Causes of SHPT

People with chronic kidney disease (CKD) are at risk for developing secondary hyperparathyroidism (SHPT). In fact, of the people who have stage 3 CKD, 2 out of 5 develop SHPT. And of the people who have stage 4 CKD, 4 out of 5 develop SHPT.

When someone has a diagnosis of SHPT, stage 3 or 4 CKD, and low vitamin D levels, effective treatment for SHPT may help. Left untreated, SHPT can get worse and become more difficult to treat. Without treatment, SHPT can cause issues such as

  • High blood pressure
  • Heart disease
  • Kidney stones
  • Osteoporosis
  • Bone fractures

Rayaldee (calcifediol) extended-release tablets has not been proven to completely get rid of vitamin D insufficiency nor control secondary hyperparathyroidism.

Important Safety Information

Before starting Rayaldee, the level of calcium in your blood should be in the normal range (below 9.8 mg/dL). Your doctor can tell you if your calcium level is right for starting Rayaldee.

Rayaldee can cause hypercalcemia and hypercalciuria (high levels of calcium in your blood and urine, respectively). You should tell your doctor if you are taking any other medications, including other vitamin D medications (prescription or over-the-counter vitamin D supplements). Your doctor may tell you to stop taking them while you are taking Rayaldee, as very high calcium levels due to high vitamin D levels could cause severe changes to your heart rhythm or seizures and require emergency treatment.

Tell your doctor about any and all medication you may be taking. While you are taking Rayaldee, tell your doctor if you receive any new prescriptions or start any new over-the-counter medications.

Tell your doctor immediately if you experience any of the following symptoms of very high calcium: feeling tired, difficulty thinking clearly, loss of appetite, nausea, vomiting, constipation, increased thirst, increased urination, weight loss, or any other abnormal symptoms or side effects.

While you are taking Rayaldee, your doctor will order laboratory tests to see how your SHPT is doing. These lab tests will also examine your blood levels of calcium, phosphorus, 25-hydroxyvitamin D, and PTH. Based on your test results, your dose of Rayaldee may be changed or stopped until your lab results improve.

The most common side effects of Rayaldee reported by patients in clinical trials were anemia (low levels of red blood cells or hemoglobin), infection in the nose and/or throat, high levels of blood creatinine (a lab test for measuring kidney function), shortness of breath, cough, congestive heart failure, and constipation. 

Take your Rayaldee at bedtime and swallow your capsules whole; do not bite or chew them.

If you miss a dose, take Rayaldee at your next scheduled time. Do not take an extra dose to make up for the dose you missed.

Be sure to follow your doctor’s orders, including getting your laboratory tests done on time.
