Tepezza (teprotumumab-trbw) is a prescription medicine used to treat Thyroid Eye Disease (TED). TED often occurs in people living with Graves’ disease (too much thyroid hormone). TED and Graves’ disease are both autoimmune disorders, but are different conditions and are treated differently. With an autoimmune disorder, your immune system mistakenly attacks your own healthy tissues.
Other names for thyroid eye disease (TED) include:
- Graves’ orbitopathy
- Graves’ ophthalmopathy
- Graves’ eye disease
- Graves’ disease eyes
- Thyroid-associated ophthalmopathy
TED
Thyroid Eye Disease (TED) is a rare, serious and sight-threatening autoimmune disease. It is a progressive disease and can get worse over time. You can develop TED without having Graves’ disease. With TED, the muscle and fat behind the eye is attacked and becomes inflamed and red, leading to symptoms. Specialists recommend getting a diagnosis and treatment as early as possible.
The symptoms of TED may include:
- eye bulging
- double vision
- dry, gritty eyes
- watery eyes
- blurry vision
- light sensitivity
- eye pain or pressure
- misaligned eyes
- itchy eyes
- swollen, puffy, red eyes or eyelids
- eyelids are pulled back
- color vision loss
- blindness (rare)
Graves' disease
Graves’ disease is caused by overproduction of thyroid hormones (hyperthyroidism). In Graves’ disease the thyroid is attacked and leads to an overproduction of thyroid hormones. The thyroid gland sits at the base of your neck. Up to 50% of people diagnosed with Graves’ disease will develop TED.
Graves’ disease is often treated with antithyroid medicines like methimazole (Tapazole) or propylthiouracil, beta-blockers, radioactive iodine therapy or surgery. Endocrinologists are the specialists that usually manage Graves’ disease.
The symptoms of Graves’ disease include:
- eye bulging
- anxiety
- irritability
- tremor in the hand or fingers
- increased sweating
- weight loss (despite normal eating)
- enlarged thyroid gland (goiter)
- changes in a menstrual cycles
- erectile dysfunction
- decreased sex drive
- frequent bowel movements
- tiredness
- trouble sleeping
- thickened red skin, often on the feet or front of legs
- irregular heartbeats. Not everyone who has Graves’ disease gets TED.
