Perhaps you’ve seen this ad about a drug for thyroid eye disease. If so, you may be wondering what thyroid eye disease is — and why the woman in the ad is wearing five pairs of sunglasses at once. Read on for answers.

What is thyroid disease and how does it affect the eyes?

The thyroid gland is a small, butterfly-shaped organ at the front of the neck. It releases thyroid hormone, which helps control many functions in the body. If it releases too much thyroid hormone (hyperthyroidism) or too little (hypothyroidism), bothersome and sometimes serious symptoms may develop, including changes in muscle strength, bowel function, and heart function.

An overactive thyroid gland can cause thyroid eye disease, prompting swelling and inflammation in tissues surrounding the eyes. The condition causes bulging eyes, a dry, gritty sensation in the eyes, tearing, pressure or pain behind the eyes, and blurring or double vision.

As many as half a million people in the US have thyroid eye disease. It affects up to half of people with Graves’ disease, an autoimmune illness marked by an overactive thyroid.

Thyroid eye disease ad: The pitch and the evidence

The ad opens with a woman wearing large, dark sunglasses, identified as a real patient named Jeanne. “With thyroid eye disease,” she explains, “I was always wearing sunglasses to hide my bulging eyes. I wore them just about everywhere.”

She removes her sunglasses to reveal that she’s wearing another pair underneath. In fact, she’s wearing three pairs of sunglasses and later will be wearing five!

As the music turns upbeat, she continues: “But then my doctor recommended Tepezza, a prescription medicine for thyroid eye disease, and I didn’t have to hide so much.”

A drawing of a bulging eye morphing into a more normal eye accompanies her next words: “In a clinical study, more than eight out of 10 patients taking Tepezza had less eye bulging. And nearly seven out of 10 saw improvements in double vision.”

Warnings about this medicine

You know what comes next: a fast-talking voiceover warning of possible side effects. For Tepezza, these include:

• Infusion reactions. Now we learn that Tepezza is an intravenous (infused) medicine. A course of treatment is eight 90-minute infusions, each separated by three weeks. Infusion reactions may be mild or severe, including allergic reactions (such as itching or hives) and other side effects that occur during or just after the infusion (such as fever or sweats).
• When to call for advice. “Tell your doctor right away if you have symptoms such as high blood pressure, fast heartbeat, shortness of breath, or muscle pain,” the voiceover instructs. Keep in mind that most people with high blood pressure have no symptoms, but if severe it can cause headaches, blurry vision, or chest pain.
• Before starting treatment. If you have diabetes or inflammatory bowel disease, or if you are pregnant or planning to become pregnant, you should tell your doctor before starting treatment. That’s because Tepezza may harm a developing fetus or worsen other diseases.

A big finish: Controlling thyroid eye disease

As the commercial winds down, Jeanne is back, removing her fifth consecutive pair of sunglasses to reveal normal-appearing eyes. “I look more like my old self again. Now I wear sunglasses because I want to.”

“Ask your doctor if Tepezza is right for you,” the narrator advises before suggesting a visit to the website for before and after pictures of Jeanne. I checked; they’re impressive.

What the ad gets right

The ad accurately describes

• thyroid eye disease symptoms
• how the condition alters appearance and can cause embarrassment
• results of a single, small study investigating the risks and benefits of Tepezza.

What else do you need to know about treatments for thyroid eye disease?

• You must treat thyroid disease as well as your eye condition. Medicines or surgery are often good options. Radiation therapy may be effective, but sometimes makes thyroid eye disease worsen.
• Selenium, a mineral supplement, is recommended by some experts.
• Quitting smoking is always recommended, partly because smoking may worsen thyroid eye disease.

If thyroid eye disease is mild, moisturizing eye drops, eye shades or patches, or dark sunglasses may be sufficient.

If thyroid eye disease is moderate to severe, options include:

• medicines that suppress inflammation or an overactive immune response. Examples include glucocorticoids, teprotumumab (Tepezza), mycophenolate mofetil (Cellcept), tocilizumab (Actemra), or rituximab (Rituxan).
• surgery to remove excess tissue around the eyes.

Small studies, like the one cited in the ad, may not detect all side effects, especially rare ones.

Last, but certainly not least: Tepezza is expensive. The price for a year of treatment can be $300,000 or more — and insurance coverage varies.

The bottom line

I still don’t know why the woman in the ad wears multiple pairs of sunglasses at the same time. Maybe it’s to emphasize how serious she is about hiding her eyes. Or maybe it’s just a way to grab our attention. Direct-to-consumer drug marketing strategies can be even more mysterious than the illnesses they hope to treat.

If you’re concerned you may have thyroid disease or thyroid eye disease, talk to your doctor. A costly new drug may be an option for some people, but it pays to learn about all options. Academic medical centers, the NIH, or a medical society are more likely to give you reliable and balanced information than a drug ad.

Here’s a new fact about spring, summer, fall, and sometimes even winter, now that climate change has blurred seasonal boundaries: sizzling heat may be on the way, or currently blanketing your community.

High temperatures stress the body, leading to thousands of heat-related illnesses and deaths every year in the US. Creating a personal heat plan can help you stay safe when the heat index soars.

Caleb Dresser, MD, MPH, is the health care solutions lead for C-CHANGE, the Center for Climate Health and the Global Environment at the Harvard T.H. Chan School of Public Health, and an emergency medicine doctor at Harvard-affiliated Beth Israel Deaconess Medical Center. Below we interview him about who, how, and why heat harms. Then we’ll help you create your personal heat safety plan.

Interview edited for clarity

Who is especially vulnerable during hot weather?

High temperatures can affect anyone. But some people — children, outdoor workers, people who are pregnant or have health problems or disabilities, and older people — are more likely to experience harm when temperatures rise. For example:

• Young children, especially babies, have less physical capacity to deal with very high temperatures.
• People working outdoors may not have access to shade and could be performing physically intensive labor. They need adequate hydration, adequate breaks, and access to a cool space during break time, as OSHA guidelines spell out.
• People with chronic medical conditions, such as kidney disease or heart disease, may have difficulty adapting physiologically to hot weather, or may be more susceptible to its health impacts.
• And some people living with disabilities or certain neurological conditions may have difficulty with thermoregulation — that is, controlling the temperature of their bodies — or may not be able to take actions that keep them safe, such as taking off layers or moving to a cool area.

Which weather patterns create dangerous levels of heat?

Dangerous heat is the result of both high temperatures and high humidity, which interfere with our ability to cool off by sweating. In dry areas, extremely hot temperatures can be dangerous on their own.

Danger zones vary across the United States and around the world. But hospital use and deaths rise once we get above threshold temperatures. The threshold varies in different places depending on whether bodies, cultures, and architecture are adapted to heat.

For example, here in New England, where some people (particularly those of limited means) may not have access to air conditioning, we see increases in healthcare use and deaths at a lower temperature than in the American South, where people and organizations may be more used to dealing with hot weather.

When does hot weather become dangerous to our health?

Risk goes up the longer hot weather sticks around.

One hot day can put some people at risk. A stretch of several hot days in a row during a heat wave is particularly dangerous because it can overwhelm people’s ability to adapt. Eventually people run out of physiological reserves, leading to greater health harms and greater need for medical care.

Surprisingly, spring and early summer are particularly dangerous times because people and organizations aren’t as prepared for hot weather.

How to create your personal heat safety plan

Five key points to help you create a personal heat plan are below. Americares offers further information through heat tip sheets developed with the Harvard C-CHANGE team that are tailored to people in different health circumstances.

Planning is important because intense heat is occurring more often: a Climate Central analysis found 21 additional risky heat days, on average, for 232 out of 249 locations between 1970 and 2022.

• Stay ahead of hot weather. Check apps, websites, TV, or radio for updates on weather today and in coming days. If local weather alerts are available by phone or text, sign up.
• Have a cooling plan. When temperatures soar, you need to spend as much time as possible in cool spaces. Plan options if your home is likely to be too hot and unsafe to stay in. You may be able to stay with a neighbor or family member who has air conditioning until a heat wave passes. Many cities and towns have neighborhood splash pads for children, and open cooling centers or air-conditioned libraries, public buildings, or community centers to everyone — sometimes even overnight. Spending time in air-conditioned businesses or malls, or in a shady green space like a park, may help too.
• Sip plenty of fluids. Water is the best choice. Skip sugary drinks and avoid caffeine or alcohol.
• Use fans correctly. Fans help if surrounding air is relatively cool. If air temperatures are very high, it’s important to dampen your clothes or skin to help keep your body from overheating, and move to a cooler location, if possible.
• Know your personal risks and the signs of heat-related illness. If you have health problems or disabilities, or take certain medicines such as diuretics, talk to your doctor about the best ways for you to cope with heat. It’s also essential to know the signs of heat-related illnesses, which range from heat rash and sunburn to heat cramps, heat exhaustion, and heat stroke. This chart from the Centers for Disease Control and Prevention describes the signs to look for and what you can do, particularly when heat becomes an emergency.
