What is Veltassa?
Veltassa (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).
Veltassa is used to treat hyperkalemia (high levels of potassium in your blood).
Veltassa works differently from other medicines because it passes through your stomach and into your intestines without being absorbed into your blood stream.
Avoid use of Veltassa if you have severe constipation, bowel obstruction or impaction. Veltassa may be not work effectively and may worsen your condition.
Veltassa also binds to magnesium in your digestive tract which can lead to low levels of magnesium in the body.
Avoid taking other medicines by mouth within 3 hours before or 3 hours after you take patiromer.
