Depending if it's injections or topical is dependant on wich kind you buy. Using either types in it's opposite application method can be deadly.

This is the kind I use. It's the one you apply at the back of the neck. Last time I actually dropped the drops in their ears insted, bothered them a little but was much faster then sorting through the fur of each of my rabbits.
On a baby (less then 2 pounds) I use 2 drops.
On a 2.5 to 5lbs I do 4 drops.
On a bigger rabbit, I do 6 drops
No more then this for safety. You should see changes within a couple days already, but if after a week nothing changed you could do another dosage, but wait at least a week.
I've not had any of my rabbits get sick from this dosage. As for what Amberrae said about vienna marked it hasn't happened in my case. I'm a fan of blue eyes, so even if it's a DQ on lionheads I have 4 vienna marked rabbits and planning for more.
This will protect your bun from many nasty things, so it's very worth it. Just keep the bottle in the fridge between use. To maintain treatment on your bun, just do this every 6 months and you'll never have this issue ever again. You can even use it on your cat or dog with proportionnal dosage to their weight if you have them! <br /><br /> -- Sat May 20, 2017 11:34 pm -- <br /><br /> Also I didn't see any fleas in your pictures, nor the tell tale sign of the ç shaped poo they cause. All I saw were flakes and that's cause by skin mites. Doesn't mather either way though, the ivermectin will deal with all of them regardless mwahahaha :twisted:
