My husband was seizure-free for 8 years and was on Oxcarbazepine OD (extended release) 900 mg. He suffered an attack because he delayed his dose by 8 hours one day, so he took his pill before bed instead of lunch time. He had an attack within 15 minutes of waking the next day.

His doctor has now prescribed Trileptal 1150 mg (600 mg at night, 450 mg in the morning). It's been 2 weeks but he still gets auras and we are constantly anxious he may have a seizure again despite taking the medicines at the right time every day. Can anyone recommend if a 12 hour gap is ideal between the 2 doses or less/more?

He is also on Frisium 5mg at night for the next 10 days.
