Uses for budesonide and formoterol
Budesonide and formoterol is a combination of two medicines that are used to help control the symptoms of asthma and improve lung function. It is used when a patient's asthma has not been controlled sufficiently on other asthma medicines, or when a patient's condition is so severe that more than one medicine is needed every day. Budesonide and formoterol will not relieve an asthma attack that has already started.
Budesonide and formoterol is also used to treat air flow blockage and reduce the worsening of chronic obstructive pulmonary disease (COPD). This includes chronic bronchitis and emphysema.
Inhaled budesonide belongs to the family of medicines known as corticosteroids (cortisone-like medicines). It works by preventing inflammation (swelling) in the lungs that causes an asthma attack.
Inhaled formoterol belongs to the family of medicines known as bronchodilators. It works by helping the muscles around the airways in your lungs stay relaxed to prevent asthma symptoms, such as wheezing and shortness of breath. This increases the flow of air through the bronchial tubes.
Budesonide and formoterol is available only with your doctor's prescription.
Before using budesonide and formoterol
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For budesonide and formoterol, the following should be considered:

Proper use of budesonide and formoterol
Inhaled fluticasone and salmeterol is used to prevent asthma attacks and treat chronic obstructive pulmonary disease (COPD). It is not used to relieve an asthma attack that has already started. For relief of an asthma attack that has already started, you should use another medicine. If you do not have another medicine to use for an attack or if you have any questions about this, check with your doctor.
Budesonide and formoterol is used with a special inhaler and usually comes with a patient information leaflet or patient instructions. Read the directions carefully before using budesonide and formoterol. If you do not understand the directions or you are not sure how to use the inhaler, ask your doctor or pharmacist to show you what to do. Also, ask your doctor to check regularly how you use the inhaler to make sure you are using it properly.
Use budesonide and formoterol only as directed by your doctor. Do not use more of it and do not use it more often than your doctor ordered. Also, do not stop using budesonide and formoterol without telling your doctor first. To do so may increase the chance of side effects. The full benefit of budesonide and formoterol may take 1 to 2 weeks or longer to achieve.
In order for budesonide and formoterol to help prevent asthma attacks, it must be used every day in regularly spaced doses, as ordered by your doctor.
When you use the inhaler for the first time, or if you have not used it for 7 days or longer, or if the inhaler has been dropped, it may not deliver the right amount of medicine with the first inhalation. Therefore, before using the inhaler, prime it by spraying the medicine 2 times into the air away from the face, and shaking it well for 5 seconds before each spray.
How to use budesonide and formoterol:
- Take the inhaler out of the moisture-protective foil pouch before you use it for the first time.
- Do not use the inhaler for budesonide and formoterol with any other medicine.
- Prime the inhaler before use by shaking the inhaler well for 5 seconds and then releasing a test spray. Once again, shake the inhaler and release a second test spray.
- Breathe out to the end of a normal breath (exhale). Do not breathe into the inhaler.
- Put the mouthpiece fully into your mouth and close your lips around it. Do not block the mouthpiece with your teeth or tongue.
- While pressing down firmly and fully on the grey top of the inhaler, breathe in through your mouth as deeply as you can until you have taken a full deep breath.
- Hold your breath and remove the mouthpiece from your mouth. Continue holding your breath for as long as you can up to 10 seconds before breathing out slowly. This gives the medicine time to settle in your airways and lungs.
- Release your finger from the grey top and then turn your head away from the inhaler. Breathe out slowly to the end of a normal breath. Do not breathe into the inhaler.
- Shake the inhaler again for 5 seconds and take the second inhalation following exactly the same steps you used for the first inhalation.
- Replace the mouthpiece cover after using the medicine.
- Gargle and rinse your mouth with water after each dose. This will help prevent hoarseness, throat irritation, and infection in the mouth. Do not swallow the water after rinsing.
The dose counter at the top of the inhaler will turn yellow when the inhaler has 20 or fewer doses left. Throw the inhaler when it reaches 0, or if it has been 3 months since you last opened the foil pouch.
Clean the inhaler every 7 days by wiping the mouthpiece with a dry cloth. Do not put the inhaler into water or try to take it apart. However, you must use a new inhaler with each refill of your medicine.
The dose of budesonide and formoterol will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of budesonide and formoterol. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions while using budesonide and formoterol
It is very important that your doctor check the progress of you or your child at regular visits to make sure that budesonide and formoterol is working properly and to check for any unwanted effects. You may need to have your eyes checked at regular visits. Be sure to keep all appointments.
Although budesonide and formoterol decreases the number of asthma episodes, it may increase the chances of a severe asthma attack when they do occur. Be sure to read about these risks in the patient information leaflet and talk to your doctor about any questions or concerns that you have.
This should not be the first and only medicine you use for asthma or COPD. It will not stop an asthma attack that has already started. Your doctor may prescribe another medicine for you to use in case of an acute asthma attack or an acute COPD flare-up. If the other medicine does not work as well, tell your doctor right away.
Take all of your COPD medicines as your doctor ordered. If you use any type of corticosteroid medicine to control your breathing, keep using it as ordered by your doctor. Do not change your doses or stop using your medicines without first asking your doctor.
You or your child should not use budesonide and formoterol if your asthma attack has already started or if you already have a severe asthma attack. Your doctor may prescribe another medicine (eg, a short-acting inhaler) for you to use in case of an acute asthma attack. Call your doctor immediately for instructions.
Do not use any other asthma medicine or medicine for breathing problems without talking to your doctor. Budesonide and formoterol should not be used with salmeterol (Serevent®), formoterol (Perforomist™), or arformoterol (Brovana®) inhalers.
Talk to your doctor or get medical care right away if:
- Your or your child's symptoms do not improve after using budesonide and formoterol for 1 week or if they become worse.
- Your short-acting inhaler does not seem to be working as well as usual and you need to use it more often (eg, you use 1 whole canister of your short-acting inhaler in 8 weeks time, or you need to use 4 or more inhalations of your short-acting inhaler for 2 or more days in a row).
- You or your child have a significant decrease in your peak flow when measured as directed by your doctor.
Do not change your dose or stop using your medicine without first asking your doctor.
You may get infections more easily while using budesonide and formoterol. Tell your doctor right away if you or your child have been exposed to someone with chickenpox or measles.
Budesonide and formoterol may cause fungus infection of the mouth or throat (thrush). Tell your doctor right away if you or your child have white patches in the mouth or throat, or pain when eating or swallowing.
Patients with COPD may be more likely to have pneumonia when taking budesonide and formoterol. Check with your doctor if you start having increased sputum (spit) production, change in sputum color, fever, chills, increased cough, or an increase in breathing problems.
Using too much of budesonide and formoterol or using it for a long time may increase your risk of having adrenal gland problems. Talk to your doctor if you or your child have more than one of these symptoms while you are using budesonide and formoterol: darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.
Budesonide and formoterol may cause paradoxical bronchospasm, which may be life-threatening. Check with your doctor right away if you or your child are having a cough, difficulty with breathing, or wheezing.
If you or your child develop a skin rash, hives, or any allergic reaction to budesonide and formoterol, check with your doctor right away.
Budesonide and formoterol may decrease bone mineral density when used for a long time. A low bone mineral density can cause weak bones or osteoporosis. If you have any questions about this, ask your doctor.
Budesonide and formoterol may cause children to grow more slowly than usual. Talk to your child's doctor if you have any concerns.
Budesonide and formoterol may affect blood sugar and potassium levels. If you notice a change in the results of your blood or urine sugar or potassium tests or if you have any questions, check with your doctor.
Your doctor may want you to carry a medical identification (ID) card stating that you or your child are using budesonide and formoterol and that you may need additional medicine during times of emergency, a severe asthma attack or other illness, or unusual stress.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
