Reduced trazodone concentrations with CYP3A4 inducers such as carbamazepine. Increased risk of excessive hypotension and hepatotoxicity with phenothiazines. Decreased anticoagulant effect of warfarin. Increased digoxin or phenytoin levels with trazodone. Increased risk of neurotoxicity, serotonin syndrome with lithium. Sedative effect enhanced by alcohol and other CNS depressants (sedatives, hypnotics, antihistamines, opioid analgesics).

Mechanism of Action
