I went and saw Dr. Katz at Rush Hospital here in Chicago, the other day. He is suppose to be one of the best docs in the Fibro world. Anyway, he prescribed me Darvon - instead of the Darvocet that I was taking. When I went to Walgreens to fill the prescibtion - they said they can not fill Darvon scripts anymore. They called the Dr.'s office to see if they could give me Darvocet instead - which they did ok, but, he said I would not be able to fill the Darvon anywhere else anyway. What gives? The pharm. guy said there is a hold on pure Darvon, pure Vicdion, pure Oxycotin ect....Anyone else run into this trouble?
