Do not use Noromectin wormer in horses known to be hypersensitive to the active ingredient or to any other ingredients. 

Do not use in dogs or cats as severe adverse reactions may occur.

Special warnings for each target species 

The veterinary medicinal product has been formulated specifically for use in horses only. Dogs and cats may be adversely affected by the concentration of ivermectin in the veterinary medicinal product if they are allowed to ingest spilled past or have access to used syringes.

As with all anthelmintics, a veterinary surgeon should establish appropriate dosing programmes and stock management to achieve adequate parasite control and reduce the likelihood of anthelmintic resistance developing.

Use during pregnancy, lactation or lay 

The veterinary medicinal product can be administered at any stage of pregnancy. 

Ivermectin passes readily into milk. When administering to lactating females, residues of ivermectin could be present in the maternal milk. No studies have been reported on the effect of ingestion of milk on the development of newborn foals.

Do not use in mares producing milk for human consumption. 

Amounts to be administered and administration route 

The veterinary medicinal product is administered orally at a single dose rate of 200 μg/kg of bodyweight. One syringe division of paste should be administered per 100 kg bodyweight (based on the recommended dosage of 200 μg/kg (0.2 mg/kg). Each syringe delivers 140 mg ivermectin, sufficient to treat 700 kg of bodyweight. Horses weight should be accurately determined for the correct use of the paste. The animal's mouth should be free from food to ensure swallowing. 

The tip of the syringe barrel should be inserted at the interdental space (the gap between the front and back teeth). Immediately elevate the horse's head for a few seconds to ensure swallowing. Do not use the same syringe to treat more than one animal unless horses are running together or in direct contact with each other on the same premises. 

For best results all horses in a yard or grazing together should be included in a regular parasite control programme, with particular attention being paid to mares, foals and yearlings, and treated at the same time. Foals should be treated initially at 6-8 weeks of age and routine treatment repeated as appropriate. 

Retreatment should be done according to the epidemiological situation, but not less than 30 days intervals.

Withdrawal period(s) 

Edible tissues: 34 days. 

Not permitted in mares producing milk for human consumption. 

Active substance: Invermectin 1.87% w/w (18.7 mg/g)

Legal Category: POM-VPS
