🟪 Intranasal vitamin B₁₂ requires adequate mucosal absorption, and gentle massage of the nose helps distribute the medication across the nasal mucosa for optimal uptake.

🟪 This improves the effectiveness of therapy for clients with malabsorption syndrome, who cannot absorb B₁₂ adequately through the gastrointestinal tract.

🟪 Gentle massage also prevents medication runoff from the nostril, ensuring the full therapeutic dose is absorbed.

🟪 Intranasal formulations depend on contact time with the mucosa, making post-administration massage an important step.

🟪 Proper technique reduces risk of treatment failure and prevents recurrence of pernicious anemia symptoms.

🟪 Teaching this ensures the client achieves stable and consistent B₁₂ levels.

“Take this medication once per day.”

🟪 Intranasal vitamin B₁₂ is administered once weekly, not daily.

🟪 Daily use can cause mucosal irritation and is unnecessary for maintaining adequate B₁₂ levels.

“Drink a hot liquid after administering the medication.”

🟪 Hot liquids can increase nasal blood flow and cause medication to drain or be absorbed unevenly.

🟪 This reduces the medication’s effectiveness and is not recommended.

“Store this medication in the refrigerator.”

🟪 Intranasal vitamin B₁₂ should be stored at room temperature, not refrigerated.

🟪 Cold temperature can alter spray consistency and reduce proper delivery
