Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Amitriptyline (formerly branded as Elavil) and trazodone (formerly branded as Desyrel) are both used to treat depression, but they belong to different classes of medications. Amitriptyline is a tricyclic antidepressant (TCA) that works by increasing serotonin and norepinephrine levels in the brain, while trazodone is an atypical antidepressant known as a serotonin antagonist and reuptake inhibitor (SARI). Amitriptyline is often used off-label for nerve pain and migraine prevention, whereas trazodone is sometimes prescribed off-label for insomnia. Amitriptyline can cause side effects like weight gain and sleepiness, and it has many interactions with other medications. Trazodone, on the other hand, is not a first-choice medication for depression and can cause side effects such as sleepiness, dry mouth, and dizziness. Both medications can cause withdrawal symptoms if stopped abruptly and are not controlled substances.

Summary of Elavil vs. Desyrel
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.
