    Product was fine, shipping was terrible

    By Amber on Oct 19, 2021

    Product sat in Boise for 5 days, so ended up having to get antibiotics elsewhere.

    Uniprim for gutteral pouch infection

    By horselady on Aug 5, 2020

    Used this product previously for 35 days and the horse was significantly better, but there was still some nasal drainage. I purchased the 2,000 gram tub and have started the horse on it again. My vet suggested using the entire tub if necessary to totally eliminate the infection. I hope it won't take that long, but this type of infection is apparently stubborn and hard to eliminate. I see progress after about 2 weeks, but will continue with treatment until I am sure it's gone.
