Clinical significance and safety
Doxepin and Xanax (Alprazolam): Other CNS depressants may increase the sedation caused by low-dose doxepin. Drowsiness, dizziness, reduced coordination and falls can be more likely. Driving and other hazardous tasks require particular caution when affected. The class warning does not mean that every combination is contraindicated or that each pair has been tested in a separate clinical trial. The cited doxepin evidence concerns 3 mg/6 mg insomnia tablets, not higher-dose antidepressant formulations. Ask a pharmacist or prescriber to review the full medicine list before adding or changing treatment.
