Can 5-htp (100mg) be used safely with 7.g per day of buspirone? just came off of 20 mg citalopram 2 weeks ago.

Drug interaction: I hope you are asking about 7 mg of buspirone, not 7 grams. Buspirone usually is dispensed as 7.5 mg to 30 mg/ day. 5-HTP is usually a safe dose to be taken daily, however the interaction between 5 HTP and buspirone can cause nausea. Ask the prescriber of the buspirone whether they think you should be taking these two meds together.
