If you're searching for a lanthanum carbonate coupon, here's what to know first: lanthanum carbonate is a phosphate binder used by people on dialysis, a generic version is available alongside the brand Fosrenol, and cash prices for phosphate binders can vary widely from one pharmacy to the next. Rx.com compares pricing across more than 60,000 U.S. pharmacies so you can see which one has your lanthanum carbonate prescription for less — enter your ZIP above to see today's price near you.
What Is Lanthanum Carbonate?
Lanthanum carbonate (brand name Fosrenol) is a non-calcium, non-aluminum-based phosphate binder. It's FDA-approved to reduce elevated blood phosphate levels (hyperphosphatemia) in people with end-stage renal disease (ESRD) who are on dialysis. It is not established or approved for people with chronic kidney disease who are not yet on dialysis.
Lanthanum carbonate comes as chewable tablets or as an oral powder that can be sprinkled on soft food, and it's taken with or immediately after meals. The tablets must be chewed completely — not swallowed whole — for the phosphate-binding effect to work as intended.
Lanthanum Carbonate Cost and Coupons
A generic version of lanthanum carbonate is available, but that doesn't mean the price is the same everywhere. Cash prices for phosphate binders can differ significantly from pharmacy to pharmacy, so it's worth comparing before you fill. Rx.com checks pricing across a large network of pharmacies nationwide — enter your ZIP code above to see today's price at pharmacies near you and find the lowest option for your prescription.
Because lanthanum carbonate is generic, ask your pharmacist whether the tablet or the oral powder form is stocked and priced better at your preferred pharmacy, since availability and pricing can differ by formulation.
Other Phosphate Binders to Discuss With Your Doctor
Lanthanum carbonate is one of several phosphate binders nephrologists prescribe for dialysis patients with hyperphosphatemia. Others your care team may consider include sevelamer, calcium acetate, ferric citrate, and sucroferric oxyhydroxide. Each binder works a little differently and has its own dosing schedule, pill burden, and tolerability profile, so switching between them should only be done under your nephrologist's guidance.
Lanthanum Carbonate Safety Information
Lanthanum carbonate does not carry an FDA boxed warning. It should not be used by people with a bowel obstruction, ileus, fecal impaction, or acute GI obstruction or perforation. The most commonly reported side effects are gastrointestinal — nausea, vomiting, diarrhea, and abdominal pain. Because lanthanum is minimally absorbed into the bloodstream, systemic toxicity is rare, but caution is still advised for anyone with underlying bowel disease.
Lanthanum carbonate can reduce the absorption of some other oral medications taken at the same time, including certain antibiotics such as tetracyclines and fluoroquinolones — your pharmacist can advise on spacing out doses. Remember to chew tablets completely rather than swallowing them whole. This is general information, not medical advice; talk with your doctor or pharmacist about how lanthanum carbonate fits your specific treatment plan.
