Description
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.
Furosemide injection is also used to treat edema (swelling) in patients with chronic heart failure or chronic kidney disease (eg, nephrotic syndrome).
Furosemide belongs to a group of medicines called loop diuretics or "water pills". It works by acting on the kidneys to increase the flow of urine.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:

Before Using
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 this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of furosemide injection to treat fluid retention and swelling in children. However, premature babies are more likely to have unwanted effects (eg, kidney stones, hearing problems), which may require caution in patients receiving furosemide injection.
Appropriate studies have not been performed on the relationship of age to the effects of furosemide injection to treat edema (swelling) in the pediatric population. Safety and efficacy have not been established.
Geriatric
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.
Breastfeeding
Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
