How Do I Get Rid Of Heartworms In My Dog?

I know about revelotion
i do give my dog that now and then, but recently i found out at my dog’s annual check-up that he has heart worms, the vet said its a few, but to give him revelotion 1nce a month. my dog doesnt show any symptoms yet.
If you know any medicine that could kill the worms quicker i would really apreciate it.
