Do not administer to induce parturition in sows and cows with suspected dystocia due to mechanical obstruction or if

problems are expected because of an abnormal position of the foetus.

4.4 Special warnings for each target species

The response of cows to the synchronization protocols is not homogenous nor between the herds, neither within the same

herd, and may vary depending on the physiological state of the animal at the time of treatment (sensitivity and a functional

state of the corpus luteum, age, physical condition, interval from calving, etc.).

4.5 Special precautions for use

Special precautions for use in animals

Induction of parturition and abortion may increase the risk of complications, retained placenta, foetal death and metritis.

To reduce the risk of anaerobic infections, 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


In case of oestrus induction in cows: from the 2nd day after injection, adequate heat detection is necessary.

Induction of parturition in sows before day 114 of gestation may result in an increased risk of stillbirths and the need for

manual assistance at farrowing.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Prostaglandins of the F2α type can be absorbed through the skin and may cause bronchospasm or miscarriage.

Pregnant women, women of child-bearing age, asthmatics and people with bronchial or other respiratory problems, should

avoid contact with, or wear disposable impervious-gloves when administering the product. Care should be taken when

handling the product to avoid self-injection or skin contact.

In case of accidental spillage onto the skin, the area involved should be washed immediately with soap and water.

Should shortness of breath result from accidental inhalation or injection, seek medical advice and show the package leaflet or

the label to the physician.

4.6 Adverse reactions (frequency and seriousness)

Occurrence of anaerobic infection is common if anaerobic bacteria penetrate the tissue of the injection site. This applies

especially to intramuscular injection and in particular to cows. Typical local reactions due to anaerobic infection are swelling

and crepitus at the injection site. When used for induction of parturition and depending on the moment of treatment relative

to the date of conception, increase of placental retention rate can occur.

Behavioural changes in sows observed after treatment for induction of farrowing are similar to those changes associated with

natural farrowing and usually cease within 1 hour.

Adverse reactions in horses including sweating (occurring within 20 minutes of treatment), increased respiratory and cardiac

rates, signs of abdominal discomfort, watery diarrhoea and depression may occur when exceptionally high doses are given.

However adverse reactions are usually mild and transient

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)

4.7 Use during pregnancy, lactation or lay

Do not administer to pregnant animals unless the objective is to terminate the pregnancy.

The product can be used safely during lactation.

4.8 Interaction with other medicinal products and other forms of interactions

Do not administer the product together with nonsteroidal anti-inflammatory drugs since they inhibit endogenous

prostaglandin synthesis. The activity of other oxytocic agents can be increased after the administration of the product.

4.9 Amounts to be administered and administration route

For intramuscular administration only.


Administer one dose (2 ml) per animal of product (equivalent to 150 micrograms of d-cloprostenol per animal):

- Induction of oestrus (also in cows showing weak or silent heat): administer one dose of the product after having established

the presence of a corpus luteum (6

day of the cycle). Heat usually appears within 48-60 hours. Proceed with insemination

72-96 hours after injection. If oestrus is not evident, administration of the product needs to be repeated 11 days after the first


- Synchronisation of oestrus: administer one dose of the product twice (with an interval of 11 days between each dose).

Proceed therefore with two artificial inseminations at intervals of 72 and 96 hours from the second injection.

D-cloprostenol may be used in combination with GnRH, with or without progesterone, in the protocols for synchronisation of

the ovulation (Ovsynch protocols). The responsible veterinarian shall decide the protocol to be used, basing on the objective of

the treatment, and on the herd and animals to be treated. The following protocols have been evaluated and may be used:

In cycling cows:

- Day 0: inject GnRH (or analogous).

- Day 7: inject d-cloprostenol (one dose of the product).

- Day 9: inject GnRH (or analogous).

- 16-24 hours later perform artificial insemination.

Alternatively in cycling or not-cycling cows and heifers:

- Day 0: insert the intravaginal device for progesterone delivery and inject GnRH (or analogous).

- Day 7: remove the intravaginal device and inject d-cloprostenol (one dose of the product).

- Day 9: inject GnRH (or analogous).

- 16-24 hours later perform artificial insemination.

- Induction of parturition: administer one dose of the product. Birth usually occurs within 30-60 hours of treatment.

- Ovarian dysfunction (persistent corpus luteum, luteal cyst): once a corpus luteum has been detected, administer on dose

of the product and inseminate at the first oestrus after injection. If oestrus is not evident, conduct a further gynaecological

examination, and repeat the injection 11 days after the first administration. Insemination must be carried out 72-96 hours after


- Clinical endometritis with the presence of a functional corpus luteum, pyometra: administer one dose of the product. If

necessary, repeat the treatment after 10 days.

- Delayed uterine involution: administer one dose of the product and, if considered necessary, carry out one or two

successive treatments at 24 hours intervals.

- Induction of abortion: administer one dose of the product in the first half of pregnancy.

- Mummified foetus: expulsion of the foetus is observed within 3-4 days after administration of one dose of the product.


For the induction of luteolysis in mares with a functional corpus luteum: administer a single injection of 1 ml of product/animal

(equivalent to 75 micrograms of d-cloprostenol).

For the induction of parturition in sows: administer 1 ml of the veterinary medicinal product, equivalent to 75 micrograms of

d-cloprostenol/animal, by intramuscular route, not earlier than 114 days of pregnancy. The injection can be repeated after 6


The rubber stopper of the vial can be safely punctured up to 20 times. Otherwise, for the 100 ml vials automatic syringe

equipment, or a suitable draw-off needle, should be used to prevent excessive puncture of the closure.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

At 10 times the therapeutic dose, no adverse reactions were reported in cows and sows.

In general, a large overdose could result in the following symptoms: increased pulse and breathing rate, bronchoconstriction,

increased body temperature, increased amounts of loose faeces and urine, salivation and vomiting. As no specific antidote has

been identified, in the case of overdose, symptomatic therapy is advisable. An overdose will not accelerate corpus luteum


In mares, moderate sweating and soft faeces were detected when the product was administered at 3 times the therapeutic


4.11 Withdrawal period(s)

Milk: zero hours.


Meat and offal: 1 day


Meat and offal: 2 days

Milk: zero hours


Pharmacotherapeutic group: other gynecologicals, prostaglandins.

ATCvet code: QG02AD90

5.1 Pharmacodynamic properties

The veterinary medicinal product is a sterile aqueous solution containing dextrorotatory cloprostenol, a synthetic analogue of

the prostaglandin F2α. The dextrorotatory enantiomer, d-cloprostenol, constitutes the biologically active (luteolytic)

component of the racemic cloprostenol molecule. The veterinary medicinal product is approximately 3.5 times more active

than similar veterinary medicinal products containing racemic cloprostenol, thus it can be administered at a proportionally

lower dose level.

During the luteal phase of the oestrus cycle, d-cloprostenol induces a reduction of the number of receptors for luteinizing

hormone (LH) in the ovary, which leads to a rapid regression of the corpus luteum.

5.2 Pharmacokinetic particulars

In cows, the highest plasma concentration of d-cloprostenol was found at 90 minutes after injection (approximately 1.4 μg/l).

Elimination half-life is 1 h 37 minutes.

In sows, the highest plasma concentration is reached within 30 - 80 minutes after the injection. The elimination half-life is

approximately 3 h and 12 minutes.
