Hello. I can't tell you whether or not you got Frontline on you I'm afraid, but you could settle the question of how much you need to worry by calling 111, the UK lo-priority nedical advice line, or your GP or pharmacyst. You could say, 'it was definitely no more than X amount,' and ask if you need to do anything differently. I suspect that the answer may be no, but I am not qualified to give medical advice to humans.
