Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.
- Induction of farrowing from day 114 of pregnancy onwards (day 1 of pregnancy is the
last day of insemination).
A single dose of 0.175 mg cloprostenol (as cloprostenol sodium) per animal
corresponding to 2 mL of product per animal once, by deep intramuscular injection,
preferably with a needle of at least 5 cm long.
It is recommended that the vial is not broached more than 10 times with a 21G needle
(or finer) and that the appropriate vial size is used for prevailing usage conditions.
Otherwise, an automatic syringe equipment, or a suitable draw-off needle, should be
used for the 50 ml vials to avoid excessive puncturing of the stopper.
Having calculated the average gestation length for each farm, sows and gilts may be
injected two days before this date or on any date thereafter to suit the requirements of
the particular management system. Trials carried out two days before the average
term have shown that normally 95% of animals will commence farrowing within 36
hours of treatment. The majority of animals can be expected to respond within the
period 24±5 hours following injection, and earlier if farrowing had already almost
spontaneously begun.
Do not use in animals with cardiovascular, gastro-intestinal or respiratory
disturbances.
Do not use to induce parturition in sows 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 use intravenously.

particularly following intramuscular injection.
When used in sows and gilts 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.
In very rare cases transient erythema and pruritus, urination and defecation, ataxia,
hyperpnea, dyspnea, nest-building behaviors, abdominal muscle spasms,
vocalization and salivation may occur following the administration of prostaglandin
F2
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)
Revised: October 2023
AN: 01832/2023
- 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).
Induction of farrowing too early in pregnancy can lead to non-viable piglets being
born. An increase in the number of non-viable piglets may result if used more than
two days prior to the average gestation length calculated from farm records.
To reduce the risk of anaerobic infections, potentially related to the pharmacological
properties of prostaglandins, avoid injecting through an area of contaminated skin.
Clean and disinfect carefully the injection sites before administration.
