Do you have another shot if it recurs in the night? If I recall Banamine gets you about six hours relief if symptoms are going to return.
Yes, we have a bottle. This last time, we got Flunixamine instead of Banamine - I think it's the about same thing but will look it up on line. The insert says once daily, onset within two hours, peak response occurs between 12-16 hours and duration is 24-36 hours. That is more potent than Banamine.
I think we are okay until morning but I'll be out a couple times at least to check on my boy.
