What is NASCOBAL®?
NASCOBAL® (Cyanocobalamin, USP) Nasal Spray is a prescription medicine used as a supplement to treat vitamin B12 deficiency. People who have had weight loss (bariatric) surgery may not absorb enough vitamin B12 from food, and are at increased risk of developing vitamin B12 deficiency.
Why NASCOBAL® is a good option:
- Only FDA-approved vitamin B12 nasal spray
- Simple, once-weekly dosing*
- Fewer visits to the doctor’s office for vitamin B12 dose
- Not a painful injection
- Tasteless and odorless fine mist
- Increased and maintained vitamin B12 levels in clinical trials
- Absorbed directly into the bloodstream—designed to bypass the stomach and digestive tract
- Self-administered

Follow the steps below to see how simple it is to use NASCOBAL®
- The unit contains only 1 spray:
DO NOT prime before use - Blow nose gently to clear both nostrils
- Hold the unit with your thumb, supporting it at the bottom, and your index and middle fingers on either side of the nozzle
