How To Use B12

B12 comes in the form of a liquid injection solution. Your health care professional will give you the injection under your skin or into a muscle. You may need to receive injections regularly, maybe even for the rest of your life. 

Keep all your appointments with your healthcare professional for cyanocobalamin injection, even if you feel well. If you stop the treatment, your anemia may come back and result in irreversible nerve damage.

Missed dose: If you miss a dose of your cyanocobalamin injection, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take the next scheduled injection according to your regular dosing schedule. Do not take an extra injection to make up for a missed dose.

Storage: Your healthcare professional will store cyanocobalamin injection (B 12) appropriately.

Unused medicine: Your health care professional will dispose of unused or expired B12 injection appropriately. If you are using the oral or nasal spray forms of B12, do not throw unused or expired medicine in the trash or toilet. The safest way to dispose of expired or unneeded medications is through a drug take-back program. Learn more about proper medication disposal
