What is Ubrelvy?

Ubrelvy tablets are used to treat migraine headaches in adults, that are with or without aura. Ubrelvy works by blocking a protein called CGRP in the nerve endings that are involved in pain and migraines, this helps reduce pain and migraine symptoms. Ubrelvy is from the CGRP inhibitor class of medicines and is a prescription medicine.

  • Ubrelvy is used when you have a migraine headache; it is not used to prevent a migraine headache.

The Ubrelvy dose is 50mg to 100 mg at the start of the migraine, then after 2 hours, a second dose may be taken if needed.

Ubrelvy (ubrogepant) received FDA approval on December 23, 2019, for the acute treatment of migraine with or without aura in adults. They are available as Ubrelvy 100mg tablets and Ubrelvy 50mg tablets.

There is no generic Ubrelvy available.

Ubrelvy's active ingredient is ubrogepant; some people call this the Ubrelvy generic name.

Ubrelvy (ubrogepant) works by blocking the activity of calcitonin gene-related peptide (CGRP), a protein that plays a key role in migraine attacks.

Ubrelvy mechanism of action involves binding to CGRP receptors and preventing CGRP from triggering inflammation, dilation of blood vessels, and pain in the brain. By inhibiting CGRP, Ubrelvy helps reduce migraine symptoms such as headache, nausea, and sensitivity to light and sound. It is unlike some traditional migraine treatments, which constrict blood vessels. Ubrelvy specifically targets this pathway without causing vascular side effects.

What is a migraine cocktail and what’s in it?
A migraine cocktail is not an actual drink, but a combination of medications administered to help people with severe or treatment-resistant migraines find relief. It is most often given in an emergency room (ER) or urgent care setting. When standard home medications fail to control symptoms, healthcare providers use these medication mixtures to target multiple migraine pathways at once. Continue reading
Ubrelvy vs Imitrex (sumatriptan): How do they compare?
Ubrelvy and Imitrex are both oral tablets used to treat migraine, but there are differences in the way they work. Ubrelvy prevents a protein called CGRP thought to play a role in migraine attacks from binding to its receptor and Imitrex is thought to bind to serotonin 5‑HT1B/1D receptors, and inhibit pro-inflammatory substances Although no head-to-head comparison trials compare Ubrelvy to Imitrex, indirect evidence suggests that overall, Ubrelvy is no more effective, and may be inferior to Imitrex at relieving migraine in adults who are able to tolerate triptans. For those adults with moderate-to-severe migraine attacks that cannot tolerate triptans or who have found them ineffective, Ubrelvy is beneficial for treating migraines compared to no treatment. Ubrelvy is associated with fewer side effects than Imitrex, but is more expensive, costing almost twice as much. Continue reading
Is Ubrelvy better than triptans?
Head-to-head clinical studies of Ubrelvy and triptans are not available, but both are proven prescription medicines approved to treat acute migraine headaches with or without aura in adults. The best option for you depends on your past treatments and side effects, medical conditions (especially heart and blood vessel disease), migraine features, and cost and insurance coverage. Continue reading
What is the mechanism of action for Ubrelvy?
The mechanism of action for Ubrelvy involves blocking a nerve protein called calcitonin gene‑related peptide (CGRP) that contributes to migraine headache pain. Ubrelvy attaches to CGRP receptors on sensory nerve endings and prevents CGRP from binding. This helps reduce blood vessel dilation, inflammation, and pain signaling that occur during a migraine attack. Continue reading
Is Ubrelvy a narcotic used for migraine?
No, Ubrelvy (generic name: ubrogepant) is not a narcotic, not an opioid, and not a controlled substance in the United States. It is a prescription migraine medicine in a newer class called calcitonin gene‑related peptide (CGRP) receptor antagonists (“gepants”), used for the acute treatment of migraine attacks with or without aura in adults. Continue reading
Does Ubrelvy cause rebound headaches?
No, Ubrelvy (ubrogepant) has not been linked to rebound headaches, also called medication overuse headaches (MOH). Older migraine drugs like triptans, NSAIDs, and opioids can cause rebound headaches when used too often. Ubrelvy belongs to a newer class called gepants, and studies so far have not found this problem. Even so, the FDA has not established that it is safe to treat more than 8 migraines in 30 days with Ubrelvy. Continue reading
Does Ubrelvy affect the liver?
No reports of clinically apparent liver injury were made during clinical development of Ubrelvy (ubrogepant) and none have been made since the drug’s launch in the US in 2019. Continue reading
