What is NASCOBAL®?
NASCOBAL® (Cyanocobalamin, USP) Nasal Spray is a prescription medicine used as a supplement to treat vitamin B12 deficiency.
IMPORTANT SAFETY INFORMATION for NASCOBAL®
Do not use NASCOBAL® if you are allergic to cobalt, vitamin B12, or any of the ingredients in NASCOBAL®. Severe allergic reactions and death have occurred with other types of vitamin B12 supplements.
If you have Leber’s disease, NASCOBAL® can cause serious nerve damage in your eyes. Talk to your doctor if you have vision problems before or during treatment.
Life-threatening side effects may occur in people with a certain kind of anemia (a blood problem), treated aggressively with vitamin B12. Additionally, taking a drug called folic acid in place of vitamin B12 can lead to worsening and permanent nerve damage.
Your doctor will check your blood before starting NASCOBAL® and during therapy. It is important to return for follow-up visits as directed by your doctor to make sure NASCOBAL® is working.
Since NASCOBAL® is inhaled by nose, tell your doctor if you have breathing problems such as stuffy nose, allergic rhinitis, or upper respiratory infection. Your doctor may choose to delay your treatment.
Tell your doctor if you are pregnant or planning to become pregnant (it is not known if NASCOBAL® will harm your unborn baby). However, vitamin B12 is an essential vitamin and requirements are increased during pregnancy. Tell your doctor if you are breastfeeding.
Tell your doctor about all of the medicines you take, both before and during your treatment with NASCOBAL®. Certain medicines can affect blood test results and how NASCOBAL® works.
Side effects include weakness, headache, sore throat, common cold, swollen tongue, nausea, tingling and rhinitis.
These are not all the possible side effects of NASCOBAL®. Talk to your doctor about any side effects you experience.
