Tepezza® Linked to
Permanent Hearing Loss & Ototoxicity
If you were treated with Tepezza (teprotumumab) for Thyroid Eye Disease and developed permanent hearing loss, tinnitus, ear fullness, or other hearing problems, you may be entitled to significant compensation.
What is Tepezza?
Tepezza (teprotumumab-trbw) is an intravenous biologic medication approved to treat Thyroid Eye Disease (TED). Manufactured by Horizon Therapeutics (now part of Amgen), it was the first drug specifically approved for TED.
While effective for eye symptoms, many patients have reported permanent hearing damage after treatment.

Tepezza can cause ototoxicity leading to irreversible hearing loss, tinnitus, ear fullness, and autophony.
Hearing-Related Injuries
Permanent sensorineural hearing loss, tinnitus, muffled hearing, ear pressure, autophony, and in some cases complete deafness in one or both ears.
Evidence
- High rate of hearing problems reported in clinical trials
- Many cases are permanent even after stopping treatment
- FDA has received numerous adverse event reports
