Vascular toxicity occurs generally within 72 hours of the first cycle of chemotherapy.

Rechallenge should be in bolus rather than infusion and should be with informed consent, pre-treatment with aspirin, continuous monitoring, nitrates and calcium channel blockers, ideally in a coronary care unit and to be considered only if there is no other reasonable alternative cancer therapy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which chemotherapeutic agent is well known to cause coronary vasospasm? 5-fluorouracil is well known to cause coronary vasospasm.&nbsp;5-fluorouracil and its orally active prodrug capecitabine are fluoropyrimidines, belonging to the class of antimetabolites used for treatment of malignancies of breast, head and neck tumours and gastrointestinal tumours.
