What Kaluril is used for

Kaluril is used to:
decrease swelling (oedema) of the ankles, feet or legs due to certain heart problems
reduce build-up of fluid in the abdomen (ascites) due to liver disease
lower high blood pressure (hypertension)
Kaluril is a fluid tablet or diuretic.It reduces the amount of excess fluid in the body by increasing the amount of urine produced.Kaluril helps reduce oedema, fluid build-up and high blood pressure by making your kidneys pass more water and salt.
Kaluril may be taken alone or in combination with other medicines to treat your condition.
It is especially useful when taken together with certain other diuretics, which cause loss of potassium from the body.Unlike these other diuretics, Kaluril retains potassium and is able to maintain a normal potassium level in the blood.
Ask your doctor if you have any questions about why Kaluril has been prescribed for you.
Your doctor may have prescribed Kaluril for another reason.
Kaluril is available only with a doctor’s prescription.
There is no evidence that Kaluril is addictive.
