If you are prescribed furosemide (Lasix), your doctor may want you to take it a few days one week, stop and then take it again the next week. For example, a common treatment plan is to take furosemide for two to four consecutive days, stop for the rest of the week and then repeat each week after that. You may be able to stop taking furosemide, a diuretic used to treat edema (fluid retention), when your edema improves.
Furosemide is also used to treat high blood pressure. If this is why you're taking it, your doctor may have you continue indefinitely.
Do not stop taking furosemide without talking to your doctor. However, your doctor may advise you to stop taking furosemide if it causes serious side effects, in which case you may need a different medication.
