I read that lasix (furosemide) is not for long term, that you need to have blood test to see if kidneys are being effected, how long is it safe to use lasix (furosemide)?

Lasix (furosemide): The use of Lasix (furosemide) needs to be monitored in a ll who use it. It can be used looming term if monitored and not causing problems.

Lasix (furosemide): Lasix (furosemide) is a safe drug as long as you are being monitored by your doctor while you are taking the medication. For some disease states, patients stay on the drug for many years. The drug reduces the body's free water volume and causes wasting of some electrolytes. Your physician will need to monitor your weight, blood pressure, physical exam, and labs (kidney function and electrolytes).
