Trazadone was the third in a line of 'depression' meds prescribed for me because the rheumatologist had no idea where to begin with my odd symptoms (this was pre RSD diagnosis by a pain doctor). Pristiq made me break out in hives, and both Elavil and Trazadone just made my skin burn more. Trazadone did nothing for my pain, it just aggravated my symptoms.

Don't know if this helps at all.

Good luck to your daughter.
