Misleading Seroquel Weight Gain Statements Earn Ethics Violation in UK

  • Written by: Staff Writers

British regulators say that some of AstraZeneca’s claims about the potential weight gain side effects of Seroquel constituted a breach of ethics under that country’s pharmaceutical codes of conduct. 

On Monday, the Prescription Medicines Code of Practice Authority concluded that AstraZenca acted in a deceptive manner in at least one Seroquel ad published in the U.K. more than five years ago, which claimed that the drug did not cause as much weight gain as other antipsychotics. The authority says that the statement did not match the known evidence about the risk of weight gain and other Seroquel problems that AstraZeneca had on hand at the time the ad was published.

The UK panel highlighted an advertisement in the British Journal of Psychiatry in 2004, which claimed in large print that Seroquel had a favorable weight profile. The panel concluded that the advertisement was misleading, because the studies AstraZeneca used to support the claim were faulty, which the drug maker should have known. The ad was determined to have violated the requirement that all claims be accurate, fair and able to be substantiated.

The ethics violation ruling comes as the company faces about 26,000 Seroquel lawsuits in the United States, all of which claim that AstraZeneca failed to adequately warn users about the risks of weight gain from Seroquel, which can lead to diabetes and other serious injuries.

The first Seroquel trial is currently underway in New Jersey state court.

What AstraZeneca knew about the weight gain effects of Seroquel is expected to take center stage in this case, as well as other lawsuits pending in state and federal courts throughout the U.S. Internal documents produced during the Seroquel litigation suggest that the drug maker was aware of the potential weight-gain Seroquel side effects and continued to promote the drug as weight-neutral for years after clinical evidence demonstrated significant problems that could lead to diabetes and other injuries.

The drug maker has racked up $656 million in legal defense costs fighting the failure-to-warn lawsuits over Seroquel. In addition, Seroquel lawyers continue to file new cases for individuals who have developed diabetes, pancreatitis and a rare movement disorder known as tardive dyskinesia, so the cost of the litigation is expected to continue to increase.

    I took the medication gain about 40 lbs , I sleep all day I had muscle spams and muscle cramps. I think the weight gain also lead to me having high blood pressure no problems with bp before taking the med. the medication had a lot of side effects. I slower took my self off the med and I m working on losing this weight. but i still have some side effects.

    I had chronic depression in the past year and missed 3 months of work.None of the medications I was taking were helping. I had some long term wellness while I was seroquel and was put back on this medication. Although my mood has improved the weight gain is very upsetting. I have had night time eating cravings. I have gained 30 lbs on this medication and my weight does not budge despite dietary corrections. I have contemplated getting off this medication but, it provides me mental stability. I am going to make an appt this week to see my family doctor. My psychiatrist has been told about this side effect but, has not offered me an alternative.
