Introduction
Furosemide, or Lasix, is a diuretic that helps your body get rid of excess fluid and lower blood pressure.
What is Furosemide?
Furosemide, also known as Lasix (other brands are available), belongs to a group of medications known as diuretics.
Diuretics reduce the amount of salt and water in the body and increase the volume of urine.
It is used to help remove excess fluid from the body and can lower blood pressure.
Medication instructions
How to give Furosemide
Give this medicine exactly as your doctor ordered. It can be given with or without food.
If your child requires liquid, use a syringe to accurately measure the dose. Alternatively, if your child requires tablets, they may be crushed and mixed with a small amount of water or a spoon of yoghurt if necessary.
Give your child Furosemide at the same time every day.
Choose times that are easy for you so that you do not miss doses. For older children, they may prefer to take furosemide in the morning and/or early afternoon (if twice a day) to avoid having to get up overnight to use the bathroom.
What to do if your child vomits
- If your child vomits less than 15 minutes after receiving medication, the dose may be repeated.
- If your child vomits more than 15 minutes after receiving medication, you do not need to give them another dose. Wait until the next scheduled dose is due.
What to do if your child misses a dose
- If a dose is missed, give it within 4 hours.
- If it has been more than 4 hours after the usual time, do not give the missed dose. Just give the dose at the next scheduled time.
- Do not double any doses.
