A new commentary from Duke Health, published in the Journal of Clinical Oncology, warns that common over‑the‑counter and prescription medicines may change immunotherapy results. Lead author Nicholas DeVito, an assistant professor in medical oncology at Duke University School of Medicine, said interactions with the immune system are often not considered.
The authors reviewed more than 50 studies and found evidence that several widely used drugs can affect immunotherapy. Some drugs appear to reduce how well immunotherapy works, while others may improve response; the commentary also notes that some medicines can cause or increase side effects during treatment.
The researchers recommend better and more consistent recording of all medications in clinical trials, prospective studies to confirm these findings, and practical changes in care such as patient education and electronic health record prompts for clinicians.
