American Academy of Pediatrics Guidelines for Treating Behavioral
Disorders in Children with Ritalin Ignores Evidence of Cancer Risks
warns Samuel S. Epstein, M.D.

Chicago, 10/04/01. Based on an industry-funded multi-university trial
on
282 pre-teen children treated with Ritalin for attention
deficit/hyperactivity disorders (ADHD), just published in Pediatrics,
the American Academy of Pediatrics has endorsed the use of the drug.
However, the Academy ignores clear evidence of the drug's cancer risks
of which parents, teachers and school nurses, besides most
pediatricians
and psychiatrists, still remain uninformed and unaware.

Some 40 years after the drug was first marketed by Ciba Geigy,
carcinogenicity tests were conducted at the taxpayers expense by the
National Toxicology Program, the results of which were published in
1995. Adult mice were fed Ritalin over a two-year period at dosages
close to those prescribed to children. The mice developed a
statistically significant incidence of liver abnormalities and tumors,
including highly aggressive rare cancers known as hepatoblastomas.
These
findings are particularly disturbing as the tests were conducted on
adult, rather than young mice which would be expected to be much more
sensitive to carcinogenic effects. The National Toxicology Program
concluded that Ritalin is a "possible human carcinogen," and
recommended
the need for further research. While still insisting that the drug is
safe, the Food and Drug Administration admitted that these findings
signal "carcinogenic potential," and required a statement to this
effect
in the drug's package insert. However, these inserts are not seen by
parents or nurses.

The Physicians' Desk Reference admits evidence on the carcinogenicity
of
Ritalin, now manufactured by Novartis, qualified by the statement that
"the significance of these results is unknown," apparently not
recognizing that this is more alarming than re***uring. Apart from
cancer risks, there is also suggestive evidence that Ritalin induces
genetic damage in blood cells of Ritalin-treated children.

Concerns on Ritalin's cancer risk are more acute in view of the
millions
of children treated annually with the drug and the escalating incidence

of childhood cancer, by some 35% over the last few decades, quite apart

from delayed risks of cancer in adult life. These risks are compounded
by the availability of alternative safe and effective procedures,
notably behavior modification and biofeedback.

There is no justification for prescribing Ritalin, even by highly
qualified pediatricians and psychiatrists, unless parents have been
explicitly informed of the drug's cancer risks. Otherwise, prescribing
Ritalin constitutes unarguable medical malpractice.

wow, very frightening and very relevant for anyone taking ritalin.

Thanks for your comment Jeff but I suspect there are still some out
there who are not aware of the carcinogenicity of Ritalin.

Like you, for example. I could only find two studies on the subject,
both in rats or mice. The conclusion was that there was little
evidence of carcinogenicity from methylphenidate,and in some cases it
actually seemed to *reduce* the instance of tumors.

"a little evidence of carcinogenicity" is enough for me.

That's not what he said, idiot. And, if you're concerned by this level of
risk, you lead a terribly frightened existence. Kill yourself before you
are taken by the toxic world that surrounds you. How did you survive this
long?

According to this, the dose was 30 times higher than the maximum dose, based
on the weight of the mice.

There is no evidence that this occurs in humans.
