3) for over one year. Where
should I look for possible trials of this drug against
HIV? Would its manufacturer (Sanofi Winthrop) keep records
of all trials of their products?
Answer: I really don’t keep up with new experimental treatments in HIV since that is a full time job and I use ID specialists for input as I need it. However, I would check (or have your physician check) with the scientific department of Sanofi: 800-446-6267.
Off Label Use
Question: Where do physicians find information on off-label uses of FDA approved products and experimental drugs?
Where do consumers/patients find the same?
Answer: Physicians use drugs for unapproved uses by understanding the pharmacology of the drug
and the purpose for which they intend it. There are many examples of physicians using drugs
for unapproved uses. For a company to get a use approved takes many studies and lots of
time and money. Physicians are not bound by these rules. Understanding a drug and its side
effects will predict whether it will have a use which is “unapproved”.
