Oxetol 300 side effects

[Manutr]

My wife had partial-seizure normally occuring in every 26-28 days once. She is in treatment for almost 2 years now. But not much improvement. Earlier she was on Keppra 500 and now she is in Oxetol150 and for the last 2 months Oxetol 300 twice in a day. She is having headache every day and always sleepy. She got a rash on neck also after some 10 days taking Oxetol (not sure is it due to Oxetol). So may I know Oxetol 300 is a good and recommended medicine to treat partial-seizure and these side affects are common. She is getting fear like symptoms sometimes. So all these are normal side affects and it will get right after some days taking or the body become ready to accept Oxetol ?

And final question, is this partial seizure can be cured completely ? what else we need to do improve the treatment. Took MRI scan and nothing found other than Sinus. Blood levels are fine.

Thanks,
