What it means

An older antidepressant that raises norepinephrine and serotonin. It is used for depression and, short term, for bedwetting (nocturnal enuresis) in children aged 6 and older. It has strong anticholinergic effects (dry mouth, constipation, urinary retention, blurred vision), causes drowsiness and low blood pressure on standing, and an overdose can cause deadly heart rhythms and seizures.

For the nurse

Give it at bedtime. Assess suicide risk and give only limited amounts at a time to clients at risk, since overdose is very dangerous. Teach the client to rise slowly. The Beers Criteria advise avoiding it in older adults.
