Indications & Clinical Uses

Irbesartan/Hydrochlorothiazide is used to manage high blood pressure and related cardiovascular conditions.

  • Essential hypertension: reduces systolic and diastolic pressure to target levels.
  • Secondary hypertension: assists in controlling blood pressure when caused by other medical conditions.
  • Hypertension in patients with diabetes: helps achieve blood pressure goals while providing renal protective benefits.

How It Works

  • Irbesartan selectively blocks angiotensin II type 1 (AT1) receptors, preventing vasoconstriction and aldosterone release. Hydrochlorothiazide inhibits sodium‑chloride reabsorption in the distal convoluted tubule, increasing urinary excretion of water and electrolytes, which lowers plasma volume and contributes to blood pressure reduction.

Side Effects

Common Side Effects

  • Dizziness or light‑headedness, especially after the first dose.
  • Increased urination or mild dehydration.
  • Electrolyte disturbances such as low potassium or sodium.
  • Headache.
  • Fatigue.
  • Mild gastrointestinal upset.

Serious or Rare Side Effects

  • Severe hypotension or syncope.
  • Acute kidney injury or worsening renal function.
  • Hyperkalemia, particularly when combined with potassium‑sparing agents.
  • Angioedema or severe allergic reactions.
  • Liver function abnormalities.
  • Blood disorders such as leukopenia or thrombocytopenia.

Precautions & Warnings

Before starting therapy, consider the following precautions:

  • Pregnancy: contraindicated in pregnancy (Category D) due to risk of fetal toxicity.
  • Renal impairment: monitor kidney function and adjust dosage if necessary.
  • Electrolyte balance: check serum potassium and sodium regularly.
  • Concomitant diuretics: assess risk of excessive diuresis and electrolyte loss.
  • Gout: may increase serum uric acid; monitor patients with a history of gout.
  • Store at ambient temperature: keep below 25°C, retain in original packaging, protect from moisture.

Avoid Interactions

Irbesartan/Hydrochlorothiazide may interact with several medicines.

Major Interactions (Avoid)

  • Aliskiren in patients with diabetes or renal impairment: risk of renal dysfunction.
  • Potassium‑sparing diuretics or supplements: may cause dangerous hyperkalemia.
  • Lithium: increased lithium levels leading to toxicity.

Moderate Interactions (Monitor Closely)

  • NSAIDs: may reduce antihypertensive effect and impair renal function.
  • ACE inhibitors or other ARBs: additive blood pressure lowering and potassium rise.
  • Antidiabetic agents: may require dose adjustment due to enhanced hypoglycemic effect.

Frequently Asked Questions

Irbesartan + Hidroclorotiazida Sandoz is indicated for the treatment of hypertension. It combines an angiotensin II receptor blocker with a thiazide diuretic to lower blood pressure in adults, helping to reduce the risk of cardiovascular complications associated with high blood pressure.

Irbesartan blocks AT1 receptors, preventing angiotensin II‑mediated vasoconstriction and aldosterone release. Hydrochlorothiazide, the diuretic component, inhibits sodium‑chloride reabsorption in the distal tubule, promoting water loss and decreasing plasma volume. Together they provide complementary mechanisms to lower blood pressure.

The specific dose is determined by the prescribing clinician based on the patient’s medical condition, response to therapy, and other individual factors. Healthcare professionals adjust the dosage to achieve optimal blood‑pressure control while monitoring safety.

The product is classified as Pregnancy Category D, indicating evidence of risk to the fetus and it should not be used during pregnancy. Safety during breastfeeding has not been established, and a healthcare provider should be consulted before use in nursing mothers.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details, and any necessary import documentation.

Compared with monotherapy agents, the Irbesartan/Hydrochlorothiazide combination offers dual action—vascular relaxation from the ARB and diuresis from the thiazide—often achieving better blood‑pressure control at lower individual doses. This can reduce pill burden versus separate prescriptions, though individual response and tolerance vary.

Store the tablets at ambient temperature, preferably below 25 °C. Keep them in the original container, protect from moisture and direct sunlight, and ensure they are out of reach of children.

The medication is taken orally, usually once daily, with or without food, as directed by a healthcare professional. Swallow the tablet whole with a full glass of water; do not crush or chew unless specifically instructed.

Serious risks include severe hypotension, acute kidney injury, hyperkalemia, and rare cases of angioedema. Patients should be monitored for signs of these conditions, especially when initiating therapy or when combined with other drugs that affect renal function or electrolyte balance.

The combination is contraindicated in patients with known hypersensitivity to irbesartan, hydrochlorothiazide, or any component of the formulation. It should also be avoided in pregnant women and in individuals with severe renal impairment or anuria.
