Angiotensin receptor blockers (ARBs) start lowering blood pressure within 1 to 4 hours of the first dose. When you start an ARB, it takes anywhere from 2 to 4 weeks to see the most effect. Sometimes your doctor will raise your dose if you are not meeting your blood pressure goals on the starting dose.
Each person is different. There are 8 ARBs your doctor can choose for you. Your doctor will work with you to find the best medicine and the lowest dose that helps you meet your blood pressure goals. So, stick with the plan and take your pill daily.
ARBs, 2 to 4 weeks to reach their peak!
