What is Fosrenol
Lanthanum carbonateThe Generic name of this drug
Treatment SummaryLanthanum carbonate, also known as Fosrenol, is a medication used to lower high phosphate levels in people with chronic kidney disease. It is a large pill that should be chewed and taken with meals to help bind to the phosphate in food and stop it from being absorbed by the intestine. Sometimes people forget to chew the pill and have experienced severe choking as a result.

Effectiveness
How Fosrenol Affects PatientsLaboratory tests have shown that lanthanum can effectively bind phosphate at a range of acidity levels found in the human body (pH 3-7). When tested in a simulated stomach environment, lanthanum was able to bind up to 97% of the available phosphate when it was present in double the amount of phosphate. Bile acids do not affect the phosphate binding ability of lanthanum. To work properly, lanthanum must be taken with or right after meals.
How Fosrenol works in the bodyLanthanum carbonate helps to reduce the amount of phosphate absorbed by the body. It does this by forming a complex with the phosphate that cannot be absorbed by the body. This complex then passes through the digestive system, preventing it from entering the bloodstream. As a result, the amount of both phosphate and calcium phosphate in the body is reduced.

Fosrenol Reviews: What are patients saying about Fosrenol?
5Patient Review
5/16/2013 I find that grinding the tablets into a powder makes them much easier to take and improves the taste. I actually enjoy the sweetness of the powder.
5Patient Review
6/21/2012 As a home hemodialysis patient, my phosphorus levels were through the roof. 11.0 to be exact. But after my nutritionist suggested I try Fosrenol (2 500mg chewable tablets with meals and snacks), it lowered my phosphorus all the way down to 3.5; which is well within the normal range of 3.5-5.5. Not only that, but this product tastes like tums! And I have experienced zero stomach problems or nausea from taking it regularly.
5Patient Review
1/17/2009 I'm on dialysis for end stage renal failure, and this product has been great for keeping my phosphorus levels in check. I chew one 1000mg tablet after every meal and snack, and it's really helped me out.
5Patient Review
7/30/2009 I've had a great experience with this medication. It's easy to chew and I stay in range on my report card. Some of the other comments mention having trouble with upset stomach and nausea, but that improved for me within two months.

12/21/2010 I had some initial success with this medication but unfortunately it led to chronic gas, stomach pain, and severe constipation.
2.3Patient Review
8/22/2009 I felt nauseous and had an upset stomach after taking Renvela. Fosrenol is much easier to chew and I didn't experience any dizziness, weakness, or vomiting.
2Patient Review
10/14/2007 I've been taking Fosrenol for a few months now and have experienced worsening nausea and vomiting. I'm wondering if anyone else has had similar issues?
Patient Q&A Section about fosrenol
These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.What type of medication is Fosrenol?
"FOSRENOL works by binding phosphate in the gut so that it isn't absorbed into the body, reducing serum phosphate levels."
Answered by AI
When should I take Fosrenol?
"Fosrenol should be taken with food to avoid nausea and vomiting. The tablets must be chewed completely and not swallowed whole. To aid with chewing, the tablets may be crushed."
Answered by AI
Is there a generic for Fosrenol?
"Lanthanum, the generic version of the drug Fosrenol, may be much cheaper than the brand version of the drug."
Answered by AI
What is Fosrenol used for?
"Fosrenol prevents the body from absorbing phosphate by bind to it in the gastrointestinal tract, which then allows it to be removed from the body through the feces. This medication is used to treat patients with end stage renal disease who have high phosphate levels in their blood, which can lead to problems with calcium absorption and other serious medical problems."
