When should you stop taking folic acid during pregnancy?

Folic acid should generally be taken until the end of the third month after pregnancy. Folic acid helps prevent fetal neural tube defects. Taking folic acid during early pregnancy not only reduces the risk of neural tube defects but also helps prevent anemia during pregnancy. Pregnant women with poor folic acid metabolism or a history of pregnancy complications should take higher doses of folic acid. If a woman has previously given birth to a baby with neural tube defects, she can continue taking folic acid throughout the entire pregnancy until delivery. However, pregnant women who have epilepsy and are taking sodium valproate for a prolonged period should also take folic acid before delivery.
