FDA: Anti-depressants must carry
'black box' warning
(November 2004 Issue)

By Jennifer Elise Chase

The Food and Drug Administration has mandated that all antidepressant medications must carry a "black box" warning, alerting to doctors, patients and parents their risk of suicidal thoughts and behavior or "suicidality," in the children and adolescents who take them. The warning will also emphasize to doctors the need to closely monitor patients started on these medications.

The October 15 mandate followed a September hearing in Washington, D.C. where a 23-person panel of federal health advisors told the FDA that nine medications should carry a "black box" warning, or an information sheet from the drug companies to accompany the medications, stating that they can cause suicidal thoughts and self-injurious behavior in patients 18 and younger.

Panel members told the FDA that Prozac and the other "new generation" antidepressants are causing suicidality in two to three percent of children under age 18, or 20,000-30,000 per the one to two million adolescent patients who take them.

The medications recommended for the label are: Prozac, Zoloft, Wellbutrin, Celexa, Effexor, Remeron, Paxil, Serzone, and Luvox. Prozac is currently the only FDA-approved adolescent antidepressant, but doctors regularly prescribe other drugs of the same type, called "selective serotonin reuptake inhibitors" or SSRIs.

FDA has also said that a Patient Medication Guide (MedGuide) is being made which will be given to patients receiving the drugs advising them and their parents of the risks and precautions that can be taken to ensure their safety.

"For the most part [the FDA] will usually insist on our interpretation of the data, being the data that is put into the label" says Sandra Kweder, M.D., acting director of the FDA's Office of New Drugs, Center for Drug Evaluation. "Sometimes the specific words are what ends up being negotiated but it is the FDA's interpretation of the data that will go into the label."

Kweder expects FDA will send text of the labels to manufacturing companies within the next several weeks. The FDA is hopeful that consumers will have access to the guides within the next four to six weeks.

The FDA has included all antidepressants in the new warning for adolescents - both new and some "older generation" antidepressants. According to Russell Katz, M.D., director of the FDA's Neuropharmacological Drug Products Center for Drug Evaluation and Research, research supports that several antidepressants in other classes caused patients to exhibit the same suicidality.

"The signals seem to be pretty much consistent across the drug classes that were studied," says Katz. "For that reason we considered that this effect most likely related to antidepressants widely defined."

The "black box," which according to the FDA is the most serious labeling that can appear on any medication, does not prohibit the use of antidepressants in children and adolescents.

"Adolescents do respond very well to these medications," says Carol M. Wester, RN, MSN, APRN, of Hopewell Associates in Mattapoisett, Mass. "The National Institutes of Mental Health has reported that suicide rates among children and adolescents have fallen over the past several years; [but], does that mean that these medications are actually responsible for that encouraging trend? It is difficult to know how to interpret the trends and data."

Hopewell Associates specializes in treating adolescents with Autism Spectrum Disorders and many of its patients suffer from symptoms of depression. Wester says that a black box warning cannot substitute for good clinical judgment and practices. But a warning in clear view is ultimately a good idea.

"It may scare some people away from treatment; it may increase the liability of the prescriber; it may dampen direct advertising in the popular media to patients and their parents; it may drive down the cost of drugs a bit via the increased prescribing of generic [Prozac] … but the problem is that at the end of the day, we still have a population of depressed children and adolescents who are suffering," she says.
