Nortriptyline is a tricyclic antidepressant that modulates neurotransmitter pathways involved in mood and pain perception.

- Major depressive disorder: alleviates depressive symptoms and improves mood in adults. - Neuropathic pain: reduces pain intensity associated with peripheral neuropathy. - Migraine prophylaxis: decreases frequency and severity of migraine attacks. - Anxiety disorders: helps control symptoms of generalized anxiety and related conditions.

Nortriptyline may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Dry mouth: reduced salivation causing discomfort. - Drowsiness: increased sedation or fatigue. - Constipation: slowed gastrointestinal motility. - Blurred vision: temporary visual disturbances. - Weight gain: increased appetite leading to weight increase.

Serious or Rare Side Effects: - Cardiac arrhythmia: irregular heart rhythm that may be life‑threatening. - Seizures: risk of convulsive episodes, especially at high doses. - Severe hypotension: marked drop in blood pressure causing dizziness or fainting.

Before prescribing nortriptyline, clinicians should consider several safety precautions to minimize risk.

- Assess cardiac history: evaluate for conduction abnormalities or arrhythmias. - Review concomitant medications: avoid drugs that prolong QT interval. - Monitor for suicidal ideation: especially during initial treatment phases. - Caution in elderly patients: increased sensitivity to anticholinergic effects. - Evaluate liver and kidney function: adjust dosing if impairment is present. - Store at ambient temperature: keep below 25°C in original packaging, protect from moisture.

Nortriptyline interacts with several medicines; awareness of major and moderate interactions helps prevent adverse outcomes.

Major Interactions (Avoid): - MAO inhibitors: risk of hypertensive crisis or serotonin syndrome. - SSRIs or SNRIs: increased serotonin levels may cause serotonin syndrome. - Anticholinergic agents: additive anticholinergic burden leading to severe side effects.

Moderate Interactions (Monitor Closely): - CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may raise nortriptyline plasma levels. - CNS depressants (e.g., alcohol, benzodiazepines): enhanced sedation and respiratory depression. - Diuretics: may potentiate orthostatic hypotension.
