The primary purpose of premedication in chemotherapy treatments is to prevent or reduce the occurrence of side effects. Chemotherapy can often cause a variety of adverse effects such as nausea, vomiting, allergic reactions, and other specific toxicities related to the particular drugs used. By administering premedications, which may include antiemetics, corticosteroids, or antihistamines, healthcare providers aim to mitigate these side effects, thereby improving patient comfort and adherence to treatment regimens.

While some may think premedications might enhance the effectiveness of the chemotherapy drugs, the main goal is not to increase the therapeutic action of the chemotherapy itself. Increasing the dosage of chemotherapy is not a strategy connected to premedication and could potentially exacerbate toxicities rather than alleviate them. Finally, addressing drug interactions is certainly an important part of medication management, but the specific intent of premedication relates more directly to managing side effects rather than preventing interactions.
