Effectiveness

How Zemplar Affects PatientsSecondary hyperparathyroidism is caused by a lack of vitamin D in the body, which is usually made naturally in the skin and obtained from diet. Vitamin D needs to go through two processes in the liver and kidney to be activated, and this is done by a hormone called calcitriol. Without enough calcitriol, the parathyroid gland, intestine, kidney, and bone cannot keep calcium and phosphorus in balance. This causes secondary hyperparathyroidism, which affects bone turnover and can cause renal osteodystrophy. Paricalcitol is a medication used to treat secondary hyperparathyroidism and it has been

How Zemplar works in the bodyParicalcitol is a synthetic form of vitamin D. It works by binding to a protein in the body, called the Vitamin D Receptor (VDR). This causes other proteins in the body to work differently, including reducing the amount of Parathyroid Hormone (PTH) in the body. PTH normally increases the amount of calcium in the blood, which can be harmful if it gets too high.

Zemplar for Hyperparathyroidism caused by Chronic Kidney Failure

My PTH level dropped from 245 to 65 after using this treatment, which is amazing.

Zemplar for Hyperparathyroidism caused by Chronic Kidney Failure

This medication has done wonders for me. I previously had trouble with Vitamin D deficiency and renal issues. Because of the Vitamin D not absorbing, Zemplar has helped that process.

Zemplar for Hyperparathyroidism caused by Chronic Kidney Failure

I've been using this treatment for over six months and my levels are now normal. It can be tough to find a vitamin supplement without vitamin D, so if you have suggestions please let me know!

Zemplar for Hyperparathyroidism caused by Chronic Kidney Failure

I feel like this medication is making me more fuzzy-headed, giving me diarrhea, and increasing my depression.

Zemplar for Hyperparathyroidism caused by Chronic Kidney Failure

I've been taking this medication for over a year now and I haven't seen any changes in my blood tests. Not sure if it's working or not, but it is expensive either way.
