Can Taking Lamitor 100 And Dicorate Be Safe For Fits?

Hi doctor, my husband got fits at first time during going to a school trip. Later he was got second time after 1 year. Third time he was got while he was 22. Now he is 30. He didn't get any fits around 8 years. He is taking medicine regularly(lamitor 100 and dicorate er500). But if he didn't take for 2 days means he is suffering by head ache. Should he continue the medicine throught out the life. We want to recheck up his health. Pls suggest me e
