I'm sorry your post was not answered sooner. The only immediate thing that I know to do is give him a bath in the blue Dawn dishwashing detergent. I'm sure that will probably also remove any flea prevention on him. I would suggest that you call the vets office in the morning and explain the situation, tell them you bathed him in Dawn and ask what prevention you can use that will keep this from happening again.
I hope this is helpful to you. I realize how late at night it is and you've probably tried another route. Good luck and I will be interested to know what prevention your vet suggests that you should use now.
