The Mosby's Drug Guide reports a potential drug-drug
interaction with acetaminophen and warfarin. If a patient is
taking warfarin, more than 2 g/day of acetaminophen may
increase bleeding. Because Mr. Larsen is ordered both, he
should receive no more than 2 g/day of acetaminophen.
Question
If Mr. Larsen takes acetaminophen 325 mg 2 tabs by mouth
every 4 hours for mild pain, what is the maximum number of
tablets you can give him so that he doesn't exceed 2 g/day?
Assume you will only give him whole tablets.
