Is folic acid safe for pregnant and breastfeeding women?
There is no adequate research on the risks of using this drug in pregnant or nursing women. Always consult your doctor to consider the potential benefits and risks before using this medicine. This drug is included in the risk of pregnancy category A according to the US Food and Drugs Administration (FDA).
The following are references to pregnancy risk categories according to the FDA:
- A = No risk,
- B = No risk in some studies,
- C = Maybe risky,
- D = There is positive evidence of risk,
- X = Contraindications,
- N = Unknown
During pregnancy, folic acid deficiency is something that often attacks pregnant women. This can result in imperfect formation in the fetus, which can cause the baby to be deformed at birth. Therefore, as recommended by the US Center for Disease Control published in one of Drugs.com's articles, women who are pregnant are actually advised to consume as much as 0.4 mg of folic acid every day. Meanwhile, if a pregnant woman has a history of giving birth to a baby with congenital defects such as failure of neural tube closure, the folate dose given will be higher at 4 mg per day.
Meanwhile, for nursing mothers, consuming folic acid is something that does not harm the mother and baby. Because, although folic acid can come out with breast milk and consumed by breastfed babies, folic acid is actually needed to help meet nutrition in infants.
So, channeling folic acid through breast milk to babies who breastfeed is actually a good thing. In addition, no side effects were detected in the mother and baby after consuming folic acid.
