As you may know, there are increasing levels of resistance to the active ingredients in horse wormers.

As there are currently no new active ingredients coming to market, it is vital that we act now to ensure that these products remain effective in the future.

For this reason, horse wormers should only be used when there is evidence of a worm burden, with consideration of the individual horse’s needs, as well as the other horses it may mix with and where other measures have been put in place to minimise the risk of exposure to worms.

At this time, we are not able to effectively gather all the required information to prescribe this product appropriately.

Therefore, we have decided that for the time being we will only sell these products where a veterinarian, who is in the position to make the best-informed decision, has prescribed the product for your horse.

You will just need to upload or send us the written prescription so that we can fulfil your order.

We appreciate that this may be frustrating, but this important precaution will help us to protect your horses and prevent resistance to horse wormers for years to come.
