Injection: Multidose prefilled delivery device (pen) with 28 daily doses of 20 mcg/dose (600 mcg/2.4 ml)
Indications and dosages
➣ Osteoporosis in patients at high risk for bone fracture
Adults: 20 mcg/day subcutaneously for up to 2 years
• Hypersensitivity to drug
• Conditions that increase osteosarcoma risk (such as Paget's disease, unexplained alkaline phosphatase elevation, open epiphyses, skeletal radiation therapy)
• Bone cancer metastases or history of bone cancer
• Metabolic bone disease other than osteoporosis
Use cautiously in:
• urolithiasis, hypotension
• concurrent use of cardiac glycosides
• pregnant or breastfeeding patients.
• Inject subcutaneously into thigh or abdominal wall, with patient lying down.
• Know that prefilled injection pen delivers 20 mcg of drug per actuation and may be reused for up to 28 days after first injection. Discard pen in protected container after 28 days, even if it's not empty.

Drug-diagnostic tests. Calcium: increased level
• Monitor respiratory and neurologic status and assess patient's mood.
• Monitor bone mineral density tests and calcium level.
• Instruct patient to promptly report such adverse reactions as cough and difficulty breathing.
• Tell patient that prefilled injection pen delivers 20 mcg of drug per actuation. Inform him that he may reuse it for up to 28 days after first injection, and should then discard it in appropriate receptacle, even if it's not empty.
• Advise patient to establish effective bedtime routine to minimize insomnia.
