[Harp-L] Subject: Re: Adverse reactions to denture cleansers?

[EGS1217@xxxxxxx]

Some people have mentioned routinely using denture tablets to clean their  
harmonicas.  I just got this alert from an FDA mailing. I'm not sure how it  
would impact a harmonica player if the harp is thoroughly rinsed afterwards, but  
here's the info fwiw:

"FDA notified dental healthcare  professionals and patients of the risk of 
serious allergic reactions in users of  denture cleansers. These adverse events, 
including abdominal pain, vomiting,  seizures, hypotension and difficulty 
breathing, have occurred both when the  product has been used properly as well as 
from improper use. These events can  occur soon after first use or after 
years of use. FDA believes that the  ingredient responsible for these reactions is 
persulfate, a known allergen.  Persulfates are used in most denture cleansers 
to help clean and bleach the  dentures. FDA has provided specific 
recommendations for dental healthcare  professionals and an 'Advice for Patients' 
document. 

FDA is recommending  that all manufacturers of denture cleansers modify their 
labeling to include  warning information that the product contains 
persulfates and recommends  improving the directions for use on their labeling in order 
to reduce  misuse.
