Final answer:
Imitrex (sumatriptan) is contraindicated for those with certain heart conditions, stroke, peripheral vascular disease, severe liver impairment, and hypersensitivity to the drug. It is also contraindicated for those taking certain medications like monoamine oxidase inhibitors, ergotamines, or other triptans.
Step-by-step explanation:
Imitrex, which is the brand name for sumatriptan, is contraindicated in certain situations. Contraindications (c/I) include a history of heart diseases, such as coronary artery disease, angina, heart attacks, or uncontrolled hypertension. Additionally, it should not be used by patients who have had a stroke or transient ischemic attacks, those with peripheral vascular disease, or by individuals with severe liver impairment.
Sumatriptan should also be avoided by individuals who have hypersensitivity to the drug and those using concomitant medications such as monoamine oxidase inhibitors, ergotamines, or other triptans due to the risk of serotonin syndrome. Other risk factors, like pregnancy and breastfeeding, require careful consideration and consultation with a healthcare provider.
