Tepezza Hearing Loss Lawsuit Overview

The Tepezza Lawsuit claims that Horizon Therapeutics failed to properly warn patients and doctors about the risk of permanent hearing loss and other auditory side effects associated with the drug.

Plaintiffs allege that despite growing evidence linking Tepezza to serious hearing damage, the manufacturer continued to market it as a safe and effective treatment for Thyroid Eye Disease (TED) without adequate warnings.

On this page, we’ll discuss the Tepezza Lawsuit for hearing impairment and permanent hearing loss,

Tepezza Lawsuit: Thyroid Eye Disease (TED) Treatment Linked to Severe Hearing Impairment

Tepezza, a prescription drug for Thyroid Eye Disease (TED), has been linked to severe and potentially permanent hearing loss in some patients.

Tepezza Hearing Loss Claims against Horizon Therapeutics allege that the company failed to adequately warn users about these risks, despite growing evidence of hearing-related side effects.

Many individuals who took Tepezza report experiencing tinnitus, muffled hearing, and even total hearing loss after treatment.

As a result, the Tepezza litigation is underway, with cases consolidated in a multidistrict litigation (MDL) in the Northern District of Illinois.

Plaintiffs argue that Horizon neglected its duty to disclose the full extent of Tepezza’s risks, leaving patients vulnerable to life-altering complications.

Those affected may be eligible to seek compensation for medical expenses, lost wages, and the impact of their hearing loss on daily life.

Legal action is being strategized by our attorneys for Horizon Therapeutics’ failure to properly warn patients of potential hearing loss side effects.

Lawsuit Updates

February 3, 2025

In February 2025, the number of Tepezza Lawsuits increased to 203, reflecting a rise of 3 filings compared to the 200 cases in January 2025.

Plaintiffs allege that Tepezza has caused serious and permanent hearing loss, a side effect that was not sufficiently warned about by the manufacturer.

The relatively small rise in filings demonstrates that more individuals affected by the drug’s adverse effects are seeking legal recourse.

Tepezza Lawsuit Overview

Tepezza is a drug used to treat Thyroid Eye Disease (TED), produced by drug manufacturer Horizon Therapeutics.

Tepezza’s “mechanism of action” is to block IGF-1R, a protein found on the surface of human cells and a key driver of Thyroid Eye Disease (TED).

By doing so, symptoms of TED are reduced, such as swelling, inflammation, double vision, blurred vision and other vision problems.

Tepezza Linked to Hearing Related Side Effects

Despite its intended benefits as a thyroid eye disease treatment, reports soon emerged that Tepezza was linked to serious hearing loss in some patients.

Research suggests that blocking IGF-1R may also interfere with auditory functions, leading to conditions such as tinnitus, muffled hearing, and, in some cases, permanent hearing impairment.

Plaintiffs in the Tepezza Hearing Loss Lawsuit allege that Horizon Therapeutics failed to adequately warn patients about these risks, leaving many to suffer unexpected and life-altering side effects.

Some individuals have developed permanent hearing loss after completing Tepezza treatments, impacting their ability to work, communicate, and engage in daily activities.

Those who experienced serious hearing loss after taking Tepezza may be eligible to seek compensation for medical costs, lost wages, and diminished quality of life.

If you’ve taken Tepezza and subsequently suffered hearing loss, you may be eligible to file a Tepezza Lawsuit and seek financial compensation.

Is There a Tepezza Class Action Lawsuit?

No, there is currently no Tepezza class action lawsuit. Instead, individual Tepezza cases have been grouped into a multidistrict litigation (MDL) in the Northern District of Illinois.

The MDL legal process is used to consolidate Tepezza lawsuits that share similar claims—such as allegations that Horizon Therapeutics failed to warn about the risk of Tepezza-related hearing loss—while still allowing each plaintiff to pursue their own case.

Unlike a class action, where all plaintiffs are treated as a single group and receive equal compensation, multidistrict litigation (MDL) allows for individualized outcomes based on the specific details of each case.

This means that while pretrial proceedings, discovery, and expert testimony are handled collectively, each lawsuit can result in different settlements or verdicts depending on the severity of the plaintiff’s hearing loss and other damages.

Plaintiffs in the Tepezza MDL claim that Horizon Therapeutics knew or should have known about the risk of permanent hearing impairment but failed to properly warn patients and doctors.

If the MDL results in favorable rulings for plaintiffs, individual settlements or jury verdicts will be determined on a case-by-case basis.

Those affected by Tepezza-related hearing loss can still file claims and have their cases considered as part of the ongoing litigation.

Studies Show Potentially Permanent Hearing Damage in Tepezza Users

Research studies have found that a shocking percentage of patients who received Tepezza infusions suffered from hearing loss, tinnitus and other hearing problems.

Initial studies found that hearing related side effects only impacted around 10% of those who received Tepezza infusions.

In more recent studies, such as one published by the Endocrine Society, up to 65% of patients experienced hearing loss or hearing problems.

Studies Show Potentially Permanent Hearing Damage in Tepezza Users

The hearing problems suffered by Tepezza patients are serious:

“Of the 17 patients with new hearing symptoms, four had new or worsening sensorineural hearing loss, a type of hearing loss resulting from damaged hair cells in the inner ear. Three patients had patulous eustachian tube, a disorder in which the channel that runs between the middle ear and back of the nose and throat stays open. Normally, these eustachian tubes remain closed and open only occasionally to regulate air pressure around the ear drum. After three months, symptoms of patulous eustachian tube improved, but did not completely disappear. Two patients with sensorineural hearing loss had improvement in symptoms at one and six months.”

Filing a Tepezza Lawsuit

If you or a loved one took Tepezza to treat Thyroid Eye Disease and subsequently suffered from hearing related side effects, you may be eligible to file a claim.

If you do qualify for a Tepezza Lawsuit, there are some steps our legal team recommends taking.

Filing a Tepezza Lawsuit

These steps include gathering evidence and assessing damages, both of which an experienced dangerous drug attorney can help you with.

Your Tepezza Lawyer will also guide you through the civil lawsuit process entirely.

Gathering Evidence for a Tepezza Lawsuit

Evidence is extremely important in dangerous drug lawsuits.

Lawsuits are won and lost based on the quality of evidence available, so it’s important that you retain all relevant documentation pertaining to your potential Tepezza lawsuit.

Gathering Evidence for a Tepezza Lawsuit

Evidence in Tepezza Lawsuits may include:

  • Medical records
  • Personal testimony on hearing loss or tinnitus
  • Proof of costs related to injuries or hearing problems
  • Medical bills and receipts, such as purchase records for hearing aids
  • Tepezza prescription information

Assessing Damages for a Tepezza Lawsuit

Damages refer to the total economic and non-economic losses incurred as a result of an injury.

Assessing Damages for a Tepezza Lawsuit

In Tepezza hearing loss lawsuits, damages may include the following:

  • Medical costs and bills
  • Pain and suffering, mental health effects
  • Lost wages or income
  • Loss of enjoyment of life
  • Permanent disability
  • Other damages

Projected Tepezza Lawsuit Settlement Amounts

Hearing Loss Lawsuits involving the medication Tepezza may be resolved through settlement negotiations with the drug manufacturer.

Tepezza Lawyers estimate that the average Tepezza settlement may range between $75,000 and over $200,000 depending on factors present in an individual’s case.

Factors that may influence a Tepezza settlement can include: 

  • Strength of the claim
  • Available evidence
  • Extent of injuries
  • Damages incurred
  • Medical expenses
  • Other individual factors

These Tepezza payout projections are by no means a guarantee of compensation in the Tepezza Lawsuit, they are merely estimations based on settlements in mass tort lawsuits involving dangerous medications.
