Lawsuit Alleges Gardasil Injection Caused Postural Orthostatic Tachycardia Syndrome (POTS) and Other Injuries

The lawsuit claims Merck downplayed the risks of Gardasil injections and overplayed the threat of cervical and anal cancer from HPV.

According to allegations raised in a recently filed product liability lawsuit, side effects of Gardasil injections caused a Florida woman to develop neurological and heterogenous autoimmune injuries, including a condition known as postural orthostatic tachycardia syndrome (POTS), which has left her with permanent pain and health problems.

The complaint (PDF) was filed by Ashley Muller in the U.S. District Court for the Northern District of Florida in October, presenting claims against Merck & Co. as the defendant.

Gardasil was first approved in 2006, and has been widely marketed for young girls and boys before adolescence and potential sexual activity, to help prevent HPV, which can be sexually transmitted and lead to the development of cervical cancer.

According to the Gardasil lawsuit, Muller received three injections, beginning at age 19, with one in August 2015, another in October 2015, and a third in March 2016. However, within a month of receiving the first injection, Muller began to experience symptoms of fatigue, headaches, joint pain, dizziness and brain fog, the lawsuit indicates.

Over time, and following the other Gardasil injections, her condition worsened, causing severe joint pain which worked its way to her jaw and led to a temporomandibular joint disorder (TMJ) diagnosis. Her symptoms led her to quit her job in October 2015.

Later, she developed severe stomach pains, nausea, anxiety, depression and panic attacks, and began to suffer hair loss. In May 2016, her gall bladder failed and it had to be removed.

“Based upon her chronic and severe post-Gardasil symptoms and adverse events as outlined above, and the tests performed by her medical providers, Plaintiff has been diagnosed with various medical conditions, including but not limited to, postural orthostatic tachycardia syndrome (POTS), dysautonomia, alopecia areata, biliary dyskinesia, irritable bowel syndrome (“IBS”), small intestinal bacterial overgrowth (SIBO), bile acid malabsorption (BAM), and temporomandibular joint disorder (TMJ),” the lawsuit states. “(T)he medical literature has documented other patients who, like Plaintiff, have suffered serious autonomic dysfunctions, and who experienced the same side effects as those Plaintiff has suffered, and who were diagnosed with Gardasil-induced autonomic diseases.”

The lawsuit claims Merck engaged in false advertising both to deceive the public about the efficacy of the Gardasil injections, and to overemphasize the risks of HPV.

“Merck aggressively and fraudulently concealed the risks of the vaccine in broadcast materials and in propaganda that it disseminated in the United States,” Muller’s lawsuit alleges. “Merck sold and falsely promoted Gardasil knowing that, if consumers were fully informed about Gardasil’s risks and dubious benefits, almost no one would have chosen to vaccinate.”

Muller’s lawsuit presents claims of negligence, failure to warn, manufacturing defect, breach of warranty and common law fraud.

Gardasil Side Effects

Since its introduction, concerns about Gardasil injection problems emerged after one of the lead researchers responsible for developing the HPV vaccine, Dr. Diane Harper, indicated that the drug’s protection may only last a few years, suggesting that the risks may outweigh the benefits.

Dr. Harper reportedly said at a conference in 2009, that while Gardasil was tested on 15 year old girls, it is commonly being given to girls as young as nine years old. She has called for more detailed warnings to parents about the Gardasil risks and to provide additional information about the unknown long-term benefits for girls who are not likely to be sexually active for several years.

Many health experts strongly support the use of Gardasil, indicating any risks are negligible and claims made by those concerned about vaccinations are often not scientifically supported.

The National Cancer Institute has heralded the HPV vaccine, saying that widespread use could reduce cervical cancer deaths worldwide by as much as two-thirds. Many also suggest men get the vaccine as well in order to promote “herd immunity,” which occurs when a large enough portion of the population is vaccinated against a particular disease that they act as a firewall, preventing that disease’s spread even to those who are not vaccinated.

    I have developed several conditions since participating in the Gardisil trials. I now live with POTS, among other disabling conditions. I was misdiagnosed and mistreated for years. I'm curious as to how they are still able to administer? I've seen lawsuits years ago, but missed the deadline. I'm hoping someone can help.
