Our 5.5 lbs Yorkie took well to Revolution for flea control. It's topical - you just crack open the plastic vial and pour it in between the shoulder blades on the back. I only needed one dose and you can bathe them anytime after a day.
Maybe you can ask whether your vet can prescribe this one if she's vomiting on the one you tried?
