What are side affects of taking half a trezedone and pregnant?

What are you taking : it for? depression, insomnia? and how many mgs? how long have you been taking it? or do you want to take it just this time. If that's the case, don't do it. When pregnant and depending on your trimester, be weary of putting extra meds in your body. If its absolutely not necessary don't do it. Trazodone is a cat. C drug: animal studies show adverse fetal effects but no controlled human studies
