Nursing implications

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

Potential Nursing Diagnoses

Acute pain (Indications)

Implementation

  • Oral: Tablets may be administered at any time after the headache starts.

Patient/Family Teaching

  • Inform patient that frovatriptan should be used only during a migraine attack. It is meant to be used to relieve migraine attack but not to prevent or reduce the number of attacks.
    • Instruct patient to administer frovatriptan as soon as symptoms 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 3 tablets in any 24-hr period.
    • If dose does not relieve headache, additional frovatriptan doses are not likely to be effective; notify health care professional.
    • Advise patient that lying down in a darkened room following frovatriptan administration may further help relieve headache.
    • Caution patient not to use frovatriptan if she is pregnant, suspects she is pregnant, plans to become pregnant, or is breast feeding. Adequate contraception should be used during therapy.
    • May cause dizziness or drowsiness. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
    • Advise patient that overuse (use more than 10 days/month) may lead to exacerbation of headache (migraine-like daily headaches, or as a marked increase in frequency of migraine attacks). May require gradual withdrawal of frovatriptan and treatment of symptoms (transient worsening of headache).
    • Advise patient to notify health care professional prior to next dose of frovatriptan if pain or tightness in the chest occurs during use. If pain is severe or does not subside, notify health care professional immediately. If wheezing; heart throbbing; swelling of eyelids, face, or lips; skin rash; skin lumps; or hives occur, notify health care professional immediately and do not take more frovatriptan without approval of health care professional. If feelings of tingling, heat, flushing, heaviness, pressure, drowsiness, dizziness, tiredness, or sickness develop, discuss with health care professional at next visit.
    • Advise patient to avoid alcohol, which aggravates headaches, during frovatriptan use.

Evaluation/Desired Outcomes

  • Relief of migraine attack.
