Allverm 4% Oral Suspension for Sheep is a pink-coloured aqueous suspension containing 4% w/v ricobendazole, (albendazole oxide), with 2.88% w/v cobalt sulphate (hydrated) and 0.30% w/v sodium selenate (hydrated) as excipients for oral administration.


For the control of adult and other larval stages of benzimidazole-sensitive gastro-intestinal roundworms, tapeworms and lungworms, and for the control of adult liver fluke and the treatment of chronic, but not acute fasciolosis in sheep. The product is ovicidal. Allverm also aids in the prevention of cobalt and selenium deficiency.

Dosage and administration

Allverm 4% should be administered orally using standard drenching equipment. Assess bodyweight as accurately as possible before determining the dose volume. Use the dose volume appropriate to the heaviest animals when treating on a group basis.
Worm Dose
Allverm 4% is administered at a dosage of 1 ml per 8 kg bodyweight. At this rate the dosages are 5 mg Ricobendazole/kg, 0.75 mg Cobalt/kg and 0.08 mg Selenium/kg bodyweight.
Ewes and Gimmers
Dose ewes 2–6 weeks before lambing and again soon after lambing. On heavily stocked pastures, treatments at intervals of 3 – 4 weeks may be necessary until autumn. Otherwise treat prior to tupping and at housing.
Lambs and Wether Hoggs
Dosing of lambs for Nematodirus infection requires dosing at 2 week intervals. Otherwise treat lambs from 4 – 6 weeks of age and hoggs from late May at 3 week intervals until autumn. Dose at weaning and move to clean pasture. If clean pasture is unavailable, dose at 3 – 4 week intervals until sold or until early winter.
Treat all bought-in sheep before allowing to mix with the flock. (N.B. Most independent advice recommends the use of an avermectin (3-AVM) – containing product at this time).
Fluke and Worm Dose
Allverm 4% is administered at a dosage of 1 ml per 5.33 kg bodyweight. At this rate the dosages are 7.5 mg ricobendazole/kg, 1.125 mg cobalt/kg and 0.12 mg selenium/kg bodyweight.
Dose all ewes 2–6 weeks before and again soon after lambing to reduce pasture contamination roundworm eggs and control chronic fluke disease. Dose all sheep in October/November and repeat at 4–6 week intervals until spring for out wintering stock. Ewes should not be treated at the fluke and worm dose during tupping and until one month after the tups are removed.
