Three common medicines have been declared carcinogenic. What does this mean for patients?

Author: The Hindu August 15, 2026 Duration: 25:53
Last week, startling headlines hit the news. Three commonly prescribed medicines, hydrochlorothiazide, used to treat high blood pressure, voriconazole, an antifungal medicine and tacrolimus, an immunosuppressant were classified as carcinogenic, or cancer causing, to humans. The classification was made by the International Agency for Research on Cancer or IARC, which is the World Health Organization’s cancer research agency.According to the IARC, there is sufficient evidence that hydrochlorothiazide causes squamous cell carcinoma of the skin and cancer of the lip, as the drug makes the skin more sensitive to ultraviolet radiation. Voriconazole, also has been linked to the same cancers. In the case of Tacrolimus since it suppresses the immune system to prevent rejection of transplanted organs, the reduced immune surveillance may allow abnormal cells to proliferate and it is linked with non-Hodgkin lymphoma with limited evidence for other cancers as well.These drugs are prescribed to millions of people worldwide.

Each week, the journalists at In Focus by The Hindu select one pressing story from the news cycle and slow it down. Rather than a rapid headline, you’ll hear a thoughtful conversation that unpacks the layers behind an event-the historical precedents, the economic forces, the political nuances, and the human impact. This podcast relies on conversations with reporters who have been on the ground and specialists who have spent years, sometimes decades, studying a particular issue. The result is a clearer, more substantive understanding of what’s happening in India and around the world. You might explore the roots of a regional conflict one episode, and dive into the complexities of a new environmental policy the next. It’s designed for anyone who feels that the daily news skim leaves too many questions unanswered. Tune in for a consistent, deep-dive format that prioritizes context over instant reaction, making sense of the week’s most significant developments through careful analysis and expert insight.
