Uses

Olmesartan is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Olmesartan belongs to a class of drugs called angiotensin receptor blockers (ARBs). It works by relaxing blood vessels so that blood can flow more easily.

Side Effects

Dizziness or lightheadedness may occur as your body adjusts to the medication. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: fainting, symptoms of a high potassium blood level (such as muscle weakness, slow/irregular heartbeat), signs of kidney problems (such as change in the amount of urine), severe/persistent diarrhea.

Usuage

Take this medication by mouth as directed by your doctor, usually once daily with or without food. The dosage is based on your medical condition and response to treatment.

If you are using the liquid form of this medication, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

If you also take certain drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine, colesevelam, colestipol), take olmesartan at least 4 hours before any of these medications.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
