WHO agency classifies medicines as carcinogenic

The International Agency for Research on Cancer (IARC), a WHO body, has classified three widely used medicines as 'carcinogenic to humans' (Group 1).
The medicines are: Hydrochlorothiazide (hypertension), Voriconazole (fungal infections), and Tacrolimus (immunosuppressant for organ transplants).
All three drugs are included in the WHO Model List of Essential Medicines.
Hydrochlorothiazide is linked to squamous cell skin carcinoma and lip cancer.
Voriconazole is associated with squamous cell skin carcinoma in transplant recipients on prolonged therapy due to phototoxic mechanisms.
Tacrolimus is linked to non-Hodgkin lymphoma and post-transplant lymphoproliferative disorder, with limited evidence for leukaemia and skin carcinoma.
IARC classification is a 'hazard identification' and does not imply an immediate need for patients to discontinue treatment without medical consultation.
Concerns exist regarding irrational prescribing, over-the-counter availability, and poor adherence to ethical prescribing practices in India.

All three drugs are included in the WHO Model List of Essential Medicines.
Hydrochlorothiazide is linked to squamous cell skin carcinoma and lip cancer.
Voriconazole is associated with squamous cell skin carcinoma, particularly in transplant recipients on long-term therapy.
Tacrolimus is linked to non-Hodgkin lymphoma and post-transplant lymphoproliferative disorder, with limited evidence for leukaemia and skin carcinoma.
IARC classification is a hazard identification; experts advise against discontinuing treatment without medical consultation.
Concerns exist regarding irrational prescribing, over-the-counter availability, and poor adherence to ethical prescribing practices in India.
