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 current medicines and any you start or stop using, especially:
chloral hydrate;
lithium;
phenytoin;
cancer medicine, such as cisplatin;
heart or blood pressure medicine; or
another diuretic, especially ethacrynic acid.
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 interactions are listed in this medication guide.
