Contraindication: A contraindication is a reason a medicine should not be used, or should only be used with great caution, because the risk is too high.
Patients often see the term in leaflets and pharmacy materials.
NICE specifically tells prescribers to consider pregnancy, breastfeeding, cardiovascular disease and mental health history.
Contraindications can relate to pregnancy, breastfeeding, psychiatric history, heart disease or allergies, depending on the product.
