    Default Concerta Update as of August 11, 2005

    Update as of July 1, 2005

    Further updates to be posted as they become available.

    The Federal Drug Administration in the U.S. is reviewing warnings on medications used in the treatment of ADHD.

    Concerta/Methylphenidate Adverse Events Not New or significant, Cmte. Says

    Concerns stem from adverse effects reported to the FDA in connection with psychiatric events like suicidal thoughts. It is not clear at this time though if the adverse effects are due to the medication or to the disorder.

    On another note, Columbia University Medical Center news release:

    Data Shows That ADHD Patients on CONCERTA(R) (Methylphenidate HCl) Are More Likely to Continue With Long-Term Therapy Than Those on Other Methylphenidate Drugs


    Janssen-Ortho is the manufacturer of Concerta in Canada. To read the (.pdf) Concerta product monograph, which is the product document approved by the Health Protection Branch (HPB) of Health Canada, Click Here

    Have you or a family member been prescribed Concerta, Adderall or Ritalin and what has been your experience in beneficial effects and/or adverse effects?

    Default Concerta Update as of August 11, 2005

    We have Concerta as an effective med in our household. Both y 13yr old and I use it and the benefits have been great.

    The into of this slow release (12hours) form of ritalin has not only created an environment where my son does not have to carry his next dose with him as with fast release but it is not a form of "ritalin" that is beneficial for those on the street... slow release doesn't give that instant gratification that those who abuse it crave.

    I'll certainly be following the studies. I know Adderall was pulled off the market and the Local TS expert here who handles the majority of our kids with TS/ADHD etc. personally called every one of her patients to ensure they discontinued use... it shows that doctors do really care.

    Default Concerta Update as of August 11, 2005

    Steve:

    I have copied this information and sent it to a friend that is having adverse reactions with her son taking Concerta. It appears in his case that he has become worse and more agitated. The boy is very active in two team sports activities 6 days a week. Lack of exercise or burning of energy does not apply.

    I have also contacted authorities to question concerta for my son which has ADHD, TS, ODD. By reading this a child should not take Concerta with a cocktail of disorders.

    Thank you for the updates and links to follow.

    Default Concerta Update as of August 11, 2005

    For most of what you read Ritalin and Concerta, which is ritalin in a 12 hour slow release form, are reported as a rx that should not be given to people with Tourette Syndrome.

    Some doctors believe that this warning comes from the fact that when taking Ritalin, some people have experienced increased tics. There is a belief that because Ritalin settles activity levels of the individual, that the tics are just more obvious ie were not noticed before because og the hyper activity.

    what are your thought?

    Default Concerta Update as of August 11, 2005

    My son is on slow release ritalin and also the fast release one. Some days his tics are very noticeable and other days not. His doctor also told me that sometimes ritalin does bring out the tics more.

    Default Concerta Update as of August 11, 2005

    Onset of tardive dyskinesia may emerge as neuroleptics are being reduced or discontinued. This pattern theoretically is related to denervation-hypersensitivity phenomenon. It appears with prolonged receptor blockade by a neuroleptic, the receptors rebound, becoming super sensitized. Medication noncompliance such as running out of a prescription or undergoing sudden drug withdrawals and resumptions are a common cause of this denervation-hypersensitivity rebound
    phenomenon.

    Some medications that are known to cause tardive syndromes include:

    Medications for gastrointestinal problems:
    metoclopramide (Reglan)
    prochlorperazine (Compazine)

    Medications for cough:
    promethazine (Phenergan)

    Medications for depression:
    amoxapine (Ascendin)
    perphenazine/amitriptyline (Triavil)

    Anti-psychotics or Neuroleptics:
    chlorpromazine (Thorazine)
    thioridazine (Mellaril)
    trifluoperazine (Stelazine)
    perphenazine (Trilafon)
    fluphenazine (Prolixin)
    thiothixene (Navane)
    haloperidol (Haldol)
    pimozide (Orap

    From what I have read there has been nothing indicating that Ritalin can cause such a side effect. Read more on Parkinson's
