What is Rayaldee?

Rayaldee is an oral medicine prescribed to treat adults with secondary hyperparathyroidism (SHPT), stage 3 or 4 chronic kidney disease (CKD), and low vitamin D levels.

Rayaldee is not for children. Rayaldee is not for people who have stage 5 CKD or are on dialysis.

How Rayaldee works

The active ingredient in Rayaldee is calcifediol. Due to its extended-release formulation, Rayaldee provides steady release of calcifediol over a 12-hour period. Your body converts calcifediol into calcitriol, the active form of vitamin D3.

Calcitriol binds to vitamin D receptors. It activates pathways that cause your body to

  • Absorb more calcium and phosphorus
  • Make less parathyroid hormone (PTH)

Within the first 2 weeks of treatment with Rayaldee in clinical studies, blood levels of calcitriol were increased and of PTH were reduced.

Treatment with Rayaldee

Before you start treatment with Rayaldee, your healthcare provider will check the levels of certain hormones and minerals in your blood. After you have taken Rayaldee for a few months, your healthcare provider will again check these levels.

Hormones and minerals checked may include:

  •  Vitamin D
  •  Parathyroid hormone (PTH)
  •  Calcium
  •  Phosphorus
Be sure to get your lab work as prescribed. Your healthcare provider may adjust the dose of Rayaldee based on the results.

In clinical trials, Rayaldee has been very well tolerated.

Health issues that occur during a clinical trial are called treatment-emergent adverse events (TEAEs). In clinical trials of Rayaldee, some people received Rayaldee and others received placebo (“sugar” pill). Among people taking Rayaldee, only about 5% (5 out of 100) had to stop treatment because of a TEAE. A similar number of people taking placebo, about 4% (4 out of 100), had to stop because of a TEAE.

These are the most common side effects of Rayaldee:

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

Constipation

Talk with your healthcare provider.

Be sure to let your healthcare provider know how you feel or if you have any issues. There may be ways for them to help.

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 medications 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.
  1. If you have questions regarding why you were prescribed Rayaldee, please speak with your doctor.
  2. If you have questions regarding the support programs offered by OPKO Connect, you can call 1-844-414-OPKO (1-844-414-6756), option 1.
