What Oxytocin Pilum is and what it is used for

Oxytocin Pilum contains oxytocin. Oxytocin is a hormone that causes contractions in the smooth muscles of the uterus.

Oxytocin is used:

  • to initiate labor, in case of mild pain
  • in case of miscarriage, abortion
  • to reduce and control postpartum hemorrhage
  • by cesarean section.

Oxytocin contained in Oxytocin Pilum may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professionals if you have any further questions, and always follow their instructions.

What you need to know before using Oxytocin Pilum

Do not use Oxytocin Pilum

  • if you are allergic to oxytocin or any of the other ingredients of this medicine (listed in section 6).
  • if your doctor/midwife considers that it is not appropriate for you to start or increase the contractions in the uterus, eg:
    • when there are obstacles that can stop the birth
    • when labor or vaginal delivery is inappropriate
    • when the contractions of the uterus are unusually strong
    • when your child may be deprived of oxygen.

How to use Oxytocin Pilum

Your doctor or midwife will decide when and how you should be treated with Oxytocin Pilum. Oxytocin Pilum is usually diluted before being given as an intravenous drip into a vein.

Dose one varies depending on what it is used for. Your doctor or midwife will prescribe a dose that can be changed if necessary depending on the effect of the medicine.

To initiate labor, in case of mild pain

Infusion one begins at a slow pace. The infusion rate is increased until the pains are sufficient. Thereafter, the infusion rate can often be reduced.

Your pain and your baby’s heartbeat will be closely monitored during the time you receive Oxytocin Pilum.

If the pain has not become effective enough after giving an ampoule, the test is stopped and possibly repeated the next day.


During an abortion, an intravenous infusion is given at a faster rate.

Cesarean section

An ampoule is given as an intravenous infusion after the baby is born.
