What is Nortriptyline used for?
Nortriptyline is a tricyclic antidepressant that acts on mood regulation and pain pathways. - Major depressive disorder: reduces depressive symptoms in adults. - Neuropathic pain: alleviates pain associated with diabetic peripheral neuropathy. - Migraine prophylaxis: decreases frequency of migraine attacks.
What are the side effects of Nortriptyline?
Nortriptyline may cause a range of adverse reactions, from mild to serious.
Common Side Effects: - Dry mouth: reduced salivary flow causing throat discomfort. - Constipation: slowed gastrointestinal motility. - Drowsiness: increased sedation, especially after dose initiation. - Weight gain: gradual increase in body weight. - Blurred vision: temporary visual disturbances. - Urinary retention: difficulty initiating urination.
Serious or Rare Side Effects: - Cardiac arrhythmia: irregular heart rhythm, potentially life‑threatening. - Seizures: risk of convulsive episodes, especially at high plasma levels. - Severe hypotension: sudden drop in blood pressure causing dizziness. - Agranulocytosis: marked reduction in white blood cells. - Suicidal thoughts: emergence or worsening of suicidal ideation. - Serotonin syndrome: potentially fatal condition when combined with serotonergic agents.
What precautions apply to Nortriptyline?
Before prescribing nortriptyline, clinicians should consider several safety measures. - Assess cardiac history: obtain baseline ECG and monitor for arrhythmias. - Monitor for suicidal ideation: especially during the first weeks of therapy. - Avoid abrupt discontinuation: taper dose under medical supervision to prevent withdrawal. - Use caution in elderly: increased susceptibility to anticholinergic effects and falls. - Store at below 25°C: keep in the original pack, protect from moisture.
What does Nortriptyline interact with?
Nortriptyline interacts with several drug classes; careful review is required.
Major Interactions (Avoid): - MAO inhibitors: concurrent use can precipitate hypertensive crisis. - SSRIs or SNRIs: combined therapy raises risk of serotonin syndrome. - CYP2D6 inhibitors (e.g., fluoxetine): may increase nortriptyline plasma concentrations.
Moderate Interactions (Monitor Closely): - CNS depressants (e.g., benzodiazepines): additive sedation and respiratory depression. - Antihypertensives: potential for exaggerated hypotensive effect. - Alcohol: enhances drowsiness and impairs coordination.
