£22.73 (inc VAT)

Clear, sterile, aqueous solution of oxytocin equivalent to 10 i.u. per ml (0.18 mg/ml). Chlorbutanol 5 mg/ml is included as a preservative.  

Oxytocin-S initiates strong, regular and purposeful contractions of the uterine muscle especially in the later stages of pregnancy and post-partum. It evokes the let down' of milk although it has no action on the smooth muscles of the gut or urinary bladder, nor is it effective in the treatment of diabetes insipidus. The absence of vasopressor and antidiuretic effects make Oxytocin-S particularly suitable for obstetric use (stimulation of parturition, promotion of uterine involution and control of post-partum haemorrhage) and the treatment of agalactia.


  • stimulation of uterine contraction to facilitate parturition in the presence of a fully dilated cervix
  • to promote involution of the post-parturient uterus and thus aid the passage of retained placenta
  • to aid in the control of post-partum haemorrhage
  • promotion of milk let-down' in cases of agalactia and to facilitate stripping out' of infected quarters in the treatment of mastitis in cows.

Legal Category: POM-V                 


Oxytocin-S should normally be given by deep intramuscular injection.

Cat: 0.2-0.5ml

Dog: 0.2-1ml

Ewe, goat, sow: 0.2-1ml

Mare: 1-4ml

Cow, indications other than mastitis: 1-4ml

Cow, adjunct to mastitis treatment: single dose of up to 8 ml prior to stripping out before the first mastitis treatment, followed by repeated doses of 2 ml prior to each stripping out 2/3 times daily while mastitis treatment continues.

Where the intravenous route is used, these doses should be reduced to one-quarter of the intramuscular dose and the injection given slowly at a dilution of 1 in 10 Water for Injections PhEur. Where speed of onset is not a priority, Oxytocin-S may be given by the subcutaneous route.

A low initial dosage is recommended by any route as repeat administration is permissible. Large doses may be employed in post-parturient animals.

Withdrawal Period

Cattle, horses, pigs, sheep and goats: Meat – zero days.

Cattle, sheep and goats: Milk – zero hours.

Contra Indications

When Oxytocin-S is used as an aid to parturition, cervical dilation must be confirmed prior to administration to prevent the risk of foetal death and possible uterine rupture.

Oxytocin-S is contra-indicated in any form of obstructive dystocia.

Excessive doses of the product may delay parturition by producing incoordinated uterine contractions which interfere with the progress of the foetus especially in multiple pregnancies.

The effects of daily dosages of 100 i.u. or more (to facilitate 'stripping out' of infected quarters in the treatment of mastitis in cows) on the oestrous cycle have not been fully investigated and the cycle length may be altered.

Adrenaline at physiological levels markedly reduces effect of oxytocin on the uterus or mammary gland. For this reason the animal should not be frightened when complete oxytocin effect is desired to cause either milk 'let-down' or uterine contractions.
