PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Are these adverse drug reactionns or side effects? Which way to think

First I would like to laud the efforts of authors who discussed this important topic. Generally, whenever during lecture I use to teach my students the side effects of medicines, diarrhea and/or constipation are the two major side effects reported almost with every medicine profile. I had one concern which might be addressed by the authors. What is the parameter to differentiate between side effects and adverse effects? Why authors used the term adverse effects? Why not side effects?
Diarrhea and/or constipation are merely the extensions of the pharmacological effects of drugs which are mostly transient and resolve with time.

My concern is why to use adverse effects or adverse drug reaction.

Most likely , a short response from authors may highlight new avenues which could be another 'food of thought'
