Common side effects include dizziness, upper respiratory tract infections, nausea, diarrhea, and tiredness.[2] Severe side effects may include kidney problems, electrolyte problems, and allergic reactions.[2] Use during pregnancy may harm the baby.[2] Telmisartan works by blocking the effects of angiotensin II while hydrochlorothiazide works by decreasing the kidneys' ability to retain water.[2]

The combination was approved for medical use in the United States in November 2000,[6][7] and in the European Union in April 2002.[3][4] The combination is on the World Health Organization's List of Essential Medicines.[8] It is available as a generic medication.[5]
