I asked my RE about this and was told never. If it is too thick they will wipe it away.
I found this great site for info on taking a mucus relief pill. You should check it out....it explains dosing and many other things. http://www.*************.***/faq/cm.html Good Luck to you!!! And my RE had no problem when I told him I was taking this.
