View Full Version : Zithromax

Hi guys,

I know we have some Zithromax users on here. I just wondered what form you used, or what forms it comes in.

Desperate to get my Badger on it (and probably Cloud too), but need to know what to say to the vet who has never used it in buns before.

Thanks :D

Hi :wave:

Pickles, our French Lop has been suffering with pneumonia since November :shock: and after the 3 months of Baytil and Septrin the vet prescribed a 10 day course of Zithromax, which has done wonders for her :D

Becuase she is a big girl, weighing in at over 5Kg, she was on quite a high dose - 1.9ml twice a day, so we had to buy 3 x 15ml bottles which were about 15 each!

The bottles had a powder in them which we had to add water to and then shake, this then made a very thick syrup which we gave her on fenugreek crunchies as she hates having meds syringed - believe me after 4 months we have tried lots of ways!

My vets were really good and got in touch with a rabbit specialist who advised them about the dosage, perhaps you could suggest that to your vet.

Good luck and I really hope that it helps your bun(s) as much as it seems to have helped Pickles.

i would highly reccomend zithromax as it cured my headtilt bunny after numerous other drugs failed. We had the powder that you made into a liquid and my bunny took it fine with a syringe. They first got it for me through the chemist but then got their own supply. They were so impressed with it they now keep it in stock.

I couldn't find a definitive doasage, but this is the nearest I could find:

Dana Krempels gives the dosage as 20-30mg/kg once per day (see http://en.allexperts.com/q/Rabbits-703/2008/8/Zithromax-dosage.htm )

Medirabbit gives the dosage as 30-50mg/kg once per day (see azithromycin here: http://www.medirabbit.com/Safe_medication/Antibiotics/Safe_antibiotics.htm )

So perhaps start with 30mg/kg in the absence of any better info?

I live in the US., not the UK. I do not understand what the kg/mg is. I use a 1.0 ml medicine syringe. A thin skinny one. Not the fat ones. A full one is 1.0 cc right? The vet stated a 1.8 cc dosage for Sammy for the Azithromycin. That is almost 2 of these syringes full. Is that too much? Or is that normal for an 8 lb rabbit? The vet is a very good one & is highly recommended for any kind of exotic pet. Especially rabbits & birds. I trust his judgement but want to make sure I am getting the dosage right. Any help is appreciated

Mg/kg is milligrams of the active ingredient in the medication, given for every kilogram of the rabbits body weight. So with liquid medication like oral suspensions or injectable meds, there is the concentration of active ingredient, in this case azithromycin, measured in milligrams, in a milliliter of the liquid. So if you have an azithromycin suspension that is, let's say, 40mg/ml, then that would mean there is 40mg of the antibiotic in a ml of the suspension liquid. The vet determines the amount, or mg, of the medication that a rabbit needs per kg of body weight, and takes the amount of the concentration of the med in the bottle being used(mg/ml) and calculates the needed dose.

So to know if the dose you were given is correct or not, you would need to know the concentration(mg/ml) of the medication that you were given.

Something to also be aware of with azithromycin if your vet didn't discuss it, is that it can cause a loss of appetite in some instances. So it would be good to also be prepared to syringe feed your rabbit in case this happens, if this isn't already something you are doing.
