Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Renagel (Sevelamer-hydrochloride).

If you have gastrointestinal disorders (e.g., dysphagia [difficulty swallowing], severe disorders of movement in the gastrointestinal tract [i.e., the esophagus, stomach, and bowel]) or you have had major gastrointestinal surgery, discuss with your doctor how Renagel (Sevelamer-hydrochloride) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Renagel (Sevelamer-hydrochloride), and whether any special monitoring is needed.
