Ethacrynic acid is a prescription water pill. It helps your body get rid of extra water and salt to reduce swelling caused by heart, kidney, or liver conditions.

Yes, in rare cases, this medicine can cause ringing in the ears or hearing loss. Contact your doctor right away if you notice any changes in your hearing.

What should I do if I miss a dose?

Can I stop taking the medicine when my swelling goes down?
