Will my medication affect my baby?

It depends on the type of medication. Some types of medication for mental health problems have risks for your baby if you take them when you are pregnant or when you are breastfeeding.

It is important to tell your doctor as soon as possible that you are pregnant so that your treatment can be discussed and considered with you.

Although some medication may have risks for your baby, if you stop medication suddenly you may become unwell very quickly so it is important to talk to your healthcare team first.

Your doctor should talk to you about:

  • the benefits and risks of carrying on with your current medication
  • the benefits and risks of switching to another medication that’s safer for pregnancy
  • the benefits and risks of switching to a ‘talking treatment’ (psychological therapy)
  • the possible effects of stopping or switching  your medication suddenly.

The type of mental health condition and severity will be a factor in these decisions. 

If you decide to take medication when you are pregnant or when you are breastfeeding, you should be offered the type with the least risk for you and your baby. You should be offered the lowest amount that will still work and should usually not take more than one type.

If you would like to stop medication when you are pregnant, but medication is the best treatment for your mental health problem, your doctor should talk to you about your reasons for wanting to stop medication and about the risks to you and your baby.
