Zyban Suicidal Thoughts & Heart Side Effects

The U.S. Food and Drug Administration (FDA) believes the smoking cessation drug buproprion hydrochloride—sold under the brand name Zyban, but also as an antidepressant named Wellbutrin, Voxra, Budeprion, and Aplenzin (formerly Amfebutamone)—might cause suicidal ideations and behaviors, and problems with preexisting heart complications.

What Is Zyban and What Is It Prescribed For?

Zyban is the brand name for the drug buproprion hydrochloride. Made and sold by British pharmaceutical company GlaxoSmithKline, this prescription medication is used to treat nicotine addiction. The same chemical compound can also be used as an antidepressant.

Zyban prevents the brain’s absorbtion of two neurotransmitters, dopamine and norepinephrine. Unlike Selective Serotonin Reuptake Inhibitors (SSRIs), Zyban does not inhibit the reuptake of serotonin. The specific mechanism of action by which Zyban prevents people from smoking is unknown.

Burroughs Wellcome, a British pharmaceuticals company that has since merged with others into GlaxoSmithKline, first developed buproprion back in 1969. The FDA approved the drug as Zyban in 1997, and doctors prescribe it in 150 mg oral release tablets.

Zyban can cause multiple side effects: drowsiness, excitement, dry mouth, dizziness, headache, nausea, vomiting, tremors, weight loss, constipation, and excessive sweating.

As the adverse effects of Zyban become better known, the FDA has required more stringent product warnings and prescription requirements, culminating with a July 2009 “black box” Zyban warning. There is no effort to remove the product, and no Zyban recall is in effect.

Zyban Might Cause Suicidal Ideations and Behaviors

The FDA has known that buproprion causes suicidal ideations and behavior when it’s prescribed as an antidepressant for some time. In 2006, the FDA analyzed the results of 372 studies of antidepressants, finding that even young adults (ages 18-25) were also afflicted with behavioral changes. As a result, the FDA ordered antidepressant manufacturers, including GlaxoSmithKline for Wellbutrin, to include added warnings to consumers.

In July 2009, the FDA issued a public health advisory notifying physicians and patients that it required GlaxoSmithKline to place black box warning on Zyban products. Thanks to a review of postmarket surveillance and the adverse event reports it received, the FDA determined that Zyban might cause the following neuropsychiatric side effects:

  • Hostility
  • Agitation
  • Aggression
  • Anxiety
  • Depressed mood
  • Mania
  • Psychosis
  • Panic
  • Hallucinations
  • Paranoia
  • Delusion
  •  Suicidal thoughts and behavior
  • Attempted suicide

These symptoms appeared in Zyban users regardless of prior diagnosis of psychiatric ailments, but GlaxoSmithKline did not test Zyban on people with serious psychiatric illness such as schizophrenia or bipolar disorder before it sought FDA approval. The FDA added that many people who quit smoking show symptoms of depression without drug intervention.

Other Zyban Side Effects

Recently, a study conducted at Duke University concluded that those with coronary artery disease faced greater risk of death due to buproprion use. The researchers could not determine the reasons for the connection, but they found the connection statistically significant. For those with heart disease, in an average three years of follow-up, 21.4 percent of the participants still on antidepressants died as opposed to 12.5 percent who were not on antidepressants.

    I have recently come to learn how harmful Zyban can be. I do not know if there is any relevance here, because of the timeframe, however, I firmly believe I was greatly harmed by the use, under the direct supervision of the physician assistant at my former place of employment, of Zyban during a smoking cessation program. This occurred, however, during the late 90's. I actually completed the program, with use of the drug, but shortly thereafter, I became severely depressed, to the point where I actually could not leave my home to go to my place of employment, and I had a really terrific job! I was a single mother with 2 young children I had been taking good care of up until that time. I was employed by a major utility, with great pay and benefits, and had been there for nearly 20 years. I lost my job, had my car repossessed, lost my home, was suicidal, and it was only through the grace of God, and the faith of a dear friend now deceased and my sister/best friend that I am alive. There is more to the story, but I don't want to go into it more unless there is good reason to. It was a terrible, painful time in my life, a time which scarred, not only me for life in some ways, but my children as well.

    I don't know if GlaxoSmithKline was aware of the potential harm of their drug at the time, but I do not recall any warnings that I could become suicidal.
