What is Renagel?
Renagel (sevelamer hydrochloride) is a phosphate binder used to control phosphorus levels in people with chronic kidney disease (CKD) on dialysis. High phosphorus levels in these patients can lead to serious health problems like bone disease and heart complications. The drug works by binding with dietary phosphate in the digestive tract, preventing it from being absorbed into the bloodstream. This helps maintain healthier phosphorus levels, protecting patients from long-term complications. Many patients choose this medication due to its effectiveness and because it does not contain calcium, which helps prevent an excess calcium buildup in the body.
This medication is available in tablet form, typically taken with meals to maximize its phosphate-binding effect. Its unique formulation is particularly beneficial for patients managing CKD, as it minimizes phosphate absorption without adding additional elements that may interfere with other medications or cause calcium imbalances. Clinical studies have shown that Renagel effectively lowers serum phosphorus, making it a preferred choice for kidney patients worldwide. For best results, the CKD phosphorus treatment should be used alongside a doctor-recommended diet and routine monitoring of blood phosphorus levels.

FAQ
What is Renagel used to treat?
Renagel (sevelamer hydrochloride) is primarily used to manage high phosphorus levels in patients with chronic kidney disease (CKD) who are on dialysis. Excess phosphorus in the blood can lead to serious complications such as bone disease and cardiovascular issues, both common concerns in individuals with CKD. It works by binding to phosphate in the digestive tract, preventing it from being absorbed into the bloodstream. This process helps maintain a healthier balance of minerals in the body, reducing the risks associated with high phosphorus. It is especially beneficial for dialysis patients, as their kidneys cannot remove phosphorus efficiently. By keeping phosphorus levels controlled, the drug contributes to improved bone and heart health. This medication is often recommended as part of a comprehensive treatment plan, including a low-phosphorus diet and regular monitoring of blood levels.
Do you take Renagel with food?
Yes, the tablet should be taken with food to maximize its effectiveness. The medication works by binding to phosphate in the digestive system, so it’s essential to take it with meals when phosphorus from food is actively being absorbed. This timing helps sevelamer bind with dietary phosphate and prevent it from entering the bloodstream. Without food, the medication’s binding action may be significantly less effective. Most patients are advised to take the medication at the beginning of a meal or immediately before eating. Following your healthcare provider’s instructions on timing and dosage is crucial for achieving the best results in controlling phosphorus levels. For specific dosing recommendations, always consult your doctor or pharmacist.
What is the difference between Renvela and Renagel?
Renvela and Renagel are both phosphate binders used to manage high phosphorus levels in patients with CKD on dialysis, but they have some notable differences. Below is a comparison to help illustrate their key distinctions:
| Feature | Renagel (Sevelamer Hydrochloride) | Renvela (Sevelamer Carbonate) |
|---|---|---|
| Formulation | Sevelamer hydrochloride | Sevelamer carbonate |
| Effect on Bicarbonate Levels | No effect on bicarbonate levels | Helps maintain bicarbonate levels, useful for acid-base balance |
| Common Side Effects | Gastrointestinal issues may be more common | May have fewer GI side effects due to carbonate formulation |
| Dosage Form | Tablet | Tablet and powder form available |
| Preference for Certain Conditions | Sometimes chosen when carbonate is unsuitable | Often preferred due to added acid-base support |
| Administration | Take with meals | Take with meals |

Renagel can interact with certain medications, impacting their effectiveness. To ensure safe use, it’s essential to manage the timing of sevelamer hydrochloride with other drugs, especially those sensitive to absorption. Here are some common interactions:
- Antibiotics: Medications like ciprofloxacin should be taken at least one hour before or three hours after Renagel to avoid reduced absorption.
- Immunosuppressants: Mycophenolate mofetil may interact with this phosphate-reducing medication, so spacing out doses is recommended.
- Heart Medications: Some heart medications, including beta-blockers and antiarrhythmics, may be affected. Consult your doctor for specific timing guidance.
- Anti-seizure Medications: Phenytoin and other seizure drugs may have altered absorption when taken with sevelamer tablets.
To minimize interactions, always inform your healthcare provider of all medications and supplements you take. In many cases, adjusting the timing of doses can help maintain the effectiveness of all medications involved.
Is there a generic version of Renagel?
Yes, a generic version of Renagel, called sevelamer hydrochloride, is available.
