Nortriptyline
In brief
- Nortriptyline is a prescription-only medicine in the UK and is supplied by a pharmacy only on a valid prescription.
- Nortriptyline is used mainly to treat major depressive disorder, and it is also used off label for neuropathic pain, migraine prevention and sometimes fibromyalgia. It is a tricyclic antidepressant that works by blocking the reuptake of noradrenaline and serotonin, increasing their levels in the brain.
- The usual dose of nortriptyline depends on the condition: for depression, adults often start at 25 mg three or four times daily, with a typical maximum of 75–150 mg per day; for pain or migraine, treatment often starts at 10–25 mg at bedtime and is increased slowly as tolerated.
- Nortriptyline is taken by mouth as tablets or capsules.
- Nortriptyline usually starts to work within 2–4 weeks for depression, although some people may notice early changes sooner. For pain conditions, benefit may begin after 1–3 weeks.
- The duration of action is usually about 24 hours per dose, which is why it is often taken once daily at night for pain or in divided doses for depression. Full treatment courses may continue for months, especially after symptom improvement.
- Alcohol should be avoided or kept to a minimum, as it can increase drowsiness, dizziness and impaired thinking, and may worsen side effects and safety risks.
- The most common side effects are dry mouth, constipation, drowsiness, dizziness, blurred vision, weight gain, sweating and lightheadedness on standing.

Nortriptyline at a glance
What patients usually want to know first
Nortriptyline is a prescription antidepressant that can also be used for nerve pain or migraine prevention.
In the UK, nortriptyline tablets are supplied as an MHRA-licensed medicine and are prescription only.
That means you cannot buy it over the counter, and a pharmacist will normally dispense it only against a valid prescription.
In the UK nortriptyline is supplied as generic tablets and capsules, with 10 mg and 25 mg being the most familiar strengths.
For many patients, the first few days feel a bit odd rather than dramatic.
Some notice drowsiness, a dry mouth, or dizziness before they notice any improvement in mood or pain.
That is why prescribers often start cautiously and why pharmacy counselling matters so much.
Who it is for: adults prescribed a tricyclic antidepressant for depression, neuropathic pain, migraine prevention, or other specialist uses.
Who it is not for: people with recent heart attack, arrhythmias, MAOI use, severe liver impairment, or other contraindications checked by a prescriber.
How it is supplied: on a doctor’s prescription, dispensed by a pharmacy.
What nortriptyline is and how it fits in the tca group
Simple definition and classification
Nortriptyline is a secondary amine tricyclic antidepressant, usually shortened to a TCA antidepressant.
It sits in the nervous system group, under psychoanaleptics and antidepressants, with ATC code N06AA10.
Many patients hear the name and wonder whether it is just another “strong antidepressant”, but the practical difference is often about tolerability.
Compared with amitriptyline, nortriptyline is considered less sedating and less anticholinergic in many patients.
That is one reason prescribers may choose it when they want a tricyclic effect without pushing the side effects too hard.
As a prescription medicine, it is always supplied under medical supervision, not as an over-the-counter option.
- INN
- International Nonproprietary Name for nortriptyline.
- ATC
- An anatomical therapeutic classification code; for this medicine it is N06AA10.
- Rx-only
- Prescription only, so a doctor must authorise supply.
- TCA
- Tricyclic antidepressant, a long-established antidepressant family.

Approved uses and common off-label uses
Depression first, then pain and migraine
Some people are prescribed nortriptyline for low mood and loss of interest, while others receive it for burning pain or migraine prevention.
That difference matters because the same medicine may be used with different dosing schedules depending on the indication.
Its approved use is for major depressive disorder, and it is also commonly used off-label for neuropathic pain, migraine prophylaxis, and sometimes fibromyalgia.
Patients are often surprised that a medicine classed as an antidepressant is also used for pain.
The reason is that tricyclic antidepressants can modulate nerve signalling as well as mood symptoms.
For pain or migraine, prescribers often favour bedtime dosing and lower starting doses because daytime sedation can be more troublesome.
| Indication | Typical use | Usual starting dose |
|---|---|---|
| Major depressive disorder | Treatment of low mood symptoms | 25 mg, 3–4 times daily |
| Neuropathic pain | Off-label pain control | 10–25 mg at bedtime |
| Migraine prevention | Off-label prophylaxis | 10–25 mg at bedtime |
| Fibromyalgia | Off-label symptom control | 10–25 mg at bedtime |
Dosing basics and how treatment is usually started
Typical adult starting doses and titration
Prescribers usually start cautiously and adjust to response and tolerance.
For depression, the typical adult starting dose is 25 mg, three to four times daily, with a maximum of 75 to 150 mg per day.
For neuropathic pain, migraine, and fibromyalgia, the common starting dose is 10 to 25 mg at bedtime, with titration up to 75 mg per day.
This low-and-slow approach is especially common with tricyclic antidepressants because side effects can appear before the benefit does.
A patient who feels sleepy after the first dose may need a timing change or a slower increase rather than immediate abandonment of treatment.
Doctors also individualise the regimen because sedation, constipation, and orthostatic symptoms can vary widely from person to person.
The best advice is to follow the dispensing label exactly and not to copy a friend’s dose, even if the tablets look the same.
| Indication | Starting dose | Maximum dose | Notes |
|---|---|---|---|
| Depression | 25 mg, 3–4 times daily | 75–150 mg per day | Adjust to response and tolerance |
| Neuropathic pain | 10–25 mg at bedtime | 75 mg per day | Titrate as tolerated |
| Migraine or fibromyalgia | 10–25 mg at bedtime | 75 mg per day | Monitor carefully |
Dose adjustments for older adults and special populations
Who needs lower doses and closer monitoring
Older people often need a gentler start because anticholinergic and central nervous system effects are more likely to cause problems.
Children are not routinely recommended to take this medicine, and if it is used rarely, specialist oversight is needed.
With liver impairment, caution is important because hepatic metabolism is the main route of handling the medicine.
Kidney impairment usually does not require a major dose change, but severe dysfunction still calls for monitoring.
In frail older adults, constipation, confusion, urinary retention, and falls are the side effects that tend to matter most in day-to-day life.
- Children
- Not routinely recommended; if used, start low and keep strict specialist supervision.
- Elderly patients
- Start at 10–25 mg daily, titrate more slowly, and watch for anticholinergic and CNS effects.
- Liver impairment
- Use cautiously and consider dose reduction because hepatic metabolism is primary.
- Kidney impairment
- Usually no major adjustment, but monitor if renal dysfunction is severe.
How long treatment takes and what patients should expect
Onset, maintenance and long-term use
One of the most common frustrations is expecting immediate relief.
Nortriptyline onset of action is gradual, and mood benefit often begins after 2 to 4 weeks rather than overnight.
For depression, treatment is usually continued for at least 6 months after symptoms improve.
For neuropathic pain, many prescribers review response after 2 to 3 weeks and then decide whether to continue.
That means treatment is not just about starting the tablets, but about follow-up, dose adjustment, and checking how the patient is coping.
Pharmacists can be especially useful during the early weeks when side effects and uncertainty are most common.
A patient who is half-way through the first month and still waiting for benefit is not unusual, provided the medicine is being reviewed properly.
Start: low dose and careful timing.
Review: after 2 to 3 weeks for pain, or within the first month for mood symptoms.
Maintenance: continue for the recommended period once benefit is clear.
How to take nortriptyline safely day to day
Missed doses, timing and everyday use
Patients often ask what to do when a dose is forgotten after a busy day or a late night.
If a dose is missed, take it as soon as remembered unless it is close to the next scheduled dose.
Do not double the dose.
That simple rule matters because too much nortriptyline can cause dangerous effects, including cardiac toxicity and central nervous system symptoms.
Bedtime dosing is common for pain regimens, while depression regimens may be divided through the day as prescribed.
Follow the exact directions on the dispensing label rather than old prescriptions.
Using phone reminders, pharmacy labels, and counselling at the counter can make adherence much easier.
- Do take it at the same time each day where possible.
- Do use a reminder if you are likely to forget doses.
- Do not take two doses together after a missed tablet.
- Do not change the timing without checking with a pharmacist or prescriber.
Side effects patients most often notice
Common, mild to moderate effects
Side effects are one of the main reasons patients stop a tricyclic early, so it helps to know what is common and what can be managed.
Dry mouth, constipation, drowsiness, dizziness, and blurred vision are among the effects patients mention most often.
Urinary retention, weight gain, increased sweating, orthostatic hypotension, mild tremor, and sexual dysfunction can also occur.
Some of these affect work and driving more than others, especially drowsiness and dizziness on standing.
Many people cope better when they hydrate well, stand up slowly, and avoid rushing from bed or a chair.
If side effects are troublesome, the prescriber may need to adjust the dose or timing rather than stopping the medicine abruptly.
| Side effect | How it often feels in practice | Self-care | When to seek help |
|---|---|---|---|
| Dry mouth | Sticky mouth, thirst, discomfort when speaking | Sip water, use sugar-free gum | If severe or persistent |
| Constipation | Infrequent, hard stools | Fluids, fibre, routine activity | If worsening or painful |
| Drowsiness | Sleepiness, reduced alertness | Bedtime dosing if prescribed | If affecting driving or work |
| Dizziness on standing | Lightheadedness, unsteady feeling | Rise slowly, hold support | If you faint or fall |
| Blurred vision | Difficulty focusing | Allow time before driving | If sudden or severe |
| Urinary retention | Difficulty passing urine | None specific | Seek prompt advice |
Serious risks, contraindications and who should not take it
Absolute and relative contraindications
Before supply, pharmacists and prescribers ask about heart history, eye conditions, urinary symptoms, and mental health because those details change the risk profile.
Recent myocardial infarction, arrhythmias, hypersensitivity to the medicine or other tricyclics, MAOI use, and severe liver impairment are major red flags.
MAO inhibitors are especially important because they must not overlap, and a 14-day gap after stopping an MAOI is required.
Some conditions do not always stop treatment, but they do require close supervision and a clear reason for use.
That includes epilepsy, glaucoma, prostatic hypertrophy or urinary retention, thyroid disease, and bipolar disorder.
- Absolute contraindications
- Recent myocardial infarction, arrhythmias, hypersensitivity, MAOI use, and severe liver impairment.
- Relative contraindications
- Epilepsy, glaucoma, prostatic hypertrophy or urinary retention, thyroid disease, and bipolar disorder.
Interactions and monitoring
CYP2D6 and medicines that may change exposure
Nortriptyline is a CYP2D6 substrate, so medicines that inhibit or alter CYP2D6 activity can change exposure and side effect risk.
That is why a full medication review matters.
It matters just as much for OTC products, herbal remedies, and alcohol use, because the risk is not limited to prescription-only medicines.
If the patient has cardiac history or the dose is being increased, clinical monitoring and sometimes an ECG may be considered.
| Interaction type | Example | Action |
|---|---|---|
| CYP2D6 change | Medicine that inhibits CYP2D6 activity | Check for increased exposure risk |
| MAOI overlap | MAO inhibitor use or recent use | Do not dispense without prescriber review |
| Cardiac risk | History of arrhythmia or recent infarction | Refer back to prescriber |
| Multiple medicines | Polypharmacy, alcohol, OTC use | Carry out a full medication check |
Storage and alternatives
Storage and alternative medicines
Nortriptyline should be stored at room temperature, between 15 and 30°C, away from moisture and light.
When travelling, keep it in the original closed packaging and out of reach of children.
That sounds basic, but packaging matters because tablets can be damaged by damp bathroom storage or loose pill organisers if used carelessly.
When choosing between nortriptyline and alternatives, prescribers mainly compare sedation and anticholinergic burden.
Amitriptyline is often used for depression and pain, but it is usually more sedative and more anticholinergic.
Imipramine is an older TCA, and doxepin is generally more sedative.
Modern SNRIs such as duloxetine and venlafaxine are not TCAs and generally cause fewer anticholinergic effects.
That is why nortriptyline may be chosen when a prescriber wants an older, established option with a different tolerability profile.
| Alternative | Typical use | Key difference | Practical relevance |
|---|---|---|---|
| Amitriptyline | Depression and pain | Often more sedative | May suit night-time use, but side effects can be heavier |
| Imipramine | Older antidepressant use | Older TCA profile | Less commonly chosen where tolerability is a concern |
| Doxepin | Depression or sleep-related use | More sedative | Alertness and next-day effects need checking |
| Duloxetine or venlafaxine | Depression and pain | Non-TCA, fewer anticholinergic effects | Often considered when dry mouth or constipation are a problem |

Final practical takeaway for patients
Nortriptyline is a long-established prescription antidepressant with useful roles in depression, neuropathic pain, and migraine prevention.
It is not an instant medicine, and it is not a casual over-the-counter purchase.
The main things patients need to remember are the dose schedule, the common side effects, and the reasons why heart history, eye problems, and MAOI use are so important.
If you have been prescribed nortriptyline tablets in the UK, the safest approach is to keep to the label, give the medicine time to work, and ask a pharmacist if anything feels unusual.
That simple step often prevents avoidable problems and helps treatment stay on track.
