Nortriptyline: What It Treats and How to Use It Safely

Are you looking up nortriptyline because a doctor mentioned it? Nortriptyline is a tricyclic antidepressant that people use for depression, certain types of nerve pain, and migraine prevention. It works differently from SSRIs, and some patients respond better to it. This page gives straightforward, usable info so you know what to expect and what questions to ask your prescriber.

How Nortriptyline Works and Typical Uses

Nortriptyline boosts levels of norepinephrine and serotonin in the brain, which helps mood and pain signals. Doctors commonly prescribe it for major depressive disorder, diabetic neuropathy or other chronic nerve pain, and as a preventive for migraines. It’s also used off-label for insomnia and some types of chronic pain. Expect mood improvements to appear over 2–4 weeks; pain relief can take a few weeks too.

Typical starting doses are low—often 10–25 mg at bedtime—to reduce drowsiness and dizziness. Maintenance doses usually range from 25–150 mg daily, split or at night depending on how you tolerate it. Older adults and people with certain health issues usually start lower and go slower.

Side Effects, Interactions, and Practical Safety Tips

Common side effects include dry mouth, drowsiness, constipation, blurred vision, and sometimes weight gain. Because nortriptyline has anticholinergic effects, it can cause urinary retention and confusion in older adults. It can also lower blood pressure when you stand up—stand slowly to avoid fainting.

Nortriptyline interacts with several drugs. Don’t combine it with MAO inhibitors, and use caution with SSRIs, antipsychotics, blood pressure meds, and other drugs that prolong the QT interval. Alcohol and sedatives increase drowsiness and risk. If you take many medicines, ask your pharmacist or doctor to check for interactions.

Stoping suddenly can cause withdrawal symptoms like irritability, sleep trouble, and flu-like feelings. If your prescriber wants you off nortriptyline, they’ll usually taper the dose slowly.

Practical tips: take it at night if it makes you sleepy; take with food if it upsets your stomach; avoid driving until you know how it affects you. If you have heart disease, glaucoma, prostate enlargement, or a history of seizures, mention this—your doctor may order an ECG or choose a different medicine.

Seek urgent care for chest pain, severe fainting, very rapid or irregular heartbeat, extreme confusion, or signs of an allergic reaction. Also contact your prescriber right away if you experience new or worsening depression, suicidal thoughts, or unusual behavior—especially in young adults under 25.
