New to Previcox....showing? Update : you can use bute too?

The USEA rules state it cannot be given within 12 hours of competition. When does the time of the competition start? If I am scheduled 11:00am dressage and 2:45 CC on Sat then 2:00 stadium on Sun, he will get his Fri dose but can he get his Sat dose at 3pm because we will have 23 hours until we compete in the next phase.

It’s the time you are competing. So yes, if those are the rules (and make sure you know the permitted dosage) he can get his Sat dose Sat night after he is done competing on Saturday and 12 hours out from his next phase on Sunday. But you can always send an email to the USEF for clarification.

If you are using Equiox you should have no problem with dosage. However, if you are using Previcox i.e. for dogs, be very careful not to exceed the USEF permitted dose. Some dog pills are 250 mg and even cut in half will show as an overdose if your horse is tested. Over the past few years, a number of competitors have been penalized for violations of he D and M rules because their vet was not specific about the dosage.

I would definitely check with the USEF about this. I was under the impression that in eventing all phases are part of one competition.

The point behind the withdrawal time is so that your horse, if tested, would be below the maximum allowable level. If your horse is above the therapeutic level upon testing, it doesn’t matter if you gave the dose 2 hours or 2 weeks ago, positive is positive.

Definitely check with the USEF, as I have not evented in a very long time, In dressage, we are only selected for testing upon leaving the arena following a test, so I have definitely given a dose in the “middle” of a competition if i am more than 12 hours out from the next possible selection time.

I’d be super cautious with the previcox, as a split tablet may have an uneven distribution of the active ingredients.

nope. Not for USEF competitions…so she needs to look at 12 hours out from the time she is riding as you are tested right after a phase. Now FEI…different kettle of fish.

I will check the dose but I think he is on 25mg and the max allowable is 49mg/1000 pounds. I think it is a timing issue. If he is in his stall, has not competed in 6 hours and is not due to compete for another 20, would they still test him ? It is just no give within 12 hours of a competing. The question is when does that start/stop?

Not a worry for us! Lol

In my experience testing is always done immediately after a round so they definitely wouldn’t pop by 6 hours after say our dressage test. It’s way more likely that they would as you come out of the ring and follow you back to your stall etc. I’ve also never heard of anyone, anywhere, testing positive after feeding the allowed dose the night before (like say the usual gram or so of bute). I’d just continue to feed it in the dinner feed and not sweat it. In your example you would be fine to give the Friday night dose, and give your dose on Saturday at 3pm (or later if that’s how you normally do it). If the allowed dose is 49mg/1000 pounds it sounds like you are well below that at 25mg and shouldn’t run in to any problems with drug testing if you follow the rules. The rule is intended to stop people from doing all sorts of thing the morning of the show like say an injection of adequan etc, or at least that was how I understood it from the Townhall I attended at Bend Oregon.

12 hours out refers to your time in the ring, and it doesn’t i.e. 12 hours out from 11am Saturday and 12 hours out from 245 on Sunday

So are USEA rules different than USEF? I thought one NSAID (ie equinoxx or bute but not both) is OK to have in their system if its under the allowable level?

I guess my question is if you give the proper dosage (mg/kg) for an oral NSAID daily to your horse and get randomly selected, will you test positive for a banned substance? I was under the impression the answer is no.

Previcox is restricted, not banned. Restricted means dose and timing. Banned means it can’t be in their system. It may be that USEA rules are different. Is Previcox an NSAID? I don’t think it falls in that category as it is a COX-2 inhibitor.

Yes it is. Many NSAIDs are COX2 inhibitors.

So here is my question. If you have a horse that gets the correct dosage of equinoxx in their AM meal, will they test positive for the drug or is that allowed?

have one who’s on it, and I was not aware of any restrictions other than dosage. If its as simple as being 12 hours out, I can just swap him to getting it in his PM meal.

Seems to me they should be more worried about the excessive lunging, reasoning why there are sharps containers in the barns at show facilities, and other crap that goes on in the H/J world than an older horse who is a bit stiff needing some help. But alas, that’s just my opinion.

The rule is given within 12 hours of competition and no more than 49mg/1000 pounds. Vic get 56 mg. It appears he can get his daily dose if dosed when we are done competing on Sat (around 3pm) as we don’t compete again until 2:00 the next day with follows the 12 hour rule.

Rehashing this thread as I didn’t know you could give bute at a competition . I was just told 2 grams of bute was ok as a one time dose, maybe following the 12 hour rule.

I don’t know the bute amount. I would think it may depend on size of horse. And yes… there are issues with using two types of NSAID. So you cannot use both bute and previcox so most people do not switch if their horse lives on one.

USEA doesn’t make drug rules but is under the umbrella of USEF. So USEF is relevant until you are competing in FEI.

All of the regulations are here:

Bute can be given up to 2g/1000lb BW in a 24 hour period, but must be 12h out from competition. You can only give it for 5 consecutive days.

You cannot show after combining two or more NSAIDS-for example you cant give bute and Equioxx.

That all being said, those are recommendations. So it does not guarantee that if you give only 2g/d for 5 days that you will be below their limit.

I got drug tested in June, and they met me as I walked out of stadium. My horse is on daily Equioxx, at the recommended dosage and I give it at night as the wording in the D&M document is 12 hours out from “competing” not “competition”.

And you are giving the 56mg horse dose?

They are 57mg and yes. My horse is roughly 1200 lb, so it would be 1mg over at the mg/kg they state, but I am not about to cut those pills to try to remove 1/57 of it.

I do however, because he is on it long term, keep him on it for 14d, then off for 7d, then back on before a show.

This thread has me wondering why the USEF guidelines for bute are in accordance with the approved dosage (1-2 grams per 1,000 lbs of bodyweight daily). But with regard to equioxx/firocoxib they diverge from the approved oral dosage which is 57 mg for horses from 800-1,300 lbs daily.

It seems like this could put those with small horses in a really tough spot.
