Myth No. 5: Health care professionals don’t need to know what vitamins patients take.
Nearly 63% of US adults take 1 or more vitamins or dietary supplements, and many perceive them to be risk-free and “natural” without any potential for adverse effects, results from a 2012 survey revealed.
 
Health care professionals should make sure they are asking patients about any vitamins they may be taking, so that they can warn these patients about potential drug-vitamin interactions.
 
Examples of vitamins with the potential for serious interactions include vitamins A and E, which increase the effects of anticoagulation and should therefore be closely monitored when taking warfarin, and magnesium, which can decrease antibiotic absorption and should be dosed separately by 2 hours before or 6 hours after taking an antibiotic.
