How should I take oral cyanocobalamin?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Carefully follow instructions about whether to take your cyanocobalamin with or without food.
Your dose needs may change if you become pregnant, if you breastfeed, or if you eat a vegetarian diet. Tell your doctor about any changes in your diet or medical condition.
Swallow the extended-release tablet whole and do not crush, chew, or break it. Take with a full glass of water.
Do not swallow a lozenge or sublingual tablet whole. Allow it to dissolve in your mouth without chewing. Cyanocobalamin sublingual tablet or liquid should be placed under your tongue.
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.
To treat pernicious anemia, you will have to use cyanocobalamin on a regular basis for the rest of your life. Not using the medication can lead to irreversible nerve damage in your spinal cord.
You may need frequent medical tests to help your doctor determine how long to treat you with cyanocobalamin. Using certain other medicines while taking cyanocobalamin may affect the results of these tests.
Store at room temperature away from moisture, heat, and light.
