Chantix® & Diabetes

Schmidt & Clark, LLP is No Longer Taking These Cases - If you feel that you may have a potential case, we urge you to contact another law firm adequately suited to handle your case.

The use of Chantix® has been associated with a number of adverse events consistent with new-onset diabetes. Lawsuits are currently being considered.

What’s the problem?

Diabetes, clinically known as diabetes mellitus, is an incurable condition in which the pancreas is unable to produce enough or any insulin, a hormone that regulates blood sugar and energy levels. Without enough insulin, blood sugar levels drop, and diabetics will start to experience:

  • anxiety
  • clamminess
  • confusion
  • heart palpitations
  • seizures
  • sweatiness
  • tremors
  • unconsciousness

An examination of adverse event reports received by the FDA between May 2006 and December 2007 revealed at least 544 reports suggesting Chantix side effects may have caused a loss of glycemic control, including a number of cases that contained symptoms and lab tests consistent with onset of diabetes. This likely represents only a small portion of the true number of adverse events experienced by users, as it is generally accepted that only about 1% to 10% of all serious events are reported to the FDA.

While many of the reported adverse events in this category were a result of weight gain or weight loss, which could be expected among a population of people quitting smoking, a large number of the cases had classic indications of new onset diabetes mellitus from Chantix. This included reports of elevated blood glucose, hunger, thirst and frequent urination.

The best way to prevent the serious side effects associated with taking Chantix is to regularly visit your doctor and to be aware of the symptoms of Chantix-related health problems. Since the symptoms of diabetes are clearly general, any Chantix user experiencing these health changes should visit their doctor for blood tests and a proper diabetes diagnosis.
