Why is this medication
prescribed?
Olmesartan
is used alone or in combination with other medications to treat high
blood pressure. Olmesartan is in a class of medications called
angiotensin II receptor antagonists. It works by blocking the action of
certain chemicals that tighten the blood vessels, so blood flows more
smoothly.

used?
Olmesartan
comes as a tablet to take by mouth. It is usually taken once a day with
or without food. To help you remember to take olmesartan, take it
around the same time every day. Follow the directions on your
prescription label carefully, and ask your doctor or pharmacist to
explain any part you do not understand. Take olmesartan exactly as
directed. Do not take more or less of it or take it more often than
prescribed by your doctor.
Your
doctor may start you on a low dose of olmesartan and gradually increase
your dose, not more than once every 2 weeks.

weeks before you feel the full benefit of olmesartan. Continue to take
olmesartan even if you feel well. Do not stop taking olmesartan without
