Therefore, it is important that you are closely monitored by your doctor while taking this medication. Tell your doctor right away if you become very thirsty or confused, or develop muscle cramps or weakness.
Lasix tablets are a loop diuretic (water pill) that prevent your body from absorbing too much salt and allow the salt to be passed to your urine.
