Interactions

Drug-Drug interaction

Because of ↑ risk of cerebral vasospasm, avoid concurrent use of other 5-HT agonists (naratriptan, sumatriptan, rizatriptan ) and/or ergot-type preparations (dihydroergotamine ).Concurrent use of MAO inhibitors ↑ blood levels and risk of toxicity (avoid use within 2 wk of MAO inhibitors).Blood levels may be ↑ by hormonal contraceptives.Cimetidine ↑ half-life of zolmitriptan and its active metabolite.↑ risk of serotonin syndrome when used with SSRI or SNRI antidepressants.↑ risk of serotinergic side effects including serotonin syndrome with St. John’s wort and SAMe.

Route/Dosage

Oral (Adults) 1.25–2.5 mg initially; if headache returns, dose may be repeated after 2 hr (not to exceed 10 mg/24 hr); Concurrent cimetidine therapy—Single dose not to exceed 2.5 mg (not to exceed 5 mg/24 hr).

Intranasal (Adults) single 2.5-mg dose (maximum single dose = 5 mg); may be repeated after 2 hr (not to exceed 10 mg/24 hr); Concurrent cimetidine therapy—Single dose not to exceed 2.5 mg (not to exceed 5 mg/24 hr).

Nursing implications

Nursing assessment

  • Assess pain location, intensity, duration, and associated symptoms (photophobia, phonophobia, nausea, vomiting) during migraine attack.
  • Monitor for serotonin syndrome in patients taking SSRIs or SNRIs concurrently with zolmitriptan.

Potential Nursing Diagnoses

Acute pain (Indications)

Implementation

  • Do not confuse zolmitriptan with sumatriptan.
  • Oral: Initial dose is 2.5 mg. Lower doses can be achieved by breaking 2.5-mg tablet.
    • Orally disintegrating tablets should be left in the package until use. Remove from the blister pouch. Do not push tablet through the blister; peel open the blister pack with dry hands and place tablet on tongue. Do not break orally disintegrating tablet. Tablet will dissolve rapidly and be swallowed with saliva. No liquid is needed to take the orally disintegrating tablet.
  • Intranasal: Remove cap from nasal spray. Hold upright and block one nostril. Tilt head slightly back, insert device into opposite nostril, and depress plunger. May repeat in 2 hr.

Patient/Family Teaching

  • Inform patient that zolmitriptan 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 zolmitriptan as soon as symptoms appear, but it may be administered any time during an attack. If migraine symptoms return, a 2nd dose may be used. Allow at least 2 hr between doses, and do not use more than 10 mg in any 24-hr period.
    • If dose does not relieve headache, additional zolmitriptan doses are not likely to be effective; notify health care professional.
    • Advise patient that lying down in a darkened room following zolmitriptan administration may further help relieve headache.
    • May cause dizziness or drowsiness. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
    • Advise patient to notify health care professional prior to next dose of zolmitriptan 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 zolmitriptan 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 zolmitriptan use.
    • 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 zolmitriptan and treatment of symptoms (transient worsening of 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. Patients concurrently taking SSRI or SNRI antidepressants should notify health care professional promptly if signs of serotonin syndrome (mental status changes: agitation, hallucinations, coma; autonomic instability: tachycardia, labile BP, hyperthermia; neuromuscular aberrations: hyper-reflexia, incoordination; and/or gastrointestinal symptoms: nausea, vomiting, diarrhea) occur.
    • Caution patient not to use zolmitriptan if pregnancy is planned or suspected or if breast feeding. Adequate contraception should be used during therapy.

Evaluation/Desired Outcomes

  • Relief of migraine attack.
