1. What Cytamen is for
Cytamen is a form of Vitamin B12, an essential vitamin which is needed for the production of red blood cells.
Cytamen is used to prevent and treat certain types of anaemia, including Addisonian pernicious anaemia, and other kinds of anaemia which result from a deficiency of Vitamin B12.
It is also used for a test called the Schilling Test, which measures your ability to absorb Vitamin B12 from the bowel.
2. Before you are given Cytamen
You should not be given Cytamen if:
• You are allergic to the active ingredient, cyanocobalamin
• You are allergic to any of the other ingredients of Cytamen (see section 6.)
• You have a condition called toxic amblyopia (poor vision which may be due to Vitamin B12 deficiency).
If any of the above applies to you talk to
your doctor or nurse.
Check with your doctor before being given
Cytamen if:
• You are pregnant, planning to become pregnant or breast-feeding
• You have megaloblastic anaemia. This is a blood disorder where you have larger than normal blood cells
Tell your doctor if you are taking any of the following medicines:
• Antibiotics (for treating infections) or antimetabolites (medicines which stop cells dividing, such as mercaptopurine for leukaemia), as these treatments may interfere with tests to measure the levels of Vitamin B12 in your blood or urine
• An antibiotic called chloramphenicol, as you may not respond well to Cytamen
• Oral contraceptives 'The Pill'
• Any other medicine, including medicines obtained without a prescription.
If any of the above applies to you talk to your doctor or nurse.
Pregnancy and breast-feeding Cytamen should not be used in pregnancy for treating a kind of anaemia called megaloblastic anaemia, unless you also have a Vitamin B12 deficiency.
Cytamen is found in breast-milk but it is unlikely that it will harm your baby.
If you are pregnant, trying to become pregnant or are breast-feeding, ask your doctor or nurse for advice before being given Cytamen.
Driving and using machines Cytamen may cause dizziness. If this happens to you, do not drive or use machinery.
3. How you will be given Cytamen Important:
