Zoetis Home / Products / Startect®
Startect is a short-acting broad spectrum combination sheep drench that kills the most damaging worms, including those that are resistant to existing drenches.
Startect has been purposely released in combination.
It contains a completely new active, derquantel (10 mg/mL). This is the first active from the new SI (spiroindole) class of anthelmintics. Startect combines derquantel with the powerful ML abamectin (1 mg/mL).
Startect is the newest class of sheep drench and the only one to be released in combination for improved sustainability by managing resistance better1.

Startect treats and controls of a broad range of susceptible adult and immature gastrointestinal nematodes of sheep, including those resistant to levamisole, benzimidazoles, macrocyclic lactones and closantel.
Startect is effective against adult and immature (L4) stages of sensitive strains of the following internal parasites, including those resistant to levamisole (LEV), benzimidazoles (BZ), macrocyclic lactones (ML) and closantel (CLOS):
Barber’s pole worm Haemonchus contortus; Stomach hair worm Trichostrongylus axei; Small brown stomach worm Teladorsagia (Ostertagia) circumcincta including inhibited (L4) stages, T. trifurcata; Black scour worm Trichostrongylus colubriformis, T. vitrinus; Small intestinal worm Cooperia curticei, C. oncophora, C. surnabada; Thin-necked intestinal worm Nematodirus spathiger*; Intestinal threadworm Strongyloides papillosus; Large bowel worm Oesophagostomum venulosum*; Large mouthed bowel worm Chabertia ovina*; Whipworm Trichuris ovis*; Lungworm Dictyocaulus filaria. (* adults only).
Startect was demonstrated to be effective against multi-resistant strains of Haemonchus contortus (LEV, BZ, ML and CLOS) and Teladorsagia circumcincta and Trichostrongylus colubriformis (both LEV, BZ and ML).
Startect is the newest addition to the Zoetis sheep health portfolio that also includes Glanvac®, Eryvac®, Gudair® and Scabiguard®.

Animals in excess of 75 kg to be dosed at 1 mL per 5 kg.
A representative sample of animals should be weighed before treatment.
Dose the mob to the heaviest animal by liveweight in each group (ewes, wethers, rams, lambs). Do not underdose.
Where there is a large variation in size within the group, dose rate should be based on the label directions for each weight range. Drafting into two or more lines may be appropriate, to avoid excessive overdosing.
Storage Recommendations
Store below 30°C (room temperature). Do not expose to temperatures below 0°C. Discard product that separates or contains sediment following exposure to temperatures below 0°C. Protect from direct sunlight.

Milk Withhold: Do not use in female sheep which are producing or may in the future produce milk or milk products for human consumption.
