Which of the following is a potential side effect of Doxorubicin?

Doxorubicin, an anthracycline chemotherapy drug, is known for several significant side effects, one of which is cardiomyopathy. This condition refers to damage to the heart muscle, which can lead to heart failure and other serious cardiovascular issues. Doxorubicin is particularly notorious for its cumulative cardiotoxic effects, meaning that the risk of heart damage increases with higher cumulative doses of the drug over time. This side effect is a primary concern in veterinary oncology, necessitating careful monitoring of cardiac function in patients receiving this medication.

While the other side effects listed, such as nausea, hepatotoxicity, and thrombocytopenia, are also possible with Doxorubicin, the specific and well-documented risk of cardiomyopathy sets it apart as a critical side effect that practitioners must be vigilant about when treating with this agent.
