Necon 7/7/7 - Are there any side effects when mixing Necon 777 with Doryx?

8 Sep 2009

You shouldn't really get any side effects as such, but the effectiveness of the pill may be reduced when you take Doryx (doxycycline - antimicrobial) with Necon 777.

An alternative or additional method of birth control should be considered during and for at least one week beyond the last dose of short-term antimicrobial therapy (and for at least the initial weeks of long-term antimicrobial therapy when risk may be the greatest).
