About Furosemide
Furosemide contains furosemide. Its medication class is loop diuretic. It may be used for fluid retention from heart, kidney or liver conditions and high blood pressure in selected treatment plans, depending on the exact product, diagnosis and the person’s health profile. It makes the kidneys excrete more sodium and water by acting in the loop of Henle.
Whether Furosemide is appropriate depends on the diagnosis, exact product and strength, health history, other medicines and available follow-up. A general guide cannot determine whether this treatment is right for you.
