Dosage & Administration

Noromectin 1.87% Oral Paste for Horses is administered orally at a single dose rate of 200 ?g/kg of bodyweight. One syringe division of paste should be administered per 100kg bodyweight (based on the recommended dosage of 200 ?g/kg). Each syringe delivers 140mg ivermectin, sufficient to treat 700kg of bodyweight. The tip of the syringe barrel should be inserted at the interdental space (the gap between the front and back teeth). The horse’s head should be raised
for a few seconds after dosing.

Horses’ weight should be accurately determined for the correct use of the paste. The animal’s mouth should be free of food to ensure swallowing.

For best results all horses in a yard or grazing together should be included in a regular parasite control programme and treated at the same time.

All horses should be included in a regular parasite control programme, with particular attention being paid to mares, foals and yearlings. Foals should be treated initially at 6-8 weeks of age and routine treatment repeated as appropriate. Retreatment should be carried out according to the epidemiological situation, but not less than at a 30 day interval.

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.

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.

Withdrawal Period

Animals must not be slaughtered for human consumption during treatment. Horses must not be treated within 34 days of slaughter for human consumption. Do not use in mares producing milk for human consumption.

Contraindictions, Warnings Etc

Noromectin 1.87% Oral Paste for Horses has been formulated 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 paste or ave access to used syringes. Avermectins may not be well tolerated in all non-target species (cases of intolerance with fatal outcome are reported in dogs, especially Collies, Old English Sheepdogs and related breeds or crosses, and also in

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

This is a unidose product which should be disposed of after use.

Frequent and repeated use may lead to the development of resistance.

Some horses have experienced reactions involving cutaneous swelling and itching shortly after treatment. In most of these cases, the horses have been diagnosed as carrying heavy infections of Onchocerca microfilariae, and it is assumed the reactions are a result of the microfilariae dying in large numbers. Although the signs will resolve spontaneously in a few days, symptomatic treatment may be advisable. Consult your veterinary surgeon should these signs persist.

Horses of all ages, including young foals, pregnant mares and breeding stallions have been treated with no adverse effects on their health and fertility. 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, therefore it would be prudent not to feed very young animals with milk obtained from the mother.

Mild transitory signs (slowed pupillary light response and depression) have been seen at a higher dose of 1.8mg/kg (9 times the recommended dose level). Other signs seen at higher doses include mydriasis, ataxia, tremors, stupor, coma and death. The less severe signs have been transitory.

Although no antidote has been identified, symptomatic therapy may be beneficial.
