Miacalcin injection is indicated for the treatment of symptomatic Paget’s disease of bone in patients with moderate to severe disease characterized by polyostotic involvement with elevated serum alkaline phosphatase and urinary hydroxyproline excretion. There is no evidence that the prophylactic use of calcitonin salmon is beneficial in asymptomatic patients. Miacalcin injection should be used only in patients who do not respond to alternative treatments or for whom such treatments are not suitable (e.g., patients for whom other therapies are contraindicated or for patients who are intolerant or unwilling to use other therapies).
Miacalcin injection is indicated for the early treatment of hypercalcemic emergencies, along with other appropriate agents, when a rapid decrease in serum calcium is required, until more specific treatment of the underlying disease can be accomplished. It may also be added to existing therapeutic regimens for hypercalcemia such as intravenous fluids and furosemide, oral phosphate or corticosteroids, or other agents.
Miacalcin injection is indicated for the treatment of postmenopausal osteoporosis in women greater than 5 years postmenopause. The evidence of efficacy for calcitonin salmon injection is based on increases in total body calcium observed in clinical trials. Fracture reduction efficacy has not been demonstrated. Miacalcin injection should be reserved for patients for whom alternative treatments are not suitable (e.g., patients for whom other therapies are contraindicated or for patients who are intolerant or unwilling to use other therapies).
Due to the possible association between malignancy and calcitonin salmon use, the need for continued therapy should be re-evaluated on a periodic basis [see Warnings and Precautions (5.3)].
The recommended dose of Miacalcin injection for treatment of symptomatic Paget’s disease of bone is 100 USP Units (0.5 mL) per day administered subcutaneously or intramuscularly.
The recommended starting dose of Miacalcin injection for early treatment of hypercalcemia is 4 USP Units/kg body weight every 12 hours by subcutaneous or intramuscular injection. If the response to this dose is not satisfactory after one or two days, the dose may be increased to 8 USP Units/kg every 12 hours. If the response remains unsatisfactory after two more days, the dose may be further increased to a maximum of 8 USP Units/kg every 6 hours.
The recommended dose of Miacalcin injection for treatment of postmenopausal osteoporosis in women greater than 5 years postmenopause is 100 USP Units (0.5 mL) per day administered subcutaneously or intramuscularly. The minimum effective dose of Miacalcin injection for the prevention of vertebral bone mineral density loss has not been established.
Visually inspect Miacalcin vials. Miacalcin injection is a clear, colorless, solution. If the solution is not clear and colorless, or contains any particles, or if the vial is damaged, do not administer the solution.
If the volume of Miacalcin injection to be injected exceeds 2 mL, intramuscular injection is preferable and the total dose should be distributed across multiple sites of injection.
Instruct patients to use sterile injection technique when administering Miacalcin injection, and to dispose of needles properly.
Patients who use Miacalcin injection for treatment of postmenopausal osteoporosis should receive adequate calcium (at least 1000 mg elemental calcium per day) and vitamin D (at least 400 International Units per day).
The pharmacologic actions of Miacalcin injection suggest that hypocalcemic tetany could occur in overdose. Therefore, provisions for parenteral administration of calcium should be available for the treatment of overdose.
A dose of calcitonin salmon l000 International Units subcutaneously may produce nausea and vomiting. Doses of 32 International Units per kg per day for 1 to 2 days demonstrate no other adverse effects. Data on chronic high-dose administration are insufficient to assess toxicity.
Store in a refrigerator between 2° to 8°C (36° to 46°F).
