How does this medication work? What will it do for me?

Ubrogepant belongs to the class of medications called calcitonin gene-related peptide (CGRP) receptor antagonists. It is used to treat migraines that occur with or without aura. Ubrogepant is not intended to prevent migraines.

Ubrogepant works by blocking the activity of a protein called calcitonin gene-related peptide. For people suffering a migraine attack, this protein is released by the nerves and causes increased pain. This medication prevents the CGRP from binding to pain receptors in the brain.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

How should I use this medication?

The recommended dose of ubrogepant is 50 mg or 100 mg taken by mouth. If the first dose does not relieve symptoms, a second dose may be taken 2 hours later. A second dose may also be used if the migraine is relieved but then returns. The maximum dose is 200 mg during any 24-hour period. The safety of taking more than 16 doses in a 30-day period is not known. For this reason, no more than 16 doses should be taken in a month. If you need to take this medication more frequently, contact your doctor.

Ubrogepant may be taken with or without food. Grapefruit or grapefruit juice should be avoided as ubrogepant may build up in the body and cause an increase in side effects.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
