Important Safety Information for Vitamin B12

Vitamin B12 injections are a compounded medication and are not FDA-approved in the way a standard prescription drug is. A licensed SD Clinic provider can confirm whether B12 injections make sense for you based on your health history.

Generally well tolerated

Vitamin B12 injections are considered very safe for most people, with no major side effects at appropriate doses.

Allergic reactions are rare, but possible

A small number of people may have an allergic reaction or sensitivity to B12 injections. Contact your provider promptly if you notice any unusual symptoms after an injection.

Low risk of excess buildup

Your body only absorbs the amount of B12 it needs and eliminates the rest through urine, which keeps the risk of toxicity from too much B12 quite low.

Not necessarily needed for everyone

B12 injections are generally intended for people with a diagnosed or suspected B12 deficiency. If your levels are already sufficient, injections may not add meaningful benefit β€” your provider can help you determine whether testing or treatment makes sense for you.
