b. "It is safe to take St. John's wort with prescription antidepressants."
c. "St. John's wort does not affect nutrition."
d. "You should take St. John's wort as needed when symptoms occur."
ANS: A
St. John's wort can cause photosensitivity, so patients should be counseled to use sunscreen. It should not be taken with prescription antidepressants because it increases the risk of suicidal ideation. It interferes with the absorption of iron and other minerals. Effects do not occur for 4 to 8 weeks, so it cannot be taken as needed.
