Warfarin dose schedule

Warfarin dosing is guided by clinical factors and pharmacogenomics. Despite evidence regarding the improvement in warfarin dosing with dose-calculation formulae, such as provided by http://warfarindosing.org , implementation of dosing guidelines can be challenging.

This webpage displays the possible dispensable weekly doses of warfarin to a user supplied goal weekly warfarin dose, and can be limited to a given warfarin pill strength. By default, the list is sorted such that the nearest doses are displayed at the top. Possible dispensable weekly doses are those that can be achieved with 0.5, 1, 1.5, or 2 pill increments of the same pill strength (e.g., a 5mg tablet).
