Attention all itchy and back sore horses! There are 2 USEF rule changes!
1) Cetirizine (Zyrtec) is now an approved substance! No more itchy ponies at shows!
2) There are now two different recommended withdrawal times for methocarbamol. If it is the only drug being given they are recommending 12 hours before but if another drug is also being used Methocarbamol processing may be delayed and so a withdrawal time of 24 hours is recommended.
Happy showing!
