Norbrook Laboratories Ltd was established more than 40 years ago and is, today, a leading, global pharmaceutical company. Our extensive research and development programmes have led to the creation of many revolutionary veterinary and animal healthcare products and medicines such as Procaine, Benzocaine, Flunixin, Ivermectin, Carprofen and Oxytetracycline. Our head office is based in Newry, Northern Ireland and we have manufacturing facilities in four continents: UK, Australia, Kenya and USA. We are proud to be the only British owned manufacturing company that is licensed by the United States Food and Drugs Administration to manufacture sterile injections for veterinary use outside of the USA and export them for sale in the USA. Alongside our wide range of products we have also recently developed the revolutionary Closamectin Pour On for the treatment of internal parasites, external parasites and liver fluke (both late immature and adult) - the only pour on product available in Europe.
