Eligen B12™ Side Effects

In clinical trials, there were no serious side effects.

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.

Before using Eligen B12™, tell your doctor or pharmacist if you:

  • Are or may be allergic to cyanocobalamin (vitamin B12) or cobalt
  • Have an iron or folic acid deficiency
  • Have kidney or liver disease
  • Have low potassium blood levels (hypokalemia) or gout
  • Have a blood disorder called polycythemia vera
  • Have an eye disease called hereditary optic nerve atrophy (Leber’s disease)
  • Are receiving any medication or treatment that affects bone marrow
  • 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.
