About Naso B12 Nasal Spray

Naso B12 Nasal Spray belongs to the class of vitamins primarily used to treat or prevent vitamin B12 deficiency. Vitamin B12 deficiency occurs when the body has lower levels of vitamin B12 than normal. Symptoms include fatigue, breathlessness, numbness, poor balance, and memory problems.

Naso B12 Nasal Spray contains Methylcobalamin, a form of vitamin B12, which helps to protect the nerves from damage and promotes blood cell production. It regulates body functions, such as cell multiplication, blood formation, and protein synthesis.

Naso B12 Nasal Spray must be taken as directed by the healthcare professional or as per leaflet information for maximum benefit. In some cases, Naso B12 Nasal Spray may cause headache, nausea, runny nose, and infections (such as sore throat and the common cold). The majority of these side effects subside over time without the need for medical intervention. However, please see a doctor if the side effects persist or worsen.

Let the doctor know if you are allergic to Methylcobalamin or any other medications. Inform the doctor if you have breathing problems such as a stuffy nose, hay fever or allergic rhinitis, or upper respiratory infection. Consult the doctor if you are pregnant, planning for pregnancy, or are breastfeeding. Keep your doctor informed about your present and past medical history and ongoing medicines to rule out any side effects.
