Once you put the bottle and pump assembly together, you may keep the medicine at room temperature, away from light and heat. Store the bottle upright with the pump attached.
Before your first use of the assembled bottle and pump, you must prime the spray. Allow the medicine to reach room temperature before priming.
To prime calcitonin nasal, press the pump at least 5 times until a fine mist appears. Prime the spray only before your first use of the newly assembled bottle.
To use the nasal spray:
Blow your nose gently. Keep your head upright and insert the tip of bottle into one nostril. Hold the nasal spray upright with your first and second fingers on each side of the pump and your thumb on the bottom of the bottle.
Pump the spray unit firmly to spray the medicine into your nostril. You do not need to sniff or inhale deeply.
Do not blow your nose for at least a few minutes after using the nasal spray.

Calcitonin nasal is usually given as one spray per day into only one of your nostrils. Use the other nostril the next day and continue alternating back and forth for each daily dose.
Calcitonin nasal spray delivers a fine mist into the nose. Even if you do not feel the spray while using it, the medication is still being absorbed by your nasal passages.
Each bottle contains 30 doses of calcitonin nasal. Throw away the medicine after 30 uses, even if there is still medicine left in the bottle.

Calcitonin nasal dosing information
Usual Adult Dose for Paget's Disease:
50 to 100 intl units given subcutaneously or intramuscularly once a day. The dosage may be reduced to 50 to 100 intl units subcutaneously or intramuscularly three times a week when improvement (clinical or biochemical) occurs. Calcitonin is usually not given for more than 6 months unless there are neurological symptoms or extensive lytic lesions in the weight-bearing bones. Biochemical remissions of the illness generally last for under six months. If retreatment is necessary, the same initial and maintenance dosage schedules generally are repeated. Human calcitonin is an orphan drug that may be used in patients that develop resistance or an allergic reaction to calcitionin-salmon.
200 to 400 intl units by intranasal administration once a day may also be used with a slight loss in efficacy (400 intl units nasal dose compared to 100 intl units intramuscular dose) but a decrease in systemic side effects. Studies have demonstrated that intranasal preparations reduced bone turnover by 30% to 40%, compared to the 50% seen with subcutaneous or intramuscular preparations.
Usual Adult Dose for Hypercalcemia:
4 intl units/kg (rounded to the next higher 5 intl units) subcutaneously or intramuscularly every 12 hours. The maximum dosage should not exceed 545 intl units per dose. If a response to the 4 intl units/kg dose is not observed in 1 to 2 days, 8 intl units/kg (rounded to the next higher 5 intl units) may be given subcutaneously or intramuscularly every 12 hours. The dosing frequency may be increased to every 6 hours, if needed. The maximum dosage should not exceed 1090 intl units per dose. Therapy is generally 5 days or fewer. A 2 mg/dl reduction in plasma calcium level is usually noted and maintained for 2 to 4 days. Thereafter, the effect diminishes.
Usual Adult Dose for Osteoporosis:
100 intl units given every other day or 50 intl units given once a day either subcutaneously or intramuscularly. Injectable doses may be increased to 200 or 400 intl units once per day, as required.
200 intl units may be given intranasally once a day, alternating nostrils daily.
Therapy is generally long-term, lasting months or years.
Usual Adult Dose for Osteogenesis Imperfecta Tarda:
50 intl units given subcutaneously three times a week. Dosages may be increased to 100 intl units depending on tolerance of side effects and efficacy of the 50 intl units dose therapy.
