Tezepaz (teprotumumab) was the talk of the town when it became the first FDA-approved medication for thyroid eye disease (TED) due to its astounding results in reducing inflammation and protruding eyes. Now, in recent years this attention has shifted to Tepezza lawsuits owing to audio injuries including tinnitus or permanent loss of hearing that multiple patients claim is a result of using the drug.
This article aims to summarize the steps parties interested in this ongoing case will need to consider after the class action litigation gained traction in 2025.
Understanding the Mechanism Behind Tepezza Hearing Loss
Tepezza treats TED by blocking the insulin-like growth factor 1 receptor (IGF-1R) signaling pathway. Additionally, IGF-1R plays a key role in the preservation of the cochlea, which holds essential functions in the inner ear. Losing cochlear structures is likely to cause a disruption of path which leads to loss of auditory structures and therefore quite a few cases of Tepezza hearing damage.
Studies conducted on adults have shown that nearly 65% of them reported some forms of audio damage, such as tinnitus, had greatly diminished ability to hear, or complete deafness. These results were never showcased during the clinical trial phases or the early stages of approval by the FDA.
Evidence Linking Tepezza to Severe Hearing Loss Cases
Clinical evidence and patient histories are increasingly correlating the use of Tepezza with hearing loss complications. Numerous peer-reviewed studies have found relationships between Tepezza usage and hearing loss, leading the FDA to demand changes to the warning label concerning the risks of hearing loss under the affairs of Tepezza regulatory affairs.
This emerging evidence without a doubt incentivizes the rise in product liability lawsuits against Horizon Therapeutics, ranging from individual lawsuits to class actions. Currently, over one thousand consolidated cases of Tepezza hearing loss lawsuits are classified under MDL (multidistrict litigation) for Tepezza, with several bellwether trials set to commence shortly.
The Legal Battle: Tepezza Hearing Loss Lawsuits Explained
The Tepezza lawsuits focus on the litigation of Tepezza concerning the alleged failure of Horizon Therapeutics to appropriately warn patients and doctors regarding the possibility of permanent hearing loss. Some of the major claims consist of:
- Esssentially For Months
- Claim about general failure with no restraints
- Lack of marketing regulations
These claims are driving the Tepezza multi district litigation with pretrial procedures for greater productivity retained by federal systems. The outcome of forthcoming Tepezza bellwether trials is likely to determine near future settlement sums of Tepezza and anticipated jury payouts to Tepezza jury.
Now that the litigation for Tepezza is underway, claims are starting alongside parallel major mass torts such as the PFOA MDL lawsuit, updates on the PFAS lawsuit, updates on the 3M PFAS lawsuit, Inhance Technologies lawsuit, and PFAS thyroid lawsuit. There is a clear case where the public is starting to call out for information and protection regarding health issues of negligence done by big corporations.

Claimants with personal injury claims for Tepezza may seek compensation for:

Preliminary estimations of legal counsel on settlement considerations point towards strong financial settlements regarding hearing impairment resulting from the use of Tepezza. Undoubtedly, these settlements will be enhanced with the prospect of accrued interest damages. The first settlements by the jury hearing the main cases will set the standard for settlement amounts for the MDL.
Like the settlement of ARCHER 3M et al. and the explanation of the 3M EIF Fund, it is also believed that Horizon will establish some form of a relief fund to facilitate quicker resolution for greater numbers of plaintiffs in the Tepezza class action lawsuits.
