  •  Moderate CYP3A4 inhibitors  as well as  weak CYP3A4 inhibitors, including  ciprofloxacin,  cyclosporine,  fluconazole,  fluvoxamine, or  verapamil  may ↑ levels and risk of toxicity; ↓ ubrogepant dose.
  •  Strong CYP3A4 inducers, including  phenobarbital,  phenytoin, or  rifampin  may significantly ↓ levels and effectiveness; avoid concurrent use.
  •  Moderate CYP3A4 inducers  or  weak CYP3A4 inducers  may ↓ levels and effectiveness; ↑ ubrogepant dose.
  •  P-glycoprotein (P-gp) inhibitors  as well as  breast cancer resistant protein (BCRP) inhibitors, including  carvedilol,  eltrombopag, or  quinidine , may ↑ levels and risk of toxicity; ↓ ubrogepant dose.

Drug-Natural Products:

 St. John's wort  may ↓ levels and effectiveness; avoid concurrent use.

Drug-Food:

Grapefruit juice may ↑ levels and risk of toxicity; ↓ ubrogepant dose.

Availability

Assessment

  • Assess pain location, character, intensity, and duration and associated symptoms (photophobia, phonophobia, nausea, vomiting) during migraine attack.

Implementation

  • PO Administer without regard to food. If needed, a second dose may be taken at least 2 hr after initial dose.

Patient/Family Teaching

  • Instruct patient to take ubrogepant as soon as symptoms of a migraine attack appear, but it may be administered any time during an attack. If migraine symptoms return, a second dose may be used. Allow at least 2 hr between doses, and do not use more than 100 mg in any 24-hr period. Advise patient to read  Patient Information  before starting therapy and with each Rx refill in case of changes.
  • Inform patient that ubrogepant should only be used during a migraine attack. It is meant to be used for relief of migraine attacks but not to prevent or reduce the number of attacks.
  • Advise patient to avoid grapefruit and grapefruit juice during therapy. Instruct patient not take a second tablet within 24 hr if grapefruit or grapefruit juice was consumed.
  • May cause dizziness or drowsiness. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
  • Advise patient to avoid alcohol, which aggravates headaches, during ubrogepant use.
  • Advise patient that lying down in a darkened room following ubrogepant administration may further help relieve headache.
  • Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications, especially St. John's wort.
  • Advise females of reproductive potential to notify health care professional if pregnancy is planned or suspected or if breast feeding.
