Comments on a Food and Drug Administration survey on the status of useful written prescription drug information for patients, requesting that it be redesigned. (HRG Publication #1512)USEFUL WRITTEN PRESCRIPTION DRUG INFORMATION FOR PATIENTS Docket No. 00N-0352 Larry D. Sasich, Pharm.D., M.P.H., FASHP and February 29 March 1, 2000 The Evaluation of Written Prescription Information Provided in Community Pharmacies: An 8-State Survey (The Survey) is an interim study funded by the Food and Drug Administration (FDA) that was required by the 1996 Action Plan for the Provision of Useful Prescription Medicine Information(1) (Action Plan). The purpose of The Survey was to see how many prescription drug consumers are receiving patient information leaflets (PILs) and whether the unregulated PILs produced by commercial information vendors currently being distributed to consumers meet the Action Plan's definition of useful information. The Survey has failed to provide acceptable information to assess the adequacy of the PILs now being received by consumers and must be promptly redesigned in order to accurately measure the quality of this important information for consumers. By January 1, 2001, 75% of patients who get prescriptions filled are supposed to get patient information leaflets which contain information "consistent with or derived from FDA-approved" labeling for a drug. Despite the shortcomings of the FDA-funded Survey's design (see below), only 12.5 percent of the PILs distributed with the drug ibuprofen (Motrin) informed consumers of the drug's contraindications and what steps to take should the contraindications exist and only 5.3 percent of these PILs included specific precautions, their significance, and how consumers could avoid harm. Despite these worrisome findings, 82.6 percent of these PILs were graded as having high adherence to the Action Plan criterion for being scientifically accurate, that is, containing information "consistent with or derived from FDA-approved" labeling for a drug. We conducted an informal survey this month of the PILs being distributed for ibuprofen by four Washington DC pharmacies that included the chain pharmacies CVS and RiteAid with a combined total of over 7,900 stores between them. We found that the following critical, potentially life-saving information was not contained in these PILs: (1) that gastrointestinal (GI) perforation, ulceration, and bleeding are the most frequent serious adverse effects associated with the use of ibuprofen; and (2) that GI perforation, ulceration, and bleeding can lead to hospitalization that has resulted in death. If The Survey's methodology is followed in the subsequent survey that will be used by the Secretary of the Department of Health and Human Services to determine the quality of information contained in commercially prepared PILs, then adherence to the Action Plan guidelines will be overestimated. In our view, the greatest weakness of The Survey's methodology is in not accurately assessing if the information content of commercially prepared PILs is " consistent with or derived from FDA-approved labeling " for a drug. Because inadequate access to scientifically accurate drug information is a major cause of the inappropriate use of prescription drugs, resulting in serious personal injury to consumers and related costs to the healthcare system Public Citizen's Health Research Group strongly urges the following:
The Action Plan resulted from compromise federal legislation (P.L. 104-180)(2) passed after language was inserted in an FDA appropriations bill to prevent the agency from finalizing a 1995 proposed rule(3), a rule similar to the agency's 1979 proposal, to mandate the distribution of useful, scientifically accurate information to consumers with each new prescription by pharmacists. If the Action Plan's quality and quantity goals are not reached by January 1, 2001 the Secretary of the Department of Health and Human Services has the option, after the mandatory period for public comment, to implement the FDA's 1995 proposed rule or another plan to ensure consumer's access to written drug information. The process of "granting" consumers access to objective useful, scientifically accurate written drug information began in 1979 when the FDA proposed a rule to mandate the distribution of such information with new prescriptions for ten classes of drugs that would have encompassed approximately 350 products. Groups representing the private sector have irresponsibly misplaced their political dogma ahead of the public's health and have prevented consumer's access to useful drug information for over 20 years. Rather than viewing the distribution of useful drug information to consumers as safety and labeling issues, legally under the authority of the FDA, the private sector sees the mandatory distribution of useful information as an unwarranted intrusion on the professional autonomy of physicians and pharmacists and ignores the public need for objective drug information. THE SURVEY RESULTS Table 3 of The Survey is noteworthy as it highlights the fact that the unregulated PILs currently being distributed omit substantial risk information that is needed by consumers to make informed decisions to initially use or continue to use a prescription drug. The commercially prepared PILs consistently scored low on The Survey's Criterion 3 (identifies contraindications and what to do if the contraindications are present) and Criterion 4 (includes specific precautions, their significance, and how to avoid harm). For Criterion 3, the percentage of PILs that were classified as having high adherence to the Action Plan guidelines was reported as ibuprofen (12.5%), amoxicillin (31.0%), and paroxetine (21.1%). The percentage of PILs meeting the high adherence classification for Criterion 4 was reported as ibuprofen (5.3%), amoxicillin (73.5%), and paroxetine (15.8%). In view of the PILs lack of adherence to Criteria 3 and 4 it is remarkable, and contradictory, that the expert panel gave high marks for the commercial PILs on Criterion 9 (information is scientifically accurate and includes a disclaimer). The percentage of PILs classified as attaining high adherence to Criterion 9 was; ibuprofen (82.6%), amoxicillin (89.2%), and paroxetine (61.3%). The results reported for Criteria 3, 4, and 9 in Table 3 of The Survey suggest that the expert panel has misinterpreted the Action Plan's definition of scientifically accurate. Scientific accuracy, for the purposes of the Action Plan, not only includes that only FDA approved uses appear in PILs, but that risk information that appears in PILs be " consistent with or derived from FDA-approved labeling ."(4) Also defining useful consumer information is that the information is sufficiently specific and comprehensive. Included in this definition is: ...risk information should include enough detail for the consumer to understand the significance of the hazard described; for example, the information should allow consumers to distinguish between a warning about an improper use that could be life-threatening and one that could result in minor discomfort.(5) An examination of the Patient Information Evaluation Forms (PIEFs) used in The Survey indicate that they do not adequately assess consistency with the FDA-approved professional product labeling (scientific accuracy) of the commercially prepared information being distributed with the three study drugs. Before other factors are considered in the evaluation of the quality of written drug information for consumers, the scientific accuracy of the information must first be adequately assessed. Information that is understandable, legible and readily comprehensible by consumers that lacks scientific accuracy, though communicated well, is not useful information. In fact, it may be misleading and thus potentially dangerous. For example, if consumer information lacks scientifically accurate content about adverse drug reactions or drug interactions and the potential seriousness of these reactions, the information has not been placed in a context that is useful and could affect consumers' decisions to use, or to continue to use, the product. SURVEY OF PILS FOR IBUPROFEN BEING DISTRIBUTED IN FOUR WASHINGTON DC PHARMACIES Table 4 of The Survey is an analysis of the percentage of PILs with partial or full adherence to drug-specific sub-criteria for the PILs distributed with the study drug ibuprofen. Criterion 5 of the PIEF for the ibuprofen PILs is "Information includes enough detail for proper monitoring and interpretation of serious or frequently occurring adverse reactions." The first sub-criterion evaluated under Criterion 5 is if the ibuprofen PILs are sufficiently specific and comprehensive regarding the risk of gastrointestinal (GI) toxicity with ibuprofen: stop taking and call provider immediately if: severe GI effects occur, for ex., bleeding, ulceration, black or bloody stools; effects may result in hospitalization, may be fatal The Survey's expert panel found that 95.5 percent of PILs distributed with ibuprofen partially or fully adhered to the above sub-criterion. This result points to a major weakness in The Survey's methodology. If one of the elements assessed by this criterion is missing from a PIL, the PIL can not be classified as adhering to the Action Plan guideline for sufficiently specific and comprehensive information and thus cannot count as useful information. The national expert panel's scoring partial adherence is therefore invalid in assessing if an ibuprofen PIL is sufficiently specific and comprehensive to be considered to be useful information. Our skepticism of this result led us to survey the ibuprofen PILs being distributed by a convenience sample of four pharmacies in Washington DC. Using the FDA-approved professional product labeling for ibuprofen and the Action Plan guideline that useful information is sufficiently specific and comprehensive for consumers we evaluated the content of the PILs obtained from the four Washington DC pharmacies for the four following elements:
Our results appear in Table 1 below. The name of the pharmacy, the date we obtained an ibuprofen PIL, and the name of the commercial information vendor, if known, is listed in column one. Column two lists which of the above four elements were missing from the PILs we obtained. The PILs we obtained from the four pharmacies appear as Appendices 1 through 4 at the end of these comments. None of the four PILs informed consumers that GI toxicity is the most serious adverse effect associated with the use of ibuprofen and that GI toxicity can lead to hospitalization and death. This type of risk information is essential for consumers to make informed decisions about their drug therapy.
THE ADEQUACY OF THE PIEFs USED IN THE SURVEY The PIEFs developed by the national expert panel, in a number of instances, fail to adequately assess the information content of the PILs in comparison to the FDA-approved professional product labeling for the three study drugs ibuprofen, amoxicillin, and paroxetine. The Action Plan lists 11 components of useful written drug information for consumers. These are discussed on page 20 of the Action Plan and are meant as a "floor" for defining written prescription drug information as sufficiently specific and comprehensive for consumers. The three tables below, one for each study drug, summarize information required in the Action Plan that was incorrectly assessed or omitted in the PIEFs developed by the national expert panel. These tables were constructed by first preparing additional tables for each study drug and categorizing the information contained in the drug's approved product labeling according to the 11 components of useful information defined in the Action Plan. Only the Action Plan components where information was incorrectly assessed or omitted from evaluation by a PIEF are listed in the following tables along with the information from the drug's FDA-approved labeling that should have been assessed by the PIEF. The tables constructed from the FDA-approved product labeling for the three study drugs are listed as Appendices 5, 6 and 7 at the end of these comments. IBUPROFEN(6) The PIEF used to evaluate the ibuprofen PILs failed to assess an off-label use for the drug. Use of the drug in pediatric populations was not assessed, a serious contraindication was omitted, as were important precautions, including drug interactions, and frequently occurring adverse drug reactions.
AMOXICILLIN The professional product labeling for the study drug amoxicillin(7) carries two bolded warnings. The first regarding, " SERIOUS AND OCCASIONALLY FATAL HYPERSENSITIVITY (ANAPHYLACTIC) REACTIONS " and the second that "Pseudomembranous colitis [inflammation of the intestines] has been reported with nearly all antibacterial agents, including amoxicillin, and may range in severity from mild to life-threatening." The PIEF for the amoxicillin PILs does evaluate if consumers are informed to stop taking the drug and call the doctor immediately if severe skin rash, hives, itching, or difficulty breathing or swallowing occur (these are symptoms of a potentially life-threatening allergic reaction) or if severe diarrhea or cramps are experienced (these are the symptoms of a potentially life-threatening inflammation of the intestine). However, the PIEF does not evaluate if consumers are informed that these are symptoms of life-threatening adverse drug reactions. The PIEF developed by the national expert panel for amoxicillin omitted the evaluation of two important precautions and three potentially serious adverse drug reactions.
PAROXITENE The professional product labeling for paroxetine carries a bold warning concerning the possibility of serious, sometimes fatal reactions when a selective serotonin reuptake inhibitor (SSRI) antidepressant similar to paroxetine is taken in combination with monoamine oxidase inhibitors (MAOIs) or within 14 days of discontinuing treatment with a MAOI.(8) The Action Plan's components of useful information contain the guideline: ...a statement of precaution regarding any circumstances in which the use of the medicine could lead to serious injury or death.(9) The PIEF developed for the Paroxetine PIL does not evaluate if the life-threatening nature of the possible interaction between paroxetine and MAOIs is contained in the information being distributed to consumers. Omission of this information does not " allow consumers to distinguish between a warning about an improper use that could be life-threatening and one that could result in minor discomfort." The expert panel's PIEF used to evaluate paroxetine PILs omitted evaluation of one FDA-approved use for the drug and one contraindication for using the drug. In addition, this PIEF did not evaluate the content of paroxetine PILs for 14 precautions, including drug interactions, and omitted evaluating 25 frequently occurring adverse drug reactions.

ENDNOTES 1. Action Plan for the Provision of Useful Prescription Medicine Information presented to The Honorable Donna E. Shalala, Secretary of the Department of Health and Human Services by the Steering Committee for the Collaborative Development of a Long-Range Actions Plan for the Provision of Useful Prescription Medicine Information, December 1996. A Steering Committee met seven times between September 18, 1996 and December 4, 1996 in the Washington DC area in a very contentious debate to develop The Action Plan. Consumer groups advocated for the mandatory distribution by pharmacists of FDA regulated drug information similar to regulations first proposed by the agency in 1979. Consumer groups noted that the private sector had pursued a failed paradigm since the inception of the National Council on Patient Information and Education (NCPIE) in 1982 that has not provided useful information to prescription drug consumers. Entities representing the drug industry, pharmacy and medicine, and commercial information vendors pressed for the status quo voluntary distribution, voluntary quality standards, no oversight, and no FDA involvement. 2.
