Furosemide
Summary
Furosemide is used to treat conditions like high blood pressure and edema, which is swelling due to excess fluid. This can be caused by heart, kidney or liver disease.
Furosemide helps the kidneys remove excess water and salt from the body through urine. This reduces fluid retention and lowers blood pressure.
For adults, the typical starting dose for edema is 20 to 80 mg as a single dose. For high blood pressure, it's 80 mg divided into two doses. For children, it's 2 mg per kg of body weight. Always follow your doctor's specific instructions.
Common side effects include frequent urination, blurred vision, headache, constipation and diarrhea. Serious effects can include hearing loss, rash, difficulty breathing, and electrolyte imbalances.
Furosemide should not be used by patients with an inability to urinate or those allergic to it. It can cause dehydration, electrolyte imbalances and hearing damage. Patients with liver disease, kidney disease or diabetes should use it cautiously.
