How is pernicious anemia (PA) treated?

ANSWER

Vitamins you buy at the drug store don’t have enough B-12 in them to treat PA. Your doctor will need to prescribe a special supplement to you. This is often given in a shot. At first, you may need to have one every other day. Over time, you may be able to cut back to once a month.

Extra B-12 can also be prescribed as a pill, nose spray, nasal gel, or medicine you put under your tongue.

Your doctor will likely also suggest some changes to your diet so you can get more B-12.
