About Lasix Injection
Lasix Injection, classified as a diuretic medication, is primarily used in cases of hypertensive emergency to swiftly reduce high blood pressure. Additionally, it aids in promptly alleviating edema, which is swelling triggered by an excess of fluid in the body. The medication operates by helping the body eliminate surplus water and salt through urine. Commonly prescribed for individuals with fluid retention due to heart failure, liver, or kidney issues, Lasix Injection is administered intravenously under the supervision of a medical professional. It is essential for patients to have their blood pressure monitored post-administration of this medicine.
