1000 tablets for £41 on prescription, so no need to panic too much, if your vet charges much more it would be worth paying for a prescription if treatment is long term. Sorry wrong link this should be right, £30 for 500 http://www.vetscriptions.co.uk/pred5.html
Thankyou thats encouraging - especially the first post, but also thanks to the second ..... I have 2 tubs of 2000 tablets each so I reckon about £160 - £200. Just about manageable as long as it doesnt turn out to be long term at that dosage. Thanks tons xxx
