  • This medicine may cause the body to lose potassium. Furosemide is often given with another diuretic called spironolactone to stop the loss of potassium. Your doctor may order bloodwork to check sodium and potassium levels.
  • Your doctor may suggest your child to eat/drink food that contain more potassium (such as orange juice or bananas). Please ask your doctor because extra potassium may not be needed.
  • Hold the dose if your child is not eating or drinking well.
  • This medication can lower blood pressure. Ask your child to get out of bed or stand up slowly.
  • Furosemide may cause the skin to burn in the sun. Make sure your child has plenty of sun protection with a hat, clothing and sunscreen with SPF 15.
  • Check with your doctor or pharmacist before starting any new medications, over the counter medications, or herbal products.
