Although we cannot cure asthma, we can control it. Everyone’s asthma is different, so you and your doctor need to create an asthma treatment plan just for you. This plan will include an Asthma Action Plan that will have information about your asthma triggers and instructions for taking your medicines.
There are three changes in the airways when you have asthma:
This swelling, clogging, and muscle tightening makes your airways smaller or narrower. This makes it harder for air to flow easily through your airways, and it becomes harder to breathe. There are asthma medicines that target these three changes. They open your airways and make it easier to breathe.
There are four types of asthma medicines and treatments:
The difference between these asthma treatments can be confusing. It is important to understand what each treatment does and how they help your asthma. Learning how to use each correctly can you help keep your asthma well-controlled. Always take your medicines as directed by your doctor and follow your Asthma Action Plan.
You take most asthma medicines by breathing them in using an inhaler or nebulizer. An inhaler or nebulizer allows the medicine to go directly to your lungs. But some asthma medicines are in pill form, infusion form, or injectable form.
Inhalers (also called puffers)
There are four types of asthma inhaler devices that deliver medicine: metered dose inhalers (MDI), dry powder inhalers (DPI), breath actuated inhalers, and soft mist inhalers.
For inhalers to work well, you must use them correctly. But 70 to 90% of people who use inhalers make at least one mistake when using their inhaler.1 Inhaler mistakes can lead to uncontrolled asthma. Ask your doctor or nurse to watch you use your inhaler to make sure you are using it correctly.
If you use an MDI, it is best to use a spacer or holding chamber with it. This device attaches to your MDI. It turns the medicine into smaller particles that are easier to inhale.
If an MDI is not easy for you to use, you can also talk with your doctor about a DPI or breath actuated inhaler. These inhalers do not spray medicine out. Instead, you put your mouth around the inhaler’s mouthpiece and breathe in.
A nebulizer machine, or “breathing machine,” turns liquid asthma medicine into a mist. You then breathe in the medicine through a mask or mouthpiece.
Nebulizers may be easier to use than asthma inhalers for some people. Once the nebulizer is set up and ready to use, simply breathe in and out as normal.
A doctor should prescribe a nebulizer and the liquid medicine that goes into it. If prescribed, your insurance company may cover the cost. You can also buy a nebulizer from a pharmacy or durable medical equipment (DME) company. Nebulizers purchased online without a prescription may not meet the standards required by the Food and Drug Administration (FDA). Talk with your doctor about which nebulizer is best for you or your child.
Injectable asthma treatment (biologics) are shots or infusions given every few weeks. Shots may be given at the doctor’s office or self-administered at home using an auto-injector device, depending on the type of treatment.
Infusions are given intravenously at the doctor’s office. This is when a needle attached to a tube is injected into a vein in your arm. The medicine then drips from a bag, through the tube, and into your arm so it goes into your bloodstream.
Asthma treatments work in these ways:
Bronchodilators can be short- or long-acting. If you use short-acting bronchodilators (quick-relief medicines) more than two days a week, talk with your doctor about your asthma control. You may need to make changes to your treatment plan to better control your asthma.
Anti-inflammatories (steroidal) come in many different forms. They are also called controllers because they help to control or prevent asthma symptoms. They reduce swelling and extra mucus inside the airways. They will not relieve sudden symptoms.
Other Types of Medicines and Treatments
Single Maintenance and Reliever Therapy (SMART)
The 2020 Focused Updates to the Asthma Management Guidelines recommends single maintenance and reliever therapy, also known as SMART. SMART uses one inhaler that has two medicines (combination medicine) as a quick-relief and controller medicine. When on SMART, you can either take your medicine only as needed to relieve sudden symptoms, or you can take it daily as a controller and as needed for quick relief. This is based on your age and the severity of your asthma.
There is only one long-acting beta agonist – formoterol – that also works as a quick-relief medicine. It acts quickly to open the airways and relieve sudden symptoms. It also works as a controller by keeping the airways open for up to 12 hours. The guidelines recommend using the combination of budesonide and formoterol found in SYMBICORT©. Formoterol is also available with mometasone furoate in Dulera©.
The FDA has not yet approved these medicines to be used in this way. If you are interested in SMART, talk with your doctor.
Not usually. Although medicines help a lot, they may not be able to do the job alone. You have to avoid the things that cause or trigger your asthma symptoms as much as you can. Asthma triggers can be found outside or inside your home, school, or workplace.
Improving the indoor air quality in your home is an important part of asthma control. Your indoor air can be more polluted than outside air. Our interactive Healthy Home can show you ways to improve the indoor air quality of your home. A healthier home can reduce your exposure to allergens and irritants.
Not always. You will probably take more medicine when you begin treatment to get control of your asthma. Work with your doctor to learn which medicine(s) control your asthma best and how much you need. Once your asthma is well-controlled, your doctor may be able to reduce the amount of medicine you take. The goal is to gain control of your asthma as soon as possible and then control it with as little medicine as possible. Once long-term anti-inflammatory therapy begins, your doctor should monitor you every one to six months. This is to see how your asthma medicines are working and if your asthma is well controlled.
Maybe not. Asthma is a chronic condition (which means you will have it all of your life) that is controllable. Unfortunately, there is no cure for asthma. For that reason, you may have asthma symptoms when exposed to triggers. This is the case even if you don’t have symptoms very often. Your triggers can change over time, and your treatment will depend on two things: how severe your asthma is, and how often you have symptoms. If your asthma is controlled, your treatment will focus on managing symptoms and treatment of episodes when they happen.
If your symptoms happen at certain times and you know what caused them, you and your doctor can use this information to determine the best treatment. If, for example, you have seasonal asthma because of a specific pollen allergy, you may take medicines only when that pollen is in the air. But asthma that specific is not common. Many people with asthma take some form of medicine most or all of the time.
Yes, if you have nighttime asthma symptoms. Many people wake up with asthma symptoms such as coughing or wheezing. You can control nighttime symptoms by taking asthma medicines as directed by your doctor.
Removing triggers where you sleep may help you sleep better. Many people are allergic to dust mites and mold found in bedding materials. Using mattress or pillow encasements can help contain those allergens. Dehumidifiers can also be helpful to reduce the humidity in your home that dust mites and mold need to exist. Using air cleaners in your bedroom may also help reduce your exposure to allergens and irritants (animal dander, dust mites, air pollution, etc.).
Yes. Exercising, particularly in cold air, may cause airway swelling or exercise-induced bronchoconstriction (EIB). Quick-relief asthma medicines, taken before exercise, usually control this. If you need repeated doses of quick-relief medicine during and after exercise talk with your doctor. Your medicines may need to be adjusted. Thanks to these medicines, many Olympic and professional athletes have successful sports careers even with their asthma.
It is important for everyone, including people with asthma, to be as active as possible for good health. Talk with your doctor about how you can be physically active while keeping your asthma well-controlled.
Yes. All medicines have side effects. Tell your doctor how you are responding to the treatment and if you have any side effects. Follow up often with your doctor so you can control your asthma with the least amount of medicines and with the fewest side effects.
