What is sodium picosulfate used for?

Sodium picosulfate is commonly used for constipation and before some surgery or medical examinations.

How should I take sodium picosulfate?

Sodium picosulfate is usually given one each day, at bedtime. This drug is taken by mouth.

If sodium picosulfate has been prescribed for your child, follow carefully the instructions you are given, as your doctor will adjust the dose according to their age and needs.

Sodium picosulfate should only be used for a short time. This is because your bowel can start to rely on this type of laxative to make it work rather than working on its own. If you are still constipated after taking it for five days, you should speak with your doctor.

How do I store sodium picosulfate?

Sodium picosulfate is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store sodium picosulfate in the bathroom or the freezer. There may be different brands of sodium picosulfate that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush sodium picosulfate down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
