A prescriber orders sumatriptan (Imitrex) for a patient for a migraine headache. Prior to administration of this drug, it would be important for the nurse to gather which vital assessment information?
a. Does the patient have a family history of migraines?
b. Has the patient taken ergotamine in the past 24 hours?
c. Has the patient taken acetaminophen in the past 3 hours?
d. Is the patient allergic to sulfa compounds?
B
Sumatriptan, other triptans, and ergot alkaloids all cause vasoconstriction and should not be combined, or excessive and prolonged vasospasm could result. Sumatriptan should not be used within 24 hours of an ergot derivative and another triptan.
A family history is important, but it is not vital assessment data as it relates to this scenario.
Acetaminophen has no drug-to-drug interaction with sumatriptan
Sulfa is not a component of sumatriptan and is therefore not relevant.
