Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Diane and Krimson both have the same composition that is Cryproterone and Ethinyl Estradiol. So you can take Krimson without any worry. I hope that answers your question. If you have any further questions please feel free to write. Thank you for choosing healthcare magic.
