Invisalign Invisible Braces Linked to Reports of Serious Allergic Reactions

Federal investigators have issued a warning to the makers of Invisalign for a failure to notify the FDA about potential problems with their invisible braces, which have reportedly caused some users to suffer extreme allergic reactions. 

The FDA Invisalign “invisible braces” warning letter was issued last month and accuses Align Technology, Inc. of failing to pass on adverse event reports to the agency in a timely manner. Some of the complaints, which include incidents of severe allergic reactions that have required hospitalization in some cases, date back to November 2007, but were not reported to the FDA as required by law.

According to the warning letter, allergic reactions to Invisalign braces reported by users include swollen and irritated lips, sore throats, a burning sensation on the tongue, ulcerations in the mouth and swollen lymph nodes. In some instances Invisalign side effects led consumers to stop using the braces.

Federal regulations require medical device and drug companies who receive consumer complaints regarding potential side effects of their products to forward those adverse event reports on to FDA within 30 calendar days of receiving them or otherwise becoming aware of the incident.

In a response to the letter, Align Technology said in a press release that it was attempting to fully comply with the FDA’s concerns, that they are turning over all copies of documentation requested by the agency and that they want to resolve the issue “with minimal impact on the company.”

Align Technology claims that the Invisalign system has been used by more than 1.3 million people since it received FDA approval in 1998. The product line includes Invisalign, Invisalign Teen, Invisalign Assist, Invisalign Express and Vivera Retainers. It was not clear from the warning letter which Invisalign products were associated with the reported problems and which were not.

    I posted a comment at 19th july 2016 about my nightmare with invisalign retainers. I had also a hard time getting an innofensive report about the symptoms I had when using the product. Finally I was given hypoalergenic retainers in the 5th of December.I falled immediatly in bed with flu ( coincidence) and at the second week my face was a furnace of skin rashes , swoolen eyes, itchy neck and fever.Conclusion: The hypoallergenic retainers are also heavily toxic.
