Olmesartan encourages better blood flow. So if you have high blood pressure, taking olmesartan will prevent your blood vessels from narrowing while lowering your blood pressure.

This medication may also be combined with other blood pressure medication.

To make sure your blood pressure is stabilized, apply olmesartan as instructed by your doctor and prescription label. 

You can take this medication with or without food. And in either case, keep taking it as instructed, even when you feel well. Typically, high blood pressure will show no symptoms. You might not even notice you have the condition without medical help. But it may be a condition that recurs frequently without medication controlling it. So you should continue taking olmesartan until your doctor says otherwise.

When not using this medication, please store it in a place at room temperature where there’s no moisture or heat.

While on olmesartan, you will need to get your blood pressure checked often.

Checking your blood pressure regularly will give you a better idea of how well it’s stabilizing. And you’ll be able to tell if the medication is giving you very low blood pressure. Other ways to tell if you have excessive low blood pressure are when you have been sweating a lot more or feeling sick with vomiting or diarrhea. Those last few signs are ones you should report right away to your doctor.

Don’t forget to let the doctor know if you are planning on becoming pregnant or are dealing with diabetes medications. Taking olmesartan is deadly for your unborn baby and can react poorly with diabetes medication that contains aliskiren.

There are not many common side effects that come with olmesartan, mainly just dizziness. So if you experience any of the following, call your doctor at once: light-headedness; incredibly minimal urination; severe diarrhea with weight loss; chest pain; fast or slow heart rate; swollen hands, feet, or facial area; nausea; weakness; loss of movement; hives; or breathing difficulty.
