My horse was on it for over two years with no issues. When we started him on it we loaded it. I think it was one 57 mg. tablet twice a day for seven days and then one tablet a day. My gelding had mild ringbone so he wasn't lame so the effects were subtle. I would think that 2 weeks would be fair.

Previcox does have a long half life in horses, so at once a day it does build up in thier system over time. Some horses can handle that, but to be safe many vets recommend decreasing the dose after 10-14 days. The "ideal" time frame would be to give a dose every 36hours, but that can get confusing. Every other day works well for most horses, or going with a half dose daily (or a half dose one day and a full dose the next) are other alternatives.
is to split your pill and give 1/2 am and 1/2 pm that way it's easier to drop down your dosages. We've been on it since Monday and will ride tonight for the first time. Not holding out but so much hope although I have seen it work wonders.
Just a little warning. My horse developed full-blown right dorsal colitis after 4 days on bute. 4 years later after a full recovery I put him on Previcox for some hock issues. Previcox was supposed to be our savior. After 3 months on it, the colitis returned.
So don't think that Previcox is without side effects. Granted, most horses will be fine. But still, please watch your horse closely.
