Effydral is intended for oral administration only.

Effydral solution is prepared by adding 1 effervescent tablet to 1 litre of luke-warm (about 37°C) water. The solution should be freshly made up just prior to feeding, using clean water and utensils.

If solution has been stored in a refrigerator (2-8°C), gently warm to 37°C before administration.

(i) Calves with diarrhoea: Treatment should commence immediately diarrhoea is noticed. Withdraw milk or milk replacer and feed 2 or 3 litres of Effydral solution, depending on calf size or severity of diarrhoea, twice daily for 2 days. During the next 2 days, feed 1 or 1.5 litres of Effydral solution mixed with an equal quantity of milk or milk replacer. Normal feeding can then usually be resumed.

In cases of severe dehydration Effydral solution should be administered in 3 or 4 feeds per day. If necessary the solution may be administered by stomach tube. Normally, calves can be fed Effydral solution exclusively for up to 4 days without harmful effects.

(ii) Bought-in calves: Instead of milk or milk replacer the first feed on arrival should consist of 2 litres of Effydral solution. The second feed should contain 1 litre of Effydral solution mixed with 1 litre of milk or milk replacer. Thereafter feed as normal.

(i) Birth to weaning: When scour occurs make Effydral available ad libitum in a clean utensil. The amount consumed per pig depends on age.

(ii) Weaned pig: Allow ad libitum consumption up to a maximum of 1 litre per pig per day. Provide untreated water at all times.
