Abstract
The need to maintain long-term treatment of chronic pathologies makes the appearance
of interactions possible when such therapies incorporate other drugs to deal with
the aggravation of the same or other intercurrent pathologies. A case is presented
in which the addition of trazodone to a chronic treatment with carbamazepine (CBZ)
is associated with symptoms typical for intoxication by this antiepileptic, accompanied
by a raised serum concentration. When the trazodone was suspended, these symptoms
lessened and the concentration of CBZ decreased progressively, suggesting a probable
interaction between the 2 drugs.
Key words
carbamazepine - trazodone - drug interaction
