Epilepsy is usually fully curable. It is known that drugs given for epilepsy when patient is pregnant can harm the baby. The risk is not great only 5-6%, meaning in 95% cases nothing will happen.
Topomac is a new drug and we don't know whether the risk is more or less when using Topomac. The usual thing would be to delay next pregnancy until Topomac is omitted. If a person is 3 years fit free we can taper and stop medicines. If Topomac cannot be stopped it would be better to use another of the older drugs whose side effects are better known. The doctors in Apollo can assay for changing or stopping Topomac depending on her condition.
