- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: aminoglycoside antibiotics such as amikacin and gentamicin (Garamycin); anticoagulants (‘blood thinners’) such as warfarin (Coumadin, Jantoven); cephalosporin antibiotics such as cefaclor, cefadroxil, and cephalexin (Keflex); corticosteroids such as dexamethasone, hydrocortisone (Cortef), methylprednisolone (Medrol), prednisolone (Prelone), or prednisone (Rayos); digoxin (Lanoxin), lithium (Lithobid); and nonsteroidal anti-inflammatory medications such as ibuprofen (Advil, Motrin) and naproxen (Aleve). Your doctor may need to change the doses of your medications or monitor you more carefully for side effects.
- tell your doctor if you have kidney disease. Your doctor may tell you not to take ethacrynic acid.
- tell your doctor if you have or have ever had diabetes, gout, or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking ethacrynic acid, call your doctor.

Ethacrynic Acid Dosage
Ethacrynic acid comes as a tablet to take by mouth. It is usually taken once or twice a day with food or after meals depending on your doctor’s instructions. Take ethacrynic acid at around the same time(s) every day. 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.
Other
Keep all appointments with your doctor and the laboratory. Your doctor may monitor your blood pressure and weight during your treatment and may order blood tests to check your body’s response to ethacrynic acid.
Do not let anyone else take your medicine. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
