Description

Halofuginone is an antiprotozoal agent of the quinazolinone derivatives group (nitrogenous polyheterocycles). The compound has a cryptosporidiostatic effect on Cryptosporidium parvum. It is mainly active on the free stages of the parasite (sporozoïte, merozoïte). The bioavailability of the drug in the calf, following single oral administration, is about 80 %. The product is mainly excreted in the urine.

Indications

In newborn calves, Halosan Oral is indicated for:
 
- Prevention of diarrhoea due to diagnosed
  Cryptosporidium parvum, in farms with history of
  cryptosporidiosis, with administration to be
  started in the first 24 to 48 hours of age.
- Reduction of diarrhoea due to diagnosed
  Cryptosporidium parvum, with administration
  to be started within 24 hours after the onset of
  diarrhoea.

Contra indications

Do not inject.
Do not use Halosan Oral on an empty stomach.
Do not use in case of diarrhoea for more than 24 hours and in weak animals.
 

Side effects

In very rare cases, an increase in the level of diarrhoea has been observed in treated animals. Besides diarrhoea, symptoms of toxicity include visible blood in faeces, decline in milk consumption, dehydration, apathy and prostration. Should clinical signs of overdosing occur the treatment must be stopped immediately and the animal fed unmedicated milk or milk replacer. Rehydration may be necessary. 
For treatment of anorexic calves, the product should be administered in half a litre of an electrolyte solution. The animals should receive enough colostrum according to good breeding practice.

Dosage

For oral use in calves after feeding.
 
Calves 35 - 45 kg:
8 ml once a day for 7 days.
 
Calves 45 - 60 kg:
12 ml once a day for 7 days. 
 
Lighter or heavier calves: 1 ml per 5 kg (100 µg/kg) once a day for 7 days.
 
Use after colostrum feeding, or after milk or milk replacer feeding only. Due to toxic potential it is crucial to strictly adhere to the prescribed dose rate. Use either a syringe or any appropriate device for oral administration to ensure the correct dosage. Consecutive treatment should be done at the same time each day. Once the first calf has been treated, all the forthcoming newborn calves must be systematically treated as long as the risk for diarrhoea due to C. parvum persists.
 

Withdrawal times

Meat and offal: 13 days.
