What EDECRIN is used for

EDECRIN helps to reduce the amount of fluid in the body for people who have:

  • swelling of the ankles, feet and legs, which is called oedema
  • fluid accumulation in the lungs, which is called pulmonary oedema
  • fluid accumulation in the stomach area (which is also called ascites) due to liver disease

EDECRIN is also used in children, over 2 years old, to remove fluid that occurs in some heart and kidney conditions.

EDECRIN belongs to a group of medicines called diuretics or fluid tablets.

It works by making your kidneys pass more water and salt from the body.

How much to take

Most people take between 50 mg and 150 mg per day, which is 2 to 6 tablets per day. If you are taking more than two tablets per day, your dose will be divided into two doses per day.

EDECRIN may increase the amount of water (urine) you pass and also the number of times you go to the toilet.
