Italics	For the most part, italics indicate an FDA comment such as: Additions and/or revisions underlined These italics usually appear at the beginning of the section. In some cases, italics may be an inherent part of the label, and will most often appear in the body of the section.
Underlines	Any text that is underlined indicates text that has been added or revised. There are exceptions where underlining occurs in a section subtitle or heading. This is the case when there is just one word underlined in the body of the text.

PCI/PI/MG	Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events.

Only NDAs and CDER regulated BLAs are included in this database. ANDAs are not included.

Applications that remain active, even if the product has been discontinued, undergo safety-related labeling changes.

4 Contraindications

(Additions and/or revisions underlined)

Paricalcitol Injection is contraindicated in patients with:

Known hypersensitivity to paricalcitol or any inactive ingredient in Paricalcitol Injection. Hypersensitivity adverse reactions have been reported [e.g., angioedema (including laryngeal edema) and urticaria].

5 Warnings and Precautions

5.1 Hypercalcemia

(Additions and/or revisions underlined)

Hypercalcemia may occur during Paricalcitol Injection treatment. Acute hypercalcemia may increase the risk of cardiac arrhythmias and seizures and may potentiate the effect of digitalis on the hear. Chronic hypercalcemia can lead to generalized vascular calcification and other soft-tissue calcification. Severe hypercalcemia may require emergency attention.

Hypercalcemia may be exacerbated by concomitant administration of high doses of calcium-containing preparations, thiazide diuretics, or other vitamin D compounds. In addition, high intake of calcium and phosphate concomitantly with vitamin D compounds may lead to hypercalciuria and hyperphosphatemia. Patients with a history of hypercalcemia prior to initiating therapy may be at increased risk for development of hypercalcemia with Paricalcitol Injection. In these circumstances, frequent serum calcium monitoring and Paricalcitol Injection dose adjustments may be required.

When initiating Paricalcitol Injection or adjusting Paricalcitol Injection dose, measure serum calcium frequently (e.g., twice weekly). Once a maintenance dose has been established, measure serum calcium at least monthly. If hypercalcemia occurs, reduce the dose or discontinue Paricalcitol Injection until serum calcium is normal.

Inform patients about the symptoms of elevated calcium (feeling tired, difficulty thinking clearly, loss of appetite, nausea, vomiting, constipation, increased thirst, increased urination and weight loss) and instruct them to report new or worsening symptoms when they occur.

5.2 Digitalis Toxicity

(Additions and/or revisions underlined)

HParicalcitol Injection can cause hypercalcemia which increases the risk of digitalis toxicity. In patients using Paricalcitol Injection concomitantly with digitalis compounds, monitor serum calcium and patients for signs and symptoms of digitalis toxicity. Increase the frequency of monitoring when initiating or adjusting the dose of Paricalcitol Injection.

5.3 Adynamic Bone Disease

(Additions and/or revisions underlined)

Adynamic bone disease with subsequent increased risk of fractures may develop if intact PTH levels are suppressed by Paricalcitol Injection to abnormally low levels. Monitor intact PTH levels to avoid over suppression and adjust Paricalcitol Injection dose, if needed.

6 Adverse Reactions

(Additions and/or revisions underlined)

The following serious adverse reactions are described below and elsewhere in the labeling:

Hypercalcemia
Adynamic Bone Disease

6.1 Clinical Trials Experience

(Extensive changes; please refer to label)

8 Use in Specific Populations

8.1 Pregnancy

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; please refer to label)

8.2 Lactation

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; additions and/or revisions underlined)

Risk Summary

There is no information available on the presence of paricalcitol in human milk, the effects of the drug on the breastfed infant or the effects of the drug on milk production. Studies in rats have shown that paricalcitol and/or its metabolites are present in the milk of lactating rats. When a drug is present in animal milk, it is likely that the drug will be present in human milk. Infants exposed to Paricalcitol Injection through breast milk should be monitored for signs and symptoms of hypercalcemia. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Paricalcitol Injection and any potential adverse effects on the breastfed child from Paricalcitol Injection or from the underlying maternal condition.

Clinical Considerations

Infants exposed to Paricalcitol Injection through breast milk should be monitored for signs and symptoms of hypercalcemia, including seizures, vomiting, constipation, and weight loss. Monitoring of serum calcium in the infant should be considered.

Data

Following a single oral administration of 20 mcg/kg of radioactive [3H] paricalcitol to lactating rats, the concentrations of total radioactivity was determined. Lower levels of total radioactivity were present in the milk compared to that in the plasma of the dams indicating that low levels of [3H] paricalcitol and/or its metabolites are secreted into milk. Exposure of the pups to [3H] paricalcitol through milk was confirmed by the presence of radioactive material in the pups’ stomachs.

8.4 Pediatric Use

(Additions and/or revisions underlined)

The safety and efficacy of Paricalcitol Injection for the prevention and treatment of secondary hyperparathyroidism associated with CKD have been established in pediatric patients 5 years of age and older with CKD on dialysis. Use of Paricalcitol Injection in pediatric patients 5 years of age and older is supported by evidence from an adequate and well-controlled study with another paricalcitol product in 29 patients, 5 to 19 years of age, with CKD on hemodialysis.

The safety and efficacy of Paricalcitol Injection have not been established in pediatric patients less than 5 years old.

8.6 Hepatic Impairment

(Newly added subsection)

The pharmacokinetics of paricalcitol were studied in patients with mild and moderate hepatic impairment and were similar to that of patients with normal hepatic function. No dose adjustment is required in patients with mild or moderate hepatic function.

Paricalcitol Injection has not been studied in patients with severe hepatic impairment.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

17 PATIENT COUNSELING INFORMATION

(Additions and/or revisions underlined)

Hypercalcemia

Advise patients to contact a health care provider if they develop symptoms of elevated calcium (e.g. feeling tired, difficulty thinking clearly, loss of appetite, nausea, vomiting, constipation, increased thirst, increased urination, and weight loss.

Monitoring

Inform patients that they will need routine monitoring of laboratory parameters such as calcium, phosphorus, and intact PTH while receiving Paricalcitol Injection. Inform patients that more frequent monitoring is necessary during the initiation of therapy, following dose changes or when potentially interacting medications are started or discontinued.

Drug Interactions

Advise patients to inform their physician of all medications, including prescription and nonprescription drugs, and supplements they are taking. Advise patients to also inform their physician that they are receiving Paricalcitol Injection if a new medication is prescribed.

Diet

Advise patients to adhere to instructions regarding diet and phosphorus restriction.
