Bisoprolol
What is it?
Bisoprolol is mainly prescribed to treat heart failure and high blood pressure (hypertension).
Benefits
What are the benefits of using bisoprolol?
Bisoprolol reduces the risk from high blood pressure and some heart problems. This is important as these conditions can get worse during pregnancy and may lead to complications.
Some women will be taking bisoprolol before pregnancy. If so, it can be continued but should be reviewed at the earliest opportunity by your midwife, GP, cardiologist, or obstetrician.
Risks
Are there any risks of using bisoprolol in pregnancy?
A small number of pregnant women specifically taking bisoprolol have been studied, with no concerns raised that its use causes miscarriage or birth defects. Bisoprolol belongs to a family of medicines called beta blockers. Studies have also not shown that beta blockers cause birth defects, stillbirth, or preterm birth. Women taking beta blockers may be more likely to have a small baby. However, a small baby can be due to underlying health conditions that beta blockers are commonly used to treat, like high blood pressure. It is therefore difficult to know if a beta blocker has also contributed to the baby being small.
Occasionally, beta blockers used in late pregnancy can affect the baby for a short while after birth (for example, causing low blood sugar). The baby may require an extra day or two in hospital following birth to look out for any problems. If these occur, they can be easily treated and usually settle quickly.
Alternatives
Are there any alternatives to using bisoprolol?
Possibly. Other medicines can be used to treat high blood pressure and heart failure. You should let your midwife, GP and/or obstetrician know that you are taking bisoprolol so that it can be reviewed as soon as possible. If you have any questions about a medicine that you are offered in pregnancy, you can discuss them with your doctor or midwife.
No treatment
What if I prefer not to take medicines in pregnancy?
It is very important to take any medicines prescribed for high blood pressure or heart problems. High blood pressure can lead to a potentially serious condition called pre-eclampsia. Heart problems can also be dangerous to both mother and baby and must be as well-controlled as possible.
Your doctor will only prescribe medicines when absolutely necessary and will be happy to talk to you about any concerns that you might have.
Please do not stop bisoprolol without speaking to your midwife, GP, cardiologist or obstetrician.
Will my baby need extra monitoring?
You will be offered a detailed scan at around 20 weeks of pregnancy, as part of routine antenatal care. If you continue bisoprolol then you may be offered additional scans at around 32 and 36 weeks to check that your baby is growing normally.
Are there any risks to my baby if the father takes bisoprolol?
We would not expect any increased risk to your baby if the father takes bisoprolol.
