A study conducted in 2021 found that as many as 2 out of 3 patients who undergo Tepezza treatments for thyroid eye disease are at risk for hearing loss and other hearing-related symptoms.
The study collected data on 26 patients who received at least four injections or infusions of Tepezza. Of those patients, 65% reported new problems with their hearing, including:
Loud hearing of a person’s own voice (29%)
Ringing in the ears (tinnitus) (27%)
Hearing loss (23%)
Plugged ear sensation (12%)
Most patients probably would not have taken Tepezza if they knew they had a considerable risk of developing permanent hearing loss or another serious hearing-related injury.
