How does this medication work? What will it do for me?
Olmesartan belongs to the class of medications called angiotensin II receptor blockers. It is used to reduce blood pressure by blocking the actions of a chemical (angiotensin II) that causes blood vessels to constrict or tighten. It is used to treat mild to moderate high blood pressure. Your blood pressure may start to decrease within 1 to 2 weeks of starting this medication. Olmesartan may be used alone or in combination with a diuretic (water pill).
When blood pressure is allowed to remain high for a long time, the blood vessels of the heart, kidneys, and brain may become damaged. This puts a person at increased risk for heart attack and stroke as well as kidney failure and blindness. Keeping blood pressure in the normal range can reduce the risk for these conditions.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles.

For pediatric patients, between the ages of 6 and 16 years of age, the usual dose is based on weight. Children weighing between 20 kg to less than 35 kg should receive 10 mg once daily up to a maximum of 20 mg daily. The dose for children weighing more than 35 kg is 20 mg once daily. Olmesartan may be taken with or without food, but should be taken in the same manner each day.

Are there any other precautions or warnings for this medication?
Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take this medication.
Drowsiness/reduced alertness: Blood pressure medications may cause drowsiness or dizziness. Avoid driving or operating machinery until you know whether the medication affects you in this way.
Kidney disease: Olmesartan may affect the function of the kidneys, causing decreased kidney function, kidney failure, or possibly death. Certain people have experienced changes in kidney function (e.g., people with narrowed blood vessels in their kidneys, or those with severe congestive heart failure). The use of diuretics (water pills), nonsteroidal anti-inflammatory drugs (NSAIDs), or aliskiren may further increase risk of kidney problems for people already at risk for this problem. If you have kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver disease: Liver disease may cause olmesartan to be cleared more slowly from the body, resulting in increased side effects. If you have liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Low blood pressure: Occasionally, a greater-than-expected drop in blood pressure occurs after taking this medication. It is more likely to occur if you are taking additional diuretics (water pills), or aliskiren, have reduced salt intake, are on dialysis, have diarrhea, or are vomiting.
Your doctor may recommend that you have your blood pressure tested more often in these situations. To reduce the risk of dizziness, people with low blood pressure or those just starting to take this medication should stand or sit up slowly when getting up from a lying down or sitting position. If low blood pressure causes you to faint or feel lightheaded, contact your doctor.
Pregnancy: Babies born to mothers who took olmesartan during pregnancy may develop birth defects. If you become pregnant while taking this medication, stop taking the medication and contact your doctor immediately.
Breast-feeding: It is not known if olmesartan passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Do not breast-feed while you are taking this medication.
Children: The safety and effectiveness of this medication have not been established for children less than 6 years of age.
