मेटोलाज़ोन और टॉरसेमाइड का इंटरैक्शन

Other Antihypertensive Drugs When metolazone tablets, USP, are used with other antihypertensive drugs, particular care must be taken to avoid excessive reduction of blood pressure, especially during initial therapy.

WARNINGS Rapid Onset Hyponatremia And/Or Hypokalemia Rarely, the rapid onset of severe hyponatremia and/or hypokalemia has been reported following initial doses of thiazide and non-thiazide diuretics.

Serum potassium should be determined at regular and appropriate intervals, and dose reduction, potassium supplementation or addition of a potassium-sparing diuretic instituted whenever indicated.

Concomitant Therapy Lithium In general, diuretics should not be given concomitantly with lithium because they reduce its renal clearance and add a high risk of lithium toxicity.

Drug Interactions Diuretics Furosemide and probably other loop diuretics given concomitantly with metolazone can cause unusually large or prolonged losses of fluid and electrolytes (see WARNINGS ).

Ototoxicity Tinnitus and hearing loss (usually reversible) have been observed with loop diuretics, including torsemide.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Reduced diuretic, natriuretic, and antihypertensive effects; risk of renal impairment.

Organic Anion Drugs: May decrease diuretic activity of torsemide.

The antihypertensive and diuretic effects of torsemide can be reduced by NSAIDs.

Monitor diuretic effect and blood pressure when used in combination with CYP2C9 inhibitor or inducer.
