Nortriptyline
Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Prescription tricyclic antidepressant (TCA) approved for major depressive disorder. The active metabolite of amitriptyline with a more favorable side effect profile, including less sedation and anticholinergic burden. Commonly used for neuropathic pain and migraine prophylaxis. Has a well-defined therapeutic window (50–150 ng/mL serum levels) and is better tolerated than amitriptyline, making it the preferred TCA in many clinical settings. Dosage must be determined by your prescribing physician.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Prescription tricyclic antidepressant (TCA) approved for major depressive disorder. NutriStack rates the supporting evidence as strong. Common adult dosing is 25–150 mg daily (as prescribed by your physician), though a prescriber sets the actual dose. With long-term use it can deplete sodium. This profile indexes 10 sources.
The bottom line
Evidence rating strong. Most-documented uses: depression symptom relief, neuropathic pain relief, migraine prophylaxis. 10 sources indexed (1994–2026), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Primarily inhibits the reuptake of norepinephrine (NET blockade) with secondary serotonin reuptake inhibition (SERT blockade). Compared to amitriptyline, has greater NET selectivity and reduced antihistaminic, anticholinergic, and alpha-1 adrenergic antagonism, contributing to its improved tolerability.
Dosing & protocol.
Can be taken with or without food. May be taken at bedtime to minimize daytime sedation. Therapeutic drug monitoring available (target 50–150 ng/mL).
What it depletes.
Nutrients this medication can lower over time, and what to replace.
Sodium
ModerateAntidepressant-associated SIADH can increase renal free-water retention and dilute serum sodium, producing hyponatremia.
