Contra-indications, warnings, etc
Do not administer to pregnant animals unless the objective is to terminate the pregnancy.
Do not use in animals with cardiovascular, gastro-intestinal or respiratory disturbances.
Do not administer to induce parturition in cattle with suspected dystocia due to mechanical obstruction or if problems are expected because of an abnormal position of the foetus.
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
Do not administer intravenously.
Special warnings for each target species
There is a refractory period of four to five days after ovulation when cattle are insensitive to the luteolytic effect of prostaglandins.
Special precautions for use
Special precautions for use in animals
In case of oestrus induction in cattle: from the 2nd day after injection, adequate heat detection is necessary.
For the termination of pregnancy, best results are obtained before day 100 of gestation. Results are less reliable between day 100 and 150 of gestation.
Induction of parturition and abortion may increase the risk of complications, retained placenta, foetal death and metritis.
To reduce the risk of anaerobic infections (e.g. swelling, crepitus), which might be related to the pharmacological properties of prostaglandins, care should be taken to avoid injection through contaminated areas of skin. Clean and disinfect injection sites thoroughly before administration.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Prostaglandins of the F2α- type, such as cloprostenol, can be absorbed through the skin and mucous membranes and may cause bronchospasm or miscarriage.
Direct contact with the skin or mucous membranes of the user should be avoided.
Care should be taken when handling the product to avoid self-injection or skin contact.
Pregnant women, women of child-bearing age, asthmatics and people with bronchial or other respiratory problems should avoid any contact with the product.
Wear disposable impervious gloves when administering the product.
Wash hands after use.
Do not eat, drink or smoke while handling the product.
Accidental spillage on the skin should be washed off immediately with soap and water.
In case of accidental self-injection or spillage onto the skin seek medical advice immediately, particularly as shortness of breath may occur, and show the package leaflet or label to the physician.
Adverse reactions (frequency and seriousness)
Localised post-injection bacterial infections, which may become generalised, are occasionally reported.
When used in cattle for induction of parturition and dependent on the time of treatment relative to the date of conception, the incidence of retained placenta may be increased.
Anaphylactic-type reactions can be observed in very rare cases, which might be life-threatening and require rapid medical care.
The frequency of adverse reactions is defined using the following convention:
- Very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- 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).
Use during pregnancy and lactation
Do not administer to pregnant animals unless the objective is to terminate the pregnancy.
Lactation: Use only according to the benefit/risk assessment by the responsible veterinarian.
Interaction with other medicinal products and other forms of interaction
Do not administer the product together with non-steroidal anti-inflammatory drugs since they inhibit endogenous prostaglandin synthesis.
The activity of other oxytocic agents can be increased after the administration of cloprostenol.
Overdose may be associated with uneasiness, increased heart rate, increased respiratory rate, bronchoconstriction, increased rectal temperature, increased urination, salivation and diarrhoea. These effects are usually transient and will resolve without treatment.
No antidotes are available.
In the absence of compatibility studies, this veterinary medicinal product must not be mixed with other veterinary medicinal products.
