Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Amitriptyline (formerly branded as Elavil) and Silenor (doxepin) are both tricyclic antidepressants, but they are used for different purposes. Amitriptyline is primarily FDA approved to treat depression, though it is also used off-label for nerve pain and migraine prevention. In contrast, Silenor is specifically approved to treat insomnia, helping you stay asleep through the night. Amitriptyline can cause a range of side effects, including sleepiness, weight gain, and dizziness, and it has many interactions with other medications. Silenor, on the other hand, is noted for not being addictive and is generally taken once daily before bedtime. However, it can cause sleepiness and unusual behaviors while not fully awake. While both medications can worsen depression or cause suicidal thoughts, this risk is more pronounced in younger individuals. Additionally, Silenor should be taken on an empty stomach, unlike amitriptyline, which can be taken with or without food.

Summary of Elavil vs. Silenor
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
Prescription only
Doxepin (Silenor) is a tricyclic antidepressant that's used to help adults who have insomnia (trouble sleeping) stay asleep. Doxepin (Silenor) is a tablet that you take by mouth 30 minutes before bedtime. As expected, the most common side effects are sleepiness and tiredness, so only take the medication when you're ready to fall asleep for the night. Unlike some other sleep medications, doxepin (Silenor) isn't considered a controlled substance. Doxepin (Silenor) is available as brand-name and generic versions.
