Dosage & Administration

Levafas Diamond should be administered as an oral drench. Dosing must be carried out accurately using a suitable gun system, at a rate of 7.5 mg levamisole hydrochloride and 15 mg oxyclozanide per kg bodyweight.

To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of the dosing device should be checked. Animals should be dosed according to their individual weight, and not dosed as per the heaviest animal in the group, otherwise signs of overdose may occur.

Thoroughly shake the container well before use to ensure that the two active substances are homogeneously resuspended and therefore the animals receive the correct dose.

Do not mix with other products.

Double strength: Follow dosage instructions carefully

Cattle: 2.5 ml per 10 kg bodyweight

Sheep: 0.5 ml per 2 kg bodyweight

Sheep over 60 kg should be given a further 1 ml per additional 4 kg bodyweight.


  • Animals must not be slaughtered for human consumption during treatment.
  • Cattle and sheep may be slaughtered for human consumption only after 5 days from the last treatment.
  • Must not be used in cattle and sheep producing milk for human consumption.
