A summary of my understanding of the requirements of the Vetinary Medicines Diretorate 2006(VMD2006 or VMD)... after enquiries about importing meds that are legal in the ec but not in the UK.., eg metronidazole, praziquantel levasimol etc.
It is illegal to own, use, or administer ( obtain, supply, give away) ANY restricted medication unless under the direct supervision of a vet or "qualified person"...such a person will be a specialist such as a fish health advisor on a fish farm etc...
It is also illegal to use a prescribed, restricted or over the counter medication on any animal it is not approved or perscribed for. Using a pig wormer on fish is illegal, using metro prescribed for sheep on fish is illegal... and the penalties are steep. With the exception of vetinary supervision on non food animals where a degree of freedom in the choice of meds is allowed.
Approval for use in any other country is not an acceptable argument, it must be approved in the UK under the VMD, even if it is legal in almost every country in the EC it must still be approved for use on the specified animals in the UK.
VMD lists such medications & places them in several categories... for us it falls into 2, over the counter medications (ie I can buy it in a shop) & those requiring "access" either as a vet or qualified person ( ie perscription meds etc.) . For our purposes a med certifed under the "small animals exemption scheme" such as flubenol 15 is concidered an over the counter medication...ie it is a perscription medication but the specific packaging & approved use are exempt from the requirement to be used under supervision.
As far as advice goes, I would take the view that reccomending a particular over the counter med for treatment is OK, as long as the med is approved for that animal, so advising octozin for HITH/spiro is OK as that is what it is marketed for. Suggesting someone gets hold of a product not approved but known to be effective ( eg pig wormer) & use it for fish is in breach of the regulations. Should the octozin prove ineffective (staying with the above example) then advising MEtro would not be a breach, as long as you also suggested seeing a vet for the medication, rather than picking some up next time you are in Spain for eg.
Please also be aware that they are persuing these regulations and are determined to prosecute those found in contravention of the requirements, not just the players but the users too.
