RHINOCORT AQUA

RHINOCORT AQUA — budesonide spray, metered
Physicians Total Care, Inc.

1 INDICATIONS AND USAGE

1.1 Treatment of Seasonal or Perennial Allergic Rhinitis

RHINOCORT AQUA Nasal Spray is indicated for the treatment of nasal symptoms of seasonal or perennial allergic rhinitis in adults and children six years of age and older.

2 DOSAGE AND ADMINISTRATION

The recommended starting dosage for adults and children 6 years of age and older is 64 mcg per day administered as one spray per nostril of RHINOCORT AQUA Nasal Spray 32 mcg once daily. Some patients who do not achieve symptom control at the recommended starting dosage may benefit from an increased dosage. The maximum recommended dosage for adults (12 years of age and older) is 256 mcg per day administered as four sprays per nostril once daily of RHINOCORT AQUA Nasal Spray 32 mcg and the maximum recommended dose for pediatric patients (6 to <12 years of age) is 128 mcg per day administered as two sprays per nostril once daily of RHINOCORT AQUA Nasal Spray 32 mcg.

It is always desirable to titrate an individual patient to the minimum effective dosage to reduce the possibility of side effects. An improvement in nasal symptoms may be noted in patients within 10 hours of first using RHINOCORT AQUA Nasal Spray, however, clinical improvement usually takes 1-2 days with maximum benefit in approximately 2 weeks. When the maximum benefit has been achieved and symptoms have been controlled, reducing the dosage may be effective in maintaining control of the allergic rhinitis symptoms in patients who were initially controlled on higher dosages.

Prior to initial use, the container must be shaken gently and the pump must be primed by actuating eight times. If used daily, the pump does not need to be reprimed. If not used for two consecutive days, reprime with one spray or until a fine spray appears. If not used for more than 14 days, rinse the applicator and reprime with two sprays or until a fine spray appears. Shake the container gently before each use.

Illustrated Patient’s Instructions for Use accompany each package of RHINOCORT AQUA 32 mcg.

3 DOSAGE FORMS and STRENGTHS

RHINOCORT AQUA Nasal Spray is a nasal spray suspension. Each spray delivers 32 mcg of budesonide. Each bottle of RHINOCORT AQUA Nasal Spray 32 mcg contains 120 metered sprays after initial priming.

4 CONTRAINDICATIONS

RHINOCORT AQUA Nasal Spray is contraindicated in patients with hypersensitivity to any of its ingredients [see Warnings and Precautions (5.2) ].

5 WARNINGS AND PRECAUTIONS

5.1 Local Nasal Effects

Epistaxis

In clinical studies of 3 to 52 weeks’ duration epistaxis was observed more frequently in patients treated with RHINOCORT AQUA Nasal Spray than those who received placebo [see Adverse Reactions (6.1) ].

Candida Infection

In clinical studies with budesonide administered intranasally, the development of localized infections of the nose and pharynx with Candida albicans has occurred. When such an infection develops, it may require treatment with appropriate local or systemic therapy and discontinuation of treatment with RHINOCORT AQUA Nasal Spray. Patients using RHINOCORT AQUA Nasal Spray over several months or longer should be examined periodically for evidence of Candida infection or other signs of adverse effects on the nasal mucosa.

Nasal Septal Perforation

Instances of nasal septum perforation have been reported following the intranasal application of corticosteroids, including budesonide [see Adverse Reactions (6.2)].

Impaired Wound Healing

Because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal septal ulcers, nasal surgery, or nasal trauma should not use a nasal corticosteroid until healing has occurred.

5.2 Hypersensitivity Reactions Including Anaphylaxis

Hypersensitivity reactions including anaphylactic reaction, urticaria, rash, dermatitis, angioedema and pruritus may occur [see Contraindications (4) and Adverse Reactions, Post-marketing Experience (6.2)].

5.3 Immunosuppression

Patients who are on drugs that suppress the immune system are more susceptible to infections 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 such 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 affect 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 clinical course of chicken pox or measles infection in patients on intranasal or inhaled corticosteroids has not been studied. While there is no data with intranasal corticosteroids, a clinical study has examined the immune responsiveness to the varicella vaccine in asthma patients 12 months to 8 years of age who were treated 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., beta2 -agonists, leukotriene receptor antagonists, or cromones). The percentage of patients developing a seroprotective antibody titer ≥ 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-corticosteroids asthma therapy (90%). No patient treated with budesonide inhalation suspension developed chicken pox as a result of vaccination.

Corticosteroids should be used with caution, if at all, in patients with active or quiescent tuberculosis infection, untreated fungal, bacterial, systemic viral or parasitic infections; or ocular herpes simplex.

5.4 Hypothalamic-Pituitary-Adrenal Axis Effects

Hypercorticism and Adrenal Suppression: When intranasal steroids are used at higher than recommended dosages or in susceptible individuals at recommended dosages, systemic corticosteroid effects such as hypercorticism and adrenal suppression may appear. If such changes occur, the dosage of RHINOCORT AQUA Nasal Spray should be discontinued slowly, consistent with accepted procedures for discontinuing oral corticosteroid therapy.

The replacement of a systemic corticosteroid with a topical corticosteroid can be accompanied by signs of adrenal insufficiency, and in addition some patients may experience symptoms of corticosteroid withdrawal, e.g., joint and/or muscular pain, fatigue, weakness, nausea, vomiting, hypotension, lassitude, and depression. Patients previously treated for prolonged periods with systemic corticosteroids should be weaned off slowly when transferred to topical corticosteroids and carefully monitored for acute adrenal insufficiency in response to stress. In those patients who have asthma or other clinical conditions requiring long-term systemic corticosteroid treatment, too rapid a decrease in systemic corticosteroids may cause a severe exacerbation of their symptoms.

5.5 Interactions with Strong Cytochrome P450 3A4 Inhibitors

Caution should be exercised when considering the co-administration of RHINOCORT AQUA Nasal Spray 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)].

5.6 Effect on Growth

Intranasal corticosteroids, including budesonide may cause a reduction in growth velocity when administered to pediatric patients. Monitor the growth routinely of pediatric patients receiving long-term treatment with RHINOCORT AQUA Nasal Spray. To minimize the systemic effects of intranasal corticosteroids, including RHINOCORT AQUA Nasal Spray, titrate each patient’s dosage to the lowest one that effectively controls his/her symptoms [see Use in Specific Populations, Pediatric Use (8.4) ].
