Benicar Dosages: Customized High Blood Pressure Treatment Options

High blood pressure, also known as hypertension, is one of the most common cardiovascular diseases affecting millions of people worldwide. One of the effective means to combat this condition is Benicar, a medication that has earned the trust of doctors and patients alike due to its efficacy and safety.

Benicar: Mechanism of Action

What is Benicar?

Benicar, scientifically known as olmesartan medoxomil, belongs to a class of drugs known as angiotensin II receptor antagonists. These drugs work by blocking the action of angiotensin II, a substance in the body that causes blood vessels to narrow. As a result, Benicar helps relax blood vessels, which lowers blood pressure and improves blood flow.

Benicar: Available Forms and Dosages

Benicar (olmesartan medoxomil) is produced in tablet form for oral administration. The available dosages of Benicar vary to allow for customized treatment based on the patient's needs and doctor's recommendations. The typical dosages include:

  • 5 mg – This initial dose may be recommended as a starting point in treatment or for patients who require a lower dose due to medical conditions or age.

  • 20 mg – Most commonly prescribed standard dose for adult patients beginning treatment for high blood pressure.

  • 40 mg – The maximum recommended dose for effective blood pressure control in adults.

It is important to note that the dosage of Benicar should be individualized based on the patient's response to treatment and tolerance of the drug. A doctor may decide to start treatment with a low dose and gradually increase it to minimize the risk of side effects and determine the most effective and safe dose for the patient.

Patients should always take Benicar exactly as prescribed by their doctor, without changing the dose without consulting a healthcare professional.

Benefits of Benicar

Using Benicar to treat high blood pressure offers several advantages. Firstly, it provides long-term control of blood pressure, reducing the risk of heart attacks, strokes, and kidney failure. Secondly, Benicar is well tolerated by most patients, with a minimal risk of side effects.

Side Effects and Precautions

While Benicar is effective in treating high blood pressure, it may cause side effects in some patients. Common side effects include:

  • Dizziness or lightheadedness, especially when standing up from a sitting or lying position

  • Fatigue

  • Nausea

  • Diarrhea

  • Headaches

Less common but more serious side effects may include:

  • Kidney problems, including an increase in blood creatinine levels

  • Severe allergic reactions, manifesting as swelling of the face, lips, tongue, or throat, which may cause difficulty breathing

  • A decrease in blood pressure too much, especially after the first dose

  • Changes in blood electrolytes (such as high potassium levels)

Precautions Before taking Benicar, it's important to discuss your full medical history with your healthcare provider, especially if you have:

  • Kidney disease or kidney problems

  • Liver disease

  • Dehydration or electrolyte imbalances

  • If you are pregnant or plan to become pregnant. Benicar is not recommended during pregnancy, especially in the second and third trimesters, as it can cause injury and even death to the developing fetus.

  • If you are breastfeeding or plan to breastfeed. It's unclear if Benicar passes into breast milk.

Interactions Benicar can interact with other medications, which can either diminish its efficacy or increase side effects. Inform your doctor about all the medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements. Specifically, pay attention to:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the blood pressure-lowering effects of Benicar.

  • Diuretics (water pills) and other blood pressure medications may increase the risk of low blood pressure.

  • Lithium, a medication used for bipolar disorder, may have increased levels when taken with Benicar, leading to lithium toxicity.

Monitoring Regular monitoring by your healthcare provider is necessary to check your body's response to Benicar. This may include blood pressure checks, kidney function tests, and monitoring for other potential side effects

Why a Doctor's Consultation is Necessary

Consulting a doctor is crucial before starting any medication, including Benicar, for several reasons. Firstly, a healthcare professional can accurately diagnose high blood pressure and determine if Benicar is the most appropriate medication for your condition. Secondly, doctors can consider your medical history, potential drug interactions, and specific health needs to tailor the treatment plan. This personalized approach ensures the medication is both safe and effective for you.

Where to Buy

Benicar can be purchased at both physical pharmacies and through legitimate online pharmacy platforms. It's important to ensure you are buying from a reputable source to guarantee the quality and authenticity of the medication. In many regions, Benicar requires a prescription, so you may need to provide this documentation when purchasing the medication.

Can Online Pharmacies Be Trusted When Purchasing Such a Medication?

Yes, online pharmacies can be trusted to purchase medication like Benicar, provided they are reputable and properly regulated. Look for online pharmacies that require a prescription, are certified by a national or regional regulatory authority, and have clear contact information and privacy policies. However, caution is advised as the internet does host some illegitimate pharmacies selling counterfeit medications. Always verify the credibility of the online pharmacy before making a purchase.

How to Take Benicar?

Benicar is usually taken once a day, with or without water. It's important to take the medication exactly as prescribed by your doctor, without increasing or decreasing the dose without consultation. Also, it's not recommended to stop taking the medication without discussing it with your healthcare provider first, as this can lead to an increase in blood pressure.


Benicar represents a powerful tool in the fight against high blood pressure, offering patients a reliable and safe way to manage their condition. Always consult with your doctor before starting any new medications to ensure they are suitable for your health and lifestyle.
