Investigating Tepezza’s Impact on Auditory Function

Tepezza, a drug primarily used to treat thyroid eye disease (TED), has recently come under scrutiny for its potential impact on auditory function. While initially hailed as a breakthrough medication, concerns have emerged regarding its association with hearing loss and tinnitus. 

As patients and healthcare professionals navigate these uncertainties, investigations are underway to comprehensively understand Tepezza’s effects on auditory health. 

In this article, we will discuss Tepezza’s potential impact on auditory function. We will also discuss the associated mechanisms, lawsuits, evidence, regulatory responses, and future research.

Understanding Tepezza’s Mechanism of Action

Tepezza, developed by Horizon Therapeutics, functions by targeting insulin-like growth factor-1 receptors. According to Medical News Today, these receptors play a crucial role in the pathogenesis of thyroid eye disease (TED). 

By binding to these receptors, Tepezza inhibits inflammation and tissue expansion within the orbit, thereby reducing the ocular symptoms associated with TED. While its primary indication lies in treating TED, researchers are exploring the possibility of off-target effects on auditory pathways. 

Understanding these mechanisms is vital for comprehensively assessing the drug’s potential impact on auditory function and informing clinical decision-making. It also guides the clinical decision-making process.

Examining Tepezza Hearing Loss Lawsuits

The emergence of the Tepezza hearing loss lawsuit reflects growing concerns regarding its potential adverse effects on auditory health. Plaintiffs allege that the manufacturer failed to adequately warn about the risk of permanent hearing impairment or tinnitus associated with Tepezza use. 

Drugwatch notes that as of May 2024, 113 cases are pending in the Tepezza litigation. According to TorHoerman Law, these legal proceedings highlight the experiences of the victims of the severe side effects of Tepezza. Such cases underscore the importance of thorough risk assessment and transparent communication regarding medication-related side effects.

Clinical Evidence and Patient Reports

Clinical evidence and patient reports provide valuable insights into the auditory effects of Tepezza. Initial clinical trials reported a relatively low incidence of hearing issues. However, subsequent studies have indicated a higher risk, with up to 65% of patients experiencing hearing problems. 

According to AboutLawsuits, these findings were supported by a study of 26 Tepezza users, where 23% experienced hearing loss and 27% reported tinnitus. Patient testimonials further corroborate these findings, emphasizing the need for comprehensive monitoring of auditory function during Tepezza treatment.

Regulatory Responses and Label Changes

In response to mounting concerns, regulatory bodies have taken action to address Tepezza’s auditory risks. The FDA mandated label revisions in July 2023, requiring enhanced warnings regarding hearing impairment, including potential permanence. 

This regulatory intervention followed Horizon Therapeutics’ addition of a warning to Tepezza’s label. This warning advised healthcare providers to assess patients’ hearing before, during, and after treatment. These measures aim to improve patient safety and ensure informed decision-making regarding Tepezza therapy.

Future Directions and Research Initiatives

Moving forward, ongoing research initiatives aim to deepen our understanding of Tepezza’s impact on auditory function. Longitudinal studies, pharmacovigilance programs, and post-marketing surveillance efforts will play a crucial role. They will help assess the prevalence, severity, and reversibility of auditory complications associated with Tepezza.

These initiatives strive to mitigate risks and optimize treatment outcomes for individuals receiving Tepezza for TED by fostering collaboration among stakeholders. This includes clinicians, researchers, and regulatory authorities. These efforts are essential for ensuring the safety and efficacy of Tepezza therapy in the management of thyroid eye disease.


What is the mechanism of action of Tepezza?

Tepezza’s mechanism of action involves targeting the insulin-like growth factor 1 receptor (IGF-1R), which reduces inflammation and tissue expansion in the orbit. This action helps alleviate symptoms associated with thyroid eye disease (TED), the drug’s primary indication.

Is Tepezza-induced hearing loss permanent?

Tepezza-induced hearing loss can be permanent in some cases. While symptoms may resolve for some patients after discontinuing treatment, others may experience persistent hearing impairment even after stopping Tepezza therapy. 

Is Tepezza approved for chronic TED?

Tepezza (teprotumumab) is approved for the treatment of thyroid eye disease (TED), including the chronic form of the condition. It is the only FDA-approved medication specifically indicated for TED, addressing both active inflammation and associated symptoms. This approval represents a significant advancement in the management of TED.

In conclusion, the investigation into Tepezza’s auditory effects emphasizes the importance of thorough risk assessment and transparent communication. Legal actions, label revisions, and ongoing research efforts signify a proactive response to safety concerns.

Collaboration among stakeholders is crucial in optimizing patient care. The evolving landscape of Tepezza’s risks requires continued vigilance. Efforts to understand, mitigate, and communicate these risks are essential for patient safety and informed decision-making.
