Pregnancy and medicine


Medication use in pregnancy remains a grey area, and many women and their partners struggle with conflicting information and advice offered to them while pregnant or while planning for a pregnancy. Complications can occur during pregnancy, and a significant number of pregnant women will also have a chronic illness or medical condition. This issue also impacts women with an existing medical condition who may want to become pregnant. Access to timely and appropriate care and information during pregnancy is vital for a safe and positive motherhood experience.

The issue

The decision to have a child isn’t always an easy one and can be even harder if there is a disease or illness involved. Despite the major advances in medical science, we are still lacking proper data and approximately 90% of pregnant women take medicine without knowing the consequences.

Currently, information on pregnancy and medicine is not easily available. Both clinicians and patients do not have the tools or the specialist knowledge to make informed decisions when it comes to taking medication during pregnancy. So, very often the choices are to either stop taking medicine, to take medicine and live with the uncertainty, or to avoid pregnancy altogether.

This problem has grown from the understandable lack of research and from the “zero risk” approach to medical research and practice. This approach has caused an information void, leaving potential future parents and healthcare professionals to make an impossible choice: Should a woman with cancer or rheumatoid arthritis take medication without knowing how it might impact her child? Or should she forego treatment during pregnancy, perhaps endangering her own health as well as the health of her child?

Faced with this impossible decision, many choose to renounce having children, or in many cases, are advised not to have children.

Which medicines are safe?

If you are trying for a baby or are already pregnant, it is important to:

  1. Always check with your doctor, midwife or pharmacist before taking or stopping any prescribed or over-the-counter medicine, as it is important to understand possible effects on your baby. Your doctor can answer questions such as:
    • Is this the only medication available for my condition? Are there alternatives?
    • What are the risks for me and my baby if I take this medicine? What are the risks if I don’t?
    • What is the effect of pregnancy on my disease?
    • Have other pregnant women taken this treatment?
    • Where can I get more information?
  2. Make sure your doctor, dentist or other healthcare professional knows you’re pregnant before they prescribe anything or give you treatment
  3. Talk to your doctor immediately if you take regular medication, ideally before you start trying for a baby or as soon as you find out you are pregnant
  4. Do not stop taking a medicine that has been prescribed to keep you healthy without first checking with your doctor. Doing so could be harmful to both you and your baby
  5. Be aware that not all "natural" remedies or complementary therapies are safe in pregnancy

Remember that you have the right to ask for a second opinion. Don’t be afraid to ask another doctor or doctors what they think.

Finding information about medicines

There are also places where you can access information on medicines during pregnancy. Some examples include the bumps (best use of medicines in pregnancy) website, which also has advice on what to do if you have already taken a medicine in pregnancy, Motherisk, and LactMed, which has information for women who are breastfeeding. See below for more information.

If you have further questions, you or your healthcare professional can also try to contact your local teratology information organization. A list of centers in Europe can be found here.
