Hi MJW, thanks so much for the links. I found the info below on that forum answered by Dr. Hale and he seems to be contradicting things slightly as he states that infants don't typically get Reyes syndrome and the amount of meselemine in mother's milk shouldn't be enough to pose a risk. I am still unsure what I should be doing as I MUST bfed AND take my meds...ugh... I have reduced slightly to 10 pills(down from 12) a day, but am still over his suggested limit. Still causing me some concerns...
Reye's syndrome and its relationship to aspirin is somewhat enigmatic. We do know that aspirin use during a fever, flu, or varicella viral syndrome may dramatically increase the risk of Reye's syndrome. Aspirin is certainly metabolized to salicylic acid, but to be honest with you, we don't know for sure if salicylic acid products (Asacol, Pepto Bismol, etc) are associated with Reye's Syndrome. I ran across a good review of this issue and there still remains some confusion over this relationship (see http://fr.cos.com/cgi-bin/getRec?id=20030417a147).
But to answer your question, exactly, I do not think the use of salicylates during the first three weeks postnatally pose any greater risk of Reye's than at any other time. But if the infant is suffering from a viral infection, then I would be more uncomfortable, even with the salicylcates. Reye's syndrome virtually ALWAYS requires a viral infection at the same time as exposure to aspirin (or perhaps non-acetylated salicylates). If there is no viral infection, then I think the risk of salicylates is minimal.
Interestingly, if you look at the incidence of Reye's syndrome, virtually all of the cases occured in older children (10-15 yrs)...not infants. Perhaps infants are less sensitive.
But to be clear. I do not know with certainty that non-acetylated salicylates will cause Reye's syndrome, so I cannot tell you with certainty that their use early postnatally during an RSV season is safe.
Lastly, I've asked several Reye's experts about the dose-response relationship of Reye's and salicylates, and no one seems to know if these infants have to have a direct and clinical oral dose, or if the miniscule levels in milk would even be a risk factor at all. All the cases thus far reported were from DIRECT administration of acetylsalicylic acid and some possibly from salicylic acid products....none from breast milk containing these drugs.
I'm sorry, but this area is confusing. If anyone out there knows a lot about this area...please phone me...as I've asked many to no avail.
