What Is Nortriptyline? Uses, Dosage, and What You Need to Know in 2026

Nortriptyline is a prescription medication that has been in clinical use since 1963. Despite being one of the older antidepressants available, it remains widely prescribed today — not just for depression, but for a range of conditions including nerve pain, migraine prevention, and smoking cessation.

Here's what you need to know about nortriptyline in 2026.

What Is Nortriptyline?

Nortriptyline is a tricyclic antidepressant (TCA) — one of the earliest classes of antidepressants developed. It is the active metabolite of amitriptyline, meaning when you take amitriptyline, your body converts it to nortriptyline. Nortriptyline itself is considered better tolerated than amitriptyline because it causes less sedation and fewer anticholinergic side effects.

Brand names: Nortriptyline is sold under the brand name Pamelor in the United States. The brand Aventyl is no longer actively marketed in the U.S. Generic nortriptyline is widely available from multiple manufacturers.

What Is Nortriptyline Used For?

FDA-approved indication: Depression in adults.

Common off-label uses (prescribed by doctors but not FDA-approved for these conditions):

Neuropathic pain (nerve pain from diabetes, shingles, injury)

Postherpetic neuralgia (pain after shingles)

Migraine prevention

Myofascial pain and chronic musculoskeletal pain

Smoking cessation (as an aid to quit smoking)

ADHD in adults

Burning mouth syndrome and orofacial pain

What Forms and Strengths Does Nortriptyline Come In?

Nortriptyline is available as:

Capsules: 10 mg, 25 mg, 50 mg, and 75 mg

Oral solution: 10 mg per 5 mL (473 mL bottle); useful for patients who have difficulty swallowing capsules or need fine dose adjustments

Typical Nortriptyline Dosage

Dosing depends on what condition is being treated:

For depression: Usually starts at 25 mg/day and increases over several weeks to 75-150 mg/day. Maximum recommended dose is 150 mg/day (some patients tolerate up to 200 mg under close monitoring).

For neuropathic pain: Lower doses are used — typically 10-75 mg/day, often taken at bedtime. Pain relief usually occurs at doses lower than those needed for depression.

For elderly patients: Lower starting doses are used due to increased sensitivity to anticholinergic and cardiovascular side effects.

The total daily dose can be taken once at bedtime or divided into multiple daily doses. Many patients find once-daily bedtime dosing most convenient and tolerable.

Who Should NOT Take Nortriptyline?

Nortriptyline is contraindicated or requires extreme caution in:

Patients who recently had a heart attack (myocardial infarction)

Patients who have taken an MAOI within the last 14 days (at least 5 weeks after fluoxetine)

Patients with acute porphyria

Children under 18 years old (not FDA-approved for pediatric use)

Patients with hypersensitivity to nortriptyline or other TCAs

How Long Does It Take for Nortriptyline to Work?

For depression: Full antidepressant effects may not be evident for 2-6 weeks after reaching a therapeutic dose. Many patients notice mood improvements beginning at 2-3 weeks, with full benefit at 4-8 weeks.

For pain: Pain relief from low-dose nortriptyline may occur somewhat sooner — within 1-4 weeks for neuropathic pain — and at doses lower than those needed for depression.

Is Nortriptyline a Controlled Substance?

No. Nortriptyline is not a DEA-scheduled controlled substance. It can be prescribed by any licensed healthcare provider and filled at any pharmacy without special restrictions. Prescriptions can be refilled according to standard prescription rules in your state.
