Can I take an antiarrhythmic drug if I get pregnant / wish to breastfeed?
Like most drugs, antiarrhythmic drugs should be used with caution during pregnancy or breast feeding. Although some drugs are quite safe, others should be avoided as they can have an adverse effect on a baby’s development. If you are planning a pregnancy, you should mention this to your cardiologist or arrhythmia nurse. They will be able to advise you what is the safest option. Your pharmacist might also be able to give helpful advice. If you have an unplanned pregnancy, it is important to seek medical advice straight away as there may be a safer alternative drug for you to take.
