How does this medication work?
Sevelamer, Renvela/Renagel binds phosphate within the intestinal tract, limiting absorption and decreasing serum phosphate concentrations without altering calcium, aluminum, or bicarbonate concentrations.
How should I take this medication?
Control of serum phosphorous: Oral: 800 to 1,600 mg 3 times daily with meals; the initial dose may be based on serum phosphorous levels; maximum dose studied was equivalent to 13 g/day sevelamer hydrochloride or 14 g/day sevelamer carbonate.
Note: The dosing of sevelamer carbonate and sevelamer hydrochloride are similar; when switching from one product to another, the same dose (on a mg per mg basis) should be utilized.
