My Name Is Switch...How Are You? My Girlfriend Of Six

My name is Switch...How are you?
My girlfriend of six years has been having seizures for about 2 years now, on and off that is... Over a year maybe four five episodes where she'll have one, then another and forget the first and up to three where she still didn't remember the first or second! All this over a period of 48 hrs.
Know here comes the honesty! She put it down to the homemade smoking herbs from the shop, though she also had an episode when she was at a party three 12 months ago, she was given some ice to smoke !
Two days later she was having them episodes.
She has recently come forward and said she is allergic to antiseptic ( the stuff they use in hospital to knock her out when she has day surgery) .
When she had it in hospital they find it hard to wake her. To hard...
Anyhow! What are the odds it's found in these substances and could be the cause to a larger number of allergies to the common used antiseptic.
Your input on this subject would be appreciated.
