Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Nortriptyline (Pamelor) and duloxetine (Cymbalta) are both used to treat depression, but they belong to different classes of medications. Nortriptyline is a tricyclic antidepressant (TCA) that works by adjusting levels of serotonin and norepinephrine in the brain, while duloxetine is a serotonin and norepinephrine reuptake inhibitor (SNRI) that also raises these chemicals. Nortriptyline is typically taken multiple times a day, whereas duloxetine is usually taken once daily. Duloxetine is also approved to treat anxiety, diabetic neuropathy, fibromyalgia, and long-term pain, making it more versatile than nortriptyline, which is sometimes used off-label for chronic pain and nerve pain. Both medications can cause withdrawal symptoms if stopped abruptly, but duloxetine has a higher risk of liver damage, especially if you drink alcohol. Nortriptyline may take longer to show full effects, typically 6 to 8 weeks, compared to duloxetine, which can start showing improvements in mood within 1 to 2 weeks. Both medications are available in generic forms, making them more affordable options.
