Why is this medication prescribed?

Ethacrynic acid, a 'water pill,' is used to treat high blood pressure and fluid retention caused by various medical problems. It causes the kidneys to get rid of unneeded water and salt from the body into the urine.

This medicine is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medication be used?

Ethacrynic acid comes as a tablet to take by mouth. It usually is taken once or twice a day with food. If you take ethacrynic acid once a day, take it with breakfast in the morning. If you take it twice a day, take it in the morning and in the afternoon to avoid going to the bathroom during the night. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ethacrynic acid exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Ethacrynic acid controls high blood pressure but does not cure it. Continue to take ethacrynic acid even if you feel well. Do not stop taking ethacrynic acid without talking to your doctor.

Are there other uses for this medicine?

Ethacrynic acid is also used to treat high blood pressure and a certain type of diabetes insipidus that does not respond to other medicines. Talk to your doctor about the possible risks of using this medicine for your condition.
