Induction methods: Understanding the Options Your Team May Offer

Induction uses clinical treatment to start labour. The method offered depends on why birth is recommended, the condition of your cervix, your baby’s wellbeing and your medical and birth history. It is not a fixed sequence that everyone must complete.

Begin with assessment and the reason for birth

Ask why induction is being recommended now, what benefits and risks apply to you and what the alternatives would involve. The team will assess you and your baby before treatment. With your consent, a vaginal examination can help assess how ready the cervix is to open; this is sometimes described using a Bishop score.

A membrane sweep may have been offered beforehand. It is different from the medicines and devices used for a planned induction, and an unsuccessful sweep does not establish that another method will fail.

Helping the cervix prepare

If the cervix needs preparation, options include medicines such as prostaglandins or a mechanical method. Medicines may be given vaginally or by mouth, depending on the product and the care plan. A balloon catheter or another cervical dilator works by helping the cervix open mechanically.

Medicines can sometimes make contractions too frequent or prolonged, which can affect the baby. This is why monitoring and reassessment matter. Mechanical methods are less likely to cause excessive uterine activity and may be considered when medicines are unsuitable or when you prefer that approach.

Breaking the waters and using an infusion

When the cervix and other findings make it appropriate, the team may recommend deliberately breaking the waters. An oxytocin infusion through a vein may then be offered to encourage contractions. Staff adjust treatment and monitor contractions and the baby; these treatments are not for use without maternity supervision.

Ask what each step aims to achieve, how you will be monitored and what happens if you want to pause or reconsider. Our induction timing guide explains why preparation and established labour can have different timelines.

Make previous surgery and preferences part of the decision

A previous caesarean or other surgery on the womb changes the assessment because some induction medicines are unsuitable and risks can differ. Make sure the team knows your history. Discuss the relative options rather than assuming a method used by someone else is appropriate.

Induction does not remove your need for pain relief, explanations or consent. Ask about available support, movement and the next review. If a method does not work, the team should reassess you and the baby and discuss the next options, which may include another approach or a caesarean.
