Ohtuvayre (ensifentrine) is a twice-daily "maintenance" medicine for adults with chronic obstructive pulmonary disease (COPD). COPD is a long-term lung disease that includes chronic bronchitis, emphysema, or both. A maintenance medicine is one you use every day to help keep symptoms under control, not just when you feel bad.

Ohtuvayre blocks two enzymes (proteins that help run chemical reactions in your body) called phosphodiesterase-3 (PDE3) and phosphodiesterase-4 (PDE4). Blocking PDE3 helps keep the muscles around your airways relaxed. Blocking PDE4 helps calm swelling (inflammation) and irritation in your lungs. Together, this can help ease coughing, shortness of breath, chest tightness, and wheezing.

Ohtuvayre comes as a liquid mixture that you breathe in through a nebulizer, which is a machine that turns liquid medicine into a mist. It is not a rescue medicine. It will not stop a sudden breathing attack, and it does not take the place of your rescue medicine.

If you already use inhalers, adding a machine and a twice-daily treatment can feel like one more thing on a long list. That's a fair reaction. Your care team can teach you the steps to use the medicine properly, and you don't have to figure it out alone.

You know how your breathing feels on good and bad days and how often you reach for your rescue medicine. Your doctor knows how this medicine works and how it fits in with the rest of your COPD care. When you work together, you can build a plan that fits your actual days.

Visits go quickly. This guide points you to the questions most worth asking and explains why each question matters, so you can make the most of the time you and your health care provider have together.

Ohtuvayre asks a little more of you than a quick puff from an inhaler, and a short visit with your health care provider likely won’t be able to cover everything. A few well-chosen questions can save you a lot of guessing at home.

To make the most of a short visit

Your doctor knows this medicine. You know your symptoms and how you feel day-to-day. Starting with your biggest questions means the most important things get cleared up before time runs out.

To catch problems early

Ohtuvayre can affect mood and sleep in some people. That's not what most people expect from a lung medicine. Talking about these possible side effects before you start means you and the people close to you know what to watch for.

To avoid a gap in treatment

Ohtuvayre is a brand-name medicine, and what you pay depends on your insurance coverage. Bringing up insurance approval at the visit lets the office start any paperwork early. Find more details about getting help with medicine costs near the end of this guide.

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

Is Ohtuvayre right for me, and how does it fit with my other COPD medicines?

In studies, many people used other maintenance COPD medicines along with Ohtuvayre. Your doctor knows your history and your whole medicine routine, so ask what will stay the same and what, if anything, will change. That way nothing gets dropped or doubled up by accident.

Does Ohtuvayre work safely with my other medicines and supplements?

Only your care team, who can see your whole medicine list, can check this. That includes prescriptions, over-the-counter products, vitamins, herbal products, and supplements. Bring your entire list to your appointment, and ask whether anything on it needs a closer look.

What side effects should I watch for, and which ones should I call you about?

Side effects were generally uncommon in the studies, but a few matter. Ohtuvayre can affect mood and sleep. In rare cases, it may make breathing worse right after a dose, which can be serious or life-threatening. Ask which side effects or symptoms mean you should call, and who to call or when to get medical help right away.

Can you show me how to use the nebulizer before I leave?

Ohtuvayre only works in one kind of machine: a standard jet nebulizer with a mouthpiece and an air compressor. If you already have a nebulizer, ask whether it is the right kind. If you don't have one, ask who will help you get one. Then ask your care team to watch you prepare and use the medicine in the nebulizer at least once. It's much easier to fix a mistake in the office than at home.

What's my plan if my breathing gets worse, or my rescue medicine isn't helping?

Ohtuvayre is not meant for a sudden breathing attack, and you should not use extra doses if you are having sudden trouble breathing. Ask which of your medicines or inhalers should be used for quick relief of symptoms, when to use them, and what should make you call or get help right away. Deciding this ahead of time means no one has to guess in a hard moment.

How will we know it's working, and how long will I be on it?

Ohtuvayre is a maintenance medicine, so it's meant to be used every day, for the long term, to help reduce symptoms and flare-ups. Ask what improvement to look for and when you'll check in with your health care provider. Do not stop using Ohtuvayre without talking with your health care provider first, even if you feel better. Stopping Ohtuvayre could make your COPD symptoms worse. 

Will my insurance need to approve Ohtuvayre, and can your office help start that?

Coverage for a brand-name medicine depends on your insurance plan, and some plans ask for approval first. Asking at the visit lets the office start the paperwork right away, so there's less waiting between your appointment and your first dose.

Before you start, your doctor will want a clear picture of your health. Honest answers help keep you safe.

Have you ever had an allergic reaction to a medicine or to ensifentrine?

You should not use Ohtuvayre if you're allergic to ensifentrine or anything in it. Tell your doctor about any past reaction to a medicine, even if it seemed mild.

Have you ever had depression, anxiety, trouble sleeping, or thoughts of suicide?

In studies, some people who used Ohtuvayre had mood and sleep problems, including depression, anxiety, and trouble sleeping. A very small number had suicidal thoughts, attempts, or completed suicide. If you have a history of depression or suicidal thoughts or behavior, talk with your doctor to weigh the benefits and risks with you before you start. Be honest, even if it's hard. Your doctor can't help with what they don't know.

It also helps to tell a family member or close friend. They may notice changes in your mood or behavior before you do.

Do you have liver problems?

Your liver helps clear Ohtuvayre from your body. If your liver isn’t working well, more of the medicine can stay in your body, so your doctor will use caution.

Do you have kidney problems?

Your doctor will want to know about kidney problems too. Ohtuvayre hasn't been studied in people with severe kidney problems.

Do you have other medical conditions? 

A small number of people had high blood pressure (hypertension) while taking Ohtuvayre. Tell your health care provider if you have high blood pressure or if you have any heart problems. Other common side effects of Ohtuvayre include back pain, bladder or kidney infection, and diarrhea.

Do you have a rescue medicine at home?

Your doctor will want to be sure you have a medicine that you can use for sudden symptoms and that you know when and how to use it. Ohtuvayre will not replace your rescue medicine.

Are you pregnant, planning to become pregnant, or breastfeeding?

We don't know if Ohtuvayre can harm a fetus. We also don't know if it passes into breast milk or how it might affect a nursing baby or milk production. Your doctor can help you weigh the benefits of breastfeeding and your need for the medicine.

Many side effects are mild. But some need fast action. Call your care team right away or get emergency help if you notice any of these. 

  • Your breathing is getting worse, or you need your rescue medicine more than usual
  • A rescue medicine doesn't relieve your symptoms
  • Thoughts of suicide or dying, or a suicide attempt
  • New or worsening depression
  • New or worsening anxiety
  • Trouble sleeping
  • Acting on dangerous impulses
  • Other new, unusual changes in your mood or behavior 
  • A fast or pounding heartbeat or a bad headache after using more than prescribed

If your breathing suddenly gets worse right after a dose, stop using Ohtuvayre and call your health care provider or get emergency help right away.

If you are thinking about harming yourself, call or text 988 (the Suicide & Crisis Lifeline) or call 911 right away.

If cost is a concern, you have options. Here is where to start:

  • Ask your care team, or visit Ohtuvayre.com (look under Patient Support).
  • Ask if you can use 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.

Start with your top three questions

Visits go fast. Write down the three things you most want to know and ask them first. Good questions might be how the nebulizer fits into your routine, which mood changes to watch for, and what your plan is if your breathing gets worse.

Bring your nebulizer, or its model name

If you can, bring the machine and the compressor. If not, bring a photo or the model name. Then your care team can check that it works with Ohtuvayre and let you practice using the medicine with the nebulizer.

Bring your entire medicine list and how often you use your rescue medicine

List everything you take, including COPD inhalers, over-the-counter products, vitamins, supplements, and herbal products. Jot down how often you've used your rescue medicine lately. It helps your doctor see how your COPD is doing.

Use the "teach-back" technique and ask for a written summary

When your doctor finishes explaining, repeat the plan back in your own words. For example: "So I use Ohtuvayre with my jet nebulizer every morning and evening, and I keep my rescue inhaler for sudden symptoms?" Then ask for an after-visit summary, which many clinics can print or email.

Bring someone along if you can

A family member or friend can help you remember the plan. They can also help watch for changes in your mood or sleep once you start the medicine.

Good COPD care starts with good communication. Use this guide to share important information with your doctor, so you can leave each visit knowing what to do next. The best care happens when you speak up and your doctor listens.
