How should I use cyanocobalamin nasal?
Cyanocobalamin nasal is usually given once per week. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
You may need blood tests every 3 to 6 months, and your doctor may change your dose based on the results.
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.
Tell your doctor if you have sinus congestion. This medicine may not work as well if you have a stuffy nose.
For 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 anemia or irreversible nerve damage.
Pernicious anemia is also treated with folic acid to help maintain red blood cells. Folic acid alone will not treat Vitamin B12 deficiency or prevent possible damage to the spinal cord. Use all medications as directed.
Store in an upright position at room temperature. Protect from light and do not freeze.
