The limited information available indicates that these medicines do not increase the frequency of malformations but some observations may be required.
The limited information available indicates that these medicines do not increase the frequency of malformations, however monitoring is required. This may include blood tests for therapeutic drug levels, liver function or thyroid function. Monitoring of maternal and fetal wellbeing as well as any potential adverse effects in the newborn may be required.
For medicines that have no human pregnancy experience or very few cases of pregnancy exposure, an alternative medicine should be considered. The use of these medicines may have been associated with developmental toxicity such as growth restriction, structural defects or death. The medicine should not be used in pregnancy, but when it is the only medicine available, the benefits versus risks of use need to be discussed with the pregnant woman.
Medicines that have teratogenic, or irreversible undesirable effects, or are associated with developmental toxicity such as growth restriction, structural defects, functional or behavioural deficits, or death. These medicines are to be avoided throughout pregnancy. Consultation with a specialist is highly recommended. Women who have been exposed to these agents may require further counselling.
