Hello Steve
How are you doing, I hope very well.
As you know, there is a global blockade of the active ingredient Ronidazole; according to the latest news we have, it will not be available until mid-2026.
As a consequence of this, many products are not available and will not be available for many months; here are some of the most commonly used ones:
Tollisan Kombi
Tollisan TKK
Pantex Roni 40 y 50
Pantex RoniPlus
Pantex Cocci Geel
Belgica de Weerd Belgaroni...
Almost daily, we receive inquiries from customers asking about the availability of these products.
For your convenience, here are some of the alternatives we currently have available; our stock is ample but is quickly running out; if you are a user of these products, I recommend you buy them before they run out.

Thanks for posting Buster. As you know I don’t treat for anything myself but I’m sure good information for those that do. Does seem a very long time before these products are going to be available again. I wouldn’t hold my breath on them being available again. Alternatives will be found that will become the normal products used.
Back just enjoying club racing for the time being.
Probably Metronidazole (Flagl) for canker. The tablets are very good when you only want to treat certain birds. They seem to be safe to use too, for racing or breeding.
I had a few, but they went out of date about 10 years ago
