Cyanocobalamin Tablets contain cyanocobalamin, which is known as vitamin B12.
Cyanocobalamin contains cobalt.
Most people get enough vitamin B12 from their food, but if you have had stomach surgery, or certain diseases of the intestines, or a restricted diet, you may not absorb enough vitamin B12.
Lack of vitamin B12 in the body causes a disease called pernicious anaemia (reduction in the number of red blood cells) which is often treated with vitamin B12 injections.
Cyanocobalamin tablets are used to treat vitamin B12 deficiency when injections cannot be used.
- if you are allergic to cyanocobalamin or any of the other ingredients of this medicine (listed in section 6).
Those who have an allergic reaction to Cyanocobalamin by injection are often able to take Cyanocobalamin tablets without problems.
- Talk to your doctor or pharmacist before taking Cyanocobalamin Tablets.
- Talk to your doctor if you have a known cobalt allergy.
- If you have any other medical conditions, speak to your doctor before you take these tablets.
Your doctor will want to monitor your response to this medicine carefully, particularly if you are young or elderly.
This will probably involve regular blood tests every three months for 18 months and then annually.
