Benicar (Olmesartan)

Strength(s):  10 mg ; 20 mg ; 40 mg

Active Ingredient: Olmesartan



Olmesartan or Benicar as it is more commonly known, is an angiotensin receptor blocker that is most commonly used to prevent blood vessels from narrowing, lowering blood pressure and improving blood flow.

It is a white crystalline powder that is insoluble in water and slightly soluble in ethanol. It is usually taken orally in the form of film-coated tablets that also contain several inactive ingredients.


Because of its effective property of keeping blood vessels dilated, Benicar is mostly used in the treatment of hypertension in adults and children over 6 years old. It is also used as a medication for strokes, kidney problems, and heart attacks.


The dosage of this medicine will usually vary depending on your response to treatment and medical condition. It should therefore be taken exactly as prescribed by your doctor. The dosage may also be changed occasionally so as to achieve the best results.

When taking this medicine, blood pressure needs to be constantly checked because it can lead to very low blood pressure. If you get sick with diarrhea, vomiting, or sweating, call your doctor immediately.

Even after feeling well, the medication should still be taken as prescribed because hypertension has no immediate symptoms.

Benicar may be taken with or without food.

Side Effects

Use of Benicar could result in a number of possible side effects. These should not be used as reasons to avoid taking the medicine because your doctor has considered the possible side effects and judged that there is more to gain from using the medicine.

Most common side effects are dizziness and lightheadedness that are a result of your body adjusting to the medication. You should, however, tell your doctor if these effects continue for a prolonged period of time.

Additionally, should you experience any of the following effects when taking this medicine, contact your doctor immediately:

– Fainting

– Muscle weakness

– Slow or irregular heartbeat

– Severe diarrhea

– Sighs of kidney problems

Allergic reactions to Benicar are very rare. But if you notice any symptoms of an allergic reaction, get medical help right away. Some possible allergic reactions include rashes, itchiness, swelling of the face, tongue, or throat, troubled breathing, and severe dizziness.

It should be noted that this is not a comprehensive list of possible side effects that could result from the use of Benicar. Should you experience effects that are not listed here, contact your doctor.


Do not take this medicine if you are allergic to olmesartan. You should also let your doctor know of any other allergies that you have because this medicine may contain other inactive ingredients that could possibly cause allergic reactions.

Also tell your doctor your medical history, especially one that entails liver disease, kidney disease, congestive heart failure, and dehydration.

Because this drug may cause dizziness and lightheadedness, you should not drive, use any machinery, or undertake an activity that requires you to be alert until you are certain that you can complete such activities safely. Also avoid alcoholic beverages.

Benicar should also be avoided if you are pregnant. If you become pregnant when taking it, inform your doctor and stop its use. Benicar can cause harm or death to an unborn baby when taken during the second or third trimester. Birth control should therefore be taken if you are taking it.

Where to Buy Benicar
