Average Rating

 Rating Answer: #30 Warfarin Tablets will last 35 DAYS at these directions... by: David The best way to arrive at an answer for this question is to start with how many tablets will be used in 1 week, and then move on from there. So the patient is taking 1 whole tablet on 5 total days each week, and taking 1/2 tab on 2 days each week. This second part: 1/2 tab on 2 days/week = 1 tablet/2 days. Add them together, 5 tablets (5 days) PLUS 1 tablet (2 days) EQUALS 6 Tablets in 7 days. The above question includes the fact that there is #30 tablets. We divide 6 tablets (which will each last 7 days) into 30 total tablets, and we come up with 5. So now, we multiply 5 times 7, and we come up with 35. #30 Warfarin (Coumadin) tablets, with DIRECTIONS of 1 whole tablet by mouth 5 times weekly and 1/2 tablet by mouth twice weekly, WILL LAST a total of 35 DAYS.

 Rating Days Supply for warfarin = 35 Days in this Example by: David 1 tab qd except monday and friday. (5 tabs) 1/2 tab on monday and friday (2 half tabs = 1 tab) So 6 tabs lasts 7 days. #30 tabs will last 5 weeks (6/30=5) 5x7=35 days
