In a patient planning pregnancy who is taking levetiracetam, which folic acid regimen is recommended?

• A. Start 0.4 mg folic acid before conception
• B. Start 1 mg folic acid before conception
• C. Start 2 mg folic acid before conception
• D. Start 5 mg folic acid before conception and continue through to at least 12 weeks

Answer: (D)

Neural tube defects can form very early in pregnancy, often before many women know they’re pregnant. For women with epilepsy who are planning conception and will continue antiepileptic therapy, providing enough folate during this critical period reduces that risk. The recommended approach is a high-dose folic acid regimen: take 5 mg daily starting before conception and continue through at least the end of the first trimester (around 12 weeks). This ensures ample folate during neural tube closure, which occurs in the early weeks of gestation. Lower doses, such as 0.4 mg (general population) or 1–2 mg, are not considered sufficient in this high-risk context.
