Thanks for your question
chrono contains Sodium Valporate and its a broad spectrum anti epileptic drug that is it can be used in different type of seizures.
There has been debate whether to start Anti Epileptic Drugs even after single episode, but most of doctors prefer to start the therapy to remain on safer side so you are taking right medicine and right prescription.
Dose prescribed is also sufficient dose that is 1000 mg per day.
It has been a year and there is no episode so far, present guidelines advocate to continue drugs for at least 3 years without episodes. So as per my opinion you should not think to stop the drug or to decrease the dose (against the advise), as there is risk of rebound seizure activity.
Encorate chrono is a safe drugs and there are no major serious side effects of this drug, usually Nausea
, reversible alopecia
, weight gain may be seen but they are tolerated easily.
So please don't think to reduce the dose.
