Capecitabine induced vasospastic angina.

Cardiotoxicity is a recognised side effect of intravenous 5-fluorouracils. In the two case reports described we demonstrate similar cardiotoxic side effects seen with the use of capecitabine. With the increasing use of oral adjuvant chemotherapeutic agents, capecitabine should be used with caution in those patients with existing coronary artery disease.
