Is regumate a banned substance?

[Confuzzled]

For competition purposes (I will be show jumping) is regumate a banned substance or is it allowed? At the moment my mare is on regumate to try and control her hormones as she is a complete nightmare in the summer months else but I need to know if you are allowed to compete under BSJA rules on it? Anyone who knows or knows wher to find out it would be appreciated! I may try ringing the BSJA if no-one knows
Thanks for your help!

I would ring up, but regumate is used by my father with his horse to help her hold her foal during pregnancy. I should think it should be safe, but deffo phone.

Rules changed recently to allow it in FEI competition.

I know BD and BE have followed suit so would assume that the BSJA will have as well. Probably still best to check though.

Ok, thank you, i will ring up and double check but fingers crossed sounds like we will be ok!
