Newly added information:

Postmarketing Experience: Non-melanoma Skin Cancer: Hydrochlorothiazide is associated with an increased risk of non-melanoma skin cancer.

The increased risk for SCC in the overall population was approximately 1 additional case per 16,000 patients per year, and for white patients taking a cumulative dose of greater than or equal to 50,000 mg the risk increase was approximately 1 additional SCC case for every 6,700 patients per year.
