Tylenol consumption linked to asthma.
Researchers at Kings College in London, England
have discovered a correlation between the consumption of Tylenol (acetaminophen, paracetamol) and the
incidence of allergic diseases. They compared acetaminophen sales in 36 countries with the incidence of
asthma, rhinitis, wheeze, and other allergic diseases and concluded that countries with higher sales of
acetaminophen (Australia, Canada, New Zealand, Ireland, the USA, and the UK) had a greater prevalence
of these diseases. The researchers believe that acetaminophen reduces glutathione levels and thereby
impairs antioxidant defenses and promotes allergic inflammation. They caution that further studies are
needed to confirm the connection.
