that is a good question, i am not a doctor but myself was bumped up on a drug when in my mind i did not need the increase. i am going to fight it to have it lowered it was increased 25 mg. i hear and see people on this platform that use the same drug with higher mg. but i want off some of these drugs not adding to them. mine is also a seizure med and i take two others for the same reason. have not had a seizure now in months. wish i could give you the answer, myself i am taking like 26 meds a day and think i maybe need half but i am not the doctor and do not see the study on every med i take , wish you luck on your finding an answer, also sending a prayer for you too------------sent. Have a blessed day.
