Nortriptyline Flamingo Pharma Uk (Nortriptyline)

Nortriptyline, a tricyclic antidepressant, is used to treat several conditions affecting mood, pain perception, and vascular headache mechanisms.

• Major depressive disorder: alleviates depressive symptoms and improves mood in adult patients.
• Neuropathic pain: reduces pain intensity and improves functional capacity in chronic nerve‑damage conditions.
• Migraine prophylaxis: decreases frequency and severity of migraine attacks when used as a preventive therapy.

• Nortriptyline inhibits the reuptake of norepinephrine and serotonin, increasing their synaptic concentrations. It also antagonizes muscarinic acetylcholine, histamine H1, and α1‑adrenergic receptors, contributing to its analgesic, antidepressant, and anti‑migraine effects through modulation of central neurotransmission and peripheral vascular tone.

Common Side Effects

• Dry mouth: reduced salivary flow leading to a persistent dry sensation.
• Constipation: slowed gastrointestinal motility causing infrequent, hard stools.
• Drowsiness: sedation or increased sleepiness, especially at treatment initiation.
• Weight gain: increased appetite and gradual weight increase.

Serious or Rare Side Effects

• Cardiac arrhythmia: irregular heart rhythms that may be life‑threatening.
• Seizures: heightened risk of convulsive episodes, particularly in predisposed individuals.
• Severe hypotension: sudden drop in blood pressure causing dizziness or fainting.
• Serotonin syndrome: potentially fatal condition when combined with other serotonergic agents.
• Agranulocytosis: marked reduction in white blood cells, increasing infection risk.
• Suicidal thoughts: emergence or worsening of suicidal ideation, especially early in therapy.

Before prescribing nortriptyline, clinicians should consider several safety factors.

• Cardiac assessment: obtain baseline ECG and monitor for conduction abnormalities.
• History of seizures: evaluate risk and use the lowest effective dose.
• Concomitant antidepressants: avoid combining with other serotonergic drugs without specialist input.
• Elderly patients: start at low dose and monitor for anticholinergic effects.
• Pregnancy and lactation: weigh potential benefits against unknown fetal risks.
• Store at ambient temperature: keep in the original container, protect from moisture and light.

Nortriptyline may interact with a range of medicines, requiring careful management.

Major Interactions (Avoid)

• MAO inhibitors: risk of hypertensive crisis and serotonin syndrome.
• SSRIs, SNRIs, or other serotonergic agents: increased serotonin toxicity.
• Linezolid or tramadol: heightened potential for serotonin syndrome.

Moderate Interactions (Monitor Closely)

• Antihypertensives: additive hypotensive effect, monitor blood pressure.
• Anticholinergic drugs: amplified anticholinergic burden, watch for severe dry mouth or urinary retention.
• CNS depressants (e.g., benzodiazepines, alcohol): enhanced sedation, adjust dosing as needed.
