Welcome to HeathcareMagic forum.
Having a seizure
can lead to aspiration ,where the contents from the mouth trickle down the throat causing infection and obstruction of respiratory tract
later , the cause of the seizure may be anything.
As the doctors have examined you, I feel they have not missed out on anything else, I suggest you continue the antibiotics, as you have started them just a while back , with time they will act well, so please wait and continue the dose.
Wish you good health
