View full FDA label ↗Losartan is a medication used to treat high blood pressure in adults and children over 6 years old, and it can also help protect the kidneys in people with type 2 diabetes. It works by blocking a substance in the body that causes blood vessels to tighten, which helps relax the blood vessels and lower blood pressure. You typically take it as a tablet once a day, starting with a dose of 50 mg, which can be increased to a maximum of 100 mg if needed. It's important to know that losartan should not be taken if you are allergic to it or its ingredients. Additionally, if you are taking a medication called aliskiren and have diabetes, you should not use losartan.
