Applicant's summary and conclusion

Conclusions:

From 30 females who were exposed to Dioctyl sodium sulfosuccinate in months 1-4 of pregnancy, 3 gave birth to malformed children.
From 116 females who were exposed to Dioctyl sodium sulfosuccinate any time during pregnancy, 3 gave birth to malformed children.
There was no evidence to suggest that exposure to drugs taken for gastrointestinal disturbances (440 mother-child pairs) increases the risk of malformations. However, numbers were small and associations between specific drugs and various malformations could not be ruled out.
