Femibion – Use | Dose | Side Effects

Femibion is a pregnancy multivitamin. There are two types of Femibion (Femibion 1 and Femibion 2). Femibion 1 can be used from the time you plan to become pregnant until the end of the third month of pregnancy. Femibion 2 can be used from the fourth month of pregnancy until the end of breastfeeding.

Femibion 1 is a medicine that contains the following vitamins:

  • Vitamin B1 (thiamine)
  • Vitamin B3 (nicotinamide)
  • Vitamin B5 (pantothenic acid)
  • Vitamin B6
  • Vitamin B7 (biotin)
  • Vitamin B9 (folic acid)
  • Vitamin B12
  • L-methylfolate (the active form of folic acid)
  • Vitamin E
  • Vitamin C
  • Iodine

This medicine contains the active form of folic acid. Folic acid is not active in the body, but through a number of processes in your body it is converted to L-methylfolate which then exerts its benefits in the body.

Some studies shown that a large number of women converts only a small part of folic acid into its active form. Therefore, using this multivitamin helps you avoid the lack of folic acid, because it contains folic acid in its active form.

Folic acid is essential during pregnancy and helps prevent neural tube defects. Folic acid needs in pregnant women are significantly increased. It is almost impossible to get the recommended amounts of this vitamin just from food, therefore you should use multivitamin.

This medicine also contains iodine which is essential for normal mental development. However, because it contains iodine, Femibion must be used only with extra precautions in pregnant women with thyroid problems.


Femibion should be avoided in pregnant women allergic to any of the vitamins contained in this medicine. If you are experiencing symptoms, such as:

  • rash,
  • itching,
  • redness,

discontinue use and call your doctor.

It should be used with extra precautions in pregnant women with the thyroid problems.

It should be avoided in patients who have a high level of vitamins in the blood (hypervitaminosis).

If you are already taking another multivitamin, you should not ever start usisn Femibion on your own. Talk to your doctor about which multivitamin you need to take. Concomitant use of more than one multivitamins in pregnant women, can lead to hypervitaminosis and can harm your baby.
