Chantix Heart Attack and Stroke Risk Highlighted

Less than one month after the FDA warned about the risk of Chantix heart problems, a new study published in a Canadian medical journal finds that side effects of Pfizer’s stop-smoking drug may increase the risk of a heart attack, stroke or other cardiovascular event by 72%, even among smokers who have no prior history of heart disease.

>>MORE INFORMATION: Chantix Heart Attack and Stroke Lawsuits

The Chantix lawyers at Saiontz & Kirk, P.A. are reviewing potential lawsuits on behalf of users of this prescription medication throughout the United States. For several years, our lawyers have been representing individuals and families who are pursuing Chantix suicide lawsuits over the psychiatric side effects of the medication, which were not adequately disclosed to many users. Evidence is now mounting in support of lawsuits for heart attacks and strokes from Chantix as well.

According to a report published this week by the Canadian Medical Association Journal, smokers who took Chantix face a 72% increased risk of suffering a serious cardiovascular event, including a heart attack or stroke, when compared to smokers who were given a placebo.

These findings come only three weeks after the FDA warned that individuals with pre-existing cardiovascular disease may face an increased risk of heart problems and required Pfizer to update the warnings about the potential Chantix heart side effects. However, this study suggests that even individuals without pre-existing heart disease may face an substantial increased risk of problems.

The study looked at 700 smokers who participated in a number of clinical trials and found much higher rates of heart attacks and other cardiovascular events among smokers who took Chantix, as compared to those who took a placebo. One in 28 Chantix users had serious cardiovascular events, even though they had no history of cardiovascular disease or any other heart problems.

Although consumers turn to Chantix to help them quit smoking and improve their health, it appears that the drug may actually increase the risk of heart attacks, strokes and other heart problems people are trying to avoid by quitting.

We have been writing on this blog for some time that the side effects of Chantix outweigh the minimal benefits provided in helping people stop smoking. Two of the researchers involved in this new study found the findings troubling enough to agree that the FDA should now seriously consider issuing a Chantix recall.

Chantix is already the drug linked to the most reported adverse events of any drug on the market. Last month, France pulled the plug on the drug due to the risk of violence and suicide from Chantix, revoking government reimbursements for citizens who decided to risk taking it.


As a result of Pfizer’s failure to adequately study their drug and warn about the findings of this pre-existing clinical data earlier, individuals who have suffered serious heart problems after Chantix use may be entitled to financial compensation through a Chantix lawsuit for a stroke, heart attack or other cardiovascular event.

The attorneys at Saiontz & Kirk, P.A. provide free consultations and claim evaluations for individuals who suspect that they or a family member may have a claim. All Chantix stroke and heart attack lawsuits are pursued under a contingency fee, which means that there are no attorney fees unless we are successful obtaining compensation for your injury.

    My son had two strokes last year at the age of 40. The first was mild and he lost some communication skills. The second was very sever and the right side of his body was paralysed. He had no medical history of high blood preasure or high colesterol. He was taking Chantix at the time. He was evaluated by neuroligist and they could not determine why he had the strokes. He was evaluated by Dr Rishi Gupta at Grady Hospital in Atlanta GA. Dr Gupta performed angiaplasty and installed a stint to unblock a major artery.

    John Jr. has been in rehab for almost a year now and has made some progress. But the Drs have decided that he has reached a plateau and is not making progress. His rehab has been stopped.

    I have taken chantix 3 times as perscribed as a stop smoking program provided by my company Lockheed Martin (health and wellness program)
    I experienced dangerously high blood pressure in May of 2012, went to my family Dr. He took me off the medicine and doubled my blood pressure medine to get it back down. It has high and is now currently spiking at 188 over 122. I have been to the ER twice in the last 2 days and they are attempting to get my uncontrolled blood pressure under control . Before May 2012, my blood pressure medicine was working fine. Even with the increase of dosage, it is not working.

    I started taking Chantix to help stop smoking. I suffered very awful night terrors to the point my sleep was very disrupted so I talked to my doctor and I stopped taking the medicine. A few months later I suffered a TIA that the doctors still to this day can’t explain. I recovered almost completely, but still have some painful issues I deal with daily. Could Chantix be the cause of my stroke?

    I had a stroke 6 weeks after stopping Chantix. I was in the hospital for three weeks. When I came I could not move my right side and could not speak. That was a year and a half ago. I am unable to work and have been forced to go on disability.

    John took Chantix for at least 8 months and stopped smoking. On June 27th,2015. On August 30th he suffered a major heart attack and had to be air lifted to Jackson Hospital. The cardiologist administered 3 stents and he he has major damage to his heart. They have said that it may repair some but not very much and on a long period of time. The perscriptions that he has do not say any warnings on the meds saying anything about heart attacks or strokes. Only that pregnant or nursing women should not take. Hiss last two prescriptions were issued on August 10, 2015 and on Sept 2nd, 2015. Which he just recently stopped taking when he found out that it could cause heart problems. Neither his personal care physician nor his cardiologists have ever broached this subject or ever told him to stop taking. Up until just last week he was still on it.

    I was on chantix for a month and a half. While on the meds I went completely numb on the left side of my body and my face started drawing on the left. Lucky my wife was able to get me to the ER in time and they started a medication call TPA I stayed in ICU for 2 days and a regular room. I have regained 99% of my normal function just I am unable to speak like I once was. My have never had and heart problems or high blood pressure. When I got to the ER my blood pressure was 166/115 and now I am stuck taking blood pressure meds for the rest of my life as well as blood thinner due to chantix restricting the blood flow to my head

    Chantix causes blood clots when not taken with some blood thinner the FDA is aware of this and has a study on chantix causing PE blood clots, Pfizer hides these facts in its advertising to patients and physicians and should be criminally prosecuted. Rather than say chantix causes blood clots they criminally mislead by saying “ causes new or worse blood vessel problems” every time the FDA try’s to take action against Pfizer suitcases full of money flow from Pfizer to the FDA headquarters. Both the FDIT and FAS have banned the use of chantix for truck drives, pilots, and air traffic controllers. I had a blood clot cause a stroke about a week after quitting chantix and being taken off my blood thinners
