Quick read

Codeine should only be taken during pregnancy if recommended by your doctor.

What is it?

Codeine (Galcodine®) is used to relieve pain and to prevent coughing. It can be prescribed or bought over-the-counter in combination with other painkillers.

Benefits

What are the benefits of taking codeine in pregnancy?

Codeine sometimes works where other painkillers have not. If your pain is well-treated, this can improve your sleep and quality of life.

Risks

Are there any risks of taking codeine during pregnancy?

Most studies do not show that codeine use in pregnancy will harm your baby. Some (but not all) studies have shown that babies exposed to codeine in early pregnancy may be slightly more likely to be born with a heart defect. It is unclear whether this is directly caused by codeine and more research is needed.

Codeine used around the time of delivery can affect your baby after birth. Your baby may have withdrawal symptoms, such as being unusually irritable or shaky, have feeding problems, and need some help with breathing. These problems usually settle within the first few days.

Alternatives

Are there any alternatives to taking codeine?

Possibly. Other medicines can be used to treat pain in pregnancy. However, if your doctor has suggested codeine, this will be based on several factors. These include which painkillers you have already tried, the chance of your pain not being as well-controlled with another painkiller, and possible side effects if your medicine is changed. 

If you are taking codeine and planning a pregnancy, or you find out you are pregnant, please speak to your doctor. They will review whether codeine is still the best treatment and ensure that your dose is correct.

No treatment

What if I prefer not to take medicines during pregnancy?

Pain can greatly affect your quality of life. It can cause difficulty sleeping and mental health problems. Your doctor might suggest you take codeine in pregnancy if they think that the benefits of controlling your pain outweigh any possible risks to your baby.

Will my baby need extra monitoring?

Women in the UK will be offered a very detailed scan at around 20 weeks of pregnancy as part of their routine antenatal care. Taking codeine in pregnancy is not expected to cause problems that would require any extra monitoring of your baby prior to birth. 

Babies who were exposed to codeine in the womb before delivery will be more closely monitored for a while after birth to check for withdrawal symptoms and ensure they are breathing and feeding normally.

Are there any risks to my baby if the father has taken codeine?

We do not expect any increased risk to your baby if the father takes codeine.

Who can I talk to if I have questions?

If you have any questions regarding the information in this leaflet, please discuss them with your health care provider. They can access more detailed medical and scientific information from www.uktis.org.

How can I help to improve drug safety information for pregnant women in the future?

Our online reporting system (MyBump Portal) allows women who are currently pregnant to create a secure record of their pregnancy, collected through a series of questionnaires. You will be asked to enter information about your health, whether or not you take any medicines, your pregnancy outcome and your child's development. You can update your details at any time during pregnancy or afterwards. This information will help us better understand how medicines affect the health of pregnant women and their babies. Please visit the MyBump Portal to register.

General information
Sadly, miscarriage and birth defects can occur in any pregnancy.

Miscarriage occurs in about 1 in every 5 pregnancies, and 1 in every 40 babies are born with a birth defect. This is called the ‘background risk’ and happens whether medication is taken or not.

Most medicines cross the placenta and reach the baby. For many medications this is not a problem. However, some medicines can affect a baby’s growth and development.

If you take regular medication and are planning to conceive, you should discuss whether your medicine is safe to continue with your doctor/health care team before becoming pregnant. If you have an unplanned pregnancy while taking a medicine, you should tell your doctor as soon as possible.

If a new medicine is suggested for you during pregnancy, please make sure that the person prescribing it knows that you are pregnant. If you have any concerns about a medicine, you can check with your doctor, midwife or pharmacist.

Our Bumps information leaflets provide information about the effects of medicines in pregnancy so that you can decide, together with your healthcare provider, what is best for you and your baby.
