Has anyone else had problems with Sentry pro XFC?

DO NOT USE SENTRY PRO XFC on your dogs!!! My poor little beagle had a horrible reaction to this flea drop medication. I normally buy Frontline, but I wanted to try something new and less expensive. So, I bought this product and put it on my dog as directed. Just a few hours later my Daisy started acting strange by scratching and licking excessively. Then she started foaming at the mouth and she then got sick and started vomiting. I was totally freaked out, so I called the number on the back of the box and talked to the professional. They said that it is just an allergic reaction from the product getting in her mouth, not to worry that it was just the medicine bothering her. She told me not to worry that it wasn't dangerous and to wash my dog a couple of times with dish soap to get the medicine off. I hoped that this helped, but it didn't. I am really worried about my dog! I noticed that I am not the only one with a problem with SENTRYPRO XFC. Maybe there needs to be a recall on this!
