Key takeaways
Irbesartan (Avapro) and valsartan (Diovan) are both angiotensin II receptor blockers (ARBs) used to treat high blood pressure. Irbesartan is also used to treat diabetic kidney disease, while valsartan is used to lower the risk of heart-related problems in adults with heart failure or after a heart attack. Both medications are available in generic forms, making them more affordable. Irbesartan is typically taken once a day, whereas valsartan can be taken once or twice a day depending on the condition being treated. Common side effects for both include dizziness and tiredness, but valsartan can also cause stomach pain and a viral infection. Neitehr medication is safe to use during pregnancy and both can raise potassium levels, requiring regular blood work to monitor kidney health.
