Dupixent (dupilumab) treats many health problems. This guide is about using it for chronic obstructive pulmonary disease, or COPD, in adults.

Dupixent is an add-on medicine. You may take it if inhalers alone don't control your COPD symptoms well enough. It's for people with a higher-than-normal level of a type of white blood cell called eosinophils.

Dupixent is a “biologic” medicine. It works with your immune system to block two proteins (called IL-4 and IL-13) that cause swelling inside your body.

Note: Dupixent will not stop a sudden breathing attack. It does not work fast enough for that.

Starting a new medicine can feel stressful. It's OK to feel worried. It's also OK if you just want to get started. Learning how to take Dupixent the right way can help you feel more in control of your COPD and your care.

Managing COPD works best as a team effort. Your doctor knows the medicine. You know your body, your life, and what matters to you. Sharing both sides helps build the best plan.

This guide will help you talk with your care team. Sharing your health history and asking questions are two of the best ways to make sure your treatment plan is safe and right for you.

Some people think the doctor should do all the talking. That's not true. Patients who ask questions and speak up tend to do better because they know what to expect once they get home.

To understand your treatment

Medical words can be confusing. If your doctor uses a word you don't know, ask them to explain it in plain words. When you understand how your medicine works, you can leave your visit feeling confident instead of confused.

To handle side effects

Ask your doctor what side effects to expect and when you should call the office. Knowing what's normal and what's not helps you stay in control. It also helps your care team act fast if something is wrong.

To deal with costs

Cost is a real worry for a lot of people, and it's OK to bring it up. Ask about insurance coverage, approvals, and savings programs during your visit. This gives the office time to work out the paperwork, so it doesn't slow down your treatment. (See “Getting Help With Cost” later in this guide.)

Here are some important questions to ask and why each one matters.

How do I take Dupixent the right way?

Dupixent is given as a shot under the skin. The usual dose is 300 milligrams every two weeks.

Your care team will teach you, or a caregiver, how to safely give the shot. You can give it in your stomach area or thigh. If someone else gives it to you, they can also use the back of your upper arm.

Change the injection spot each time. This helps prevent pain and scarring, and it helps the medicine work its best.

Before your shot, take the syringe or pen out of the fridge. Let it warm up to room temperature first. This takes about 45 minutes.

How does Dupixent come?

Dupixent comes as a prefilled syringe or a prefilled pen. Each one holds a single dose.

How do I store Dupixent?

Keep Dupixent in the refrigerator. Once you take it out, use it within two weeks. If you don't use it by then, throw it away.

What happens if I miss a dose?

Life is unpredictable. You might travel, get sick, or simply forget.

  • If it's been seven days or less since your missed dose, take it as soon as you can. Then go back to your normal schedule.
  • If it's been more than seven days, take it as soon as you can. Then start a new schedule from that date.

How long do people usually stay on this medicine?

There's no set end date. You may stay on Dupixent as long as it's working and you feel OK taking it. Your doctor will check on your progress regularly and talk with you about what to expect, including planning around cost.

What are the most common side effects of Dupixent?

The most common side effects are:

Does Dupixent interact with my other medicines?

There are no known drug interactions with Dupixent.

Your doctor needs to know about your health history to make sure Dupixent is right for you.

Are you due for any vaccinations?

Your doctor will want you to get all your recommended vaccines before you start Dupixent.

Don't get live vaccines while taking Dupixent. Live vaccines use a weakened virus or bacteria. We don't yet know how Dupixent affects these vaccines.

Do you use inhaled steroids?

Your doctor will talk with you about your steroid inhaler (also called a glucocorticoid). Don't stop using it suddenly. If it makes sense, your doctor will help you lower the dose slowly over time.

Are you pregnant, or could you become pregnant?

We don't know if Dupixent can harm a fetus. The baby may be exposed to the medicine. Your doctor can help you decide what's best for you and your baby.

Are you breastfeeding?

We don't know if Dupixent passes into breast milk. Talk with your doctor to make the right choice for you and your baby.

Most side effects are mild and easy to manage. But some need fast action. Call your care team or get emergency help if you notice:

  • Signs of an allergic reaction
  • Trouble breathing
  • Pink eye, or irritation in the front of your eye or eyelid
  • Joint pain or swelling
  • COPD symptoms getting worse

If cost is a concern, you're not alone. Here's where to turn:

  • Ask your care team, or visit Dupixent.com (look for Patient Support, Cost and Savings)
  • Ask if you qualify for a copay savings program if you have private insurance
  • Ask your clinic if a social worker or financial counselor can help you find nonprofit groups that help pay for treatment

Put your most important questions first

Visits are often short. Write down your top three concerns and bring them up early, so you don't run out of time.

Bring a full list of your medicines

Include prescriptions, over-the-counter medicines, vitamins, and supplements. This helps your doctor check for anything that could affect your Dupixent treatment.

Use the “teach-back” technique

After your doctor explains something, say it back in your own words. This helps make sure you understand it. For example: “So I take Dupixent as a shot under the skin every two weeks?” This simple step helps make sure you and your doctor are on the same page before you leave.

Ask for a written summary

Most clinics can print or email you an “After-Visit Summary.” It lists your medicines, how to take them, and the plan you agreed on, so you have something to look back at once you're home.

Good COPD care starts with good communication. Use this guide to share important information with your doctor and to leave each visit knowing what to do next. A patient who speaks up, and a doctor who listens, make the best team.
