Yes, it is an FDA approved drug, but the way it has been prescribed for those of us on this website is outrageous, and that does not mean we have no recourse. I would urge anyone who so desires to file a report with the FDA, which I just did. It took awhile to write all the details, but one can "save and exit" the report in order to continue it later.
This is the emailed response I just received: Thank you for submitting your report to MedWatch, the FDA Safety Information and Adverse Event Reporting Program.
This acknowledgment confirms that your report was received. Reports are added to a post marketing safety database with similar reports and reviewed by the FDA's post marketing safety staff. Voluntary reports are essential for ensuring the continued safety of FDA-regulated products. One or two well documented case reports may provide an early signal of unexpected problems and lead to additional evaluation. This may result in FDA regulatory actions that improve the safety of the products used in patient care each day.
