Epilepsy is a chronic disease with a long course and is prone to recurrence. The majority of the antiepileptic drugs currently in use are only for seizure control, so patients need to take the drugs for a longer period of time and not “fish for three days and sunbathe for two days”. Some patients do not have an attack for a few months and take their medication intermittently, some even stop taking their medication without permission, which can easily cause serious recurrence of the disease and cause more difficulties in treatment. If the patient can remain seizure-free for more than 2 to 3 years, the dose of medication can be gradually reduced over a period of six months to a year under the guidance of a doctor, and then completely discontinued. For adolescent patients who are in their adolescent developmental period, it is more prudent to reduce the dosage and discontinue the medication because the disease is more likely to recur during this period and it is better to delay the discontinuation of medication.
