I have a little one only a few days old I've been using an eye dropper to feed him long story short he's aspirating and struggling when he gets these fits. What I am here to ask is can I use Fish Mox Forte as a substitute it's 500mg and in it's abbreviation description Here is the description: Fish Mox Forte (amoxicillin) exerts a broad range anti-bacterial action on both gram-positive and some gram-negative bacteria. It is generally more effective in gram-positive infections. http://www.californiapetpharmacy.com...BYYhoC2eTw_wcB. Here is a link to the product.
