What is patiromer?

Patiromer is a medicine that binds itself to potassium in your digestive tract. This helps prevent your body from absorbing too much potassium. Patiromer also helps your body get rid of excess potassium through your stools (bowel movements).

Patiromer is used to treat hyperkalemia (high levels of potassium in your blood).

Patiromer works differently from other medicines because it passes through your stomach and into your intestines without being absorbed into your blood stream.

Patiromer may also be used for purposes not listed in this medication guide.

Important Information

Avoid taking other medicines by mouth within 3 hours before or 3 hours after you take patiromer.

Before taking this medicine

To make sure patiromer is safe for you, tell your doctor if you have:

Because patiromer is not absorbed into the blood stream, this medicine is not expected to be harmful during pregnancy or while nursing a baby. Tell your doctor if you are pregnant or breast-feeding.

Patiromer is not approved for use by anyone younger than 18 years old.

How should I take patiromer?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Patiromer is usually taken once daily with food.

Patiromer oral powder must be mixed with water before you take it. Stir this mixture well and drink all of it right away. To make sure you get the entire dose, add a little more water to the same glass, swirl gently and drink right away.

Do not mix patiromer oral powder with hot liquid or hot food. Do not take the dry powder without mixing it with water.

While using patiromer, you may need frequent blood tests.

Patiromer may be only part of a treatment program that also includes a special diet. Follow your doctor's instructions very closely.

Store unmixed oral powder in the refrigerator. Do not open a medicine packet until you are ready to mix a dose.

You may also store patiromer at room temperature, away from moisture and heat.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose may cause low potassium (leg cramps, constipation, fluttering in your chest, thirst, urination, numbness or tingling, muscle weakness or limp feeling).

What should I avoid while taking patiromer?

Avoid taking other medicines within 3 hours before or 3 hours after you take patiromer. Patiromer can make it harder for your body to absorb other medicines you take by mouth. This could make the other medicines less effective.
