Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Amitriptyline (formerly branded as Elavil) and Cafergot (ergotamine/caffeine) are both prescription medications, but they are used for different purposes and belong to different drug classes. Amitriptyline is a tricyclic antidepressant (TCA) primarily used to treat depression, though it is also used off-label for nerve pain and migraine prevention. In contrast, Cafergot is a combination of ergotamine and caffeine, used to treat migraines and cluster headaches. Amitriptyline works by increasing levels of serotonin and norepinephrine in the brain to improve mood, while Cafergot tightens blood vessels and calms certain parts of the brain to relieve headache pain. The brand names for both medications are discontinued, but they are still available in generic forms. Amitriptyline can cause side effects like sleepiness and weight gain, and it has many drug interactions. Cafergot, on the other hand, can cause nausea and numbness and should not be used frequently due to the risk of serious side effects like poor blood flow to the brain and limbs. Additionally, Cafergot is not safe for use during pregnancy, while amitriptyline does not have this specific restriction.

Summary of Elavil vs. Cafergot
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 Ergot derivative / PDE inhibitor, nonselective
Prescription only
Cafergot (ergotamine / caffeine) is used to treat cluster headaches and migraines in adults. It's available as a tablet that's taken by mouth, as well as a suppository that's inserted into the rectum. Typically, you take a dose as soon as you feel a headache coming on. But there's a limit to how many doses you can take each week because taking this medication too often can lead to serious side effects, such as vomiting and numbness. Brand name Cafergot is discontinued.
