About this Medication

What the Medication Is Used For

OLMETEC is used to lower blood pressure in adults and children above 6 years old.

High blood pressure increases the workload of the heart and arteries. If this condition continues for a long time, damage to the blood vessels of the brain, heart, and kidneys can occur, and may eventually result in a stroke, heart or kidney failure. High blood pressure also increases the risk of heart attacks. Reducing your blood pressure decreases your risk of developing these illnesses.

What It Does

OLMETEC contains a drug olmesartan medoxomil which acts to inhibit the naturally occurring hormone, angiotensin II in the human body that causes the blood vessels to constrict. As an angiotensin receptor blocker (ARB), OLMETEC lowers blood pressure by relaxing the blood vessels and as a result blood pressure is lowered. You can recognize an ARB because its medicinal ingredient ends in “SARTAN”.

This medicine does not cure your disease. It helps to control it. Therefore, it is important to continue taking OLMETEC regularly even if you feel fine.

When It Should not be Used

Do not take OLMETEC if you:

  • Are allergic to Olmesartan medoxomil or to any non-medicinal ingredient in the formulation.
  • Have experienced an allergic reaction (angioedema) with swelling of the hands, feet, or ankles, face, lips, tongue, throat,or sudden difficulty breathing or swallowing, to any ARB. Be sure to tell your doctor, nurse, or pharmacist that this has happened to you.
  • Are pregnant or intend to become pregnant. If this is the case, talk to your doctor as soon as possible. Taking OLMETEC during pregnancy can cause injury and even death to your baby.
  • Are breastfeeding. It is possible that OLMETEC passes into breast milk.
  • Are already taking a blood pressure-lowering medicine that contains aliskiren (such as Rasilez) and you have diabetes or kidney disease.

OLMETEC is not recommended for use in children below the age of 6 years.

Warnings and Precautions

Serious Warnings and Precautions

OLMETEC should not be used during pregnancy.
If you discover that you are pregnant while taking OLMETEC, stop the medication and please contact your doctor, nurse, or pharmacist as soon as possible.

BEFORE you use OLMETEC talk to your doctor or pharmacist if you:

  • have experienced an allergic reaction to any drug used to lower blood pressure.
  • have narrowing of a heart valve, heart or blood vessel disease.
  • have diabetes, liver or kidney disease.
  • are on dialysis.
  • are dehydrated or suffer from excessive vomiting, diarrhea, or sweating.
  • are on a low-salt diet.
  • are taking a salt substitute that contains potassium, potassium supplements, or a potassium-sparing diuretic (a specific kind of “water pill” that makes your body keep potassium).
  • are taking a medicine that contains aliskiren, such as Rasilez, used to lower high blood pressure. The combination with OLMETEC is not recommended.
  • are taking an angiotensin converting enzyme inhibitor (ACEI). You can recognize ACEIs because their medicinal ingredient ends in “PRIL”.
  • are less than 18 years old.

OLMETEC can cause severe chronic diarrhea with substantial weight loss (sprue-like enteropathy). It can take months to years for symptoms to develop.

Driving and using machines: Before you perform tasks which may require special attention, wait until you know how you respond to OLMETEC. Dizziness, lightheadedness, or fainting can especially occur after the first dose and when the dose is increased.

The following may interact with OLMETEC:

  • Agents increasing serum potassium, such as a salt substitute that contains potassium, potassium supplements, or a potassium-sparing diuretic (a specific kind of “water pill”).
  • Blood pressure lowering drugs, including diuretics (“water pills”), aliskiren-containing products (e.g. Rasilez), or angiotensin coverting enzyme inhibitors (ACEIs).
  • Lithium used to treat bipolar disease.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs), used to reduce pain and swelling. Examples include ibuprofen, naproxen, and celecoxib (COX-2 Inhibitor).
