There's a full pour on dose on this page:

I thought his BlackSheepCardigan's input was pretty interesting on the same page about mass die offs:
"You cannot use injectable ivermectin in water. It's in a solution of glycol and does not dissolve in water. It also doesn't work super well on chicken internal worms. Great for lice and mites.
There is no such thing as 5% ivermectin unless you found it specially compounded somewhere. Ivomec pour-on is 0.5% ivermectin, which I guess is what's being referred to, but do not go looking for (and if you find it do not buy) 5% ivermectin.
Honestly, I do not know why Wazine is considered a good first wormer except that maybe it's so easily available and says chicken on the front. Piperazine has a very long withdrawal time and can produce nasty neurological side effects if humans or mammals ingest too much. Not something you want to keep under your kitchen sink, for sure.
You can use albendazole, 10-20 mg/kg (between a quarter and a half a ml per five pounds if you buy brand-name Valbazen), as a sole wormer. No need to use wazine first and it's safe for humans and other animals if they accidentally ingest it.
You can use fenbendazole, 10-20 mg/kg (between a tenth and a fifth of a ml per five pounds if you buy brand-name Safeguard goat) as a sole wormer.
You can use pyrantel pamoate, 10-20 mg/kg (get the dog liquid, which is marketed as Strongid, Nemex, and a bunch of others, and use between 1x and 2x the dog dose) as a first wormer; it removes roundworms only and is very gentle. Follow up with one of the others.
I don't know how true the theory of harmful die-off is, to be honest. It happens in heartworm in dogs when the arsenic treatment is given - that's real - but gut worms don't behave the same way. When Merial researches ivermectin to see if it works on cows they don't gently worm with something first. They stuff the cows with a huge worm load and then blast them with ivermectin. The cows don't die, they just get better. When you look at the research establishing the dosage of the drugs above, they're not using Wazine first. They just dose the birds and expect them to do well. None of the wormers on the market today actually kill worms; they paralyze them or interfere with their metabolism and the worms die off from starvation and paralysis. So no wormer is going to produce the instantaneous and massive die-off that supposedly chokes digestion. I wouldn't worry too much about that, but if you want to be super safe start with pyrantel."
I guess if it were me I'd go a head and do it. Wazine is not that strong anyway and you need to get your guy better.
