WHY is this medicine prescribed?

Sodium zirconium cyclosilicate is used to treat hyperkalemia (high levels of potassium in the blood). Sodium zirconium cyclosilicate is not used for emergency treatment of life-threatening hyperkalemia because it takes some time to work. Sodium zirconium cyclosilicate is in a class of medications called potassium removing agents. It works by removing excess potassium from the body.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Sodium zirconium cyclosilicate comes as a powder in a packet to mix with water and take by mouth with or without food. When starting treatment with sodium zirconium cyclosilicate, it should be taken three times a day for up to 48 hours. After that, it is usually taken once a day or once every other day. Take sodium zirconium cyclosilicate at around the same time every day, or every other day, depending on your response to the medication. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sodium zirconium cyclosilicate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Take any other medications at least 2 hour before or 2 hours after you take sodium zirconium cyclosilicate because sodium zirconium cyclosilicate can interfere with absorption of other medications.

You will need to mix the powder with water right before you take it. To mix the powder, follow these steps:

1. Empty the packet(s) of sodium zirconium cyclosilicate powder into a cup of 3 tablespoons (45 mL) or more of water.
2. Stir and drink immediately.
3. If any powder remains in the cup, add more water, then stir and drink.
4. Repeat as needed until no powder remains to be sure you received the full dose.

Your doctor may increase your dose, but not more than once every 7 days, depending on the results of your laboratory tests.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the packet it came in, sealed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What should I do in case of OVERDOSE?
