Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
If you also take sucralfate, take your furosemide dose 2 hours before or 2 hours after you take sucralfate.
Tell your doctor about all your other medicines, especially:
another diuretic, especially ethacrynic acid;
chloral hydrate;
lithium;
phenytoin;
an injected antibiotic;
cancer medicine, such as cisplatin;
heart or blood pressure medicine; or
salicylates such as aspirin, Nuprin Backache Caplet, Kaopectate, KneeRelief, Pamprin Cramp Formula, Pepto-Bismol, Tricosal, Trilisate, and others.
This list is not complete. Other drugs may interact with furosemide, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
