About Nortriptyline
Indications of Nortriptyline
Nortriptyline is a tricyclic antidepressant (TCA) with the following evidence-based uses:
Established / approved use
- Major depressive disorder (endogenous depression) in adults — Nortriptyline is indicated for the relief of symptoms of depression.
Guideline-supported / commonly used off-label
- Chronic neuropathic pain (e.g. diabetic peripheral neuropathy, post-herpetic neuralgia) — Nortriptyline is widely recommended in pain-management guidelines as a second/third-line agent, generally after first trying agents with a more favourable safety profile.
- Migraine prophylaxis — used off-label to reduce the frequency of migraine and chronic tension-type headache.
- Fibromyalgia-related pain — used off-label, sometimes as an adjunct to other therapies.
Use of Nortriptyline for any indication should be initiated and supervised by a qualified physician, who will weigh the potential benefit against the risks described under Precautions and Warnings.
Dosage & Administration of Nortriptyline
Depression (adults)
| Population | Typical starting dose | Usual maintenance dose | Maximum dose |
|---|---|---|---|
| Adults | 25 mg 3–4 times daily (or 25 mg at bedtime, titrated) | 50–150 mg/day, in divided doses or once daily | 150 mg/day |
| Adolescents and elderly patients | 10 mg 3 times daily (or 25–50 mg total per day) | 30–50 mg/day | As advised by physician; lower than adult maximum |
Chronic neuropathic pain / migraine prophylaxis (off-label)
Typically started at a low dose (e.g. 10–25 mg at bedtime) and titrated gradually every 3–7 days according to response and tolerability, up to 75–100 mg/day in some patients, under close physician supervision. See Duration of Treatment.
Administration
Nortriptyline may be taken with or without food. Taking it at bedtime can help reduce daytime sedation. Doses should not be adjusted, stopped abruptly, or shared with others without medical advice — discontinuation should be tapered gradually under physician guidance to reduce the risk of withdrawal symptoms.
Renal/hepatic impairment
No formal, well-established dose-adjustment schedule exists for renal or hepatic impairment; however, because Nortriptyline is hepatically metabolised, physicians typically start at a lower dose and titrate slowly with closer monitoring in patients with hepatic impairment.
Side Effects of Nortriptyline
Common
- Dry mouth, constipation, blurred vision, urinary hesitancy/retention (anticholinergic effects)
- Drowsiness, dizziness, weakness
- Orthostatic (postural) hypotension
- Weight gain, increased appetite

Serious (seek medical attention promptly)
- Cardiac arrhythmias, palpitations, QT prolongation (see Precautions and Warnings)

- Worsening depression, unusual changes in behaviour, or suicidal thoughts (see Precautions and Warnings)
- Serotonin syndrome (agitation, high fever, muscle rigidity, rapid heart rate) when combined with serotonergic drugs
- Signs of hyponatremia/SIADH (confusion, severe weakness, headache), particularly in elderly patients
- Severe allergic reaction (rash, swelling, difficulty breathing)
Contraindications of Nortriptyline
- Known hypersensitivity to Nortriptyline or other tricyclic antidepressants.
- Concomitant use of, or use within 14 days of discontinuing, a monoamine oxidase inhibitor (MAOI).
- Acute recovery phase following myocardial infarction (heart attack).
Frequently Asked Questions about Nortriptyline
What is Nortriptyline used for?
Nortriptyline is a tricyclic antidepressant approved for treating depression in adults. It is also commonly used off-label, under physician supervision, for chronic neuropathic pain and to help prevent migraine headaches.
How long does it take for Nortriptyline to work?
For depression, it can take 4–6 weeks of regular use at an adequate dose to see the full antidepressant effect, although some improvement in sleep or pain may be noticed sooner. Do not stop taking Nortriptyline early just because you don't feel a difference right away — discuss any concerns with your physician.
Can I stop taking Nortriptyline suddenly?
No. Stopping Nortriptyline abruptly after regular use can cause withdrawal-type symptoms such as nausea, headache, and malaise. Your physician will usually taper the dose gradually when it is time to stop.
Is Nortriptyline safe during pregnancy or breastfeeding?
Nortriptyline should be used in pregnancy only if clearly needed, since third-trimester exposure has been linked to transient symptoms in newborns such as irritability and feeding difficulty. In breastfeeding, Nortriptyline passes into breast milk in relatively small amounts and is one of the more commonly used tricyclic antidepressants in nursing mothers, but a physician should always be consulted first and the infant monitored for sedation or feeding problems.
What are the serious risks I should know about with Nortriptyline?
Nortriptyline carries a boxed warning for increased risk of suicidal thoughts and behaviour in children, adolescents, and young adults, especially early in treatment. It can also affect heart rhythm (QT prolongation, arrhythmias), so a heart tracing (ECG) may be recommended before starting, particularly in older adults or those with heart disease. Overdose with Nortriptyline can be life-threatening due to effects on the heart, so it should be kept out of reach of children and taken exactly as prescribed.
What should I do if someone takes too much Nortriptyline?
An overdose of Nortriptyline is a medical emergency that can cause dangerous heart rhythm problems, seizures, and loss of consciousness. Seek immediate medical attention or contact emergency services / a poison control center right away — do not wait for symptoms to appear or try to treat it at home.
