Generic name: CYANOCOBALAMIN 25ug in 0.1mL
Dosage form: nasal spray, metered
Drug class: Vitamins

Medically reviewed by Last updated on Jan 17, 2022.

Recommended Dose

The recommended initial dose of CaloMist is one spray in each nostril once daily (25 mcg per nostril, total daily dose 50 mcg). The dose should be increased to one spray in each nostril twice daily (total daily dose 100 mcg) for patients with an inadequate response to once daily dosing.

The dosing of CaloMist and other intranasal medications should be separated by several hours, and these patients should have more frequent monitoring of vitamin B12 concentrations because of the potential for erratic absorption.

Priming (Activation) of Pump

The pump must be primed before the bottle is used for the first time. To prime the pump, place the nozzle between the first and second finger with the thumb on the bottom of the bottle. Pump the unit firmly and quickly then repeat this priming an additional 6 times for a total of 7 priming sprays. Now the nasal spray is ready for first-time use. If 5 or more days elapse since last use, the pump must be re-primed with two re-priming sprays.

Additional instructions are provided in the patient instruction sheet [see Patient Counseling Information (17.2)].
