For patients receiving chemotherapy who develop vomiting, which medication should be given?

Patients undergoing chemotherapy often experience nausea and vomiting as a side effect of their treatment. To manage these symptoms effectively, specific antiemetic medications are utilized. Metoclopramide is a medication that acts as an antiemetic and prokinetic agent, making it particularly effective for individuals experiencing chemotherapy-induced nausea and vomiting.

It works by blocking dopamine receptors in the brain that trigger nausea and also enhances gastric motility, which can help with the overall management of symptoms. By using metoclopramide, healthcare providers can alleviate the distress associated with vomiting, allowing patients to better tolerate their chemotherapy regimen and maintain their nutritional status.

In contrast, the other medications listed do not have a primary role in treating chemotherapy-induced vomiting. Levothyroxine is a thyroid hormone replacement, primarily used for hypothyroidism. Desmopressin is used for conditions like diabetes insipidus and to control bleeding in certain situations, while prednisone is a corticosteroid that may help with inflammatory conditions or as part of a chemotherapeutic regimen but is not specifically indicated for nausea and vomiting. Thus, metoclopramide is the most appropriate choice for patients suffering from these side effects of chemotherapy.
