Ethacrynate sodium is used to reduce extra fluid in the body (edema) caused by conditions such as congestive heart failure, liver disease, kidney disease, and cancer. Getting rid of extra water helps to reduce fluid in the lungs so that you can breathe easier. It also helps to decrease swelling of the arms, legs, and stomach/abdomen. This medication is known as a diuretic (the same kind of drug as a "water pill"). It causes your body to get rid of extra water by increasing the amount of urine you make. This injectable form of ethacrynate sodium is used when a similar drug cannot be taken by mouth or when extra water must be removed quickly, especially in patients with severe medical conditions.
This medication is given by injection into a vein by a health care professional. It should not be injected into a muscle or under the skin because pain and irritation at the injection site may occur. Dosage is based on your medical condition and response to treatment.
