I think you would require a note signed by your neurologist, epileptologist, or even a general practitioner to get out of jury duty. There are legitimate reasons for this, even when you're going through changing medicines, and so forth. You may experience serious side effects that makes you irritable, suicidal, or to simplify it, it basically screws your emotions up. It may also make you have a difficult time to think, and make critical decisions that will mess with your judgments.
Listen, I am not a medical professional nor a lawyer, but let me elaborate my opinion. Why would you want to serve? First, if you have difficult to control seizures such as complex partials or generalized seizures, then you'd be confused and wouldn't hear the case. It would be dangerous, if you have terrible side effects that affects your emotions, critical thinking, or even judgments; because that could be dangerous for the person on trial, assuming it's something like this. Would you want somebody on a jury, judging you, if they had some form of medical problem like this? It's nothing personal, but if you can qualify to serve and your doctor offers you recommendations, and says it's okay, then it would be a good thing.
I understand that you do not like labels and same applies to me, I do not like labels. But, as I just stated, that can be extremely dangerous, and perhaps even illegal, if you do not disclose this information to the court. So, just to be safe you should at least call your doctor and ask for advice. Perhaps he will say it's okay to serve, or give you a note to get you off of the jury. You know, I doubt that would do anything to your career, if you were to work for government, just dangerous jobs that you shouldn't work for anyway. These jobs people shouldn't join, if they have epilepsy at least in my opinion: firefighter, police, pilots, military, and perhaps a couple of others. If you were to get an education, and become a judge, lawyer, or even do simple office jobs that doesn't threaten anybody life then it should be safe. Usually you would be protected under the ADA (Americans with disabilities act), unless the career was dangerous and people depended on you, like the military.

You should ask your doctor, a lawyer, or even research your state and federal laws just to be on the safe side. But, as I said if you don't tell them then it could perhaps be illegal, you don't want to do that! For driving, usually medicine side effects doesn't stop you unless it's something where you may fall asleep at the wheel. I doubt they would label you as disabled, unless you just had a seizure. State laws varies, and if you're seizure free for X months or year then you should be able to drive. I doubt they would stop that.
They may just say you're unfit at the moment, instead of saying you're disabled for life. So, perhaps in the future they would call you back to jury duty. I don't know. Others may have better advice! Good luck though.
P.S. if you see any grammar errors, please let me know. I've been trying to improve my grammar. <3
