Elanco Cydectin Pour-On Cattle Parasiticide 1L — Moxidectin Weatherproof Topical with Purple Dye

Cydectin Pour-On is a weatherproof, ready-to-use moxidectin parasiticide for beef and dairy cattle that treats multiple internal and external parasites while requiring no milk or slaughter withdrawal.

Formulated by Elanco, Cydectin Pour-On (moxidectin) is a 1L topical treatment designed for broad parasite control in beef and dairy herds. It targets common adult internal parasites and many larval stages, and it also controls external pests such as horn flies, lice, cattle grubs, and mites. The purple dye helps you verify which animals have received treatment, and the formula is rain-resistant so it holds up in variable farm conditions. One bottle treats up to 40 head of cattle weighing as much as 550 lb each; follow label directions for accurate dosing by weight.

How does Cydectin Pour-On protect cattle from internal parasites?

Cydectin relies on the active ingredient moxidectin, a milbemycin-class compound, to reduce burdens of several adult worm species and many larval stages. It is intended to interrupt parasite life cycles on treated animals when used as directed. Always weigh animals and follow the product label for correct dose and timing to get expected results.

• Controls 13 species of adult internal parasites including brown stomach and lungworm
• Acts on many larval stages of gastrointestinal worms like barber pole nematodes
• Administered topically with dosing based on animal weight
• Label instructions provide timing and retreatment intervals

Will Cydectin Pour-On work in wet or changeable weather?

The formulation is designed to be weather-resistant so that rain shortly after application does not negate the treatment. The dye helps visually confirm application coverage even when conditions are less than ideal. For best results, apply according to label directions and avoid extreme runoff situations.

• Weatherproof formula maintains efficacy through rain or damp conditions
• Purple dye marks treated animals clearly for flock management
• Topical pour-on delivery reduces handling time per animal

Can I use Cydectin Pour-On on lactating or young cattle?

Cydectin Pour-On is labeled for use in cattle of all ages, including lactating dairy cows. The product carries zero milk withholding and zero slaughter withdrawal when used according to label instructions, simplifying herd management. However, always read the label for any regional or situational restrictions.

• Suitable for beef and dairy cattle, including lactating animals
• No milk withhold and no slaughter withdrawal per label directions
• Dosing instructions vary by weight—measure animals to ensure correct dose

How does Cydectin help with external pests like flies and lice?

Cydectin Pour-On also targets many common external parasites, providing a multi-purpose approach to herd pest control. Topical application distributes active ingredient along the animal’s hide to reach lice, mites, horn flies and grubs. Incorporate it into your overall parasite-management plan for seasonal control.

• Controls horn flies, lice, cattle grubs and mites
• Topical application spreads along the hide for external pest contact
• Useful as part of integrated pest management and rotational treatments

Who is this product for? Cydectin Pour-On is intended for cattle producers and herd managers looking for a single, practical topical product to address a wide range of internal and external parasites. It suits operations that need a weatherproof treatment, visible dosing confirmation, and flexible use across ages and lactation stages. Always consult the product label for complete dosing, safety, and usage instructions, and keep this product out of reach of children.
