Tricyclic antidepressant is a type of drug that is widely prescribed for depression.
Tricyclics are usually administered by mouth. Side effects may include sedation, blurred vision, sweating, constipation, and urinary hesitancy. They are highly toxic if taken in overdose. Seizures and hallucinations are possible, especially in elderly patients with organic brain disease. Side effects are most acute during the first 10 to 15 days of treatment.
