Uses For furosemide
Furosemide injection is used to help treat fluid retention (edema) and swelling that is caused by congestive heart failure, liver disease (cirrhosis), kidney disease, or other medical conditions.

Before Using furosemide
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For furosemide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to furosemide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of furosemide injection in children. However, premature babies are more likely to have unwanted effects (e.g., kidney stones, hearing problems), which may require caution in patients receiving furosemide injection.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of furosemide injection in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving furosemide injection.
