Frequently Asked Questions About Rayaldee® (calcifediol) extended-release capsules and SHPT

Secondary hyperparathyroidism (SHPT) can develop as a complication of chronic kidney disease (CKD). 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. SHPT occurs when the parathyroid makes too much parathyroid hormone (PTH).

Left untreated, SHPT can cause health issues such as osteoporosis, bone fractures, kidney stones, heart disease, and high blood pressure. Rayaldee has not been proven to completely get rid of vitamin D insufficiency nor control SHPT.

Rayaldee is a prescription oral medicine that is indicated for treating adults with secondary hyperparathyroidism with stage 3 or 4 chronic kidney disease and low vitamin D levels. Rayaldee helps to increase the vitamin D levels and lower the parathyroid hormone levels found in the blood.

Your healthcare provider will keep track of how how your body responds to treatment with Rayaldee by monitoring levels of vitamin D, parathyroid hormone, calcium, and phosphorus. Your dose of Rayaldee may be adjusted based on these results.

In clinical trials, Rayaldee has been very well tolerated. In the group of people who were taking Rayaldee, only about 5 out of 100 people needed to stop their treatment because of treatment-emergent events. Of the people who were taking a placebo ("sugar" pill), 4 out of 100 people needed to stop their treatment because of treatment-emergent events.

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, increased levels of blood creatinine (a measure of kidney function), shortness of breath, cough, congestive heart failure, and constipation.

Calcium levels that are too high, also known as hypercalcemia, may occur during treatment with Rayaldee. Six people in the clinical trial needed to have their dose of Rayaldee adjusted because of increases in calcium. About 4 in 100 people in the clinical trial who were taking Rayaldee in the clinical trial had at least one elevation in calcium above normal limits, and none of those were found to be clinically significant. About 2 people in 100 who were taking the placebo ("sugar" pill) in the clinical trial experienced a similar elevation in calcium.

People who have secondary hyperparathyroidism (SHPT) have high levels of parathyroid hormone (PTH) and often also have low levels of vitamin D. Over-the-counter vitamin D addresses only the low levels of vitamin D and not the high PTH. Additionally, Over-the-counter vitamin D has not been FDA-approved to treat of SHPT.

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.
