Re: pms…a real problem?
Im almost 100% sure about this. I remember during my GP block I had to ask this question and explain this to patients like 10 times a day.
This is from a paper published Titled ’ Interactions of the oral contraceptive pill with antibiotics and St John’s wort: knowledge of female college students’
Meena Hindmarch and Pippa Oakeshott
These results suggest that many young women taking the OCP may be unaware of drugs that decrease its effectiveness. This may leave them more susceptible to pregnancy if they do not realise they should be taking extra precautions. This was particularly so with respect to the interaction with St John’s wort. Since GPs and practice nurses are an important source of the OCP for young women, they should consider mentioning the need for extra precautions not only with antibiotics, but also with St John’s wort.
