A client with depression has been taking citalopram for several months and has presented for a follow-up assessment. The client tells the nurse, "I've been reading a lot online about the benefits of St. John's wort for depression, so I've started taking it once per day." In addition to referring the client to the provider, what is the nurse's best response?
1."Herbal remedies often contain unknown doses of the desired ingredient, which can be dangerous."
2."It's very important that you not take the St. John's wort at the same time of day as your
antidepressant."
3."It's very important that you comply with your prescribed treatment."
4."There can be an unsafe reaction between your antidepressant and St. John's wort, which is why taking them both is discouraged."
