How should I take oral cyanocobalamin?
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Do not swallow a lozenge or sublingual tablet whole. Allow it to dissolve in your mouth without chewing.
The sublingual tablet should be placed under your tongue where it will dissolve.
Do not crush, chew, or break an extended-release tablet. Swallow it whole.
Take the extended-release tablet with a full glass of water.
To be sure cyanocobalamin is helping your condition, your blood will need to be tested every 3 to 6 months. This will help your doctor determine the correct dose and how long to treat you with cyanocobalamin.
To treat pernicious anemia, you will have to use this medication on a regular basis for the rest of your life. Not using the medication can lead to irreversible nerve damage in your spinal cord.
Pernicious anemia is also treated with folic acid to help maintain red blood cells. However, folic acid will not treat Vitamin B12 deficiency and will not prevent possible damage to the spinal cord. Take all of your medications as directed.
Store at room temperature away from moisture, heat, and light.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
