Renagel (sevelamer hydrochloride) is a polymeric amine that binds phosphate; it is available in generic form. Renagel is indicated for the control of serum phosphorus in patients with chronic kidney disease on dialysis. The safety and efficacy of Renagel in CKD patients who are not on dialysis have not been studied. Some side effects include but are not limited to severe stomach pain, constipation, fever, chills, body aches, or flu symptoms.
Renagel is available in 400 and 800mg tablets. The recommended starting dose of Renagel is 800 to 1600mg in patients with chronic kidney disease on dialysis. Renegel decreases ciprofloxacin by about 50% but had no effect on Lanoxin (digoxin), Coumadin (warfarin), Vasotec (enalapril), Lopressor, Toprol XL (metoprolol), and iron. The effect of Renagel on the absorption of vitamins and other nutrients has not been studied in pregnant women. The effect of Renagel on labor and delivery in humans are not known. The safety and effectiveness of Renagel in the pediatric population has not been established.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug can not be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In a parallel design study of sevelamer hydrochloride with treatment duration of 52 weeks, adverse reactions reported for sevelamer hydrochloride (n=99) were similar to those reported for the active-control group (n=101). Overall adverse reactions among those treated with sevelamer hydrochloride occurring in > 5% of patients included: vomiting (22%), nausea (20%), diarrhea (19%), dyspepsia (16%), abdominal pain (9%), flatulence (8%) and constipation (8%). A total of 27 patients treated with sevelamer and 10 patients treated with comparator withdrew from the study due to adverse reactions.
In one hundred and forty-three peritoneal dialysis patients studied for 12 weeks most adverse reactions were similar to adverse reactions observed in hemodialysis patients. The most frequently occurring treatment emergent serious adverse reaction was peritonitis (8 reactions in 8 patients [8%] in the sevelamer group and 2 reactions in 2 patients [4%] on active-control). Thirteen patients (14%) in the sevelamer group and 9 patients (20%) in the active-control group discontinued, mostly for gastrointestinal adverse reactions. Patients on peritoneal dialysis should be closely monitored to ensure the reliable use of appropriate aseptic technique with the prompt recognition and management of any signs and symptoms associated with peritonitis.
The following adverse reactions have been identified during post-approval use of sevelamer hydrochloride (Renagel®): pruritus, rash, abdominal pain, fecal impaction and uncommon cases of ileus, intestinal obstruction, and intestinal perforation. Appropriate medical management should be given to patients who develop constipation or have worsening of existing constipation to avoid severe complications.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.
