Welcome @tatiana01. I moved your message to this discussion so you can meet other members who are talking about epilepsy and seizures. I hope that @carol94 @jeans @sall @lucky12 or other members may be able to answer your questions about medications no longer working and what other treatment options that have had or considered.

In the meantime, here is some information from Mayo Clinic on Vagus nerve stimulation http://www.mayoclinic.org/tests-procedures/vagus-nerve-stimulation/home/ovc-20167755

What medications have you already had? And what treatment options is your doctor suggesting?

He was on levetracitram 500mg time release. The doctor wanted him to take 1000mg but he could not handle it, the mood extremes etc. The last visit she started him on vimpat and was weening him off the levetracitram. We finally just decided that both meds still was causing difficulty. So far with vimpat 100mg morning and night has been working okay so far.
