Breyna: Uses, Side Effects and Dosage

What is BREYNA?

BREYNA combines an inhaled corticosteroid medicine (ICS), budesonide and a long-acting beta₂-adrenergic agonist (LABA) medicine, formoterol.

• Inhaled corticosteroids help to decrease inflammation in the lungs. Inflammation in the lungs can lead to breathing problems.
• LABA medicines are used in people with chronic obstructive pulmonary disease (COPD) and asthma. LABA medicines help the muscles around the airways in your lungs stay relaxed to prevent symptoms such as wheezing, cough, chest tightness, and shortness of breath. These symptoms can happen when the muscles around the airways tighten. This makes it hard to breathe. In severe cases, wheezing can stop your breathing and may lead to death if not treated right away.

BREYNA is not used to relieve sudden breathing problems and will not replace a rescue inhaler.

BREYNA is used for asthma and COPD as follows:

• Asthma: BREYNA is used to control symptoms of asthma, and prevent symptoms such as wheezing in adults and children ages 6 and older.

  BREYNA contains formoterol. LABA medicines such as formoterol when used alone increase the risk of death and hospitalizations from asthma problems. BREYNA contains an ICS and a LABA. When an ICS and LABA are used together, there is not a significant increased risk in hospitalizations and death from asthma problems. BREYNA is not for adults and children with asthma who are well controlled with an asthma-control medicine, such as a low to medium dose of an ICS. BREYNA is for adults and children with asthma who need both an ICS and LABA medicine.

  It is not known if BREYNA is safe and effective in children less than 6 years of age with asthma.

• COPD: COPD is a long-term (chronic) lung disease that includes chronic bronchitis, emphysema, or both. BREYNA 160 mcg/4.5 mcg is used long-term, as 2 inhalations 2 times each day, to improve symptoms of COPD for better breathing and to reduce the number of flare-ups (the worsening of your COPD symptoms for several days).

Do not use BREYNA:

• to treat sudden severe symptoms of asthma or COPD.
• if you are allergic to any of the ingredients in BREYNA. See the end of this leaflet for a list of ingredients in BREYNA.

Before you use BREYNA, tell your healthcare provider about all of your medical conditions, including if you:

• have heart problems.
• have high blood pressure.
• have seizures.
• have thyroid problems.
• have diabetes.
• have liver problems.
• have osteoporosis.
• have an immune system problem.
• have eye problems such as increased pressure in the eye, glaucoma, or cataracts.
• are allergic to any medicines.
• have any type of viral, bacterial, fungal, or parasitic infection.
• are exposed to chicken pox or measles.

• are pregnant or plan to become pregnant. It is not known if BREYNA may harm your unborn baby.

• are breastfeeding. Budesonide, one of the active ingredients in BREYNA, passes into breast milk. You and your healthcare provider should decide if you will take BREYNA while breastfeeding.

Tell your healthcare provider about all the medicines you take including prescription and over-the-counter medicines, vitamins, and herbal supplements. BREYNA and certain other medicines may interact with each other. This may cause serious side effects. Especially tell your healthcare provider if you take antifungal or anti-HIV medicines.

Know all the medicines you take. Keep a list and show it to your healthcare provider and pharmacist each time you get a new medicine.

How should I use BREYNA?

See the step-by-step instructions for using BREYNA at the end of this Patient Information leaflet. Do not use BREYNA unless your healthcare provider has taught you and you understand everything. Ask your healthcare provider or pharmacist if you have any questions.

• Use BREYNA exactly as prescribed. Do not use BREYNA more often than prescribed. BREYNA comes in 2 strengths. Your healthcare provider has prescribed the strength that is best for you. Note the differences between BREYNA and your other inhaled medications, including the differences in prescribed use and physical appearance.
• Children should use BREYNA with an adult’s help, as instructed by the child’s healthcare provider.
• BREYNA should be taken every day as 2 puffs in the morning and 2 puffs in the evening about 12 hours apart.
• If you miss a dose of BREYNA, you should take your next dose at the same time you normally do.
• Rinse your mouth with water and spit the water out after each dose (2 puffs) of BREYNA. Do not swallow the water. This will help to lessen the chance of getting a fungus infection (thrush) in the mouth and throat.
• If you take too much BREYNA, call your healthcare provider or go to the nearest hospital emergency room right away if you have any unusual symptoms, such as worsening shortness of breath, chest pain, increased heart rate, or shakiness.
• Do not spray BREYNA in your eyes. If you accidentally get BREYNA in your eyes, rinse your eyes with water, and if redness or irritation persists, consult your healthcare provider.
• Do not change or stop any medicines used to control or treat your breathing problems. Your healthcare provider will change your medicines as needed.
• While you are using BREYNA 2 times each day, do not use other medicines that contain a LABA for any reason. Ask your healthcare provider or pharmacist if any of your other medicines are LABA medicines.
• BREYNA does not relieve sudden symptoms. Always have a rescue inhaler medicine with you to treat sudden symptoms. If you do not have a rescue inhaler, call your healthcare provider to have one prescribed for you.

• Call your healthcare provider or get medical care right away if:

  • your breathing problems worsen with BREYNA.
  • you need to use your rescue inhaler medicine more often than usual.
  • your rescue inhaler medicine does not work as well for you at relieving symptoms.
  • your peak flow meter results decrease. Your healthcare provider will tell you the numbers that are right for you.
  • your symptoms do not improve after using BREYNA regularly for 1 week.

What are the possible side effects of BREYNA?

BREYNA may cause serious side effects, including:

• Using too much of a LABA medicine may cause:

• chest pain
• a fast and irregular heartbeat
• tremor

• increased blood pressure
• headache
• nervousness

• Fungal infection in your mouth or throat (thrush). Rinse your mouth with water without swallowing after using BREYNA to help reduce your chance of getting thrush.
• Pneumonia and other lower respiratory tract infections. People with COPD have a higher chance of getting pneumonia and other lung infections. Inhaled corticosteroids may increase the chance of getting pneumonia. Call your healthcare provider if you notice any of these symptoms:

• increase in mucus (sputum) production
• fever
• increased cough

• change in mucus color
• chills
• increased breathing problems

• Immune system effects and a higher chance for infections. Tell your healthcare provider about any signs of infection such as:

• fever
• body aches
• feeling tired
• vomiting

• pain
• chills
• nausea

• Adrenal insufficiency. Adrenal insufficiency is a condition in which the adrenal glands do not make enough steroid hormones. This can happen when you stop taking oral corticosteroid medicines and start inhaled corticosteroid medicine.
• Increased wheezing right after taking BREYNA. Always have a rescue inhaler with you to treat sudden wheezing.
• Serious allergic reactions including rash, hives, swelling of the face, mouth, and tongue, and breathing problems. Call your healthcare provider or get emergency medical care if you get any symptoms of a serious allergic reaction.
• Lower bone mineral density. This can happen in people who have a high chance for low bone mineral density (osteoporosis). Your healthcare provider should check you for this during treatment with BREYNA.
• Slowed growth in children. A child’s growth should be checked regularly while using BREYNA.
• Eye problems including glaucoma and cataracts. You should have regular eye exams while using BREYNA.
• Swelling of your blood vessels. This can happen in people with asthma. Tell your healthcare provider right away if you have:

• a feeling of pins and needles or numbness of your arms or legs
• rash

• flu like symptoms
• pain and swelling of the sinuses

• Decreases in blood potassium levels (hypokalemia).
• Increases in blood sugar levels (hyperglycemia).

The most common side effects of BREYNA include:

People with asthma:

• throat irritation
• upper respiratory tract infection
• inflammation of mucous membranes of the sinuses (sinusitis)
• back pain
• stomach discomfort
• thrush in the mouth and throat. Rinse your mouth with water without swallowing after use to help prevent thrush.

• headache
• throat pain
• flu
• nasal congestion
• vomiting

People with COPD:

• throat irritation
• thrush in the mouth and throat. Rinse your mouth with water without swallowing after use to help prevent thrush.
• infection and inflammation of the mucous membranes of the bronchial tubes (bronchitis)
• inflammation of mucous membranes in the sinuses (sinusitis)
• upper respiratory tract infection

Tell your healthcare provider about any side effect that bothers you or that does not go away.

These are not all the possible side effects of BREYNA.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1‑800‑FDA-1088.

How to Use BREYNA

Follow the instructions below for using BREYNA. You will breathe-in (inhale) the medicine. If you have any questions, ask your doctor or pharmacist.

Preparing your BREYNA inhaler for use

1. 1. Take your BREYNA out of the moisture-protective foil pouch before you use it for the first time and throw the foil away. Write the date that you open the foil pouch on the box.
2. 2. The inhaler comes with a counter (see Figure 1). The counter will count down each time you release a puff of BREYNA. The counter will show the number of inhalations (puffs) left in the canister. The counter will stop counting at zero (“0”).
3. 3. Use the BREYNA canister only with the blue BREYNA inhaler supplied with the product. Parts of the BREYNA inhaler should not be used with parts from any other inhalation product.
4. 4. Shake your BREYNA inhaler well for 5 seconds right before each use. Remove the mouthpiece cover by squeezing gently at both sides, then pulling out (see Figure 2). Check the mouthpiece for foreign objects before use.

Figure 2

1. 5.

   Priming your BREYNA inhaler

   Before you use BREYNA for the first time, you will need to prime it. To prime BREYNA, hold it in the upright position (see Figure 1). Shake the BREYNA inhaler well for 5 seconds. Hold your BREYNA inhaler facing away from you and press down the top of the canister firmly until fully depressed to release a test spray. Then shake it again for 5 seconds and release a second test spray. Your BREYNA inhaler is now primed and ready for use. After you have primed the BREYNA inhaler for the first time, the counter will read 120.

If you do not use your BREYNA inhaler for more than 7 days or if you drop it, you will need to prime again.

2. 12. After you finish taking BREYNA (2 puffs), rinse your mouth with water. Spit out the water. Do not swallow it.

Reading the counter

• The counter shows the number of inhalations (puffs) left in your inhaler.

Counter

• The counter will count down each time you release a puff of medicine (either when priming your BREYNA inhaler or when taking the medicine).

• When the counter reads 20, it is time to call your healthcare provider for a refill.

• It is important that you pay attention to the number of inhalations (puffs) left in your BREYNA inhaler by reading the counter. Throw away BREYNA when the counter shows zero (“0”) or 3 months after you take your BREYNA inhaler out of its foil pouch, whichever comes first. Your BREYNA inhaler may not feel empty and it may continue to operate, but you will not get the right amount of medicine if you keep using it. Use a new BREYNA inhaler and follow the instructions for priming (see instruction 5 above).

How to clean your BREYNA inhaler

Clean the blue mouthpiece of your BREYNA inhaler every 7 days. To clean the mouthpiece:

• Remove the grey mouthpiece cover
• Wipe the inside and outside of the blue mouthpiece opening with a clean, dry cloth
• Replace the mouthpiece cover
• Do not put the BREYNA inhaler into water
• Do not try to take apart your BREYNA inhaler
