Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Amitriptyline (formerly branded as Elavil) and lamotrigine (Lamictal) are both prescription medications, but they are used for different conditions 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. It works by increasing levels of serotonin and norepinephrine in the brain. On the other hand, lamotrigine is an antiepileptic medication used to treat seizures and bipolar disorder. Its exact mechanism for these conditions isn't fully understood, but it helps to stabilize electrical activity in the brain. lamotrigine is also used off-label for migraine prevention. Amitriptyline can cause side effects like sleepiness, weight gain, and dizziness, and it has many interactions with other medications. Lamotrigine can also cause dizziness and has a risk of serious skin reactions, such as rash, especially if the dose is increased too quickly. Both medications are available in generic forms, making them more affordable. However, lamotrigine comes in various formulations, including immediate-release and extended-release tablets, while amitriptyline is typically taken in tablet form. Additionally, lamotrigine requires careful dose adjustments to minimize the risk of severe side effects, whereas amitriptyline's dose is adjusted based on response and side effects.

Summary of Elavil vs. Lamictal
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.
