Writer's note: 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," on a regular basis. If there are terms you'd like to have defined, please leave a comment below.

When we're given migraine and headache information, whether from our doctor, a book, or an online article, we sometimes come across medical terms that can be confusing. While it's easy enough to substitute another word or a short phrase for the medical term, there are times when substituting doesn't quite convey the same meaning.

Side Effects is one of those terms.** Side effects** are any undesired actions or effects of a drug or treatment. Negative or adverse effects may include headache, nausea, hair loss, skin irritation, or other physical problems. Experimental drugs must be evaluated for both immediate and long-term side effects. We sometimes discuss potential** side effects** when discussing Migraine and headache medications -- prescription AND over-the-counter, dietary supplements, and other treatments.
