Drug Prescriptions

The goal of this prospective intervention study is to investigate the effectiveness of redispensing unused oral anticancer drugs. The main questions it aims to answer are: * What are the cost-savings of redispensing unused oral anticancer drugs? * What is the environmental impact of redispensing unused oral anticancer drugs? Researchers will compare redispensing unused oral anticancer drugs to the standard practice of disposal. Participants will receive their oral anticancer drugs in a sealed bag with a temperature indicator if needed. They will be asked to return any unused oral anticancer drugs to the pharmacy during their next visit to the hospital.
