MYTHS, LIES, MISUNDERSTANDINGS--AND FACTS--ABOUT RITALIN
By Joe Parsons There has been a huge volume of misinformation about attention deficit disorder and its treatment. Much of this information is clearly agenda driven, coming from sources that have products to sell ("All-Natural Alternatives to Ritalin") or some other hidden agenda, while some comes from a simple lack of information. Most of these statements concern the most familiar pharmacological treatment for ADHD, Ritalin (methylphenidate hydrochloride). While much of the misinformation is obviously false, some of it often sounds reasonable. Here are some of the common myths, lies and misunderstandings about Ritalin--along with the facts. As always, the many knowledgeable participants in alt.support.attn-deficit are happy to enter into *rational* discussions of these and other issues surrounding ADHD. This do***ent may not be reprinted, reposted or distributed without the express ©2000, Joe Parsons jmp@cyber-mall.com MYTH: The production of Ritalin has increased by 700% since 1990. Therefore, it is overprescibed. FACT: Since methylphenidate is subject to annual production quotas imposed by the Drug Enforcement Administration (DEA), the quantities manufactured and sold are a matter of public record, under FOIA. In 1990, the quota was 1776 kg, rising to 14,957 kg in 1999 and 2000. The Annual Production Quota (APQ) showed sharp increases from 1993-1995 (increases of 25.8%, 38.9% and 21.3% respectively), but began to level; APQ for 1996-1999 showed increases of 11.6%, 14.8%, 4.2% and 3.4%, respectively. The APQ from 1999 to 2000 was unchanged. Apart from the fact that the production of methylphenidate has increased dramatically during the last decade, concluding from that fact that the drug is overprescibed exemplifies an logical fallacy called "hasty generalization." It is a fallacy because there can be *other* reasons for the increased production, among them being heightened public awareness of the condition and improved diagnostic process. In order for someone to defend the assertion that methylphenidate is overprescibed, they would have to know the following: 1) How many people received prescriptions for Ritalin; 2) How many of those people should NOT have received the drug; 3) How many people SHOULD have received the drug, but did not. Since at least two of these components are difficult (if not impossible) to ascertain, any assertion regarding the supposed over- (or under-) prescription of the medication is essentially indefensible. MYTH: There are over 10 million children taking Ritalin. FACT: There may be 10 million *prescriptions* written annually. Some make the erroneous inference that this number equates to 10 million *people* taking the drug. It is erroneous because Ritalin, being a Schedule II substance, requires a new prescription each month. If each patient received a new prescription every month, 10 million prescriptions would equate to 833,000 patients. Since some prescriptions *may* last for longer than a month, and since some people do not take the drug during the entire year, the actual number of patients is higher. The Washington State University College of Pharmacy completed a peer-reviewed study in 1999 indicating that for the year 1995, 1,461,867 children aged 5-18 were taking methylphenidate. MYTH: Ritalin is an addictive drug. That's why the FDA has made it a Type 2 Narcotic. FACT: Under the Federal Controlled Substances Act of 1970, The Drug Enforcement Administration (an arm of the Department of Justice)--not the FDA--has designated certain drugs, methylphenidate (Ritalin) among them, as "Schedule 2 Controlled Substances." This means that three criteria must be met in the judgment of the DEA: 1) The drug must have a high potential for abuse; 2) The drug must have a legitimate, recognized medical use; 3) Abuse of the drug may lead to severe psychological or physical dependence The text of the Act is at http://www.mninter.net/~publish/csa2.htm As a division of the Department of Justice, DEA is a *law enforcement* organization, and as such is concerned primarily with the abuse *potential* of substances. The fact that this potential does exist is not an indictment of the appropriateness or safety of Ritalin (or other medications) for treating ADHD. The Brookhaven National Laboratory (a division of the U.S. Department of Energy) published a paper on the subject of addiction and methylphenidate: UPTON, NY - New research on Ritalin, a drug prescribed to millions of American children with Attention Deficit Hyperactivity Disorder (ADHD), indicates that it is safe if taken in pill form for that the****utic purpose. That finding will be reported in the October issue of the American Journal of Psychiatry by scientists from the U.S. Department of Energy's Brookhaven National Laboratory and the State University of New York at Stony Brook. The paper can be found at http://www.pubaf.bnl.gov/pr/bnlpr092998.html Methylphenidate is not a narcotic; as a central nervous system stimulant, it is actually on the opposite end of the spectrum from a narcotic. MYTH: People always build a tolerance to Ritalin; that's why they have to take more and more. FACT: The appropriate dosage is typically determined by a process called "titration;" the patient begins at a very small dose, increasing it incrementally every few days, until the desired result is achieved. The the****utic dosage seems to be independent of body weight; a 70 pound child might take 20 mg three times a day, while a 200 pound adult might experience relief of symptoms at 5 mg twice a day. There is no evidence that a patient develops tolerance to Ritalin, but for some, the required the****utic dosage may change over time. For many, the dosage remains static. In those cases where a patient finds his or her the****utic dosage increasing, changing to a different stimulant (Dexedrine, Adderall, Desoxyn or Cylert) is often preferable to increasing the dosage. MYTH: Ritalin always has a "rebound" (withdrawal) effect when the drug is withdrawn. FACT: Some people do experience "rebound" as their last dose wears off: their symptoms may return for a time in more severe form, together with possible irritability and anxiety. This effect is not universal, but when it does occur, it can be managed by taking a smaller dose as the last dose of the day, by adding an antidepressant like Wellbutrin or Effexor, or by switching to a different stimulant, like Dexedrine or Adderall. MYTH: Ritalin is overprescibed; over 11 million children are addicted to it, and the number is growing rapidly. Since methylphenidate is a Controlled Substance, the DEA imposes quotas on its production. These quota figures are public, and based on the most recent production figures, it appears that there are approximately 2.5 million individuals of all ages taking the medication. The University of Washington School of Pharmacy has recently completed a six-year study on the diagnosis of ADHD and the prescription of stimulants for children between the ages of 5 and 18. The results were published in the peer-reviewed "Journal of Pediatrics" in March, 1999. According to this study, there are 2.04 million children receiving stimulants for ADHD, and the incidence of prescription has decreased slightly during the last three years. MYTH: Ritalin is a chemical strait jacket, used to turn normal, spirited kids into compliant zombies. FACT: Two of the core symptoms of ADHD are impulsivity and distractibility. These two traits are closely tied to the brain's production and use of the neurotransmitter, dopamine; many practitioners and researchers believe that underproduction (or underutilization) of this chemical is a major culprit in the cause of ADHD. Stimulants like Ritalin, Dexedrine, Adderall and others work either by increasing the amount of available dopamine or by allowing it to be utilized more efficiently. A person taking the correct dosage will be better able to "filter out" distractions and to learn a "reflective pause" before speaking or acting impulsively. Neurotypical people possess these "filtering" and "reflective pause" mechanisms to a greater extent than people who meet the criteria for ADHD. Stimulant medication can assist the patient in learning to manage her own behavior and attention--not force her to behave in a certain way. MYTH: Ritalin changes one's personality. FACT: Stimulant medication, as used in treating and managing ADHD, helps the ADHD person develop appropriate coping strategies and to learn to manage his own behavior. A stimulant will improve the patient's ability to recover from distractions and to manage impulsivity. It has no effect on that person's personality--who that person is. MYTH: Ritalin is always used as a "quick fix" by parents and teachers too lazy to do their jobs. FACT: For most parents, the decision to incorporate medication into the treatment plan for their children is a difficult one, and is not entered into frivolously. A proper diagnosis is arrived at only after eliminating other factors, such as allergies, family stressors and other medical conditions. The initial testing and diagnosis may be accomplished by a psychologist who specializes in ADHD, but in those cases where medication is appropriate, only a medical doctor is permitted to prescribe. By law, teachers and school administrators are prohibited from insisting that a child take medication as a condition of instruction. They are not allowed to "diagnose" a child. What they ARE allowed to do is to confer with the parents or guardians and to recommend evaluation by the appropriate practitioner. MYTH: Ritalin stunts growth FACT: There is no evidence to substantiate this. A common side effect of stimulant medication is appetite suppression; some may have concluded that this appetite suppression MUST lead to reduced stature in adulthood. Current thinking indicates that the growth cycle of ADHD people may be on a different time frame than for others. Joseph Biederman, M.D. (Massachusetts General Hospital) discusses these issues in "The Journal of the American Academy of Child Adolescent Psychiatry 1996 Nov;35(11):1460-9: Http://x28.deja.com/getdoc.xp?AN=441833002 MYTH: Ritalin causes cancer FACT: A research study was done by the National Institute of Health (NIH) under the aegis of the FDA, and the results of that study were published on January 12, 1996. In this two-year study by the National Toxicology Program, rats and mice were given methylphenidate, with the following results: The [FDA]continues to regard Ritalin as a safe and effective drug. The study in rats revealed no cancer-causing activity. The findings in mice included increased rates of a non-cancerous liver tumor (hepatocellular adenomas) and, in males only, the occurrence of malignant liver tumor (hepatoblastomas). The positive findings were seen in one species of rodent (the mouse) and in only one organ -- the liver - which is known to be particularly likely to develop tumors to a wide variety of stimuli. -- The increased rates were seen primarily in non-malignant tumors. -- There was no increase in mortality associated with the tumors. The entire text of the letter is at the FDA website: Http://www.fda.gov//bbs/topics/ANSWERS/ANS00705.html The study itself is at http://ntp-server.niehs.nih.gov/htdocs/LT-studies/tr439.html MYTH: Ritalin is an untested, dangerous drug whose effects are not at all understood FACT: Methylphenidate was first synthesized in Europe in 1944, with the objective of producing a non-addictive stimulant. It was introduced to the U.S. in 1955 and approved by the FDA for the treatment of drug-induced lethargy, mild depression and narcolepsy. The Swiss company, Ciba-Geigy, began marketing it in the 1960s, primarily as a way to improve the failing memory of geriatric patients--and for hyperactivity in children. To date, there have been no reported instances of mortality or of damage resulting from the the****utic use of methylphenidate. [NOTE: While this statement was correct as of its initial writing, there has been one death reported where Ritalin was implicated. On March 21, 2000, Matthew Smith, 14, of Clawson, Michigan collapsed and died of heart failure. The Oakland County, Michigan medical examiner, Dr. Ljubisa Dragovic, reported that the cause of Matthew Smith's death was "long term use of methylphenidate." Matthew Smith had taken methylphenidate for ADHD for approximately 8 years. Several reports mention that he had complained in previous years of "chest pains and racing heartbeat," but the drug was not discontinued. There remains controversy among other physicians concerning Dr. Dragovic's finding.] The mechanism by which methylphenidate operates is not *completely* understood, but the same can be said of many other useful drugs--like aspirin. To say (or infer) that it is a complete mystery, however, is inaccurate and misleading. Methylphenidate works by stimulating that area of the brain that appears to be less active in ADHD persons than in neurotypicals. This stimulation results in increased production and improved utilization of the neurotransmitter, dopamine, and to a lesser extent, serotonin. Dopamine is believed to be responsible for attention, impulsivity and motor activity. MYTH: The powerful ADD advocacy group, CHADD (Children and Adults with ADD) is bankrolled by Ciba-Geigy, the manufacturer of Ritalin. The Swiss pharmaceutical giant gave the money to CHADD in exchange for CHADD's mobilizing its members to petitioning the DEA about slackening the stringent controls on Ritalin. This financial backing was kept secret from the members until it was exposed on a television program. FACT: CHADD has received financial support from Ciba-Geigy (now Novartis Pharmaceuticals, Inc.). The advocacy group was incorporated in 1987 as a nonprofit corporation under S.501(c)(3) of the Internal Revenue Code. CHADD sought financial support from a number of corporations, Ciba-Geigy among them. In the seven years between 1987-1994, CHADD received approximately $813,000 in cash grants. The annual budget of the organization is in excess of $2 million. In order for CHADD to be granted and to retain tax exempt status, its financial statements MUST, as a matter of law, be of public record--including any contributions from corporate donors. Therefore, no one can reasonably claim that the donations were "secret." With regard to the petition to ease the controls on Ritalin, many people--doctors and patients alike--find the additional paperwork and bureaucracy to be burdensome. Because (in most states) prescriptions for Schedule II substances like Ritalin can be issued for no more than a 30 day supply and cannot be refilled or phoned into the pharmacy, a doctor's visit is required for each month's prescription.
