What is irbesartan 300 mg used for?
Irbesartan 300 mg is a prescription-strength dose of irbesartan, an angiotensin II receptor blocker (ARB). It’s used to treat high blood pressure (hypertension) and to help protect the kidneys in certain patients with diabetic kidney disease.
How does the 300 mg dose fit typical irbesartan regimens?
A common starting dose for irbesartan in hypertension is lower than 300 mg, with clinicians adjusting based on blood-pressure response and tolerability. In practice, 300 mg is often used when a higher daily dose is needed to reach target blood-pressure goals.
How should patients take irbesartan 300 mg?
Irbesartan is usually taken once daily. Patients should follow their prescriber’s instructions about timing and whether to take it with or without food.
What side effects are most commonly reported with irbesartan?
Common side effects can include dizziness or lightheadedness. Like other ARBs, it can also affect kidney function and potassium levels, so lab monitoring is important for many patients—especially those with kidney disease or those taking other medicines that raise potassium.
What labs or safety monitoring are important with irbesartan 300 mg?
Clinicians commonly monitor kidney function (creatinine/eGFR) and potassium after starting or changing an ARB dose. Monitoring may be more frequent in people with chronic kidney disease, dehydration, or those taking additional medications that affect the kidneys or potassium.
Who should avoid irbesartan or use extra caution?
Extra caution is typically needed for people with significant kidney impairment, high potassium (hyperkalemia), or those on medicines that can raise potassium. It is also generally not used in pregnancy, because ARBs can harm the fetus.
What happens if kidney function worsens after starting 300 mg?
It’s relatively common for ARBs to cause a rise in creatinine early in treatment, especially in patients with kidney disease or dehydration. Clinicians decide whether the change is acceptable, whether to adjust dose, or whether to stop the drug depending on severity and trends.
Is irbesartan 300 mg available as a generic?
Irbesartan has long been off-patent in most markets, so 300 mg tablets are commonly available as generics from multiple manufacturers.

What other conditions or medicines commonly interact with irbesartan 300 mg?
People taking diuretics, potassium supplements, salt substitutes containing potassium, or other blood-pressure medicines may need closer monitoring. Combining ARBs with certain kidney-related or potassium-raising therapies can increase the risk of kidney-related lab changes.
Price and availability: what affects the cost of irbesartan 300 mg?
Cost depends largely on whether the tablet is branded or generic, the manufacturer, local pharmacy pricing, and insurance formulary status.
