Lasix is a diuretic treatment drug that is effective in treating water retention issues or edema. Edema is the buildup of water in the body that is caused by varying conditions. These underlying conditions must be treated to prevent any buildup from occurring. As a remedy to any fluid buildup, if you buy Lasix, you will be able to remedy the condition. However, even if you buy Lasix, which is an effective remedy for edema, it will not cure the condition, as it is only a temporary remedy for the water retention issue.
