How should I use cyanocobalamin nasal?
Cyanocobalamin nasal is usually given once per week. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
This medicine comes with patient instructions for safe and effective use, and directions for priming the nasal spray. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
To use the nasal spray:
Blow your nose gently. Keep your head upright and insert the tip of bottle into one nostril. Press your other nostril closed with your finger. Spray the medicine into your nose and gently sniff at the same time. Then use the spray in your other nostril.
Do not blow your nose for at least a few minutes after using the nasal spray.
Wait several hours after using cyanocobalamin nasal spray before using any other nasal medicines your doctor has prescribed.
Clean the tip of the spray with a clean tissue and recap.
Tell your doctor if you have a prolonged illness that causes sinus congestion. Cyanocobalamin nasal may not work as well if you have a stuffy nose.
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 nasal, you may need blood tests every 3 to 6 months. Based on the results of these tests, your doctor may occasionally change your dose or recommend a cyanocobalamin injection.
Use cyanocobalamin nasal regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
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.
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.
Store in an upright position at room temperature, away from moisture, heat, and light. Do not freeze.
