NCT01185678

Brief Summary

Adherence to the dosing scheme is the principal element of COC efficiency. On the other hand noncompliance seemed to be an inseparable element of any oral treatment. The aim of the study is to evaluate in everyday practice the relation between dosage errors and indicated factors, potentially influencing the compliance with the dosing scheme.
