Composition Abamectin 3.7 mg/g, praziquantel 46.2 mg/g. Promectin Plus Allwormer Paste for Horses is a Palatable oatmeal flavoured oral paste. Abamectin has been demonstrated to be safe when used at twice the recommended dose in foals, pregnant mares and breeding stallions, and up to five times the recommended dose in adults. Praziquantel is an isoquinoline pyrazine which is readily absorbed from the gastrointestinal tract and excreted in the bile and urine. It has an extremely high activity against all species of tapeworms. Praziquantel has been shown to have a wide safety margin. Use as an efficient broad spectrum wormer for the treatment of internal parasites including tapeworms Anoplocephala perfoliata, A. magna, and Paranoplocephala mammillana (adult and immature, heads and segments); large strongyles Strongylus vulgaris (adults and arterial larval stages), S. edentatus (adults and tissue stages), S. equinus (adults) and Triodontophorus sp. (adults); small strongyles including benzimidazole resistant strains (adult and immature) Cyathostomum sp., Cylicocylus sp., Cylicostephanus sp., Cylicodontophorus sp., and Gyalocephalus sp.; pinworm Oxyuris equi (adult and immature); ascarids Parascaris equorum (adult and immature); hairworm Trichostrongylus axei (adult); large mouthed stomach worm Habronema muscae (adult); neck threadworm Onchocerca sp. (microfilariae); bots Gasterophilus sp. (oral and gastric stages); lungworm Dictyocaulus arnfieldi (adult and immature); and intestinal threadworm Strongyloides westeri (adult). Also effectively controls skin lesions caused by Habronema and Draschia sp., and cutaneous larvae (summer sores) and microfilariae of Onchocerca sp. (cutaneous onchocerciasis). Withholding Periods Horses: 28 days. Dosage and Administration 1 mL/20 kg bodyweight (5.4 g/100 kg bodyweight) administered directly into the mouth or mixed with feed. All horses should be included in a regular parasite program, with particular attention paid to mares, foals and yearlings. Because re-infection is common, treatment must be repeated routinely for effective control. Consult a veterinarian for a control program to meet your needs; however, in general treatment should be repeated every six to eight weeks for effective worm control.
