Up to recently Ritalin and other related drugs were considered panacea
for ADHD. Now we are finding out about serious side effects including
hallucination and suicide idealization.
Same goes for certain vaccinations for babies containing preservative thimerosal for other health problem such as measles and rubella etc. Now we are finding out that it is not without serious risks. Great caution is needed.
We are a profit driven society and sometimes at the cost of human life.
Following was an interesting report on ABC news tonight about ADHD
drugs.

FDA Probing ADHD Drugs for Side Effects
FDA Planning to Strengthen Warnings About Possible Psychiatric Side
Effects From ADHD Drugs
The Associated Press
WASHINGTON Jun 29, 2005 — The government is planning to strengthen
warnings about possible psychiatric side effects from Concerta and related
treatments for attention deficit hyperactivity, and is probing whether
other ADHD drugs need updating, too.
Concerta is a long-acting form of methylphenidate, sold generically and
under the brand name Ritalin. For years, those drugs' labels have
listed possible psychiatric side effects, such as agitation, psychosis or
transient depression.
But a routine Food and Drug Administration review of Concerta's use in
children turned up more reports of psychiatric reactions than
anticipated, including some that aren't explicitly labeled, such as suicidal
thoughts, hallucinations and violent behavior. A subsequent review of all
methylphenidate products found similar reports.
The FDA can't say if the drugs actually causes those side effects the
reports are from a database of reactions reported by medication users
that make such determinations very difficult.
But, in a statement posted on its Web site, the agency said it does
intend to strengthen the labeled warnings for all methylphenidate
products.
Currently, the drugs' labels may downplay the seriousness of
psychiatric side effects, and suggest they're only a risk in people who've
already experienced psychiatric disorders, wrote FDA drug safety evaluator
Kathleen Phelan.
Indeed, stimulant drugs "may exacerbate symptoms and reveal them for
the first time" in children with previously unrecognized psychiatric
illnesses, she wrote.
But, among 36 cases of psychiatric side effects in child Concerta
users, six report histories of psychiatric illness, three deny such
histories and there's no information on the rest, Phelan wrote. Further
investigation is needed to determine if such side effects may also occur in
people without underlying illness, she added.
FDA said it doesn't intend to change the drugs' labels right away. It
is investigating whether similar behaviors are seen with additional ADHD
treatments, such as Adderall and Strattera to avoid people switching
drugs over the concern "based on incomplete safety assessments," said an
FDA document prepared for a meeting of the agency's scientific advisers
on Thursday.

That probe should be finished early next year.
Concerta maker Johnson & Johnson declined immediate comment.
