In clinical practice, there are currently no data of sufficient relevance to evaluate the possible malformative or foetotoxic effect of aurothiopropanolsulfonate when administered during pregnancy. As a result, its use is not recommended during pregnancy. This element does not constitute the systematic argument for counseling a termination of pregnancy but leads to an attitude of caution and oriented antenatal surveillance.
