Merck Animal Health Launches Safe-Guard® AquaSol

Highly Effective Dewormer Approved by FDA for use in Poultry

MADISON, N.J., January 14, 2016 – Merck Animal Health (known as MSD Animal Health outside of the United States and Canada) today announced the introduction of Safe-Guard® AquaSol (fenbendazole oral suspension) for use in U.S. poultry operations. Safe-Guard AquaSol is indicated for the treatment and control of adult Ascaridia galli in broiler chickens and replacement chickens intended to become breeding chickens, as well as for the treatment and control of adult A.galli and Heterakis gallinarum in breeding chickens.

“Managing gastrointestinal health properly results in better overall performance – uniformity, productivity and profitability,” said Ivan Alvarado, D.V.M., Director, Poultry Technical Services, Merck Animal Health. “Effective management also helps to minimize the economic impact that comes as a result of production losses, which is a priority for all of our customers.

“Safe-Guard products have a long history of proven results and we are excited to bring a new poultry formulation to the industry – one that provides a unique uniform treatment for the entire flock and has been approved by the FDA for use in chickens.”

Safe-Guard AquaSol is produced with an innovative wet-milling technology, which produces a highly stable suspension that can be conveniently administered through drinking water for a short, five consecutive-day treatment period.1 The product’s smaller particle sizes help to prevent sedimentation and clogged pipes, filters or nipple drinkers.1 There is no pre-slaughter withdrawal period when used according to the product label.

Safe-Guard AquaSol is available in 1 liter and 1 gallon presentations. For more information about this product, contact your Merck Animal Health sales representative.

Safety Information:
No withdrawal period is required when used according to the label. Do not use the drug in laying hens and replacement chickens intended to become laying hens. Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism.
