The veterinary practice was also compounding and distributing an unapproved new animal drug, GM 100. The practice is not taking appropriate measures to guard against illegal drug residues. It prescribed and dispensed sulfadimethoxine 12.5% oral solution for intravenous use to treat mastitis in lactating dairy cattle, an extralabel use which is prohibited.
