Abstract
The most common form of combined hormonal contraception currently include oral preparations. They achieved very good safety and tolerance during development and on the other hand, they have some limits - e.g. common reliability 99% applies only in case of an error-free usage, whereas in real life could be its reliability in the first year of usage significantly lower (92 ? 97%).
Lower reliability is mainly due to insufficient compliance, in terms of irregular usage or non-compliance with the instructions for use in case of medicinal interactions, gastrointestinal complaints, etc.
