Sevelamer hydrochloride, commonly known by its brand name Renagel, helps treat high phosphate levels in the blood (hyperphosphatemia) in adults with chronic kidney disease (CKD) who are receiving dialysis. This medication is a phosphate binder. It attaches to phosphate in food so it's not absorbed into your blood. Sevelamer hydrochloride (Renagel) comes as tablets that are taken by mouth three times per day with meals. Common side effects include nausea, vomiting, and diarrhea. This medication is available as a generic.
High phosphate levels (hyperphosphatemia) in adults with chronic kidney disease (CKD) who are receiving dialysis
Sevelamer hydrochloride (Renagel) is a phosphate binder. It attaches to a nutrient called phosphate in your stomach. The medication prevents phosphate that's in the food you eat from getting absorbed into the body. This lowers the phosphate levels in your blood, which helps prevent additional problems with your kidneys and bones.

Side effects that you should report to your care team as soon as possible:
Side effects that usually do not require medical attention (report to your care team if they continue or are bothersome):
Works well to lower phosphate levels
Taken by mouth
No effect on your calcium levels because it doesn't contain calcium
Not a good choice for people who have trouble swallowing because you can't crush the tablet and there isn't a liquid available
Need to take three times per day with food
Can lower the levels of certain vitamins and minerals in the body
Take sevelamer hydrochloride (Renagel) with each meal of the day. Ask your prescriber if you need to take the medication when you have snacks too.
Make sure to swallow the sevelamer hydrochloride (Renagel) tablet whole. Contact your prescriber if you're having trouble swallowing the tablets so they can switch you to another medication that might be easier for you to take.
Talk with your healthcare team about following a meal plan that helps you avoid foods that are high in phosphorous. This will help keep your phosphate levels low and your kidneys as healthy as possible.
It's common to have side effects like nausea, vomiting, diarrhea, and indigestion with sevelamer hydrochloride (Renagel). You can try treatment options like over-the-counter bismuth subsalicylate (Pepto-Bismol) to help if your healthcare professional says it's safe for you to. Talk with your care team if these side effects are too bothersome and if they don't get better with over-the-counter treatments.
Mark your calendar with your appointments to see your prescriber and to get any blood tests done during your treatment with sevelamer hydrochloride (Renagel). These blood tests measure your electrolyte levels, including your phosphate levels. This helps your prescriber keep track of your kidney health, see how well the medication is working, and make sure it's safe for you to take.
Tell your care team about all of the medications you're taking or planning to take with sevelamer hydrochloride (Renagel). They can help make sure your medications are safe to take together. Your care team can let you know if you need to separate when you take your medications to make sure they don't interfere with each other.
Sevelamer hydrochloride (Renagel) is typically safe to take while pregnant and breastfeeding. But the medication can lower how much certain nutrients get absorbed into the body. Let your obstetrician-gynecologist (OB-GYN) know that you're prescribed sevelamer hydrochloride (Renagel). They might recommend taking a supplement to keep your levels of these vitamins high, even if you're already taking a prenatal vitamin.
Sevelamer hydrochloride (Renagel) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: History of swallowing problems | History of changes to the anatomy of your digestive tract | History of digestive tract problems, including severe constipation | Taking medications that can also cause blockage in the digestive tract
Some people who take sevelamer hydrochloride (Renagel) have had digestive tract problems. These problems can include stomach or intestinal blockage, bleeding ulcers, and inflammation. Some people might also have trouble swallowing.
Ask your prescriber if sevelamer hydrochloride (Renagel) is right for you if you have constipation or other digestive tract problems. Let your care team know right away if you have severe stomach pain, new or worsening constipation, blood in your stool, vomit that looks like coffee grounds, or other severe intestinal (gut) symptoms while you're taking this medication. These can be signs of serious digestive tract problems.
Based on animal studies, sevelamer hydrochloride (Renagel) might lower how well your body can absorb certain vitamins (D, E, and K) and folic acid. Your prescriber might recommend that you take supplements to keep your vitamin levels healthy.
The typical starting dose is 800 mg to 1,600 mg by mouth three times per day with meals. Your prescriber will decide what your starting dose is based on whether you were previously taking a different phosphate binder and what your phosphate levels are.
As you continue treatment, your prescriber might adjust your dose depending on your phosphate levels and any bothersome side effects you have.
