Editor's Note: A number of readers responded strongly and negatively to this column, including some who have clearly used kratom and found it to be of benefit. BioNews respects and welcomes readers’ comments, including those that disagree with opinions expressed by its columnists. But it cannot and will not voice support for unapproved medications that are the subject of an FDA public health advisory (noting kratom’s use as an opioid alternative and to treat pain). We, and our writers, will continue to advise against any medication with “significant safety issues associated with its use.” If readers do choose to use such a medication, we recommend that they do so under medical guidance. If you visit Facebook groups for fibromyalgia or chronic pain, you probably see posts from warriors who use kratom for pain relief. I read so much about it online and considered it a potential option. But then I came across a warning from the Federal Drug Administration (FDA) in the United States issued Nov. 14, 2017. The FDA warns to consumers of “deadly risks” associated with the herb. The warning raises serious concerns about kratom and whether it is a safe alternative for relief of fibromyalgia symptoms.
