Epifast 500 Tablet contains levetiracetam, which is generally considered one of the safer anti-seizure medicines during pregnancy. Several studies have not found an increased risk of major birth defects compared with the usual risk in pregnancy. There is also no clear evidence that levetiracetam increases the risk of serious harm to the foetus or the baby's life. However, no medicine is completely risk-free during pregnancy, and the effects can vary depending on the dose and the mother's health. It is also important to remember that uncontrolled seizures can be harmful to both the mother and baby. Therefore, if you are pregnant, do not stop taking Epifast 500 Tablet suddenly or change the dose without your doctor's advice. Your doctor can assess the benefits and possible risks and advise you on the safest treatment during pregnancy.
