Fosrenol (lanthanum)

Prescription only
Raises Vitamin D levels.

Hectorol (Doxercalciferol) works well for people with low vitamin D in kidney disease, but you'll need regular blood tests and you have to avoid certain antacids.

3.1/ 5 average rating with 37 reviewsforHectorol
Lowers phosphate levels.

Fosrenol (lanthanum) works well to lower blood phosphate levels without affecting blood calcium levels in people with advanced kidney disease, but it can be expensive, and you need to take it with meals.

Upsides
  • Effective for treating overactive parathyroid glands due to kidney disease.
  • Available as a generic.
  • Available as either an oral capsule or an IV solution.
  • It's made from the plant-based version of vitamin D, so it's useful for vegetarians.
  • Works as well as other phosphate binders to lower blood phosphate levels.
  • Easy to take since Fosrenol (lanthanum) comes in powder form, and the tablet form can be crushed or chewed.
  • Is calcium-free, which means Fosrenol (lanthanum) doesn't come with the risk of high calcium levels like some alternative medicines.
Downsides
  • Your doctor will want to take blood tests to make sure that your body is responding to the medication.
  • Your doctor may prescribe other medications to make sure other chemicals (phosphate and calcium) in your body remain in balance.
  • Can interact with antacids that contain magnesium.
  • Like other phosphate binders, Fosrenol (lanthanum) must be taken with meals.
  • Is more expensive than other phosphate binders.
