How the Tepezza Lawsuit Impacted Thyroid Eye Disease Patients

Tepezza Lawsuit

In recent years, a glimmer of hope emerged for those grappling with the discomfort and aesthetic challenges posed by Thyroid Eye Disease (TED). Tepezza, an innovative pharmaceutical treatment, held the promise of alleviating symptoms and improving the quality of life for TED patients. 

However, the journey towards the widespread adoption of the drug was not without its share of controversies, legal battles, and unforeseen consequences.

According to the National Institutes of Health (NIH), TED is a chronic immune-mediated inflammation of the orbit. This condition, characterized by swelling and inflammation around the eyes, represents a significant challenge for those affected. 

It is a condition often associated with Graves' disease (GD), a common autoimmune disorder affecting the thyroid gland. Remarkably, approximately 25 to 50% of individuals diagnosed with GD find themselves confronted with the additional burden of thyroid eye disease.

This article delves into the impact of the Tepezza lawsuit on the lives of individuals battling TED.

Tepezza and the Risk of Hearing Loss

Tepezza, the first FDA-approved drug for TED, is a significant medical advancement introduced in January 2020. This autoimmune disorder can lead to permanent vision impairment, making Tepezza's approval a ray of hope for many. However, recent developments have raised concerns regarding its safety profile. 

According to Ophthalmology Times, the US Food and Drug Administration (FDA) updated the drug's warning label to include a crucial addition. The risk of hearing impairment or loss.

This updated label now carries a warning that explicitly mentions “hearing impairment including hearing loss” as the drug's potential side effects. It stands alongside other warnings and precautions, such as exacerbation of preexisting inflammatory bowel disease, infusion reactions, and hyperglycemia. 

The FDA's new advisory suggests that Tepezza may lead to severe hearing impairment, which, in some instances, could be permanent. As a result, medical professionals are advised to assess patients' hearing both before and after treatment with Tepezza. They are also required to carefully consider the potential benefits and risks associated with the medication. 

The Tepezza Lawsuits

The Tepezza lawsuit has become a focal point of contention, with a series of allegations challenging Horizon Therapeutics, the drug's manufacturer. These lawsuits primarily revolve around allegations related to the risk of hearing loss associated with Tepezza. 

Horizon Therapeutics had initially alerted the FDA about Tepezza's low risk of causing hearing loss or tinnitus before its approval. It estimated that only a small percentage, approximately 10%, of users would be affected and that any side effects would be temporary.

However, the heart of the issue lies in the assertion made by plaintiffs in these lawsuits. They contend that Horizon Therapeutics significantly downplayed the risk of hearing damage connected to Tepezza, arguing that the company grossly understated the potential harm. This discrepancy in risk assessment has resulted in at least 34 Tepezza lawsuits being consolidated into a Multi-District Litigation (MDL).

TruLaw notes that the potential outcomes of these lawsuits are still uncertain. However, they could result in significant repercussions for both the pharmaceutical industry and TED patients. 

The Impact of the Tepezza Lawsuits on TED Patients

As reported by, a recent product liability lawsuit against the manufacturer of Tepezza has sparked concerns regarding the drug's impact on patients. This lawsuit, filed by Syed Zafar, alleges that crucial information regarding the risk of permanent hearing damage associated with the drug was withheld.

Patients like Zafar, who had been seeking relief from TED through Tepezza infusions, have faced not only physical consequences but also emotional turmoil. The lawsuits have eroded confidence in the drug's safety and effectiveness, causing anxiety and uncertainty among TED patients. 

Moreover, the financial implications cannot be ignored, as the increasing scrutiny and legal actions have the potential to affect treatment costs and insurance coverage. The Tepezza lawsuits have left TED patients grappling with their medical condition and the unexpected challenges posed by the legal battles surrounding their treatment.

The Future of Tepezza

The likelihood of Tepezza remaining on the market depends on the legal proceedings' outcomes and Horizon Therapeutics' ability to effectively address the allegations. While alternative treatments for TED, such as surgery and corticosteroids, have existed, Tepezza represented a promising non-surgical option.

If Tepezza's availability is compromised, it may lead to a resurgence of interest in these alternative treatments. Moreover, the Tepezza lawsuits have broader implications for the pharmaceutical industry. It potentially affects drug pricing, marketing practices, and patient access to innovative therapies. The industry will closely watch how this legal battle unfolds, as it could set precedents for future cases.


The Tepezza lawsuit has cast a shadow of uncertainty over the future of this once-promising treatment for TED. The fate of the drug now hinges on the pharmaceutical company's ability to navigate these legal challenges effectively and address the allegations against it.

Beyond the immediate effects on TED patients, the lawsuits hold broader implications for the pharmaceutical industry. They spotlight concerns related to drug pricing, marketing practices, and patient access to innovative treatments. 

As this legal battle evolves, it reminds us of the intricate interplay between healthcare, legal aspects, and the pursuit of cutting-edge medical solutions. It significantly influences the trajectory of patient care and the landscape of pharmaceutical development.
