Final answer:
Sumatriptan is contraindicated for clients with a history of cardiovascular diseases, previous strokes or TIAs, peripheral vascular disease, ischemic bowel disease, severe liver impairment, or recent use of MAO inhibitors.
Step-by-step explanation:
When a healthcare provider is preparing a prescription for sumatriptan for a client diagnosed with migraine headaches, it is important to review the client's medical history for any contraindications. Information that would contraindicate the use of sumatriptan includes a history of cardiovascular diseases such as coronary artery disease (CAD), previous myocardial infarction (heart attack), or uncontrolled hypertension (high blood pressure). Additionally, sumatriptan should not be prescribed to individuals who have had a stroke or transient ischemic attacks (TIAs), as well as those with peripheral vascular disease, ischemic bowel disease, or severe liver impairment. People who have taken monoamine oxidase (MAO) inhibitors within the last two weeks should also avoid sumatriptan due to the risk of serotonergic syndrome. Careful consideration of these contraindications is vital to ensure the safety of the patient when prescribing sumatriptan for migraine treatment.
