Antidepressant Suicide Warning For Young Adults

Los Angeles, California – – The FDA announced on May 2 that it has asked antidepressant manufacturers to expand the current black box warnings concerning the increased risk of suicidality in children and adolescents to include young adults, but only ages 18 to 24.

Baum Hedlund’s statement regarding the FDA’s newest suicide warning:

We are getting closer to warnings that match what the internal, unpublished data owned by the drug companies (and not entirely seen by FDA) show regarding the risk for antidepressant-induced suicidality and violence. Unfortunately, this new warning, rather than simply and accurately informing the public that this side effect can occur in some people – no matter their age, instead gives a false perception that some age groups are entirely safe while others are not.

It is unrealistic and unwise to think that a person is at risk the day before their 25th birthday, but then safe and no longer at risk of becoming suicidal while taking these drugs one day later. This obviously problematic interpretation was a significant concern raised by some FDA advisory committee members who met on December 13, 2006, to discuss the FDA’s analysis of suicidality in adults taking antidepressants. Parsing out the data in an effort to draw lines around particular age groups appears to be designed to salvage certain markets for the drugs, nothing more.

As I stated during my public testimony before the FDA on December 13, 2006, does a drug know how old a person is? When their 25th birthday is? When a company seeks approval for a drug, does the FDA parse out the efficacy data by age group? Of course not. We know that breast cancer happens most often in women over 50. But, does that mean that women cannot get cancer in their 30s? No. So, why are we parsing out age groups for side effects that can happen in all age groups, whether or not it happens more often in one age group than another?

Suicidal Behavior is Higher in Patients Treated with Paroxetine (Paxil) Compared with Placebo

It is extremely misleading for the FDA to state that “scientific data” does not show an increased risk in adults older than 24. In fact, according to one antidepressant manufacturer’s analysis of suicidality in adults, for “adults with MDD [Major Depressive Disorder] (all ages), the frequency of suicidal behavior was higher in patients treated with paroxetine compared with placebo. [ ] This difference was statistically significant.”

How does the FDA reconcile this with the statement that the “scientific data” does not show a risk above the age of 24? With FDA’s proposed labeling, patients and their doctors will be mollified into thinking that if they are 25 years old or older, they have nothing to worry about. As a result, more lives will be lost.

Instead of drawing age group lines, patients and healthcare providers need to be informed that this side effect can occur in some people – no matter the age – and the listed symptoms are dangerous precursors to suicidal and violent behavior. Properly educated medical professionals, patients, family members, and caregivers can distinguish the unusual behavior and take steps to prevent them from escalating to self-harm or harm to others.

Clinical Trial Evidence Shows Risk Since the 1980s

Although the expanded warning is an improvement, it certainly is not, as the FDA’s Steven Galson states, a representation of “FDA’s commitment to a high level of post-marketing evaluation of drug products.” In fact, the clinical trials that formed the basis of the FDA’s analysis have been in existence for years. The truth is that the clinical trial evidence from 15 and 20 years ago, even before the drugs were approved, showed signals of risk. The FDA’s own medical staff raised concerns about the side effect profile of these drugs in the 1980s and 1990s, but their admonitions were ignored by their superiors.

Finally, FDA’s action today continues to ignore all evidence outside of the clinical trial data created by and provided to it by antidepressant manufacturers. The FDA is ignoring independent analyses conducted by scientists in the field, as well as historical and foreign regulatory actions dating back over 20 years.

5-Fold Greater Risk of Suicide in SSRI-treated Elderly Patients

In fact, the FDA’s statement that antidepressants have a “protective effect” for those over the age of 65 is inconsistent with a recent study of elderly patients, which found a nearly 5-fold greater risk of suicide in SSRI-treated patients compared to patients receiving other antidepressants in the first month of treatment. [Juurlink, DN, Mamdani, MM, Kopp, A, Redelmeier, DA. The Risk of Suicide With Selective Serotonin Reuptake Inhibitors in the Elderly, The American Journal of Psychiatry (May 2006).]

We believe, without question, drug companies and their apologists are putting a great deal of pressure on the FDA. Despite all of the controversy and exposed failures surrounding the FDA in the past few years, it appears that the FDA simply cannot muster the guts to act without industry influence. Absent this influence, there would be no reason why the FDA wouldn’t insist on warnings for all ages. No doubt, drug companies are a formidable force, but the FDA must remember whose interests it is supposed to protect. If it does not, the representatives of the people, Congress, will have to step in.
