I am 32, female. Does epilepsy impact my future pregnancy?

Question

Hi doctor,

I am a 32-year-old female with focal epilepsy controlled on Lamotrigine 200 mg. I have been seizure-free for two years and am now trying to conceive. I take 4 mg of folic acid daily, but I am still nervous about risks.

Should my Lamotrigine dose change during pregnancy?
How often do women have breakthrough seizures while pregnant?
What’s the safest monitoring plan for both me and the baby?

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

It is completely natural to feel anxious when planning a pregnancy with a history of epilepsy, but you are already taking important steps in the right direction. Being seizure-free for two years and taking Folic acid are both major positives. Lamotrigine is generally considered one of the safer anti-seizure medicines during pregnancy, but close monitoring is essential. Pregnancy can alter the way your body processes Lamotrigine, which may affect blood levels and seizure control.

To prepare safely, a pre-conception review with your neurologist is strongly advised to check:

Whether your current dose is optimal.
Baseline liver and kidney function tests.
Serum lamotrigine levels.
Routine monitoring during pregnancy is recommended.
A high-resolution fetal anomaly scan around 18 to 20 weeks and regular visits with both your neurologist and obstetrician will be part of care.

Do not stop or change Lamotrigine on your own. During pregnancy, Lamotrigine levels often fall, especially in the second and third trimesters, so your doctor may adjust the dose to prevent breakthrough seizures. Folic acid (4 mg daily) is appropriate and should be continued at least through the first trimester. Report any change in seizure pattern immediately.

Preventive steps include:

Maintaining regular sleep.
Staying well hydrated.
Reducing stress.
Avoiding missed doses is important.

Keeping a seizure diary and educating your partner or caregiver on seizure management can also help. Please continue close follow-up with your neurologist and obstetrician before and during pregnancy. You are already on the right track. Stay consistent with your care plan and do not hesitate to seek guidance whenever needed.

Thank you.
