I hurt my shoulder a few days ago and my doctor gave me tylenol 3 for the pain. I take citalopram, and trazodone, and he prescribed the tylenol so that I shouldn't have any interactions. I take trazodone for sleep, if i take the tylenol 3 at night with the trazodone will that cause problems or should I take the tylenol before I take the trazodone at bedtime? Any advice would help, thanks. :)
