Metolazone is a thiazide-like diuretic. It helps the kidneys remove extra salt and water and keeps working even when kidney function is reduced.

What Metolazone Is Used For

Fluid retention (oedema) in heart failure
Oedema in kidney disease
High blood pressure
Resistant fluid build-up, with loop diuretics

Common Side Effects

Low potassium or sodium
Dizziness
Dehydration
Muscle cramps
Raised blood sugar or uric acid

Precautions

Metolazone is strong, especially with other diuretics, so your doctor will check blood salts and kidney function. Report severe dizziness, confusion or muscle weakness. Tell your doctor if you have gout or diabetes.
