Worming is always a hot topic amongst horse owners

We are very aware that it was once strongly instilled amongst horse owners to give an Equest Pramox to all horses in winter. Unfortunately, we have since realised that this practice is wrong and leads to problems with wormer resistance. 𝗡𝗢𝗪 is the time to change and adopt a new approach.
𝗛𝗲𝗿𝗲 𝗶𝘀 𝘄𝗵𝘆:
🐛 Moxidectin (in Equest and Equest Pramox) is the only drug effective against encysted redworm and should not be overused
🐛 Praziquantel (in Equest Pramox) is one of only two drugs effective against tapeworm and so should also not be overused
🐛 If worms develop too much resistance to moxidectin and praziquantel, we will struggle to treat severe worm burdens in horses in the future (youngsters will be most affected, before developing a good immunity to worms)
🐛 Cases of resistance to both of the above drugs have already been reported
🐛 There are no new wormers on the horizon, so we must preserve the efficacy of the few we have
🐛 Many horses do not actually have a large encysted redworm burden over winter (e.g. horses between the ages 5-15 with consistently low WECs and good pasture management) and therefore do not require moxidectin
🐛 Only around 1 in 4 horses in the UK have a tapeworm burden high enough to need treating, so most do not require praziquantel
🐛 Therefore, only a small proportion of horses actually require Equest Pramox. Often, a different wormer is more appropriate, or for low risk horses with a negative tapeworm test, no wormer is required at all
🐛 Wormers can have a negative effect on the horse's gut health
🐛 Wormers are excreted in faeces, contaminating the environment - these chemicals are toxic to aquatic life and insects, such as dung beetles
