Introduction

Potassium citrate medication is used to help prevent kidney stones.

What is potassium citrate

Potassium citrate is a medication that is used for many different purposes. This information sheet focuses on its use as a medication to help dissolve kidney stones and prevent them from forming. 

Uricosal is commercially available products that contain potassium citrate and it also contains sugar. If your child has been advised by their doctor not to have medications containing sugar or carbohydrates it is important not to use this product. 

Your child may start with the liquid form of potassium citrate medicine and then switch to tablets when they are older and can swallow tablets easily. 

Ask your doctor or pharmacist for more information about switching to tablets if you think your child is ready.

What is it used for

There may be different reasons why your child is prescribed this medication and one of them is to help dissolve kidney stones and prevent them from forming. 

It is often used along with prescribed special diets (for example, a ketogenic or low salt diet) for children with certain medical conditions or for patients with kidney problems. Using this medication does not change how well the ketogenic diet works.   

It is sometimes used to treat a condition called metabolic acidosis, especially if extra potassium is also required. 

Your child may have regular blood tests, urine tests, and monitoring to ensure the medication is working effectively and safely. 

Be careful if using other medications that have potassium in them, let your doctor and pharmacist know as extra blood test monitoring may be needed.
