Is there anything I can do to help my kitten who has worms?

Its 11:36 pm and I can't take the kitten to the vet til' tomorrow. I found out he had worms tonight when I looked in his stool I saw worms. And his belly isn't the normal size, he has a potbelly. Is there anything to give him to drink or eat that will maybe kinda irritate the worm or kill it while its inside of him so he can poop it out? I thought about vinegar but I don't think you should give that to a kitten, he is actually like 8 or 9 months old but thats still a kitten.
