Eligen B12™ is indicated for the dietary management of patients who have a diagnosed vitamin B12 deficiency that cannot be managed by a modification of the normal diet alone. This deficiency can be caused by a range of conditions in which there is an impaired capacity to absorb vitamin B12.

Important Safety Information

You should not take Eligen B12™ if you are allergic to vitamin B12, cobalt, or any ingredient of Eligen B12™.

You should not take Eligen B12™ if you have Leber’s disease, which your doctor may refer to as hereditary optic nerve atrophy. Cyanocobalamin can lead to optic nerve damage (and possibly blindness) in people with Leber’s disease.

  • Are or may be allergic to cyanocobalamin (vitamin B12) or cobalt

  • Have other vitamin/mineral deficiencies (especially folic acid and iron)

Get emergency medical help if you have any of these signs of a serious reaction: muscle cramps, weakness or irregular heartbeat, hives, difficulty breathing, swelling of your face, lips, tongue or throat.

Call your doctor at once if you have a serious side effect, such as feeling short of breath, even with mild exertion, sudden vision changes or slurred speech.

Less serious side effects may include diarrhea, itching or rash.

Before using Eligen B12™ tell your doctor or pharmacist all of the medicines you are taking, especially methotrexate, pyrimethamine, any antibiotics, and any vitamins.
