Hi, How are you doing I think you should immediately meet your neurologist & tell him that you are trying for pregnacy. There are many safer alternative medicines in market. Common side effects are Bowel problems (Constipation,diarrhoea), dizziness, headache,stomach pain,nausea,tiredness,vomiting This is Category C drug- only animal studies are available , which suggest irreversible congenital anomalies in babies. Only if no other alternative safer drug available only if benefit of using is more than risk of stopping , you should use it. Before trying for pregnancy it is better to get it to control level, avoid the predisposing factors like - sleeplessness, too much stress, straining reading on screen for too long etc. Use the safest drug in pregnancy & keep it to lowest dose. Finally we want a healthy baby & healthy mother ! Suddenly if you stop medications you may throw convulsions again, cannot be predicted. Gradually reduce dose under neurologist supervision. Hope I have cleared your query All the best Dr.Balakrishnan
