Overview
Cydectin Oral Sheep Drench (moxidectin 0.1%) by Boehringer Ingelheim is an oral drench dewormer for sheep providing broad-spectrum control of gastrointestinal roundworms, including barber pole worm (Haemonchus contortus) — the most economically devastating internal parasite in sheep operations. Moxidectin is a milbemycin-class macrocyclic lactone that is closely related to the avermectins (ivermectin, doramectin) but has a distinct chemical structure that results in a longer half-life and higher lipophilicity — allowing it to persist in tissues longer and providing an extended duration of parasite control compared to ivermectin. Critically, moxidectin retains efficacy against some ivermectin-resistant strains of Haemonchus contortus — making Cydectin a valuable tool in sheep operations where ivermectin resistance has been confirmed or is suspected. Administered by oral drench at the labeled dose based on body weight. The 1000 mL bottle provides a high-volume supply for flock-level deworming programs.

Best For
- Flock-level deworming programs targeting barber pole worm and GI nematodes in sheep
- Operations where ivermectin resistance has been confirmed or suspected in the flock

Follow all label directions for dosage based on body weight. Consult your veterinarian for guidance on sheep parasite management, FAMACHA scoring, targeted selective treatment (TST) programs, fecal egg count monitoring, and dewormer resistance testing to preserve moxidectin efficacy in your flock.
