In reply to Question For Cam W. Re: Brand Name Stelazine, posted by Michael F on March 1, 2001, at 22:33:50
Michael - Generic companies, many of which are subsidiaries of brand-name companies, are required by law (in Canada) to have pharmacokinetic patterns within 5% of the brand name drug. Lots are teated for this. I have heard of the problem that you are talking about more frequently with Valium over generics (but hesitate as to a lack of efficacy explanation, because brand name Valium can be sold for a higher price in the street).
Another explanation for the lack of efficacy of the tablets is that they could have been nearing expiry date. If it continues, ask the drug store to bring in a different brand of Stelazine generic. I have never had a problem with the Apotex brand.
I do not know the US's requirements for generic drugs, though.
Hope this helps - Cam
