Telmisartan belongs to a class of drugs called angiotensin receptor blockers (ARBs). It works by relaxing blood vessels so blood can flow more easily.
The dosage is based on your medical condition and response to treatment.

Tell your doctor if your condition does not improve or if it worsens (such as your blood pressure readings remain high or increase).
