It is a high dose and usually used to get rid of fluid from the body in certain conditions eg congestive heart failure etc quickly. Under careful supervision it will not ruin your kidneys.

If the kidney function is very weak (low GFR), Lasix dose has to be high in order to get enough level for the desired effect at the loop of Henle, therefore no ill effects on the kidneys. Rarely, the high dose of Lasix may cause ototoxicity (hearing impairment).
