Common use
Irbesartan is a widely prescribed angiotensin receptor blocker (ARB) used to treat high blood pressure (hypertension) and to provide kidney protection in patients with type 2 diabetes who have diabetic nephropathy. As an ARB medication, irbesartan works by selectively blocking angiotensin II receptors in blood vessel walls, which prevents the hormone angiotensin II from causing vasoconstriction. This relaxes and widens the blood vessels, allowing blood to flow more freely and effectively lowering blood pressure. When you buy Irbesartan online, you receive a proven antihypertensive medication that not only helps control blood pressure but also offers significant renal protective benefits. Irbesartan is marketed under the brand name Avapro and is available in generic form. Clinical studies have demonstrated that this angiotensin receptor blocker significantly slows the progression of kidney disease in diabetic patients and reduces the risk of cardiovascular events associated with uncontrolled hypertension.

Dosage and direction
Take Irbesartan by mouth once daily, with or without food, as directed by your doctor. The typical starting dose for hypertension is 150 mg once daily, which may be increased to 300 mg daily based on your blood pressure response. For kidney protection in patients with diabetic nephropathy, the recommended maintenance dose is 300 mg once daily. Try to take your medication at the same time each day to maintain consistent blood levels. The full blood pressure-lowering effect of this ARB is usually achieved within 4–6 weeks of initiating treatment. Do not stop taking irbesartan abruptly without consulting your healthcare provider, as sudden discontinuation may cause a rebound increase in blood pressure.

Precautions
Inform your doctor about your complete medical history before starting Irbesartan, especially if you have kidney disease, liver problems, heart failure, coronary artery disease, or are on a low-sodium diet or taking potassium supplements. Avoid becoming dehydrated, particularly during exercise, hot weather, or illness involving vomiting or diarrhea, as dehydration combined with this blood pressure medication may significantly increase the risk of hypotension (dangerously low blood pressure). Patients should have their kidney function and electrolyte levels (particularly potassium) monitored regularly during treatment. If you experience persistent dizziness or lightheadedness, especially when standing up, notify your doctor as your dose may need adjustment. Buy irbesartan from reputable pharmacies to ensure product authenticity and quality.

Contraindications
Do not use Irbesartan if you are allergic to it or any of its components. This angiotensin receptor blocker is strictly contraindicated during pregnancy, particularly during the second and third trimesters, as ARBs can cause serious harm or death to the developing fetus. Irbesartan should not be used in combination with aliskiren in patients with diabetes or moderate-to-severe kidney impairment. Patients with bilateral renal artery stenosis or stenosis of the artery to a solitary kidney should use this medication with extreme caution. Avapro generic and branded forms carry the same contraindications.

Possible side effect
Common side effects of Irbesartan include dizziness, lightheadedness (especially when standing up), fatigue, nasal congestion, and diarrhea. Some patients may experience musculoskeletal pain or upper respiratory symptoms. Serious but less common side effects include signs of kidney dysfunction (such as changes in urination amount, swelling in feet or ankles), hyperkalemia (high potassium levels) which may cause irregular heartbeat or muscle weakness, and significant hypotension (low blood pressure) manifesting as severe dizziness or fainting. Rare allergic reactions including skin rash, itching, swelling of the face or throat, and difficulty breathing require immediate medical attention. Report any unusual or persistent symptoms to your healthcare provider promptly.

Drug interaction
Irbesartan may interact with several medications. Potassium supplements, potassium-sparing diuretics (such as spironolactone), or salt substitutes containing potassium may increase the risk of hyperkalemia when used alongside this ARB. Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen may reduce the blood pressure-lowering effect of irbesartan and may worsen kidney function. Lithium levels may become elevated when used with angiotensin receptor blockers, requiring careful monitoring. Other antihypertensive medications may have additive effects on blood pressure. Always inform your doctor about all prescription medications, over-the-counter drugs, vitamins, and herbal supplements you are taking.

Missed dose
If you miss a dose of Irbesartan, take it as soon as you remember on the same day. If it is almost time for your next scheduled dose, skip the missed one and resume your regular dosing schedule. Do not double the dose to make up for a missed one, as this may cause your blood pressure to drop too low.

Overdose
Symptoms of Irbesartan overdose may include severe dizziness, fainting, or dangerously low blood pressure, and rapid or irregular heartbeat. Seek immediate emergency medical attention if an overdose is suspected. Treatment is generally supportive and may include intravenous fluids and monitoring of vital signs. Irbesartan is not significantly removed by hemodialysis.

Storage
Store Irbesartan at room temperature between 20–25°C (68–77°F), away from moisture and heat. Keep the medication in its original packaging, tightly closed, and out of reach of children and pets. Do not use the tablets after the expiration date printed on the label.
