Trileptal and Estrogen Containing Pills

Apparently Trileptal can render birth control pills much less effective.  So if your daughter is prescribed estrogen-containing medications for any reason other than regulating her cycle or clearing her skin, you need to realize that it will not be an effective method of pregnancy prevention.  Just thought I would share this.  I found this out from another mom who is a moderator for the CABF support group I am a part of.  Always good to know about drug interactions!  Sometimes the psychiatrists are not always aware of these things!  Or the gyns as I discovered!
