Name one side effect of caspofungin.

Caspofungin, an echinocandin antifungal agent, is known to potentially cause histamine-mediated reactions. These reactions arise due to the release of histamine from mast cells, which can lead to symptoms such as flushing, rash, and, in some cases, hypotension. This side effect is particularly important to monitor during administration, as it demonstrates the drug's impact on the immune system and may necessitate premedication with antihistamines to prevent discomfort for the patient.

In contrast, the other side effects listed, such as constipation, headache, and nausea, are not typically associated with caspofungin. While patients might experience these symptoms as commonplace side effects of other medications or treatments, they are less specific to caspofungin than the histamine-mediated reactions. Understanding the unique side effect profile of caspofungin enables healthcare providers to prepare for and manage potential adverse effects effectively.
