HI Everyone, I received this letter from a horse friend of mine via email. Anyone else get it? Is there any truth to it?  Just curious as to what you all have experienced with Equimax. 
Thank you,
Rita

Letter:

Hi Everyone:

Dad I spent a couple of hours with Tom and Martha Anne Shires yesterday regarding the details of losing a young healthly Thoroughbred horse that was just ready to go to the race track. They wormed with with a NEW wormer by Pfizer called Equimax.

Equimax contains:

1.87% Invermectin
14.03 % Praziquantel (this is for tape worms)

There regular wormer is Equalvan Gold which contains:

!.55% Invermectin
7.74% Praziquantel

Equalan Duo contains also:
!.55% Invermectin
7.75% Praziquantel

From this you can see the Praziquantel in Equimax is double the amount than the other two wormers.

After giving the horse the wormer it developed severe colic, then a hole was burnt in the horses small intestine. The horse was passing parts of the small intestine in his manure, then blood showed in his urine and his kidneys shut down. Peritonitis set in and the horse didn’t have a chance. He died in 7 days. The vet says the Praziquantel was too strong at 14.03 % and killed this young horse.

The Equimax was purchased at the feed store in Addison Dixie and Egan. Tom and Martha Anne went to Ritchie Feed and Seed store in Brockville and talked to Andrea the horse expert. Andrea said she was not carrying the product as it was too NEW. Andrea called her representative and she obtain the telephone number of the vet who made Equimax. He refused to give information as he thought a class action law suit might occur.

Shires have had their horses fecal samples check when they used Equalvan Gold and their samples where clear of parasites. So why has Pfizer double the dose of Praziquantel For tape worms?

I did find a company in the US that has pulled Equimax from there product line saying it was no longer available.

Please pass this warning to your horse friends and if anyone has had an experience with this product please let me know.


Sincerely Ruth Freeman

Tapeworms don't show up in fecal egg counts.  Even though I get clear fecal egg counts using just a daily dewormer, the lab told me I should still be pasting for tape worms.  I haven't yet, but am thinking about it...

It's not a new product. I have been using it for 5 years at least. I prefer it to Zimectrin Gold, in fact.

These bogus chain letters are unfortunate.

Just wormed my boarder's horse with Equimax on Saturday.  She's still alive.   Don't they test these products at hundreds of times the suggested dosage?   I can't see where double the strength would cause such a serious problem - there must have been something else going on.

I've used equimax and never had a problem. My sister on the other hand, lost her 2 year old colt this spring. She wormed him - he was on an every 8 week rotation and she used equimax for the first time. He coliced and died. The colic was so bad that part of his intestines came out - something that I have NEVER seen. There was nothing the vet could do.

food affects every individual differently... so do wormers im sure....

my cat is allergic to red dye... if she eats it she goes into a coliced like state.... doesnt mean that your cat will die if it eats iams or cat chow....


im sure that this wormer has caused the death of some horse but im sure all of them have along with feed and supplements....

its a chance you take trying new products that it MAY have something in it that may not agree with any animal and or person you use it on

I am not sure if it makes a difference or not but I always worm my horses after they have eating so they are getting it on a full stomach. Just makes sense to me some how.

I could have sworn I read that wormer is NOT effective unless it's on an empty stomach.  Because of reading that, I always time my worming (when I used to paste, I don't anymore) to be an hour or so after they have finished their morning meal with hours before their next meal.  I read that hay in particular lessens the effectiveness.
