The U.S. Food and Drug Administration announced on January 29 that non-cirrhotic portal hypertension, a rare, but serious, liver disorder, has been reported in some HIV patients taking Videx/Videx EC (didanosine).
Videx is an antiretroviral medicine first approved by the FDA in 1991. Videx EC is a delayed-release version of Videx approved in 2000. Videx/Videx EC is used in combination with other antiretroviral medicines to treat HIV infection in children and adults.
During an 18-year period, 42 cases of non-cirrhotic portal hypertension were reported to the FDA’s Adverse Event Reporting System for patients taking Videx/Videx EC. Four patients died from bleeding or liver failure after developing the condition.
Non-cirrhotic portal hypertension occurs when blood flow in the portal vein – a major vein in the liver – slows down and leads to severely enlarged veins in the esophagus. These enlarged veins, called esophageal varices, are thin and can break open, resulting in serious, and potentially fatal, bleeding.
The Videx and Videx EC product labels have been revised to help ensure that health care professionals and patients are aware of the risk and the signs and symptoms of non-cirrhotic portal hypertension.
The FDA evaluation concluded that the clinical benefits of Videx/Videx EC in certain patients with HIV continue to outweigh potential safety risks. Videx/Videx EC does not cure HIV infection, may not prevent development of HIV-related illnesses, and may not prevent the spread of HIV to other people.
Videx/Videx EC is marketed by Princeton, N.J.-based Bristol-Myers Squibb.

FDA Warns About Stolen Insulin
The U.S. Food and Drug Administration is reminding the public that stolen vials of the long-acting insulin Levemir made by Novo Nordisk Inc. still may be on the market.
Evidence gathered to date suggests that the stolen insulin was not stored and handled properly and may be dangerous for people to use. The FDA has received multiple reports of patients who suffered an adverse event due to poor control of glucose levels after using a vial from one of the stolen lots.
When the FDA first alerted the public to the theft in June, it reported that three lots of Levemir totaling 129,000 vials had been stolen in North Carolina. So far only about 2 percent of the total amount stolen has been recovered.
The FDA continues to aggressively investigate this matter and is asking for the public's help in reporting any information regarding these vials to the FDA's Office of Criminal Investigations (OCI) by calling 800-551-3989 or by visiting the OCI Web site.
The agency is advising patients who use Levemir insulin to:
1. Check your personal supply of insulin to determine if you have Levemir insulin from one of the following lots: XZF0036; XZF0037; XZF0038. You can locate the lot number on the side of the box of insulin and also on the side of the vial.
2. Do not use your Levemir insulin if it is from one of these lots. Replace it with a vial of Levemir insulin from another lot. If you must switch to another brand of insulin for any reason, first contact your health care provider because another insulin product may require adjustments in dosing.
3. Always look at your insulin carefully before using it. Levemir is a clear and colorless solution.

FDA Issues Early Communication about Ongoing Safety Review of Weight Loss Drug Orlistat
The U.S. Food and Drug Administration announced yesterday that it is reviewing adverse event reports of liver injury in patients taking the weight loss drug orlistat, marketed as the prescription drug Xenical and the over-the-counter medication Alli.
Between 1999 and 2008, the FDA received 32 reports of serious liver injury in patients taking orlistat. Of those cases, 27 reported hospitalization and six resulted in liver failure. Thirty of the adverse events occurred outside the United States. The most commonly reported adverse events included yellowing of the skin or whites of the eyes (jaundice), weakness, and stomach pain.
The FDA is reviewing additional data submitted by orlistat manufacturers on suspected cases of liver injury, and the issue has been discussed at the FDA’s Center for Drug Evaluation and Research Drug Safety Oversight Board.
“The issues here are complex, but FDA has benefited from the input of the Board, including comments from representatives from three FDA Centers and several other Agencies in the Department of Health and Human Services,” said Steven Osborne, M.D., executive director of the Board.
The FDA’s analysis of these data is ongoing, and no definite association between liver injury and orlistat has been established at this time. Consumers taking Xenical should continue to take it as prescribed, and those using over-the-counter Alli should continue to use the product as directed.
Full text of the Early Communication about an Ongoing Safety Review can be found here. The Early Communication is a risk communication tool used by the FDA to inform the public about its ongoing safety reviews of drugs. The FDA will release its findings on orlistat as soon as the review is completed.
Consumers who have used orlistat should consult a health care professional if they experience symptoms possibly associated with development of liver injury, particularly weakness or fatigue, fever, jaundice, or brown urine. Other symptoms may include abdominal pain, nausea, vomiting, light-colored stools, itching, or loss of appetite.
The FDA urges both health care professionals and consumers to report suspected side effects from the use of orlistat to FDA's MedWatch Adverse Event Reporting program either online, or by regular mail, fax, or phone.
-- Online

FDA Proposes Mandatory Electronic Safety Reporting
The U.S. Food and Drug Administration is proposing to amend postmarket safety reporting regulations for three of its centers to require that manufacturers and other facilities subject to current reporting requirements submit their reports in an electronic format.
The agency issued two proposed rules today—one that applies to electronic medical device adverse event reporting and one that applies to electronic drug and biologic product adverse experience reporting. Today’s rules would not change what types of incidents are required to be reported to the FDA—it would require that the incidents be reported in an electronic format that the FDA can process, review and archive.
“Both proposed rules will improve the agency’s ability to obtain safety information more quickly, which will help lead to faster identification of potential safety problems,” said David Buckles, Ph.D., director of the Division of Postmarket Surveillance at the FDA’s Center for Devices and Radiological Health (CDRH). “Information obtained from these reports may be critical to future action that improves patient safety.”
Currently, CDRH receives most mandatory medical device adverse event reports on paper, which requires that reports are manually entered into the center’s adverse event database, called the Manufacturer and User Facility Device Experience (MAUDE) database, for further analysis. Not only is this step costly, but it hinders CDRH’s ability to review safety data quickly to uncover potential public health problems.
The proposed regulation for medical devices would require manufacturers, importers and user facilities to submit reports to the FDA in electronic format, which will be loaded into the MAUDE database.
The electronic medical device reporting system, known as eMDR, provides a choice of two electronic options for reporting postmarket safety information. Small manufacturers with a limited number of reports may prefer an application known as eSub, which runs on free software available from the FDA. Large manufacturers, which can submit hundreds of reports per year, may prefer to use a batch submission protocol, based on a widely recognized informatics standard.
The FDA’s Center for Drug Evaluation and Research (CDER) and Center for Biologics Evaluation and Research (CBER) currently receive adverse event reports on paper forms or electronically. Safety reporting data submitted on paper forms must be manually entered into the FDA’s Adverse Event Reporting System (AERS) before these data can be evaluated. Since 2000, CDER and CBER have allowed manufacturers (through a pilot program and FDA guidance) to submit adverse event reports electronically, which get quickly entered into AERS. This pilot program has enabled FDA staff to more rapidly review postmarketing safety data and identify emerging safety problems. Safety reports in electronic format can currently be submitted to the FDA either through the FDA’s Electronic Submission Gateway or on CD-ROM, digital tape, or floppy disk. International Conference on Harmonization (ICH) standards for data elements and technical specifications are used for these electronic submissions.
The proposed rule for drugs and biologics reporting would require manufacturers, packers and distributors to submit reports to the FDA in electronic format, which will eliminate manual processing of paper forms by both manufacturers and the FDA. Reports will be submitted to the FDA using either the ICH electronic standards or through an FDA safety reporting Web portal that is currently under development.
“Electronic reporting of serious and unexpected adverse experiences will reduce industry costs and encourage better communication with the FDA and other regulators,” said Gerald J. Dal Pan, M.D., director of CDER’s Office of Surveillance and Epidemiology.
The proposed rule for drugs and biologics reporting does not apply to safety reports filed under an investigational new drug application, annual reports that manufacturers submit to the FDA on approved drugs and biologics, biologic product deviation reports, reports of complications of blood transfusion and collection confirmed to be fatal, and certain reports on human cells, tissues and cellular and tissue-based products.
The proposed rule for medical devices does not apply to reports submitted on a voluntary basis.
Manufacturers submitting reports under either rule would be required to obtain an electronic certificate to use the FDA Electronic Submissions Gateway. Information on how to prepare and send postmarket safety reports for devices and for drugs and biologics is contained in draft guidance documents. Draft guidance for device reports is available today—draft guidance for drug and biological product reports has been available since June 2008.

FDA Warns Consumers Not to Use Body Building Products Marketed as Containing Steroids or Steroid-Like Substances
The U.S. Food and Drug Administration today issued a Public Health Advisory (PHA) warning consumers to stop using body building products that are represented as containing steroids or steroid-like substances. Many of these products are marketed as dietary supplements.
The agency also issued a Warning Letter to American Cellular Laboratories Inc. for marketing and distributing body building products containing synthetic steroid substances. Although these products are marketed as dietary supplements, they are not dietary supplements, but instead are unapproved and misbranded drugs.
The PHA notifies consumers and health care professionals that the FDA has received reports of serious adverse events associated with the use of body building products that claim to contain steroids or steroid-like substances. Those adverse events include cases of serious liver injury, stroke, kidney failure and pulmonary embolism (artery blockage in the lung). The PHA also advises consumers to stop taking body building products from any manufacturer that claim to contain steroid-like substances or to enhance or diminish androgen-, estrogen-, or progestin-like effects in the body.
The FDA has received five adverse event reports, including serious liver injury, in men taking products marketed as dietary supplements by American Cellular Laboratories including TREN-Xtreme and MASS Xtreme. Acute liver injury is generally known to be a possible side effect of using products that contain anabolic steroids. Some of the cases resulted in hospitalization, but there were no reports of death or acute liver failure.
“Products marketed for body building and claiming to contain steroids or steroid-like substances are illegal and potentially quite dangerous,” said Commissioner of Food and Drugs Margaret A. Hamburg, M.D. “The FDA is taking enforcement action today to protect the public.”
The products listed in the Warning Letter to American Cellular Laboratories Inc., include “TREN-Xtreme,” “MASS Xtreme,” “ESTRO Xtreme,” “AH-89-Xtreme,” “HMG Xtreme,” “MMA-3 Xtreme,” “VNS-9 Xtreme,” and “TT-40-Xtreme,” and are sold on the Internet and in some stores. These products, which claim to contain steroid-like ingredients but in fact contain synthetic steroid substances, are unapproved new drugs because they are not generally recognized as safe and effective. In addition, the products are misbranded because the label is misleading and does not provide adequate directions for use.
Consumers taking body building supplements that claim to contain steroids or steroid-like substances should stop taking them immediately. Consumers should also consult a health care professional if they suspect they are experiencing problems associated with the products. Health care professionals and consumers are encouraged to report adverse events that may be related to the use of these types of products to the FDA's MedWatch Program by phone at 1-800-FDA-1088 or by fax at 1-800-FDA-0178 or by mail at MedWatch, HF-2, FDA, 5600 Fishers Lane, Rockville, MD 20852-9787.

Teva Pharmaceuticals USA issues a voluntary user-level nationwide recall of Propofol Injectable Emulsion 10 mg/mL 100 mL vials
Teva Pharmaceuticals USA is initiating a voluntary recall of Propofol Injectable Emulsion 10 mg/mL 100 mL vials, lot numbers 31305429B and 31305430B. The product lots identified are being recalled due to the presence of elevated endotoxin levels in some vials within these lot numbers.
Teva has been notified of 41 propofol-treated patients who experienced post-operative fever, chills and other flu-like symptoms. Based on available information it appears that all febrile or flu-like reactions were self-limiting with spontaneous resolution.
Adverse health effects, such as fever, chills, or rigors, are possible with exposure to product with elevated levels of endotoxins. Serious adverse effects, such as disseminated intravascular coagulopathy, acute respiratory distress syndrome, shock, and death, are possible with exposure to product with high endotoxin levels.
For use as an anesthetic agent, propofol should be used only by professionals trained in the administration of general anesthesia. For sedation of intubated, mechanically ventilated patients in the Intensive Care Unit, propofol should be administered only by persons skilled in the management of critically ill patients.
Customers who have Propofol lots 31305429B and 31305430B in their possession are instructed to cease using the product and return it to their distributor.
Teva Pharmaceuticals USA is voluntarily recalling the aforementioned lots. FDA and CDC have been apprised of this action.

FDA Announces Class I Recalls of Two Unapproved Devices
The U.S. Food and Drug Administration (FDA) announced a Class 1 recall today for two unapproved and uncleared devices whose manufacturers claimed could treat various medical conditions. A Class 1 recall means that there is a reasonable probability that the use of a device will cause adverse health consequences or death.
The manufacturers, VIBE Technologies of Greeley, Colo., and Nebion LLC of Los Angeles, Calif., claimed their devices treated conditions ranging from cancer to migraines. The FDA is concerned that based upon the original health claims made by the company, patients may forgo approved therapies, and that this could result in more severe illness or death.
"These recalls underscore the importance of taking action against manufacturers who make false medical claims for their devices," said Daniel G. Schultz, M.D., director of the FDA's Center for Devices and Radiological Health. "One of the FDA's primary responsibilities is protecting consumers from harm that can be caused by manufacturers who try to sidestep the approval and clearance process.”
Vibrational Integrated Bio-photonic Energizer device
On April 11, 2008, the FDA issued a warning letter to VIBE Technologies stating that the agency's November 2007 inspection of the facility showed that the company had not obtained FDA marketing approval or clearance for the Vibrational Integrated Bio-photonic Energizer (VIBE device), which claims to treat cancer, infections, and depression. The FDA also cited the company for substantial deviations from the current Good Manufacturing Practice/Quality System regulation.
VIBE Technologies initiated a recall of 840 VIBE devices in an April 3, 2008, letter sent to users. VIBE Technologies agreed to stop promoting and marketing the VIBE device, and will contact all those who had purchased it to ensure no other unsubstantiated medical claims are being made. The FDA has requested that the company update its recall notices to state that the VIBE device is not intended for the treatment of any diseases or medical conditions.
The FDA is aware of information that suggests that the VIBE device has been used in cancer patients. There is one death that occurred in a patient who used this device. However, FDA has not verified that there is any association between the death and the VIBE device.
HLX8 device
In June 2008 FDA inspected Nebion, LLC, which revealed that the company had not obtained FDA marketing approval or clearance for the HLX8 device, which claims to treat cancer, migraines, arthritis, and ruptured discs. The inspection also uncovered substantial deviations from the Current Good Manufacturing Practice/Quality System regulation.
Nebion recalled eight HLX8 devices on July 2, 2008, and notified their customers to stop using the devices immediately and to contact Nebion for their retrieval.
Nebion's first recall letter did not address the potential risks associated with the HLX8 device, but the company has recently notified FDA that they will issue a second letter that identifies potential health hazards. The FDA has not received any reports of injuries or deaths linked with the HLX8 device.
Under federal law, products that claim to diagnose a disease or condition, cure, mitigate, treat or prevent disease, or that are intended to affect the structure or function of the body are devices subject to FDA jurisdiction and may require FDA approval or clearance prior to marketing. Premarket approval is the most stringent type of FDA device review and is for devices with a high level of risk, such as those that support or sustain human life. FDA clearance is for lower risk devices that are shown to be as safe and effective as a similar device already on the market.
Neither VIBE Technologies nor Nebion has demonstrated to the FDA that their device is safe and effective at curing or treating diseases as claimed.
Health care professionals and consumers may report serious adverse events (side effects) or product quality problems with the use of this product to the FDA's MedWatch Adverse Event Reporting program either online, by regular mail, fax or phone.
* Online: www.fda.gov/MedWatch/report.htm
* Regular Mail: use postage-paid FDA form 3500 available at: www.fda.gov/MedWatch/getforms.htm and mail to MedWatch, 5600 Fishers Lane, Rockville, MD 20852-9787
* Fax: (800) FDA-0178
* Phone: (800) FDA-1088
Health care professionals and patients can obtain further details about the recalls from VIBE Technologies at 970-356-9594 or Nebion LLC, at 310-215-6400.

FDA Creates Web Page with Drug Safety Information for Patients, Health Care Professionals
Consumers and health care professionals can now go to a single page on the U.S. Food and Drug Administration's Web site to find a wide variety of safety information about prescription drugs. The Web page, http://www.fda.gov/cder/drugSafety.htm, provides links to information in these categories:
* Drug labeling, including patient labeling, professional labeling, and patient package inserts;
* Drugs that have a Risk Evaluation and Mitigation Strategy (REMS) to ensure that their benefits outweigh their risks;
* A searchable database of postmarket studies that are required from, or agreed to by, drug companies to provide the FDA with additional information about a drug's safety, efficacy, or optimal use;
* Clinicaltrials.gov, a searchable database of clinical trials, including information about each trial's purpose, who may participate, locations, and useful phone numbers;
* Drug-specific safety information, including safety sheets with the latest information about the drug as well as related FDA press announcements, fact sheets, and drug safety podcasts;
* Quarterly reports that list certain drugs that are being evaluated for potential safety issues, based on a review of information in the FDA's Adverse Event Reporting System (AERS);
* Warning Letters, Import Alerts, Recalls, Market Withdrawals, and Safety Alerts;
* Regulations and guidance documents;
* Consumer information about using medications safely and disposing of unused medicines;
* Instructions how to report problems to the FDA through its MedWatch program;
* Consumer articles on drug safety; and
* The FDA's response to the Institute of Medicine's 2006 report on the future of drug safety.
"By placing Web links to these up-to-date resources on a single page, we're helping consumers and health care professionals find drug safety information faster and easier," said Paul Seligman, M.D., M.P.H., associate director of Safety Policy and Communication in the FDA's Center for Drug Evaluation and Research. "This type of communication is aimed at helping consumers and health care professionals make well-informed decisions about medication use."
Establishing such a Web page is one of the requirements of the Food and Drug Administration Amendments Act of 2007, and is among FDA's many efforts to address the safe use of drugs throughout their lifecycle.

ETHEX Corporation Voluntarily Recalls Three Lots of Dextroamphetamine Sulfate 5mg Tablets Due to the Potential for Oversized Tablets
ETHEX Corporation announced today that it has voluntarily recalled three specific lots (77946, 81141 and 81142) of Dextroamphetamine Sulfate 5 mg tablets, as a precaution, due to the possible presence of oversized tablets. Oversized tablets may contain as much as about twice the labeled amount of the active ingredient. The recalled lots were distributed by ETHEX Corporation under an "ETHEX" label between January 2007 and May 2008. The 5 mg product is an orange round tablet debossed with "ETHEX" and "311" on one side.
If someone were to take a higher than expected dose of Dextroamphetamine Sulfate, then the risk of adverse effects known to be associated with the drug such as tachycardia, hypertension, tremors, decreased appetite, headache, insomnia, dizziness, blurred vision, stomach upset, and dry mouth may be increased.
No report of any oversized Dextroamphetamine Sulfate tablets has been received by ETHEX from any wholesaler, retailer, consumer or caregiver, and ETHEX has not received any report of unexpected side effects or injury related to this product.
ETHEX Corporation is conducting this precautionary, voluntary recall because it found a small number of oversized tablets in lots which had not yet been distributed. These oversized tablets were removed before the lots were distributed.
Please be aware that there are multiple companies in the United States producing and marketing generic versions of Dextroamphetamine Sulfate 5 mg tablets and consumers and their caregivers are encouraged to check their prescriptions to determine the source of their tablets.
Any customer inquiries related to this action should be addressed to ETHEX Customer Service at 1-800-321-1705, or fax to ETHEX Customer Service at 314-646-3751 or sent via email to: customer-service@ethex.com with representatives available Monday through Friday, 8 am to 5 pm CST.
ETHEX Corporation has initiated recall notifications to wholesalers and retailers nationwide who have received any inventory of the recalled lots of this product with instructions for returning the recalled product and, if they have not already done so, they are urged to contact ETHEX as provided above regarding procedures for returning the recalled product. Consumers and their caregivers should not use any Dextroamphetamine Sulfate tablets that appear to be oversized. If consumers have any questions about the recall, they should call the telephone number above, their physician, their pharmacist or other health care provider.
This recall is being conducted with the knowledge of the U.S. Food and Drug Administration (FDA).
Any adverse reactions experienced with the use of this product, and/or quality problems may also be reported to the FDA's MedWatch Program by phone at 1-800-FDA-1088, by Fax at 1-800-FDA-0178, by mail at MedWatch, FDA, 5600 Fishers Lane, Rockville, MD 20852-9787, or on the MedWatch website at www.fda.gov/medwatch.

Hopkins Experts: Most Vaccine-Allergic Children Can Still Be Safely Vaccinated
With close monitoring and a few standard precautions, nearly all children with known or suspected vaccine allergies can be safely immunized, according to a team of vaccine safety experts led by the Johns Hopkins Children’s Center. Writing in the September issue of Pediatrics, the multicenter research team offers pediatricians a step-by-step tool for quickly identifying children with allergic reactions to vaccines, and a much-needed guide, they say, to safely immunize those who are allergic.
Serious allergic reactions to vaccines are extremely rare — one or two per million vaccinations, according to some estimates — but when they happen, such episodes can be serious, even life-threatening, making it critical for pediatricians to instantly spot true allergic reactions and differentiate them from more benign nonallergic responses, investigators say. It is also crucial that pediatricians design a safe immunization plan for children with confirmed vaccine allergies. Children who have had one allergic reaction are believed to be at a higher risk for future reactions, typically more serious than the first.
“We cannot reiterate enough that the vaccines used today are extremely safe, but in a handful of children certain vaccine ingredients can trigger serious allergic reactions,” says Robert Wood, M.D., lead author on the paper and chief of pediatric Allergy and Immunology at Hopkins Children’s. “For the most part, even children with known allergies can be safely vaccinated.”
Given recent outbreaks of vaccine-preventable infections like measles, mumps and whooping cough in the United States, and measles and polio overseas, it is essential to safely vaccinate as many children as possible, investigators say.
Combing through available evidence on vaccine safety and allergies, the Hopkins-led team developed a sequence of instructions – an algorithm – that prompts physicians one step at a time on how to evaluate and immunize children with known or suspected vaccine allergies.
The guidelines are intended for doctors and parents who are uncertain about vaccine safety in children who have already had or are at high risk for having allergic reactions to vaccines.
In such cases, the Hopkins-led group advises a workup by an allergist, including skin prick testing—a prick on the skin or an injection under the skin with a small dose of vaccine or the suspected allergen from the vaccine—or blood tests that would detect the presence of characteristic antibodies that patients develop to allergens, such as antibodies to gelatin or egg proteins used in several common vaccines.
In many cases, allergic children can be vaccinated using alternative forms of a vaccine that are free of the allergen. Even if allergen-free formulations are unavailable, many children can still be vaccinated and remain under physician supervision for several hours after vaccination. Another option is testing the child to check for immunity. If blood tests show the child has already developed protective antibodies, it may be OK, at least temporarily, to withhold further doses of the vaccine, researchers write.
“Vaccines save lives, and parents should know that children who have had allergic reactions after a vaccine are likely to have developed protection against infection as a result of the vaccination,” says investigator Neal Halsey, M.D., an infectious disease specialist at Hopkins Children’s, and professor of International Health at the Johns Hopkins University Bloomberg School of Public Health.
“Most children who have had an allergic reaction after a vaccine can still be vaccinated against other diseases safely and some can receive additional doses of vaccines they might have reacted to,” Halsey adds.
Many children with known vaccine allergies who have low levels of protective antibodies and require more doses can be vaccinated safely under the guidelines. In some cases, children with known allergies can be given antiallergy medications, such as antihistamines and corticosteroids, before vaccination to help ward off or lessen the allergic reaction. For a step-by-step guide to vaccine administration in children with known or suspected vaccine allergy, see the full text of the article at http://pediatrics.aappublications.org/future/122.3.shtml.
Immunizations of children with known vaccine allergies should always be administered under medical supervision in a clinic equipped to treat life-threatening allergic reactions or in a hospital intensive-care unit. Patients can usually go home after an hour or two if they have no adverse reactions.
True allergies typically cause immediate reactions, involving the immune system as a whole that occur within a few minutes to a few hours of vaccination. By contrast, delayed reactions, which occur within days, even weeks after vaccination, are generally benign and are rarely, if ever, dangerous.
Symptoms of immediate allergic reactions include hives, swelling, wheezing, coughing, low blood pressure, vomiting, diarrhea, and can lead to full-blown anaphylaxis, a life-threatening allergic reaction.
The research was funded by the Centers for Disease Control and Prevention.
Co-investigators on the research: Melvin Berger, M.D. Ph.D., University Hospitals of Cleveland; Stephen Dreskin, M.D. Ph.D., University of Colorado; Rosanna Setse, M.D. M.P.H., Johns Hopkins University Bloomberg School of Public Health; Renata Engler, M.D., Walter Reed Army Medical Institute; Cornelia Dekker, M.D., Stanford University School of Medicine. The Clinical Immunization Safety Assessment Network, consisting of six medical research centers with expertise in immunization safety, was part of the study.
Conflict of interest disclosure for Hopkins investigators: Halsey has received research support from vaccine manufacturer Wyeth and is a consultant for vaccine manufacturers GlaxoSmithKline and Merck.

Arthritis Drugs and Cancer?
HHH Note: Sometimes, articles just catch our eyes. This one really made us sit back and think. What kind of future are we giving some of our youth?
All drug manufacturers are required to provide adverse reaction data to the FDA. Sometimes, the data can show some surprising and unexpected results after patient numbers increase dramatically. Does this mean some drugs have to be pulled from the market? What it really means is that we as consumers must investigate the drugs and question the physicians to be sure we are willing to take the risks for ourselves and our children.
