Key takeaways
Telmisartan (Micardis) and valsartan (Diovan) are both angiotensin II receptor blockers (ARBs) used to treat high blood pressure, but they have some differences. Telmisartan is typically taken once a day, while valsartan can be taken once or twice a day depending on the condition being treated. Besides treating high blood pressure, telmisartan is used to lower the risk of heart attack and stroke in certain adults, whereas valsartan is used to lower the risk of hospitalization for heart failure and death after a heart attack. Valsartan is available in both tablet and liquid forms, making it suitable for children. Telmisartan, on the other hand, is not recommended for children. Both medications can cause dizziness and fatigue, but telmisartan is more likely to cause upper respiratory infections and back pain. Both are available as lower-cost generics and should not be used during pregnancy due to potential harm to the unborn baby.
