PULMICORT FLEXHALER is a corticosteroid indicated for: • Maintenance treatment of asthma as prophylactic therapy in adult and pediatric patients six years of age or older (1)

Limitations of Use: Not indicated for the relief of acute bronchospasm (1) 1.1 Treatment of Asthma

PULMICORT FLEXHALER is indicated for the maintenance treatment of asthma as prophylactic therapy in patients six years of age or older.

Limitations of Use: • PULMICORT FLEXHALER is NOT indicated for the relief of acute bronchospasm.

The use of PULMICORT FLEXHALER is contraindicated in the following conditions:

1. Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required.
2. Severe hypersensitivity to milk proteins or any ingredients of PULMICORT FLEXHALER [see Warnings and Precautions (5.3), Description (11)].

Systemic and inhaled corticosteroid use may result in the following:

1. Candida albicansInfection [see Warnings and Precautions (5.1)]
2. Hypersensitivity Including Anaphylaxis [see Warnings and Precautions (5.3)]
3. Immunosuppression [see Warnings and Precautions (5.4)]
4. Hypercorticism and Adrenal Suppression [see Warnings and Precautions (5.6)]
5. Reduction in Bone Mineral Density [see Warnings and Precautions (5.8)]
6. Growth Effects [see Warnings and Precautions (5.9) , Use in Specific Populations (8.4)]
7. Glaucoma and Cataracts [see Warnings and Precautions (5.10)]
8. Eosinophilic Conditions and Churg-Strauss [see Warnings and Precautions (5.12)]

• Localized Infections: Candida albicans infection of the mouth and throat may occur. Monitor patients periodically for signs of adverse effects on the oral cavity. Advise patients to rinse the mouth following inhalation (5.1)

• Deterioration of Asthma or Acute Episodes: PULMICORT FLEXHALER should not be used for relief of acute symptoms. Patients require immediate re-evaluation during rapidly deteriorating asthma (5.2)

• Hypersensitivity Reactions: Anaphylaxis, rash, contact dermatitis, urticaria, angioedema, and bronchospasm have been reported with use of PULMICORT FLEXHALER. Discontinue PULMICORT FLEXHALER if such reactions occur (5.3)

• Immunosuppression: Potential worsening of infections (e.g., existing tuberculosis, fungal, bacterial, viral, or parasitic infection; or ocular herpes simplex). Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients (5.4)

• Transferring Patients from Systemic Corticosteroid Therapy: Risk of impaired adrenal function when transferring from oral steroids. Taper patients slowly from systemic corticosteroids if transferring to PULMICORT FLEXHALER (5.5)

• Hypercorticism and Adrenal Suppression: May occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, reduce PULMICORT FLEXHALER slowly (5.6)

• Reduction in Bone Mineral Density with Long term Administration: Monitor patients with major risk factors for decreased bone mineral content (5.8)

• Effects on Growth: Monitor growth of pediatric patients (5.9)

• Glaucoma and Cataracts: Close monitoring is warranted (5.10)

• Paradoxical Bronchospasm: Discontinue PULMICORT FLEXHALER and institute alternative therapy if paradoxical bronchospasm occurs (5.11)

• Eosinophilic Conditions and Churg-Strauss Syndrome: Be alert to eosinophilic conditions (5.12) 5.1 Local Effects

In clinical studies, the development of localized infections of the mouth and pharynx with

Candida albicans

has occurred in patients treated with PULMICORT FLEXHALER. When such an infection develops, it should be treated with appropriate local or systemic (i.e., oral antifungal) therapy while treatment with PULMICORT FLEXHALER continues, but at times, therapy with PULMICORT FLEXHALER may need to be interrupted. Patients should rinse the mouth after inhalation of PULMICORT FLEXHALER. 5.2 Deterioration of Asthma or Acute Episodes

PULMICORT FLEXHALER is not a bronchodilator and is not indicated for the rapid relief of bronchospasm or other acute episodes of asthma. Patients should be instructed to contact their physician immediately if episodes of asthma not responsive to their usual doses of bronchodilators occur during the course of treatment with PULMICORT FLEXHALER. During such episodes, patients may require therapy with oral corticosteroids.

An inhaled short acting beta

2-agonist, not PULMICORT FLEXHALER, should be used to relieve acute symptoms such as shortness of breath. When prescribing PULMICORT FLEXHALER, the physician must also provide the patient with an inhaled, short-acting beta

2-agonist (e.g., albuterol) for treatment of acute symptoms, despite regular twice-daily (morning and evening) use of PULMICORT FLEXHALER. 5.3 Hypersensitivity Reactions Including Anaphylaxis

Hypersensitivity reactions including anaphylaxis, rash, contact dermatitis, urticaria, angioedema, and bronchospasm have been reported with use of PULMICORT FLEXHALER. Discontinue PULMICORT FLEXHALER if such reactions occur

[see

Contraindications (4),

Adverse Reactions (6)].

PULMICORT FLEXHALER contains small amounts of lactose, which contains trace levels of milk proteins. It is possible that cough, wheezing, or bronchospasm may occur in patients who have a severe milk protein allergy

[see

Contraindications (4),

Adverse Reactions (6.2)]. 5.4 Immunosuppression

Patients who are on drugs that suppress the immune system are more susceptible to infection than healthy individuals. Chicken pox and measles, for example, can have a more serious or even fatal course in susceptible children or adults using corticosteroids. In children or adults who have not had these diseases or been properly immunized, particular care should be taken to avoid exposure. How the dose, route, and duration of corticosteroid administration affects the risk of developing a disseminated infection is not known. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If exposed to chicken pox, therapy with varicella zoster immune globulin (VZIG) or pooled intravenous immunoglobulin (IVIG), as appropriate, may be indicated. If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated (see the respective package inserts for complete VZIG and IG prescribing information). If chicken pox develops, treatment with antiviral agents may be considered. The immune responsiveness to varicella vaccine was evaluated in pediatric patients with asthma ages 12 months to 8 years with budesonide inhalation suspension.

An open-label, nonrandomized clinical study examined the immune responsiveness to varicella vaccine in 243 asthma patients 12 months to 8 years of age who were treated with budesonide inhalation suspension 0.25 mg to 1 mg daily (n=151) or non-corticosteroid asthma therapy (n=92) (i.e., beta

2-agonists, leukotriene receptor antagonists, cromones). The percentage of patients developing a seroprotective antibody titer of ≥5.0 (gpELISA value) in response to the vaccination was similar in patients treated with budesonide inhalation suspension (85%), compared to patients treated with non-corticosteroid asthma therapy (90%). No patient treated with budesonide inhalation suspension developed chicken pox as a result of vaccination.

Inhaled corticosteroids should be used with caution, if at all, in patients with active or quiescent tuberculosis infection of the respiratory tract, untreated systemic fungal, bacterial, viral or parasitic infections, or ocular herpes simplex. 5.5 Transferring Patients from Systemic Corticosteroid Therapy

Particular care is needed for patients who are transferred from systemically active corticosteroids to PULMICORT FLEXHALER because deaths due to adrenal insufficiency have occurred in asthmatic patients during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids. After withdrawal from systemic corticosteroids, a number of months are required for recovery of hypothalamic-pituitary-adrenal (HPA) function.

Patients who have been previously maintained on 20 mg or more per day of prednisone (or its equivalent) may be most susceptible, particularly when their systemic corticosteroids have been almost completely withdrawn.

During this period of HPA suppression, patients may exhibit signs and symptoms of adrenal insufficiency when exposed to trauma, surgery, or infection (particularly gastroenteritis) or other conditions associated with severe electrolyte loss. Although PULMICORT FLEXHALER may provide control of asthma symptoms during these episodes, in recommended doses it supplies less than normal physiological amounts of glucocorticoid systemically and does NOT provide the mineralocorticoid activity that is necessary for coping with these emergencies.

During periods of stress or a severe asthma attack, patients who have been withdrawn from systemic corticosteroids should be instructed to resume oral corticosteroids (in large doses) immediately and to contact their physicians for further instruction. These patients should also be instructed to carry a medical identification card indicating that they may need supplementary systemic corticosteroids during periods of stress or a severe asthma attack.

Patients requiring oral corticosteroids should be weaned slowly from systemic corticosteroid use after transferring to PULMICORT FLEXHALER. Prednisone reduction can be accomplished by reducing the daily prednisone dose by 2.5 mg on a weekly basis during therapy with PULMICORT FLEXHALER. Lung function (mean forced expiratory volume in 1 second [FEV

1] or morning peak expiratory flow [PEF]), beta-agonist use, and asthma symptoms should be carefully monitored during withdrawal of oral corticosteroids. In addition to monitoring asthma signs and symptoms, patients should be observed for signs and symptoms of adrenal insufficiency such as fatigue, lassitude, weakness, nausea and vomiting, and hypotension.

Transfer of patients from systemic corticosteroid therapy to PULMICORT FLEXHALER may unmask allergic conditions previously suppressed by the systemic corticosteroid therapy, (e.g., rhinitis, conjunctivitis, eczema, arthritis, eosinophilic conditions). Some patients may experience symptoms of systemically active corticosteroid withdrawal (e.g., joint and/or muscular pain, lassitude, depression) despite maintenance or even improvement of respiratory function. 5.6 Hypercorticism and Adrenal Suppression

PULMICORT FLEXHALER will often help control asthma symptoms with less suppression of HPA function than therapeutically equivalent oral doses of prednisone. Since budesonide is absorbed into the circulation and can be systemically active at higher doses, the beneficial effects of PULMICORT FLEXHALER in minimizing HPA dysfunction may be expected only when recommended dosages are not exceeded and individual patients are titrated to the lowest effective dose. Since individual sensitivity to effects on cortisol production exists, physicians should consider this information when prescribing PULMICORT FLEXHALER.

Because of the possibility of systemic absorption of inhaled corticosteroids, patients treated with PULMICORT FLEXHALER should be observed carefully for any evidence of systemic corticosteroid effects. Particular care should be taken in observing patients postoperatively or during periods of stress for evidence of inadequate adrenal response.

It is possible that systemic corticosteroid effects such as hypercorticism and adrenal suppression (including adrenal crisis) may appear in a small number of patients, particularly when budesonide is administered at higher than recommended doses over prolonged periods of time. If such effects occur, the dosage of PULMICORT FLEXHALER should be reduced slowly, consistent with accepted procedures for reducing systemic corticosteroids and for management of asthma symptoms. 5.7 Interactions with Strong Cytochrome P450 3A4 Inhibitors

Caution should be exercised when considering the co-administration of PULMICORT FLEXHALER with ketoconazole, and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) because adverse effects related to increased systemic exposure to budesonide may occur

[see

Drug Interactions (7.1),

Clinical Pharmacology (12.3)]. 5.8 Reduction in Bone Mineral Density

Decreases in bone mineral density (BMD) have been observed with long-term administration of products containing inhaled corticosteroids. The clinical significance of small changes in BMD with regard to long-term consequences such as fracture is unknown. Patients with major risk factors for decreased bone mineral content, such as prolonged immobilization, family history of osteoporosis, post menopausal status, tobacco use, advance age, poor nutrition, or chronic use of drugs that can reduce bone mass (e.g., anticonvulsants, oral corticosteroids) should be monitored and treated with established standards of care. 5.9 Effects on Growth

Orally inhaled corticosteroids, including budesonide, may cause a reduction in growth velocity when administered to pediatric patients. Monitor the growth of pediatric patients receiving PULMICORT FLEXHALER routinely (e.g., via stadiometry). To minimize the systemic effects of orally inhaled corticosteroids, including PULMICORT FLEXHALER, titrate each patient’s dose to the lowest dosage that effectively controls his/her symptoms

[see

Dosage and Administration (2.1),

Use in Specific Populations (8.4)]. 5.10 Glaucoma and Cataracts

Glaucoma, increased intraocular pressure, and cataracts have been reported following the long-term administration of inhaled corticosteroids, including budesonide. Therefore, close monitoring is warranted in patients with a change in vision or with a history of increased intraocular pressure, glaucoma, and/or cataracts. 5.11 Paradoxical Bronchospasm and Upper Airway Symptoms

As with other inhaled asthma medications, PULMICORT FLEXHALER can produce paradoxical bronchospasm, which may be life threatening. If paradoxical bronchospasm occurs following dosing with PULMICORT FLEXHALER, it should be treated immediately with an inhaled, short-acting beta

2-bronchodilator. PULMICORT FLEXHALER should be discontinued immediately, and alternative therapy should be instituted. 5.12 Eosinophilic Conditions and Churg-Strauss Syndrome

In rare cases, patients on inhaled corticosteroids may present with systemic eosinophilic conditions. Some of these patients have clinical features of vasculitis consistent with Churg-Strauss syndrome, a condition that is often treated with systemic corticosteroid therapy. These events usually, but not always, have been associated with the reduction and/or withdrawal of oral corticosteroid therapy following the introduction of inhaled corticosteroids. Physicians should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients. A causal relationship between budesonide and these underlying conditions has not been established.

PULMICORT FLEXHALER should be administered twice daily by the orally inhaled route only. After inhalation, the patient should rinse the mouth with water without swallowing [see Patient Counseling Information (17.1)] .

Patients should be instructed to prime PULMICORT FLEXHALER prior to its initial use, and instructed to inhale deeply and forcefully each time the device is used.

The safety and efficacy of PULMICORT FLEXHALER when administered in excess of recommended doses have not been established.

After asthma stability has been achieved, it is desirable to titrate to the lowest effective dosage to reduce the possibility of side effects. For patients who do not respond adequately to the starting dose after 1-2 weeks of therapy with PULMICORT FLEXHALER, increasing the dose may provide additional asthma control.

PULMICORT FLEXHALER is available as a dry powder for inhalation containing budesonide in the following 2 strengths: 90 mcg and 180 mcg. Each inhaler contains 60 or 120 actuations.

Patients should be carefully instructed on the use of this drug product to assure optimal dose delivery. The patient may not sense the presence of any medication entering their lungs when inhaling from PULMICORT FLEXHALER. This lack of sensation does not mean that they did not get the medication. They should not repeat their inhalation even if they did not feel the medication when inhaling [see Patient Information].

Caution should be exercised when considering the co-administration of PULMICORT FLEXHALER with ketoconazole, and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) because adverse effects related to increased systemic exposure to budesonide may occur [see Drug Interactions (7.1), Clinical Pharmacology (12.3)] .
