Robotlove,
There is NO mention in the PI sheet for Xanax about blood thinning being a side effect. The statistics table showed a 1 - 5% chance of blood cell counts being affected, but no major effect.
It says that Xanax did NOT affect prothrombin times, which are related to clotting ability, nor did it alter Coumadin levels.
QUOTE
Further, alprazolam did not affect the prothrombin or
plasma warfarin (Coumadin) levels in male volunteers administered
sodium warfarin orally.
There are links to the Xanax PI sheet and website pinned above.
