A TIKOSYN SHORTAGE. “Pfizer is writing to inform you of a shortage of 60 count bottles of TIKOSYN® 250 mcg and 500 mcg. . . . This product shortage is a result of a manufacturing issue and not the result of any efficacy or safety issues with TIKOSYN®. Pfizer is working as quickly as possible to resolve the situation.” This is already causing problems for the Insta-Wife, who needs Tikosyn to live.
