How VELTASSA works—and keeps working

Arrow pointing right icon

VELTASSA binds to excess potassium in the colon and removes it from your body. VELTASSA is not absorbed by the body.

95% icon

In a 52-week clinical study, up to 95% of adults taking VELTASSA reduced their potassium levels and kept them normal (3.8 to < 5.1 mEq/L) over time.

If you stop taking VELTASSA, even for a few days, your potassium levels can increase.*

After a 2-week dose-finding phase of a clinical study, 50% of pediatric patients had normal potassium levels (3.8 to < 5.0 mEq/L).

*In a clinical study, patients who stopped taking VELTASSA experienced an increase in their potassium levels within 1 week.

If you’re prescribed once daily VELTASSA, it’s important to take it correctly.
