So everyone - in Europe - you should be able to get any medication you want - with a prescription for that medication from a veterinarian. It might be more expensive - or they might take pity on you - and give you some tablets. There is no such thing as 'this medication is not available here' - with the exception of copper. If I was an aquarist in Europe - I would call a veterinarian - explain the situation - and say - I want to have medication in stock - in case of a problem - but before I use it - I will call for your approval. This also goes for praziquantel, etc. I would suggest - make a friend of a veterinarian
