Migraine Term of the Day: b.i.d.

Teri Robert @trobert Health Guide
  • When we're looking at Migraine and headache information, whether it's from our doctor, a book, or an online article, we sometimes come across medical terms that can be confusing.


    Sometimes, it's easy enough to substitute another word or a short phrase for the medical term. At other times, substituting just doesn't convey quite the same meaning or takes more than a few words.


    Some of you have expressed an interest in learning more of the medical terminology that comes up when discussing Migraine disease and other headache disorders. So, I'll be posting a "term of the day," probably a couple of times a week. If there are terms you'd like to have defined, please leave a comment to let me know what it is.

    Today's term: b.i.d.


    b.i.d. is an abbreviation used in writing prescriptions or instructions for taking medications. It is from the Latin bis in die and means twice a day.


    We sometimes see b.i.d. when discussing Migraine and headache medications.
