PULMICORT FLEXHALER

1 INDICATIONS AND USAGE 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.

2 DOSAGE AND ADMINISTRATION 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. For oral inhalation only. • Patients 18 Years of Age and Older: For patients 18 years of age and older, the recommended starting dosage is 360 mcg twice daily. In some adult patients, a starting dose of 180 mcg twice daily may be adequate. The maximum dosage should not exceed 720 mcg twice daily ( 2.1 ) • Patients 6 to 17 Years of Age: The recommended starting dosage is 180 mcg twice daily. In some pediatric patients, a starting dose of 360 mcg twice daily may be appropriate. The maximum dosage should not exceed 360 mcg twice daily ( 2.1 ) 2.1 Asthma If asthma symptoms arise in the period between doses, an inhaled, short-acting beta 2 -agonist should be taken for immediate relief. Patients 18 Years of Age and Older: For patients 18 years of age and older, the recommended starting dosage is 360 mcg twice daily. In some adult patients, a starting dose of 180 mcg twice daily may be adequate. The maximum dosage should not exceed 720 mcg twice daily. Patients 6 to 17 Years of Age: The recommended starting dosage is 180 mcg twice daily. In some pediatric patients, a starting dose of 360 mcg twice daily may be appropriate. The maximum dosage should not exceed 360 mcg twice daily. For all patients, it is desirable to titrate to the lowest effective dose after adequate asthma stability is achieved. Improvement in asthma control following inhaled administration of budesonide can occur within 24 hours of initiation of treatment, although maximum benefit may not be achieved for 1 to 2 weeks, or longer. Individual patients will experience a variable onset and degree of symptom relief. If a previously effective dosage regimen of PULMICORT FLEXHALER fails to provide adequate control of asthma, the therapeutic regimen should be re-evaluated and additional therapeutic options (e.g., replacing the lower strength of PULMICORT FLEXHALER with the higher strength or initiating oral corticosteroids) should be considered.

4 CONTRAINDICATIONS The use of PULMICORT FLEXHALER is contraindicated in the following conditions: • Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required. • Severe hypersensitivity to milk proteins or any ingredients of PULMICORT FLEXHALER [see Warnings and Precautions (5.3) , Description (11) ]. Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required ( 4 ) Severe hypersensitivity to milk proteins and any of the ingredients in PULMICORT FLEXHALER ( 4 )

5 WARNINGS AND PRECAUTIONS • 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.

7 DRUG INTERACTIONS • Strong Cytochrome P450 3A4 Inhibitors (e.g., ritonavir): Use with caution. May cause increased systemic corticosteroid effects ( 5.7 , 7.1 ) 7.1 Inhibitors of Cytochrome P450 3A4 The main route of metabolism of corticosteroids, including budesonide, is via cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4). After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally administered budesonide increased. Concomitant administration of CYP3A4 may inhibit the metabolism of, and increase the systemic exposure to, budesonide. Caution should be exercised when considering the co-administration of PULMICORT FLEXHALER with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.7) ] .

6 ADVERSE REACTIONS Systemic and inhaled corticosteroid use may result in the following: • Candida albicans Infection [see Warnings and Precautions (5.1) ] • Hypersensitivity Including Anaphylaxis [see Warnings and Precautions (5.3) ] • Immunosuppression [see Warnings and Precautions (5.4) ] • Hypercorticism and Adrenal Suppression [see Warnings and Precautions (5.6) ] • Reduction in Bone Mineral Density [see Warnings and Precautions (5.8) ] • Growth Effects [see Warnings and Precautions (5.9) , Use in Specific Populations (8.4) ] • Glaucoma and Cataracts [see Warnings and Precautions (5.10) ] • Eosinophilic Conditions and Churg-Strauss [see Warnings and Precautions (5.12) ] Most common adverse reactions (incidence ≥1%) are nasopharyngitis, nasal congestion, pharyngitis, rhinitis allergic, viral upper respiratory tract infection, nausea, viral gastroenteritis, otitis media, oral candidiasis ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact the Safety Call Center at 1-888-994-8116 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. PULMICORT FLEXHALER Patients 6 years and older The incidence of common adverse reactions in Table 1 is based upon pooled data reported in patients treated with PULMICORT FLEXHALER 180 or 90 mcg in two double-blind, placebo-controlled clinical trials in which 226 patients (106 females and 120 males) with mild to moderate asthma, previously receiving bronchodilators, inhaled corticosteroids, or both, were treated with PULMICORT FLEXHALER, administered as 360 mcg twice daily for 12 weeks. In these trials, the patients on PULMICORT FLEXHALER had a mean age of 28 years (range 6-80 years) and were predominantly Caucasian (59.7%) and Asian (31.4%). Table 1 includes all adverse reactions (regardless of investigator causality assessment) that occurred at a rate of ≥1% in the PULMICORT FLEXHALER group and more commonly than the placebo group. Table 1 - Adverse Reactions occurring at an incidence of ≥1% and more commonly than placebo in the PULMICORT FLEXHALER group: pooled data from two 12-week, double-blind, placebo-controlled clinical asthma trials in patients 6 years and older Adverse Event PULMICORT FLEXHALER 360 mcg twice daily N=226 % Placebo N=230 % Nasopharyngitis 9.3 8.3 Nasal congestion 2.7 0.4 Pharyngitis 2.7 1.7 Rhinitis allergic 2.2 1.3 Viral upper respiratory tract infection 2.2 1.3 Nausea 1.8 0.9 Viral gastroenteritis 1.8 0.4 Otitis media 1.3 0.9 Oral candidiasis 1.3 0.4 Average exposure duration (days) 76.2 68.2 Long-Term Safety in Patients 6 years of age and older Non-placebo controlled long-term studies in children (at doses up to 360 mcg daily), and adolescent and adult subjects (at doses up to 720 mcg daily), treated for up to one year with PULMICORT FLEXHALER, revealed a similar pattern and incidence of adverse events. PULMICORT TURBUHALER; a different PULMICORT DPI The following adverse reactions occurred in placebo-controlled clinical trials with similar or lower doses with inhaled budesonide via a different PULMICORT dry powder inhaler with an incidence of ≥1% in the budesonide group and were more common than in the placebo group: ≥3%: respiratory infection, sinusitis, headache, pain, back pain, fever. ≥1-3%: neck pain, syncope, abdominal pain, dry mouth, vomiting, weight gain, fracture, myalgia, hypertonia, migraine, ecchymosis, insomnia, infection, taste perversion, voice alteration. Higher doses of inhaled budesonide (800 mcg twice daily) via a different PULMICORT dry powder inhaler resulted in an increased incidence of voice alteration, flu syndrome, dyspepsia, gastroenteritis, nausea, and back pain, compared with doses of 400 mcg twice daily. In a 20-week trial in adult asthmatics who previously required oral corticosteroids, the incidence of adverse reactions was evaluated with 400 mcg twice daily (N=53) and 800 mcg twice daily (N=53) of inhaled budesonide via a different PULMICORT dry powder inhaler and compared with placebo (N=53). In considering these data, the increased average duration of exposure for inhaled budesonide patients (78 days for inhaled budesonide vs. 41 days for placebo) should be taken into account. Adverse reactions, regardless of investigator causality assessment, reported in more than five patients in the budesonide group and which occurred more commonly than the placebo group in decreasing order of frequency include: respiratory infection, sinusitis, headache, oral candidiasis, pain, asthenia, dyspepsia, arthralgia, cough increased, nausea and rhinitis. 6.2 Postmarketing Experience The following adverse reactions have been reported during post-approval use of PULMICORT FLEXHALER. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune system disorders: immediate and delayed hypersensitivity reactions including anaphylactic reaction, angioedema, bronchospasm, rash, contact dermatitis, urticaria, and cough, wheezing or bronchospasm in patients with severe milk protein hypersensitivity [see Warnings and Precautions (5.3) , Contraindications (4) ] Endocrine disorders: symptoms of hypocorticism and hypercorticism [see Warnings and Precautions (5.6) ] Eye disorders: cataracts, glaucoma, increased intraocular pressure [see Warnings and Precautions (5.10) ] Psychiatric disorders: psychiatric symptoms including psychosis, depression, aggressive reactions, irritability, nervousness, restlessness, and anxiety Respiratory, thoracic, and mediastinal disorders: throat irritation Skin and subcutaneous tissue disorders: skin bruising

8.1 Pregnancy Risk Summary There are no adequate well-controlled studies of PULMICORT FLEXHALER in pregnant women. However, there are published studies on the use of budesonide, the active ingredient in PULMICORT FLEXHALER, in pregnant women. In animal reproduction studies, budesonide, administered by the subcutaneous route, caused structural abnormalities, was embryocidal, and reduced fetal weights in rats and rabbits at less than the maximum recommended human daily inhalation dose (MRHDID), but these effects were not seen in rats that received inhaled doses approximately 2 times the MRHDID ( see Data ). Studies of pregnant women have not shown that inhaled budesonide increases the risk of abnormalities when administered during pregnancy. Experience with oral corticosteroids suggests that rodents are more prone to structural abnormalities from corticosteroid exposure than humans. The estimated background risk of major birth defects and miscarriage of the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal risk In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal adverse outcomes such as preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control. Labor or Delivery There are no well-controlled human studies that have investigated the effects of PULMICORT FLEXHALER during labor and delivery. Data Human Data Studies of pregnant women have not shown that inhaled budesonide increases the risk of abnormalities when administered during pregnancy. The results from a large population-based prospective cohort epidemiological study reviewing data from three Swedish registries covering approximately 99% of the pregnancies from 1995-1997 (i.e., Swedish Medical Birth Registry; Registry of Congenital Malformations; Child Cardiology Registry) indicate no increased risk for congenital malformations from the use of inhaled budesonide during early pregnancy. Congenital malformations were studied in 2014 infants born to mothers reporting the use of inhaled budesonide for asthma in early pregnancy (usually 10-12 weeks after the last menstrual period), the period when most major organ malformations occur. The rate of recorded congenital malformations was similar compared to the general population rate (3.8% vs. 3.5%, respectively). In addition, after exposure to inhaled budesonide, the number of infants born with orofacial clefts was similar to the expected number in the normal population (4 children vs. 3.3, respectively). These same data were utilized in a second study bringing the total to 2534 infants whose mothers were exposed to inhaled budesonide. In this study, the rate of congenital malformations among infants whose mothers were exposed to inhaled budesonide during early pregnancy was not different from the rate for all newborn babies during the same period (3.6%). Animal Data In a fertility and reproduction study, male rats were subcutaneously dosed for 9 weeks and females for 2 weeks prior to pairing and throughout the mating period. Females were dosed up until weaning of their offspring. Budesonide caused a decrease in prenatal viability and viability in the pups at birth and during lactation, along with a decrease in maternal body-weight gain, at doses 0.1 times the MRHDID (on a mcg/m 2 basis at maternal subcutaneous doses of 20 mcg/kg/day and above). No such effects were noted at a dose 0.03 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 5 mcg/kg/day). In an embryo-fetal development study in pregnant rabbits dosed during the period of organogenesis from gestation days 6-18, budesonide produced fetal loss, decreased fetal weight, and skeletal abnormalities at doses 0.3 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 25 mcg/kg/day). In an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6-15, budesonide produced similar adverse fetal effects at doses approximately 4 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 500 mcg/kg/day). In another embryo-fetal development study in pregnant rats, no structural abnormalities or embryocidal effects were seen at doses approximately 2 times the MRHDID (on a mcg/m 2 basis at maternal inhalation doses up to 250 mcg/kg/day). In a peri-and post-natal development study, rats dosed from gestation day 15 to postpartum day 21, budesonide had no effects on delivery, but did have an effect on growth and development of offspring. Offspring survival was reduced and surviving offspring had decreased mean body weights at birth and during lactation at doses 0.1 times the MRHDID and higher (on a mcg/m 2 basis at maternal subcutaneous doses of 20 mcg/kg/day and higher). These findings occurred in the presence of maternal toxicity.
