Hydrochlorothiazide: risk of non-melanoma skin cancer, particularly in long-term use

November 2018 - Studies have shown a dose-dependent increased risk of non-melanoma skin cancer with exposure to increasing cumulative doses of Hydrochlorothiazide (contained in some combination products used for high blood pressure). Patients taking Hydrochlorothiazide should:

• Regularly check for and report any new or changed skin lesions or moles
• Limit their exposure to sunlight and UV rays and use adequate protection when exposed to sunlight and UV rays to minimise the risk of skin cancer
• Make an appointment to discuss alternative options to the use of hydrochlorothiazide if you would like to and particularly if you have had a previous skin cancer.
