Aggressive Behavior and Mood Swings
Many consumers have experienced significant Chantix side effects, the brand name for the drug varenicline, while using it to aid in quitting smoking. Among many common side effects of Chantix, aggressive behavior and mood swings have been reported in a significant number of patients. While Chantix has been proven to increase chances of successfully quitting nicotine products, the frequency of negative side effects in patients prompted the FDA to include more severe warnings in 2009 about its side effects, including Chantix mood swings, Chantix related aggression, and depression while taking the drug. These symptoms may present in patients with no earlier psychiatric history and can aggravate the condition of those who have previously experienced mood imbalances.
Chantix aggressive behavior and mood swings prompt FDA alert
Varenicline was discovered by Pfizer and received a priority review by the FDA in February 2006. Due to the presumed safety and effectiveness of the drug, the typical trial period of 10 months was shortened to 6 months before the drug was released to the public. By February of 2008, the FDA issued an alert reporting a link between taking Chantix and experiencing Chantix related negative changes in mood and aggressive behavior. In May 2010, the Therapeutic Goods Administration of Australia received over 1000 reports of adverse side effects due to prescription varenicline, with 67% including psychiatric anomalies such as aggression, mood swings, and anxiety.
Chantix mood swings warning signs
It is recommended to consult a doctor if a patient experiences any of the following effects while taking Chantix:
- Feelings of anxiety
- Feelings of hopelessness
- Unusual mood swings
- Atypical thoughts or behaviors
- Feelings of anger or violent thoughts
- Tension or short-temper
These can be signs of dangerous mood-altering effects from taking Chantix. It is important to stop taking the medication immediately and seek medical help.
Chantix aggressive behavior risk factors
Common risk factors for experiencing Chantix aggressive behavior and Chantix mood swings include taking Chantix in higher doses; taking other medication or supplements that may interact with the drug; previous history of manic depression or bipolar disorder; increased nicotine intake while taking the drug; and stressful environment.
Many lawsuits have been filed against Pfizer, the company that manufactures Chantix, due to insufficient warnings in regards to their product. The most prominent Chantix lawsuit to this date was one filed by the parents of Carter Albrecht, who was shot to death in November of 2007 due to his erratic, aggressive behavior a week after being prescribed Chantix. Three more lawsuits were issued out of New York in January 2010, and all federal lawsuits have been consolidated into a multidistrict litigation (MDL) reporting to the U.S. District Court for the Northern District of Alabama.
