Irbesartan/Hydrochlorothiazide Viatris

Irbesartan/Hydrochlorothiazide, the active ingredient in Irbesartan/Hydrochlorothiazide Viatris, is an Angiotensin II receptor blocker / Thiazide diuretic presented as an oral tablet for systemic use. It is employed to lower elevated blood pressure in adult patients with hypertension and is indicated for those whose pressure is not adequately controlled with monotherapy, offering a combined antihypertensive effect.

GNH USA supplies Irbesartan/Hydrochlorothiazide Viatris as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable, quality‑assured medication that meets stringent regulatory standards.

Irbesartan/Hydrochlorothiazide is used to manage hypertension, a condition characterized by elevated arterial pressure. - Hypertension: lowers systolic and diastolic blood pressure, reducing risk of cardiovascular events. - Essential hypertension: provides effective blood pressure control in primary hypertension when monotherapy is insufficient. - Hypertension‑related edema: increases urinary sodium and water excretion to reduce fluid retention.

Like all medicines, Irbesartan/Hydrochlorothiazide may cause unwanted reactions.

Common Side Effects: - Dizziness - Headache - Fatigue - Increased urination

Serious or Rare Side Effects: - Severe electrolyte imbalance (e.g., low potassium) - Acute kidney injury - Allergic reactions such as rash or angioedema

Before prescribing Irbesartan/Hydrochlorothiazide, clinicians should consider several safety aspects. - Renal function: assess kidney function and monitor serum creatinine and electrolytes. - Hyperkalemia risk: avoid use in patients with high potassium levels or those taking potassium‑sparing agents. - Volume depletion: caution in patients prone to dehydration or on high‑dose diuretics. - Pregnancy: contraindicated in the second and third trimesters; avoid use during pregnancy. - Drug interactions: review concomitant medications that affect renal function or electrolyte balance. - Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture and light.

Irbesartan/Hydrochlorothiazide can interact with other medicines, altering its efficacy or safety.

Major Interactions (Avoid): - Concomitant use with other renin‑angiotensin system blockers (ACE inhibitors, other ARBs) – risk of additive renal impairment and hyperkalemia. - Potassium‑sparing diuretics or supplements – may cause dangerous hyperkalemia. - Lithium – increased lithium levels, risk of toxicity.

Moderate Interactions (Monitor Closely): - NSAIDs – may reduce antihypertensive effect and impair renal function. - Cyclosporine or tacrolimus – can increase serum creatinine. - Antidiabetic drugs – diuretic‑induced changes in glucose may require dose adjustment.
