1. What Folic Acid Tablets are and what they are used for
These tablets contain the active ingredient, folic acid. Folic acid is the chemical name for Vitamin B9. It is necessary for
the normal production of blood cells.

Folic Acid Tablets are used for the treatment of certain types of anaemia. They are also used to help prevent the
breakdown of red blood cells which can occur as a result of renal (kidney) dialysis or certain other conditions.

2. Before you take Folic Acid Tablets
Some people must not take these tablets. Talk to your doctor if:
• You know you are allergic to folic acid or to any of the other ingredients (these are listed in section 6)
• You are suffering from pernicious anaemia or any other vitamin B12 deficiency unless you have already been treated
with a drug called hydroxocobalamin
• You have cancer.

You must be especially careful if:
• You have an intolerance to some sugars. These tablets contain small amounts of lactose and sucrose.

If any of the conditions above apply to you, please discuss your treatment with your doctor before taking this
m edicine.
