Why is Levamisole Banned?

Levamisole is the key ingredient in Fido’s worming tablet commonly used due to its effectiveness and competitive pricing. However its just a worming tablet, so why is it specifically named as a prohibited substance in the Greyhound Australia Rules?

Weight Loss Stimulant

Several online sources state that when broken down in a canine’s body it produces a stimulant called Aminorex. Further online research suggests that Aminorex is linked to a weight loss stimulant. In the drug world apparently Levamisole has also been used to pad out cocaine, a process called an adulterant, and linked to several deaths.

Fido's Closasole
Will swab positive

The QGBOTA contacted the manufacturer Mavlab Animal Health, and their Veterinarian Dr. Paul Ross, kindly advised that the company have kept in contact with the Racing Science Centre (RSC) in Queensland over the past several years about their Levamisole product.

Issues revolve around the fact that one of the activities, when levamisole is broken down in the canine body, the chemical changes to an amphetamine type compound, which can lead to a positive swab.

The QLD RSC has carried out research, and has determined that the substance can stay in the body for up to two weeks after dosing, and return a positive swab. Mavlab advises not to use the Closasole product for Racing Greyhounds.

Alternative ProductsFido's All Wormer Tablets

Dr. Paul Ross went onto announce that Mavlab have recently introduced an alternative wormer product to their range, which
may be better suited to the Greyhound Racing Industry. Fido’s All Wormer Tablets contain the active increment Fenbendazole and Praziquantel. This comes in packs of 100 and is competitively priced against similar worming tablets.¬†Online pricing ranges from $140-$160 per 100 tablets for this tablet. At the request of the QGBOTA, Garrards at Albion Park are making enquires to make this product available on their shelf.
