For what purpose is furosemide primarily used?

Furosemide is primarily used to treat fluid retention and swelling, which is medically referred to as edema. This diuretic works by inhibiting the reabsorption of sodium and chloride in the ascending loop of Henle in the kidney, leading to increased urine production. This action helps to reduce the volume of fluid in the body, which is particularly beneficial for patients experiencing conditions such as heart failure, liver disease, or kidney disorders, where excess fluid can accumulate.

While furosemide can have an indirect effect on blood pressure by reducing fluid overload, its primary indication is for managing edema rather than solely for lowering blood pressure. It does not have analgesic properties, meaning it does not relieve pain, nor does it play a role in preventing blood clots. Thus, its main application is firmly centered around controlling fluid retention and alleviating swelling.
