Rainfastness of pour on wormer

[early riser]

I need to treat my milkers with Eprizero pour on as soon as possible, however i have an outdoor collecting yard and its forecast rain pretty much every day for the next few weeks. Dont want to be pouring money down the drain, so does anybody have any idea about how rainfast these products are?

Thanks

Not very

Eprinex said it's weatherproof right away, on the packaging I saw last. I don't know about Eprizero, though.

Waiting time in the dry after treatment is usually printed in the info leaflet?

Rep at a meeting a couple of weeks ago said that it can be applied in any weather but that was the cydectin not eprizero. I would still rather it be dry for a hour or two to be on the safe side.

The main thing is they are dry when treated

Norbrook info online says Eprizero is weatherproof - rain, heat, everything - but there might be some tiny print somewhere that modifies.

With sheep pour on products I`ve phoned the manufacturer and asked for "technical" advice. Some of the advice is more believable than the rest though! Depends if you get a good person on the end of the phone....!

If It's for lungworm/ coughing in milkers, I will be interested to hear a report on the effectiveness of treatment.
During the summer treated ours twice with Eprizero about a month apart due to a widespread high level of coughing. Coughing did reduce after both treatments, but not cease.
Now housed but still got more coughing than I am happy with. Taken dung samples , no larvae found, Never saw any sick cows or distressed cows just too widespread coughing.

Treating for gut worms rather than lungworm

IBR?

I treated some heifers with cydectin 3 weeks tomorrow, forecast was good but we had a heavy shower about an hour later. Some are still coughing, I was wondering if the wormer had worked, any ideas?
No snotty noses so don’t think it’s ibr
