2. The authors are not presenting any information about when gestation women were recruited into the study, and/or the average gestational time when the interview was conducted. This is important information since women in the end of pregnancy have a full overview of the entire pregnancy, and can thereby report about OTC use. On the other hand, women in early pregnancy might have not have the chance yet to use a OTC medication for instance, and they have no overview of the entire pregnancy. At least, sensitivity analyses restricted to women in third trimester should be considered.

Information that pregnant women were picked regardless of gestation age has been added in the sampling procedure section. We included all gestation ages because each age has its importance as far as self-medication is concerned. In the first trimester women are prone to selfmedicate due to nausea, vomiting and other symptoms and it is a risk period to the foetus as malformations are likely to develop while in the last trimester chances of abortions are increased due to drug use.
