experience with promeris flea treatment

[frankofile]

Following on from last weekends canter about hairloss in cats, for which I am very grateful for everyones advice, my vet has changed our flea regime from Frontline to Promeris, supposedly it lasts 6 weeks rather than 4 with Frontline. I have managed to treat 3 out of my 4 cats. 2 of them have developed a bald patch on their neck where the lotion has touched, and Minnie is scratching more than ever. Is this a very strong treatment to which some cats are sensitive. Has anyone out there had any experience of it?

This is from a Pug forum in the States, which was posted on one of my dog groups recently:
this is a very important message to my family & friends who have
dogs-cats--and to alert you to the hazard of using a new Flea & Tick
Preventative called ProMeris http://www.promeris .com/consumer/ .
This is a new product designed to be a more effective product than other
flea/tick treatments that was just released this year. It is available thru a
vet and not currently on-line. I got ProMeris this week for my 7 dogs (6
Huskies & 1 Golden-Airedale) , and the results were debilitating for nearly all
of them-including me. Since my incident this week, my vet has pulled it from
distribution and alerted the manufacturer, Fort Dodge .
Here are my results: Within less than 2 hours after applying, 4 of my dogs had
vomited from 2-4 times, 3 were disoriented and stumbling, 1 was dragging his
back leg, 1 was salivating. I had very similar symptoms like an allergic
reaction-my lips were swollen, eyes very red, mucous membranes such as eyes,
nose, and mouth were stinging. I was very disoriented-dizzy equilibrium and not
able to drive. To make this a short story-all 7 of my dogs were admitted to the
hospital for veterinarian care, and 3 of them remained for care, IV fluids and
observation for 24 hours. I was in the emergency room. I'm home now and so are
the dogs. We're all feeling much better. Vet bills were over $2,500 and Fort
Dodge is paying for these. Not only can the product cause this reaction, it has
a highly noxious odor that permeated the house and is just starting to dissipate
after 3 days.
Your dogs/cats might not have the same reaction, but given my experience-I
wanted to help you all become well-educated about the product.

A bit more light reading for you on Promeris.

I've never used Promeris so I can't comment.

If the spot-on has caused it, you should report that to the vet so they can make an adverse reaction notification to the drug company.
