Pharmacologic: five ht1 agonists
Acute treatment of migraine headache.
Acts as an agonist at specific 5-HT receptor sites in intracranial blood vessels and sensory trigeminal nerves.
Cranial vessel vasoconstriction with associated decrease in release of neuropeptides and resultant decrease in migraine headache.
Absorption: 20–30% following oral administration.
Metabolism and Excretion: Mostly metabolized by the liver (P450 1A2 enzyme system); some metabolites eliminated in urine, <10% excreted unchanged.
Half-life: 26 hr.
Time/action profile (blood levels)
Contraindicated in: Hypersensitivity;History, symptoms or findings consistent with;Cerebrovascular syndromes including;Uncontrolled hypertension;Hemiplegic or basilar migraine;Peripheral vascular disease, including ischemic bowel disease;Should not be used within 24 hr of any other 5-HT agonist or ergot-type compounds (e.g. dihydroergotamine, ergotamine); Pediatric: Children <18 yr.
Use Cautiously in: Concurrent use of SSRIs or SNRIs (↑ risk of serotonin syndrome); Geriatric: May be more susceptible to adverse cardiovascular effects; Obstetric / Lactation: Safety not established.
Exercise Extreme Caution in: Cardiovascular risk factors (hypertension, hypercholesterolemia, cigarette smoking, obesity, diabetes, strong family history, menopausal women or men >40 yr); use only if cardiovascular status has been evaluated and determined to be safe and first dose is administered under supervision.

- coronary artery vasospasm (life-threatening)
- mi (life-threatening)
- ventricular fibrillation (life-threatening)
- ventricular tachycardia (life-threatening)
- chest pain
- myocardial ischemia
- dry mouth
- skeletal pain
Drug-Drug interactionHormonal contraceptives or propranolol may ↑ levels.↑ risk of serious vasospastic reactions with dihydroergotamine or ergotamine (concurrent use contraindicated).↑ risk of serotonin syndrome when used with fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram, venlafaxine, or duloxetine.
Oral (Adults) 2.5 mg; if there has been initial relief, a second tablet may be taken after at least 2 hr (daily dose should not exceed 3 tablets and should not be used to treat more than 4 attacks/30 day period).
Tablets: 2.5 mg
- Assess pain location, intensity, duration, and associated symptoms (photophobia, phonophobia, nausea, vomiting) during migraine attack.
Potential Nursing DiagnosesAcute pain (Indications)
- Oral: Tablets may be administered at any time after the headache starts.
- 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.
- Relief of migraine attack.
