Irbesartan Overview

Irbesartan is an ARB, or angiotensin II receptor blocker, used to treat hypertension and protect the kidneys in patients with diabetes and nephropathy. By blocking a substance that tightens blood vessels, Irbesartan helps relax blood vessels, lower blood pressure, and increase the blood and oxygen supply to the heart. It is available in tablet form with 75, 150, and 300 mg strengths. It is typically taken once daily, with or without food. 

For adults, the initial recommended dose for hypertension is usually 150 mg daily, which may be increased to 300 mg. For diabetic nephropathy, the standard dose is 300 mg daily. This medication is not recommended for children under 18 years old. Geriatric patients may require a lower dose due to slower drug processing.

Common side effects include diarrhea, dizziness, heartburn, and tiredness. Severe side effects can include allergic reactions, kidney problems, high potassium levels, liver issues, and low blood pressure. 

Patients should avoid taking Irbesartan if pregnant or planning to become pregnant. Missed doses should be taken as soon as remembered, but double dosing should be avoided. In case of a medication overdose, seek immediate medical help. Store Irbesartan at room temperature, away from light, moisture, and heat. Do not freeze or store in the bathroom. Keep out of reach of children and pets. Proper disposal of unused medication is essential, and a medicine take-back program is recommended. See your doctor or healthcare provider if you have any concerns or questions regarding using Irbesartan.

How Does Irbesartan Work?

Irbesartan is an ARB or angiotensin II receptor blocker used to treat high blood pressure & protect the kidneys from damage due to diabetes. It blocks a substance in the body that causes blood vessels to tighten. As a result, it relaxes blood vessels, reducing blood pressure and increasing the oxygen and blood supply to the heart. By allowing the kidneys to eliminate extra water and salt, Irbesartan helps improve kidney function.

Frequently Asked Questions

Can Irbesartan be used in patients with renal impairment?

Irbesartan can be used in patients with renal impairment, but dosage adjustments may be necessary depending on the severity of the impairment. Monitoring kidney function regularly is crucial, as Irbesartan can affect renal function, particularly in patients with existing kidney issues.

How does Irbesartan interact with potassium supplements or potassium-sparing diuretics?

Irbesartan can increase potassium levels in the blood. When taken with potassium supplements or potassium-sparing diuretics, there is a risk of hyperkalemia or high potassium levels. Patients should regularly monitor their potassium levels and consult their physician or healthcare provider before taking these supplements or medications concurrently.

What are the long-term effects of taking Irbesartan?

Long-term use of Irbesartan has been shown to effectively manage hypertension and protect kidney function in patients with diabetes mellitus type 2 & nephropathy. However, long-term usage requires regular monitoring of kidney function, potassium levels, and blood pressure to avoid potential adverse effects such as hyperkalemia and renal impairment.

Is Irbesartan effective for heart failure treatment?

Irbesartan is sometimes used off-label to treat heart failure, particularly in patients who cannot tolerate angiotensin-converting enzyme (ACE) inhibitors. However, it is primarily indicated for hypertension and diabetic nephropathy. A healthcare professional should evaluate the effectiveness and safety of Irbesartan for heart failure on a case-by-case basis.
