What is CaloMist?
CaloMist nasal spray contains cyanocobalamin, a man-made form of vitamin B12. Vitamin B12 is important for growth, cell reproduction, blood formation, and protein and tissue synthesis.
CaloMist nasal spray is used to treat vitamin B12 deficiency in people with pernicious anemia and other conditions.
CaloMist nasal spray is usually given after treatment with an injection form of this medicine.
CaloMist may also be used for purposes not listed in this medication guide.
Warnings
You should not use this medicine if you are allergic to cobalt, or if you have Leber's disease.
To treat pernicious anemia, you will have to use CaloMist on a regular basis for the rest of your life. Not using the medication can lead to irreversible nerve damage in your spinal cord.
Pernicious anemia is also treated with folic acid to help maintain red blood cells. However, folic acid will not treat Vitamin B12 deficiency and will not prevent possible damage to the spinal cord. Use all of your medications as directed.
Tell your doctor if you develop nasal congestion, a cold, or allergies. The nasal spray may not work as well if you are congested.
Before taking this medicine
You should not use CaloMist if you are allergic to cyanocobalamin or cobalt, or if you have Leber's disease (an inherited form of vision loss). Cyanocobalamin can lead to optic nerve damage (and possibly blindness) in people with Leber's disease.
To make sure CaloMist is safe for you, tell your doctor if you have:
cold or allergy symptoms that affect your nose (sinus congestion, sneezing);
kidney or liver disease;
iron or folic acid deficiency;
any type of infection; or
if you are receiving any medication or treatment that affects bone marrow.
FDA pregnancy category C. It is not known whether CaloMist will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medicine.
Cyanocobalamin can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
