Talk to your doctor. You may be getting too much, which gives you those effects. Do you have the same doctor, or a new one? There must be a reason?

When any AED ( AntiEpileptic Drug ) levels are low and the Dr. Doesn’t increase the dose, there’s a chance that yours seizures will come back. Your Dr. Is just making sure your seizures stay under controlled.

It’s all relative. What time of day was it compared to others draws? When had eaten? Did you miss a dose in 24 hrs? Exercise last? …my kepra can be very low and I’m up to speed. Is their a trend line for your results online?

You have the ultimate say here. Can you speak with your doc about your concern? If you're uncomfortable, maybe you need another MD. Its hard to be assertive sometimes, but I think your argument is very reasonable. Therapeutic doses are in fact different for everyone. Research gives us a range, based on trials that historically involved a very narrow demographic (white, male). Trust your body, and talk to your provider. You can always up the dose IF you begin experiencing symptoms. I hope this is useful.

The only time they increase the meds is when your blood levels are low.
