Renvela® Tablets for Hyperphosphatemia

Renvela is a prescription phosphate binder used to control high blood phosphorus in people with chronic kidney disease on dialysis. It works in the gut and is not absorbed. This page explains how it is used, who it is for, and how to store it.

What Renvela Is and How It Works

Renvela® contains sevelamer carbonate, a non-absorbed polymer that binds dietary phosphate in the intestines. Bound phosphate is eliminated in stool, which helps lower serum phosphorus. The treatment does not contain calcium or aluminum. It may also reduce LDL cholesterol by binding bile acids.

CanadianInsulin.com is a prescription referral platform. We verify prescriptions with your prescriber when required, and licensed Canadian pharmacies dispense your order.

Ships from Canada to US is available for eligible orders. You can check the renvela price without insurance on this page before you proceed. After that, compare quantities based on your prescription and care plan.

Who It’s For

This medicine is used to control serum phosphorus in people with chronic kidney disease on dialysis, including adults and certain pediatric patients when prescribed. It may be selected if calcium-based binders are not appropriate.

Do not use it if you have bowel obstruction. Tell your clinician if you have swallowing problems, severe gastrointestinal motility disorders, or recent major gastrointestinal surgery. Review your full medication list to assess interaction risks and timing needs.

Dosage and Usage

Use this medicine exactly as prescribed. Typical therapy is taken three times daily with meals. Your prescriber may adjust the dose based on your lab results and diet.

Swallow tablets whole. Do not crush, chew, or break them. For the powder for oral suspension, open the packet and mix with the instructed amount of water. Stir well and drink the entire mixture within the recommended time. Rinse the cup with a small amount of water and drink to get the full dose.

Take it with food. Skipping doses with meals can reduce control of serum phosphorus. If you start or stop phosphate-containing foods or supplements, your dose may need reassessment. Follow your care team’s instructions and the approved product label for timing and titration.

Strengths and Forms

Common presentations include:

• Tablets: 800 mg
• Powder for oral suspension: single-use packets (for example, 0.8 g and 2.4 g packet strengths)

Availability may vary by pharmacy and manufacturer supply. Your prescription will specify the form and packet count or tablet quantity.

Missed Dose and Timing

If you miss a dose with a meal, take it with your next meal. Do not take extra doses to make up for the missed one. This binder is intended to work with food intake, so consistency with meals matters.

Storage and Travel Basics

Store tablets and packets at room temperature and keep them dry. Protect from moisture. Keep the bottle or packets closed when not in use. As with all medicines, store out of sight and reach of children and pets.

When traveling, keep your medication in its original labeled container. Pack a copy of your prescription. Carry a small buffer supply in your carry-on. Do not mix packets or tablets in unlabeled organizers if you need to show them during security screening. If your regimen changes, follow your prescriber’s new directions and dispose of old packets per local guidance.

Benefits

This phosphate binder lowers phosphorus without adding calcium or aluminum. That can be useful if you need to limit calcium load. The oral powder option offers flexibility for those who have difficulty swallowing tablets. Taking it with meals aligns with routine dialysis diet planning.

Side Effects and Safety

• Digestive upset: nausea or vomiting
• Bowel habit changes: diarrhea or constipation
• Stomach discomfort: abdominal pain or bloating
• Indigestion: gas or fullness

Serious but less common risks include bowel obstruction, ileus, gastrointestinal perforation, and severe constipation. People with swallowing problems can be at risk for choking or esophageal obstruction with large tablets. Metabolic acidosis and vitamin deficiency may occur in dialysis populations; your care team may monitor labs and recommend supplements. Seek urgent care for severe abdominal pain, persistent vomiting, inability to pass stool, or signs of obstruction.

Drug Interactions and Cautions

This binder can reduce absorption of some oral medicines. Your prescriber may advise you to separate dosing. Certain drugs, such as ciprofloxacin, levothyroxine, and mycophenolate derivatives, require particular timing and monitoring. In transplant patients, immunosuppressant levels may need checks if a binder is added. Discuss your full list, including over-the-counter vitamins and iron.

People on transplant immunosuppression should monitor troughs when taking agents like Tacrolimus. For fluid management in CKD, clinicians may use diuretics such as Furosemide Injection, which treat edema but do not control phosphate. If you take thyroid hormone, your clinician may separate doses and check labs. Always follow your prescriber’s advice and the official label.

What to Expect Over Time

Phosphate binding occurs in the gut with each meal. Your clinician may check labs at regular intervals and adjust your dose to help maintain target phosphorus levels. Many digestive side effects are mild and improve with time or with administration adjustments.

Adherence to timing with food and diet counseling helps the binder work as intended. Keep a simple log of doses taken with meals and note any persistent side effects. Bring the log to clinic visits to support dose discussions.

Compare With Alternatives

Phosphate binders differ by active ingredient and mineral content. Calcium acetate adds calcium, which may not suit everyone. Lanthanum carbonate and ferric citrate are other options sometimes used when dietary measures and first choices are not sufficient. Your prescriber will choose an agent based on labs, tolerance, pill burden, and overall kidney care.

Pricing and Access

Canadian pricing with US shipping from Canada can offer value for eligible prescriptions. You can review sevelamer carbonate price ranges on our product page and compare form options. Some patients also ask about renvela cost; final amounts depend on form, quantity, and dispensing pharmacy.

Availability and Substitutions

Supply may vary by form or pack size. If an item is unavailable, your prescriber may recommend a therapeutic alternative in the same class. You can explore related care in our Nephrology section and read about comorbidities such as Diabetic Kidney Disease. If you prefer to order from home, renvela online requests require a valid prescription.

Patient Suitability and Cost-Saving Tips

This treatment may suit people on dialysis who need non-calcium phosphate control and who can take doses with meals consistently. It may not suit those with bowel obstruction, severe gastrointestinal motility issues, or swallowing difficulties with large tablets.

To reduce refill frequency, ask your prescriber if multi-month dispensing is appropriate. Set reminders on your phone or calendar so you do not miss doses. You can also buy renvela in quantities that align with routine lab follow-ups to minimize mid-cycle changes. For patients with diabetes and CKD, medicines like Januvia may be part of broader care; discuss all therapies at visits. For heart-kidney care, your team may consider agents such as Carvedilol when indicated.

Diet counseling is essential with phosphate binders. Our article on Calcium and Diabetes explains how minerals and diet intersect with chronic disease. Another overview on Kerendia Kidney Health discusses cardio-renal medications sometimes used alongside dialysis care.

Questions to Ask Your Clinician

• Starting dose and meal timing: how should I begin?
• Form selection: tablets or powder for my needs?
• Titration plan: how often will labs guide changes?
• Interaction timing: how should I separate other pills?
• Side-effect management: when should I call the clinic?
• Dietary goals: what are my phosphorus targets?
• Long-term plan: how does this fit with my dialysis care?
