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.

How is Depo-Cobolin (cyanocobalamin injection) given?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Cyanocobalamin injection is injected into a muscle or under the skin. You may be shown how to use injections at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles and syringes.
Use a disposable needle only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Your dose needs may change if you become pregnant, if you breast-feed, or if you eat a vegetarian diet. Tell your doctor about any changes in your diet or medical condition.
While using cyanocobalamin injection, you may need frequent blood tests.
Use cyanocobalamin injection regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
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.
To treat pernicious anemia, you may have to use cyanocobalamin for the rest of your life. Do not stop using the medicine unless your doctor tells you to. Untreated vitamin B12 deficiency can lead to a recurrence of anemia and irreversible nerve damage.
