New research has revealed troubling information about the world's most popular blood pressure medicine.

The study shows hydrochlorothiazide lowers blood pressure by only about half as much as common alternatives like beta blockers and ace inhibitors.

Researchers say the drug is giving patients a false sense of security.

High blood pressure affects about a third of adults in the U.S.

The study is published in the Journal of the American College of Cardiology.
