You are allowed to use generic chemicals (products not marketed as veterinary medicines) to treat your own animals. You must comply with fit for purpose requirements stated under regulation 7 of the ACVM (Exemptions and Prohibited Substances) Regulations 2011. In particular, you must manage any risks to animal welfare and make sure residues aren't in animal produce you sell for human or animal consumption.
