What is Prussian blue?
Prussian blue was originally developed as a dye for use in paints and ink. It is used in medicine to help speed up the body's elimination of certain metals or chemical elements. It works by binding to the metals in the digestive tract to keep the body from absorbing them.
Prussian blue is used to treat people who have been contaminated with radioactive cesium or thallium, or non-radioactive thallium.
Prussian blue may also be used for other purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

How should I take Prussian blue?
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Prussian blue may work best if you take it with food.
Prussian blue is usually taken 3 times per day for at least 30 days. You may need to take several capsules at one time to get the correct dose.
To make swallowing easier, you may open the Prussian blue capsules and sprinkle the medicine into a spoonful of liquid or bland food. Swallow right away without chewing. Do not save the mixture for later use.
Opening a Prussian blue capsule and mixing the medicine with liquid or food may cause a blue discoloration inside your mouth.
After you are treated with Prussian blue, your urine and stools will contain the radioactive materials that this medicine has helped the body eliminate. Use a toilet rather than a urinal and sit on the toilet while urinating. Flush the toilet 3 times with the lid down after use.
Always wash your hands after using the bathroom. Avoid handling any clean-up of your stools or urine without wearing latex rubber gloves. If another person is handling your stools or urine, they should wear gloves, eye protection, and a mask to cover the nose and mouth.
When cleaning any spills of bodily fluid, use only disposable cleaning cloths that can be flushed down a toilet. Ask your doctor or health department how to dispose of any bodily fluid spills that cannot be flushed down a toilet.
Wash any soiled clothing separately from the laundry of other people in your home.
Although Prussian blue helps the body quickly eliminate a radioactive element, this medicine will not treat any symptoms of radiation exposure. You will be given other medications to treat complications of radiation exposure, such as bone marrow suppression or severe infection.
To be sure this medicine is helping your condition, the radiation levels in your urine and stools will need to be checked often. This will help your doctor determine how long to treat you with Prussian blue.
Store Prussian blue capsules in the dark at room temperature. Do not expose this medicine to light.
