Hello,
Welcome to health care magic. I am Dr Alok Sinha, MD Psychiatry from India. I can understand your concern. I will try my best to answer your query.
Levepil (
Levetiracetam) is a good antiepileptic drug. As
epilepsy is a serious and long lasting illness of brain its medicines should be continued for many years. These medicines have prophylactic effect and it prevents epilepsy from occurring again. Your brother's doctor understands the requirement of medicine hence he continued it. Apparently you are not convinced that your brother is currently well on maintenance medication. If an epileptic person stops medicines there are chances of relapse. If there is some structural defect or history of some epileptogenic focus in brain then the chances of recurrence is much more. Here no information is provided about
MRI, EEG brain etc. So I can not say whether his brain is OK or not.
If a person has relapse of illness in past then it is unwise to discontinue medication, but if the person is stable and
seizure free then doses may be gradually tapered (which your brother's doctor is doing that is reduction from 500 mg to 250 mg dose). When to stop medicines, it should be decided by treating physician. As such the doses are very mild and no serious side effects with this dose is observed.
I humbly suggest you to have faith in the treating doctor.
I hope it answers your question. I wish your brother all the best.
