What is Zemplar?
Zemplar is a prescription medication containing paricalcitol, a synthetic form of active vitamin D. Zemplar is primarily used to treat and prevent a condition called secondary hyperparathyroidism. This condition occurs in patients who have chronic kidney disease. The kidneys are unable to produce enough active vitamin D. This leads to an imbalance of hormones. Eventually, this can cause serious bone and mineral problems if left untreated. Zemplar helps restore balance and protect your bones.
How does Zemplar work?
Zemplar works by directly targeting the parathyroid glands in your neck. These glands control the level of parathyroid hormone (PTH) in your blood. In chronic kidney disease, these glands become overactive and produce too much PTH. Zemplar signals these glands to reduce their hormone production. This action helps to lower PTH levels. As a result, it helps manage calcium and phosphorus levels in the body. This prevents the bones from losing calcium and becoming weak.
Who is Zemplar for?
Zemplar is intended for adults and children aged 10 and older with chronic kidney disease. Specifically, it is for patients in later stages (3, 4, and 5) who have developed secondary hyperparathyroidism. This includes patients who are on dialysis. A doctor will confirm the diagnosis through blood tests that measure PTH, calcium, and phosphorus levels. You should only use Zemplar under the supervision of a healthcare provider who can monitor your condition and response to the treatment.
Dosage and administration
Zemplar dosage is carefully calculated by your doctor based on your body weight and PTH levels. It is available as an oral capsule. You can take the capsule with or without food. The pill should be swallowed whole with a glass of water. Do not crush, chew, or open the capsule. Your doctor will tell you how often to take it, which could be daily or a few times a week. It is critical to follow the prescribed dosage instructions exactly to ensure the medication works safely and effectively.
Side effects
Zemplar may cause side effects, though not everyone experiences them. The most common side effects are related to changes in calcium levels. These include nausea, vomiting, dry mouth, and constipation. Some people might also experience chills, fever, or flu-like symptoms. More serious side effects can occur if your blood calcium levels get too high. Symptoms include confusion, weakness, irregular heartbeat, or appetite loss. Contact your doctor immediately if you experience severe symptoms or signs of an allergic reaction.

Serious Side Effects
You should contact your doctor right away if you experience any serious side effects. An overdose can cause high blood calcium (hypercalcemia). Signs of this include confusion, severe constipation, or muscle weakness. Other serious effects can include:
- Fast, irregular, or pounding heartbeats
- Chest fluttering or shortness of breath
- Sudden vision changes or eye pain
- Severe allergic reactions like rash, hives, or swelling
- Signs of gastrointestinal bleeding
Zemplar is indicated for the treatment and prevention of high levels of parathyroid hormone (secondary hyperparathyroidism) in patients with chronic kidney disease.
This condition occurs when the kidneys fail to produce enough active vitamin D, leading to hormone imbalances. If untreated, it can cause symptoms like:
- Nausea and vomiting
- Drowsiness and confusion
- Muscle spasms
- Bone and joint pain
- Irregular heartbeats
Untreated hyperparathyroidism can also lead to significant bone abnormalities and an increased risk of fractures.
