Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Amitriptyline (generic, formerly branded as Elavil) and desipramine (Norpramin) are both tricyclic antidepressants (TCAs) used to treat depression. Amitriptyline is often used off-label for nerve pain and migraine prevention, while desipramine is not. Amitriptyline can cause sleepiness and weight gain, and it has many interactions with other medications. Desipramine also causes sleepiness and weight gain but is more likely to cause confusion and anxiety. Amitriptyline is typically taken in divided doses or once at bedtime, whereas desipramine is usually taken once daily. Both medications can cause serious side effects like suicidal thoughts and heart problems, but desipramine has an additional risk of serotonin syndrome. Both are available in generic forms and are not controlled substances.

Summary of Elavil vs. Desipramine
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.
Summary for Tricyclic antidepressant (TCA)
Prescription only
Desipramine (Norpramin) is an tricyclic antidepressant (TCA). It's FDA-approved to treat depression in adults, but it's not a first-choice medication for this condition. Desipramine (Norpramin) is taken by mouth, typically once per day. Side effects of this medication include sleepiness, confusion, and weight gain. It's best to avoid drinking alcohol while taking desipramine (Norpramin) because doing so can worsen side effects.
