Kriptazen
Active substance
ATC code
Species
Cattle (newborn calves).
Indications
In new born calves:
- Prevention of diarrhoea due to diagnosed Cryptosporidium parvum, in farms with history of cryptosporidiosis.
Administration should start in the first 24 to 48 hours of age.
- Reduction of diarrhoea due to diagnosed Cryptosporidium parvum.
Administration should start within 24 hours after the onset of diarrhoea.
In both cases, the reduction of oocysts excretion has been demonstrated.
Dose to be administered and administration route
For oral use in calves after feeding.
The dosage is: 100 μg of halofuginone / kg bw, once a day for 7 consecutive days; i.e. 2 ml of Kriptazen / 10 kg bw, once a day for 7 consecutive days.
The consecutive treatment should be administered at the same time each day. Once the first calf has been treated, all the forthcoming new-born calves must be systematically treated as long as the risk for diarrhoea due to C. parvum persists.
Bottle without a pump: To ensure a correct dosage, the use of either a syringe or any appropriate device for oral administration is necessary.
Bottle with a pump: To ensure a correct dosage, the most appropriate metering pump should be selected, depending on the weight of the animals to be treated. In cases where the dosing pump is unsuitable for the weight of animals to be treated, either a syringe or any other appropriate device can be used.
4 ml pump
1) Choose the dip tube designed for the height of the bottle (the shorter one for the 490 ml bottle and the longer one for the 980 ml bottle) and insert it into the free hole located in the base of the pump cap.
2) Remove the cap and the protective seal from the bottle and screw the pump on.
3) Remove the protector cap from the tip of the nozzle of the pump.
4) Prime the pump by pressing the trigger gently, until a drop appears at the tip of the nozzle.
5) Restrain the calf and insert the nozzle of the metering pump into its mouth
6) Pull the trigger of the metering pump completely for release of a dose that equals 4 ml of solution. Pull two or three times, respectively, for administration of the desired volume (8 ml for calves weighing more than 35 kg but less than or equal to 45 kg and 12 ml for calves weighing more than 45 kg but less than or equal to 60 kg).
For lighter or heavier animals, a precise calculation should be performed (2 ml/10 kg bw).
7) Continue using until the bottle is empty. If product remains in the bottle, leave the pump attached until further use.
8) Always replace the cap on the tip of the nozzle after use.
9) Always replace the bottle in the box.
4 to 12 ml pump
1) Choose the dip tube designed for the height of the bottle (the shorter one for the 490 ml bottle and the longer one for the 980 ml bottle) and insert it into the free hole located in the base of the pump cap.
2) Remove the cap and the protective seal from the bottle and screw the pump on.
3) Remove the protector cap from the tip of the nozzle of the pump.
4) To prime the pump, turn the dosage ring and select 60 kg (12 ml).
5) Press the trigger gradually with the cannula pointed up, until a drop appears at the tip of the nozzle.
6) Turn the ring, in order to select the weight of the calf to be treated.
7) Restrain the calf and insert the nozzle of the metering pump into its mouth.
8) Pull the trigger of the metering pump completely for release of the adequate dose.9) Continue using until the bottle is empty. If product remains in the bottle, leave the pump attached until further use.
10) Always replace the cap on the tip of the nozzle after use.
11) Always replace the bottle in the box.
Adverse reactions
An increase in the level of diarrhoea has been observed in rare cases, in treated animals.
The frequency of adverse reactions is defined using the following convention:
- Very common (more than 1 in 10 animals treated displaying adverse reactions)
- Common (more than 1 but less than 10 animals in 100 animals treated)
- Uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- Rare (more than 1 but less than 10 animals in 10,000 animals treated)
- Very rare (less than 1 animal in 10,000 animals treated, including isolated reports).
