Tepezza (teprotumumab) is an infusion drug approved by the FDA in 2020 to treat thyroid eye disease (TED). Marketed as a breakthrough therapy, it quickly became the standard of care.
However, clinical studies and patient reports revealed that Tepezza can cause serious auditory side effects, including permanent hearing loss and tinnitus. Horizon did not add warnings about these risks until July 2023, years after evidence first emerged.
Data from Horizon’s own Study 401 suggested that up to 40% of patients experienced hearing-related adverse events. Despite this, patients were not properly warned, and no audiological monitoring was recommended until 2023.
Common side effects reported include:

As of August 2025, more than 250 Tepezza lawsuits are consolidated into a federal multidistrict litigation (MDL) in the Northern District of Illinois. The first bellwether trial is scheduled for August 3, 2026, with additional trials set through early 2027.
Recent filings include cases like that of an Indiana woman who alleges she suffered permanent hearing loss after Tepezza infusions from 2021–2022. At the time, the drug label contained no hearing loss warnings, which were only added in July 2023.

What is thyroid eye disease (TED), and why is Tepezza prescribed for it?
Thyroid eye disease is an autoimmune condition that causes inflammation and bulging of the eyes. Tepezza was the first FDA-approved drug for TED, but patients later reported hearing-related side effects.
When were hearing loss warnings added to Tepezza’s label?
The FDA-approved label for Tepezza did not include hearing loss risks until July 2023, despite earlier data suggesting up to 40% of patients experienced auditory problems.
What are the symptoms of Tepezza-related hearing problems?
Patients have reported ringing in the ears (tinnitus), muffled hearing, difficulty understanding conversations, balance problems, and in some cases, permanent hearing loss.
Is Tepezza part of a class action lawsuit?
No. At this time, Tepezza lawsuits are being handled as individual claims consolidated into a federal multidistrict litigation (MDL) rather than a class action.
How long do I have to file a Tepezza lawsuit?
Each state has its own statute of limitations for product liability claims, generally between 2–3 years from the time of injury or discovery of the injury. Consulting a lawyer quickly is important to protect your rights.
If you suffered hearing loss or tinnitus after Tepezza infusions, don’t wait. Legal deadlines apply, and early action strengthens your case.
