Black Box Warning

Wellbutrin XL (bupropion hydrochloride) and Suicidal Thoughts – Black Box Information

Wellbutrin XL and Zyban contain bupropion. Like many other antidepressants, these medications have “black box” warning regarding the increased risk of suicidal thoughts.

The black box warning on antidepressants is required by FDA to provide important safety information. However, some of these warnings are exaggerated, causing panic and decrease access to mental health care. When it was implemented in 2005, the magnified danger message resulted in a slew of media reports about the link between antidepressants and suicide.

The black box warning on the FDA website states, “Advise patients and caregivers that the patient using bupropion for smoking cessation should stop taking bupropion and contact a healthcare provider immediately if agitation, hostility, depressed mood, or changes in thinking or behavior that are not typical for the patient are observed, or if the patient develops suicidal ideation or suicidal behavior.”

Bupropion hydrochloride is an antidepressant used for smoking cessation (Zyban) and to treat a variety of conditions, including depression and other mental disorders or mood disorders (Wellbutrin XL). Antidepressants can help prevent suicidal thoughts or attempts and provide other benefits. However, a small number of people (especially people under the age of 25) who take antidepressants for any condition may experience new or worsening depression, other mood symptoms, or suicidal thoughts. It is very important to talk with the doctor about the risks and benefits of antidepressant medication, even if treatment is not for a mental or mood condition.

There is no question that antidepressant medications can cause harm if used inappropriately.  What the FDA may not recognize is that a black box warning can stop many adolescents and young adults from seeking care. According to Statnews.com, this has led to a decrease in seeking help for these conditions. Without seeking help, appropriate medication therapy can be provided. Without drug therapy for these individuals, suicide attempts may actually increase.

Antidepressant medications do have a place in modern medicine. These drugs help many people fight depression. Medications like Wellbutrin (bupropion) are effective for many individuals if it is prescribed safely. Patients should get a proper counselling regarding the use of these medications, including risks and benefits. This discussion with your health care provider needs to take place at the time of prescribing.

For further information about antidepressants and black box warnings please consult with your physician or health care provider.  These important conversations should provide a more realistic view of the risks versus the benefits of antidepressant medications.
