Veterinary Numotizine Medicated Poultice is a poultice for temporary relief of muscle pain, swelling, stiffness, sprains, bruises or related conditions due to overexertion or exercise. Numotizine Cataplasm helps retain the body's own warmth in the area under treatment. Apply 1/4" thick poultice to skin and cover with suitable bandaging, or spread poultice on cloth first and then apply poultice-side down to skin. May be left on for up to 8-12 hours before removing and replacing with a new application, if desired. Numotizine Cataplasm contains guaiacol, beechwood creosote and methyl salicylate for comforting warmth.
