Tepezza Lawsuit for Hearing Loss & Tinnitus

The adverse effects of harmful drugs can be devastating. Some medications can cause serious health problems like heart attacks, strokes, and seizures.

Some patients do not experience any problems when taking a particular drug. However, other patients may have severe side effects leading to hospitalization or death.


Drug manufacturers must list the possible adverse effects of a drug in the product's labeling, but only some are listed on the label. Patients may not know the risks associated with a particular drug until they experience a problem.

Have you suffered hearing loss or other severe symptoms after taking Tepezza? The personal injury attorneys at Rosenfeld Injury Lawyers, LLC can take immediate legal action to hold the pharmaceutical company financially accountable for your damages.

What Is Tepezza?

The Food and Drug Administration (FDA) approved Tepezza on January 21, 2021, to treat a dull-related active thyroid eye disease (TED), a debilitating, rare autoimmune disease called Graves' eye disease.

Common TED symptoms include eye bulging, eye pain, vision loss, difficulty closing eyes, and light sensitivity.

The Administration approved the drug after years of clinical trials evaluating the generic form (teprotumumab) and publishing the results in the New England Journal of Medicine. During the clinical trials, participants received IV (intravenous) infusions between one time every three weeks. The trial needed for FDA approval lasted for six months.

Currently, each vial of the drug costs approximately $15,000, generating more than $800 million in a single year for the pharmaceutical company. After two clinical trials, many patients developed severe side effects, especially those previously diagnosed with pre-diabetes and diabetes before beginning their prescription.

What Is Thyroid Eye Disease?

Thyroid eye disease (TED) is a condition that affects the thyroid gland and the eyes. The most common symptoms of TED include:

  • Bulging eyes
  • Redness in the white of the eye
  • Pressure or pain behind the eye
  • Difficulty reading signs
  • One eye moving slower than the other
  • Swollen eyes
  • Eyelid swelling
  • A gritty, dry eye sensation
  • Watery eyes
  • Light sensitivity
  • Blurry or double vision
  • Color vision loss
  • Vision loss

While there is no cure for TED, there are treatments that can help reduce the symptoms. One such treatment is Tepezza, which reduces eye bulging and double vision.

While Tepezza can effectively treat TED, it can also cause some side effects, including headaches, dizziness, and nausea. In some cases, Tepezza can also cause blurred vision and dry eyes.

While these side effects can be bothersome, they are usually temporary and go away after a few weeks. Talk to your doctor if you are experiencing any of these side effects.

How Does Tepezza Help?

Tepezza and the generic teprotumumab-trbw treat thyroid eye disease (TED) or Graves' eye disease. TED causes swelling in the tissues surrounding the eyes, causing pain, blurry vision, and sometimes even loss of sight. Tepezza helps reduce swelling and improve vision.

Graves disease is an autoimmunity disorder where the body's immune system mistakenly identifies healthy cells in the eye as foreign invaders. When it does this, it causes inflammation and swelling in the area around the eyes. Over time, this damage can lead to scarring and permanent vision loss.

The most common symptom of thyroid eye disease is swollen eyelids, often accompanied by eye irritation, burning, itching, or a feeling of pressure behind the eyes.

While many people experience no symptoms at all after taking the drug used to treat Thyroid Eye Disease, others develop symptoms that may include:

  • Double and blurry vision
  • Drooping eyelids
  • Excessive tearing
  • Light sensitivity
  • Difficulty focusing

What Pharmaceutical Company Manufactures Tepezza?

Horizon Pharmaceuticals manufactures Tepezza (teprotumumab-trbw). Horizon Therapeutics distributes the drug that works at the source of the disease by helping the body produce enough thyroid hormone, alleviating many Thyroid Eye Disease symptoms by producing an atomic change in affected tissue.

The pharmaceutical company states that the medication decreases proptosis, improves diplopia, and improves functional vision within 24 weeks of taking the drug.

Taking Tepezza to Treat Thyroid Eye Disease: Permanent Hearing Loss and Other Side Effects

By March 2021, numerous studies identified concerns with Tepezza used to treat thyroid eye disease. The Endocrine Society revealed that 20 of the 26 patients in their study were diagnosed with an auditory impairment that had not been previously identified as a safety issue.

In the Horizon Therapeutics data, only 10% of the Tepezza users involved in their study developed hearing loss problems compared to the 77% of the patients involved in the Endocrine Society study who had experienced Tepezza hearing loss.

One report indicated that Horizon pharmaceuticals took action to ignore relevant safety concerns about it Tepezza infusions and likely intentionally conspired to hide the lack of efficacy in taking the medication.

Tepezza Hearing Loss Injuries

Many men and women who have already been diagnosed with vision problems have developed severe side effects after taking the drug, including permanent loss of hearing.

Medical science determined that there are serious hearing-related side effects from taking the Food and Drug Administration (FDA)-approved Grave's disease drug, including:

  • Permanent hearing damage, including mild hearing loss or tinnitus (constant ringing in the ears)
  • Bilateral hearing loss
  • Severe hearing impairment
  • Sensorineural hearing loss due to damage to the inner ear
  • Long-term hearing problems
  • Permanent hearing loss
  • Hyperacusis (a hearing disorder involving loudness perception)
  • Hearing distortion (variable hearing loss)
  • Autophony hearing problems involving enhanced perception or echoing sounds caused by the patient's own voice
  • Eustachian tube dysfunction

The First Product Liability Lawsuit Involving Tepezza

Tepezza lawsuit lawyers filed a civil action against the drug maker, claiming that Horizon pharmaceuticals Inc failed to take action and alert regulators of the serious concerns of Tepezza hearing loss and other auditory problems, excluding hearing-related side effects.

The Tepezza hearing loss lawsuit involved an Arizona man who suffered permanent hearing loss and tinnitus (ear ringing). The plaintiff's doctor prescribed the medication administered through Tepezza infusions every three weeks between June 2020 and September 2020.

The plaintiff alleges that the pharmaceutical company failed to notify him or his doctors of the known serious health risks associated with taking Tepezza, including hearing loss and ringing in the ears.

The medication's negative hearing side effects will likely lead to many more Tepezza lawsuits in the months and years ahead, involving plaintiffs seeking financial compensation for damages.

Client Reviews
Jonathan Rosenfeld was professionally objective, timely, and knowledgeable. Also, his advice was extremely effective regarding my case. In addition, Jonathan was understanding and patient pertaining to any of my questions or concerns. I was very happy with the end result and I highly recommend Jonathan Rosenfeld. Michonne Proulx
Extremely impressed with this law firm. They took control of a bad motorcycle crash that left my uncle seriously injured. Without any guarantee of a financial recovery, they went out and hired accident investigators and engineers to help prove how the accident happened. I am grateful that they worked on a contingency fee basis as there was no way we could have paid for these services on our own. Ethan Armstrong
This lawyer really helped me get compensation for my motorcycle accident case. I know there is no way that I could have gotten anywhere near the amount that Mr. Rosenfeld was able to get to settle my case. Thank you. Daniel Kaim
Jonathan helped my family heal and get compensation after our child was suffered a life threatening injury at daycare. He was sympathetic and in constant contact with us letting us know all he knew every step of the way. We were so blessed to find Jonathan! Giulia
Jonathan did a great job helping my family navigate through a lengthy lawsuit involving my grandmother's death in a nursing home. Through every step of the case, Jonathan kept my family informed of the progression of the case. Although our case eventually settled at a mediation, I really was impressed at how well prepared Jonathan was to take the case to trial. Lisa
