Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Amitriptyline (formerly branded as Elavil) and nortriptyline (Pamelor) are both tricyclic antidepressants (TCAs) used to treat depression, but they have some differences. Amitriptyline is often used off-label for nerve pain and migraine prevention, while nortriptyline is also used off-label for chronic pain and diabetes-related nerve pain. Amitriptyline can cause more side effects like sleepiness and weight gain, whereas nortriptyline is generally better tolerated with fewer side effects. The typical dose for amitriptyline is 50 mg to 100 mg per day, while nortriptyline is usually taken at 25 mg three or four times daily. Both medications can cause serious side effects like suicidal thoughts and heart problems, but nortriptyline has a specific warning for serotonin syndrome. Additionally, nortriptyline is available in both capsule and liquid forms, making it easier for those who have trouble swallowing pills.

Summary of Elavil vs. Pamelor
Summary for Tricyclic antidepressant
Prescription only
Amitriptyline is FDA approved to treat depression. But it isn't as commonly used today as other antidepressants because it can cause a lot of side effects, such as sleepiness and weight gain. In addition, amitriptyline has many interactions with other medications, including other antidepressants, sedatives, and antihistamines. But despite the side effects and interactions, amitriptyline is often used off label for nerve pain due to diabetes and migraine prevention. While its brand name Elavil is no longer available, amitriptyline is available as a generic medication.
