Interactions with Herbs

Digitalis (Digitalis lanata, Digitalis purpurea)
Digitalis refers to a family of plants commonly called foxglove that contain digitalis glycosides, chemicals with actions and toxicities similar to the prescription drug digoxin.

Trazodone was associated with increased serum digoxin levels in one case report.1 No interactions between trazodone and digitalis have been reported. Until more is known, trazodone and digitalis-containing products should be used only under the direct supervision of a doctor trained in their use.

Ginkgo biloba
There is one case report of an elderly patient with Alzheimer’s disease going into a coma while concurrently using trazodone and ginkgo.2 Until more is known, ginkgo should not be combined with trazodone except under supervision of a doctor.

St. John’s wort (Hypericum perforatum)
One report described a case of serotonin syndrome in a patient who took St. John’s wort and trazodone.3 The patient reportedly experienced mental confusion, muscle twitching, sweating, flushing, and ataxia. Until more is known, St. John’s wort should not be combined with trazodone except under expert clinical supervision.

Interactions with Foods and Other Compounds

Food
Trazodone should be taken with food.4

Alcohol
Trazodone may cause drowsiness or dizziness.5 Alcohol may compound these effects and increase the risk of accidental injury. To prevent problems, people taking trazodone should avoid alcohol.
