Yes, you can get them from your vet. I have used them a few times on my horse as he will not take antibiotics by mouth. You need to be shown how to do it and it is something that needs to be done very carefully. You can inject in the neck or in the rump. However, the first time you do it the horse doesn't really notice it very much but on consecutive days I found my horse was getting more and more wound up and very apprehensive - to the point that it was making me nervous and anxious. They are very much more expensive than the oral powders but I've no idea how much they cost these days.
You can, of course, buy antibiotics in the form of a paste, just like a wormer, if you can't put them in food.
Hope this helps.
Cant remember cost, Toffee had a 5 day course once, I had to inject into her chest on consecutive sides, she got more and more wound up. I doubt you can get them without prescription and dont forget the charge for the needles (good ole vet)
You can get Noradine as a paste, in a tube like a wormer, all ready to squirt down ned's throat. Be warned though, they are almost 4 times as expensive as the powder sachets. My vets charge £5 for a sachet, £18 for the tube. You can get a large empty (and needle-less) syringe from your vet and try making the powder up into a wet paste with eg apple sauce or baby foods but getting the mixture right, getting it into the syringe without it pouring out of the end, getting it into the horse when it clogs the syringe up all the time, you'll probably waste more than you get down him so you might find the tubes more economical overall.
Injectables are cheaper than oral drugs but you need to be confident and competent to inject your horse. As peviously said, many horses get very needle shy if on ABs for more than 4 days. I suggest making up a syringe with the powders or watr. Our powders and tubes are cheaper than BOF's vets but the paste is defintely 3 or more times the cost. We have one paste at £15 but have recently switched to a brand at £11.
Box of frogs - yes I have had the large needleless syringe thing for the last few times (accident prone horse....)
I have had to inject a couple of times too in the past and he really doesn't care in the slightest, so thought this might be the way forwards. He hates the syringe, and it is hard to get right and he backs away head in air as soon as he sees me coming, whereas he couldn't give two figs about a needle.
Will ask the vet. At his age, 30, I will stand the expense.
my horse has been on injectable antib's since nov everyday, i have found doing it quick makes it less of a chore for them and switching sides each day, i always give him atreat after as well and still i can injected him everyday without a headcoller or anything to restrain him
