NASACORT AQ Nasal Spray is indicated for the treatment of the nasal symptoms of seasonal and perennial allergic rhinitis in adults and children 2 years of age and older.
DOSAGE AND ADMINISTRATION
Administer NASACORT AQ Nasal Spray by the intranasal route only. Shake NASACORT AQ Nasal Spray well before each use.
Adults and Adolescents 12 Years of Age and Older
The recommended starting and maximum dose is 220 mcg per day as two sprays in each nostril once daily. Titrate an individual patient to the minimum effective dose to reduce the possibility of side effects. When the maximum benefit has been achieved and symptoms have been controlled, reducing the dose to 110 mcg per day (one spray in each nostril once a day) has been shown to be effective in maintaining control of the allergic rhinitis symptoms.
Children 2 to 12 Years of Age
Children 6 to 12 years of age
The recommended starting dose is 110 mcg per day given as one spray in each nostril once daily. Children not responding adequately to 110 mcg per day may use 220 mcg (2 sprays in each nostril) once daily. Once symptoms have been controlled, the dosage may be decreased to 110 mcg once daily [see WARNINGS AND PRECAUTIONS, Use In Specific Populations and CLINICAL PHARMACOLOGY].
Children 2 to 5 years of age
NASACORT AQ Nasal Spray is not recommended for children under 2 years of age.
Prime NASACORT AQ Nasal Spray before using for the first time by shaking the contents well and releasing 5 sprays into the air away from the face. It will remain adequately primed for two weeks. If the product is not used for more than 2 weeks, then it can be adequately reprimed with one spray. Shake NASACORT AQ Nasal Spray well before each use.
If adequate relief of symptoms has not been obtained after 3 weeks of treatment, NASACORT AQ Nasal Spray should be discontinued [see WARNINGS AND PRECAUTIONS, PATIENT INFORMATION, and ADVERSE REACTIONS].
Dosage Forms And Strengths
NASACORT AQ Nasal Spray is a metered-dose pump spray containing the active ingredient triamcinolone acetonide.

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 clinical practice.
In placebo-controlled, double-blind, and open-label clinical studies, 1483 adults and children 12 years and older received treatment with NASACORT AQ Nasal Spray. These patients were treated for an average duration of 51 days. In the controlled trials (2-5 weeks duration) from which the following adverse reaction data are derived, 1394 patients were treated with NASACORT AQ Nasal Spray for an average of 19 days. In a long-term, open-label study, 172 patients received treatment for an average duration of 286 days. Adverse reactions from 12 studies in adults and adolescent patients 12 to 17 years of age receiving NASACORT AQ Nasal Spray 27.5 mcg to 440 mcg once daily are summarized in Table 1.
In clinical trials, nasal septum perforation was reported in one adult patient who received NASACORT AQ Nasal Spray.

A total of 602 children 6 to 12 years of age were studied in 3 double-blind, placebo-controlled clinical trials. Of these, 172 received 110 mcg/day and 207 received 220 mcg/day of NASACORT AQ Nasal Spray for two, six, or twelve weeks. The longest average durations of treatment for patients receiving 110 mcg/day and 220 mcg/day were 76 days and 80 days, respectively. One percent of patients treated with NASACORT AQ were discontinued due to adverse experiences. No patient receiving 110 mcg/day and one patient receiving 220mcg/day discontinued due to a serious adverse event. A similar adverse reaction profile was observed in pediatric patients 6-12 years of age as compared to adolescents and adults with the exception of epistaxis which occurred in less than 2% of the children studied. Adverse reactions from 2 studies in children 4 to 12 years of age receiving NASACORT AQ Nasal Spray 110 mcg once daily are summarized in Table 2.

In the event of accidental overdose, an increased potential for these adverse experiences may be expected, but acute systemic adverse experiences are unlikely [see OVERDOSAGE].
In addition to the adverse drug reactions reported during clinical studies and listed above, the following adverse reactions have been identified during post-approval use of NASACORT AQ Nasal Spray. 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. Reactions that have been reported during post-marketing experience include: nasal discomfort and congestion, sneezing, alterations of taste and smell, nausea, insomnia, dizziness, fatigue, dyspnea, decreased blood cortisol, cataract, glaucoma, increased ocular pressure, pruritus, rash, and hypersensitivity.
No reported drug interactions in the prescribing information.
Included as part of the PRECAUTIONS section.
Local Nasal Effects
Nasal Septal Perforation
In clinical trials, nasal septum perforation was reported in one adult patient treated with NASACORT AQ Nasal Spray.
In clinical studies with NASACORT AQ Nasal Spray, the development of localized infections of the nose and pharynx with Candida albicans has rarely occurred. When such an infection develops it may require treatment with appropriate local or systemic therapy and discontinuation of NASACORT AQ Nasal Spray. Therefore, patients using NASACORT AQ 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.
Impaired Wound Healing
Because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal ulcers, surgery, or trauma should not use NASACORT AQ Nasal Spray until healing has occurred.
Glaucoma and Cataracts
Nasal and inhaled corticosteroids may result in the development of glaucoma and/or cataracts. Therefore, close monitoring is warranted in patients with a change in vision or with a history of increased intraocular pressure, glaucoma and/or cataracts.
Persons who are using drugs that suppress the immune system are more susceptible to infections than healthy individuals. Chickenpox 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 have not 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 chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) 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 chickenpox develops, treatment with antiviral agents may be considered.
Corticosteroids should be used with caution, if at all, in patients with active or quiescent tuberculosis infections of the respiratory tract; untreated local or systemic fungal or bacterial infections; systemic viral or parasitic infections, or ocular herpes simplex because of the potential for worsening of these infections.
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 NASACORT AQ 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. In addition, some patients may experience symptoms of corticosteroid withdrawal, e.g., joint and/or muscular pain, lassitude, and depression. Patients previously treated for prolonged periods with systemic corticosteroids and transferred to topical corticosteroids should be 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, rapid decreases in systemic corticosteroid dosages may cause a severe exacerbation of their symptoms.
Effect on Growth
Corticosteroids, including NASACORT AQ Nasal Spray, may cause a reduction in growth velocity when administered to pediatric patients. Monitor the growth routinely of pediatric patients receiving NASACORT AQ Nasal Spray. To minimize the systemic effects of intranasal corticosteroids, including NASACORT AQ Nasal Spray, titrate each patient's dose to the lowest dosage that effectively controls his/her symptoms [see Use in Specific Populations].
Patient Counseling Information
See FDA-approved patient labeling (PATIENT INFORMATION and Instructions for Use).
Local Nasal Effects
Patients should be informed that treatment with NASACORT AQ Nasal Spray may lead to adverse reactions, which include epistaxis and nasal ulceration. Candida infection may also occur with treatment with NASACORT AQ Nasal Spray. In addition, nasal corticosteroids are associated with nasal septal perforation and impaired wound healing. Patients who have experienced recent nasal ulcers, nasal surgery, or nasal trauma should not use NASACORT AQ Nasal Spray until healing has occurred [see WARNINGS AND PRECAUTIONS].
Cataracts and Glaucoma
Patients should be informed that glaucoma and cataracts are associated with nasal and inhaled corticosteroid use. Patients should inform his/her heath care provider if a change in vision is noted while using NASACORT AQ Nasal Spray [see WARNINGS AND PRECAUTIONS].
Patients who are on immunosuppressant doses of corticosteroids should be warned to avoid exposure to chickenpox or measles and, if exposed, to consult their physician without delay. Patients should be informed of potential worsening of existing tuberculosis, fungal, bacterial, viral or parasitic infections, or ocular herpes simplex [see WARNINGS AND PRECAUTIONS].
Effect on Growth
Parents should be advised that NASACORT AQ Nasal Spray may slow growth in children. A child taking NASACORT AQ Nasal Spray should have his/her growth checked regularly [see WARNINGS AND PRECAUTIONS and Pediatric Use].
Use Daily for Best Effect
Patients should use NASACORT AQ Nasal Spray on a regular once-daily basis for optimal effect. It is also important to shake the bottle well before each use. Do not blow your nose for 15 minutes after using the spray. NASACORT AQ Nasal Spray, like other corticosteroids, does not have an immediate effect on rhinitis symptoms. Although improvement in some patient symptoms may be seen within the first day of treatment, maximum benefit may not be reached for up to one week. The patient should not increase the prescribed dosage but should contact the physician if symptoms do not improve or if the condition worsens.
Keep Spray Out of Eyes
Patients should be informed to avoid spraying NASACORT AQ Nasal Spray in their eyes.
IMPORTANT: Please read these instructions carefully before using your NASACORT®AQ Nasal Spray
Carcinogenesis, Mutagenesis, Impairment of Fertility
In a two-year study in rats, triamcinolone acetonide caused no treatment-related carcinogenicity at oral doses up to 1.0 mcg/kg (less than the maximum recommended daily intranasal dose in adults and children on a mcg/m² basis, respectively). In a two-year study in mice, triamcinolone acetonide caused no treatment-related carcinogenicity at oral doses up to 3.0 mcg/kg (less than the maximum recommended daily intranasal dose in adults and children on a mcg/m² basis, respectively).
No evidence of mutagenicity was detected from in vitro tests (a reverse mutation test in Salmonella bacteria and a forward mutation test in Chinese hamster ovary cells) conducted with triamcinolone acetonide.
In male and female rats, triamcinolone acetonide caused no change in pregnancy rate at oral doses up to 15.0 mcg/kg (less than the maximum recommended daily intranasal dose in adults on a mcg/m² basis). Triamcinolone acetonide caused increased fetal resorptions and stillbirths and decreases in pup weight and survival at doses of 5.0 mcg/kg and above (less than the maximum recommended daily intranasal dose in adults on a mcg/m² basis). At 1.0 mcg/kg (less than the maximum recommended daily intranasal dose in adults on a mcg/m² basis), it did not induce the above mentioned effects.
Use In Specific Populations
Teratogenic Effects - Pregnancy Category C
There are no adequate and well-controlled studies of NASACORT AQ Nasal Spray in pregnant women. Triamcinolone acetonide was teratogenic in rats, rabbits, and monkeys. NASACORT AQ Nasal Spray, like other corticosteroids, should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Since their introduction, experience with oral corticosteroids in pharmacologic as opposed to physiologic doses suggests that rodents are more prone to teratogenic effects from corticosteroids than humans. In addition, because there is a natural increase in glucocorticoid production during pregnancy, most women will require a lower exogenous corticosteroid dose and many will not need corticosteroid treatment during pregnancy.
In reproduction studies in rats and rabbits, triamcinolone acetonide administered by inhalation produced cleft palate and/or internal hydrocephaly and axial skeletal defects at exposures less than and 2 times, respectively, the maximum recommended daily intranasal dose in adults on a mcg/m² basis. In a monkey reproduction study, triamcinolone acetonide administered by inhalation produced cranial malformations at an exposure approximately 37 times the maximum recommended daily intranasal dose in adults on a mcg/m² basis.
It is not known whether triamcinolone acetonide is excreted in human milk. Because other corticosteroids are excreted in human milk, caution should be exercised when NASACORT AQ Nasal Spray is administered to nursing women.
The safety and effectiveness of NASACORT AQ Nasal Spray has been evaluated in 464 children 2 to 5 years of age, 518 children 6 to 12 years of age, and 176 adolescents 12 to 17 years of age [see Clinical Studies]. The safety and effectiveness of NASACORT AQ Nasal Spray in children below 2 years of age have not been established.
Controlled clinical studies have shown that intranasal corticosteroids may cause a reduction in growth velocity in pediatric patients. This effect has been observed in the absence of laboratory evidence of HPA axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA axis function. The long-term effects of reduction in growth velocity associated with intranasal corticosteroids, including the impact on final adult height are unknown. The potential for “catchup” growth following discontinuation of treatment with intranasal corticosteroids has not been adequately studied. The growth of pediatric patients receiving intranasal corticosteroids, including NASACORT AQ Nasal Spray, should be monitored routinely (e.g., via stadiometry). The potential growth effects of treatment should be weighed against the clinical benefits obtained and the risks/benefits of treatment alternatives. To minimize the systemic effects of intranasal corticosteroids, including NASACORT AQ Nasal Spray, each patient's dose should be titrated to the lowest dosage that effectively controls his/her symptoms.
The effect of NASACORT AQ Nasal Spray on growth velocity in children was assessed in a 12 month randomized, placebo controlled study conducted in 299 prepubescent children age 3 to 9 years (173 males, 126 females) with perennial allergic rhinitis. Treatment groups were NASACORT AQ 110 mcg once daily and placebo. Growth velocity was estimated for each patient using the slope of the linear regression of height over time using observed data in the intent to treat population who had at least 3 height measurements after randomization. Growth velocities were significantly lower in the NASACORT AQ group compared to placebo, with a mean growth velocity of 6.09 cm/year in the placebo group and 5.65 cm/year in the NASACORT AQ treated group (difference from placebo -0.45 cm/year; 95% CI: -0.78, -0.11).
Clinical studies of NASACORT AQ did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Chronic overdosage may result in signs/symptoms of hypercorticism [see WARNINGS AND PRECAUTIONS]. There are no data on the effects of acute or chronic overdosage with NASACORT AQ Nasal Spray. Because of low systemic bioavailability and an absence of acute drug-related systemic findings in clinical studies overdose is unlikely to require any therapy other than observation.
Acute overdosing with the intranasal dosage form is unlikely in view of the total amount of active ingredient present and low bioavailability of triamcinolone acetonide. In the event that the entire contents of the bottle were administered all at once, via either oral or nasal application, clinically significant systemic adverse events would most likely not result.
NASACORT AQ should not be administered to patients with a history of hypersensitivity to triamcinolone acetonide or to any of the other ingredients of this preparation.
Mechanism of Action
Triamcinolone acetonide is a synthetic fluorinated corticosteroid with approximately 8 times the potency of prednisone in animal models of inflammation.
Although the precise mechanism of corticosteroid antiallergic action is unknown, corticosteroids have been shown to have a wide range of actions on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, cytokines) involved in inflammation.
In order to determine if systemic absorption plays a role in the effect of NASACORT AQ Nasal Spray on allergic rhinitis symptoms, a two week double-blind, placebo-controlled clinical study was conducted comparing NASACORT AQ, orally ingested triamcinolone acetonide, and placebo in 297 adult patients with seasonal allergic rhinitis. The study demonstrated that the therapeutic efficacy of NASACORT AQ Nasal Spray can be attributed to the topical effects of triamcinolone acetonide.
In order to evaluate the effects of systemic absorption on the Hypothalamic-Pituitary-Adrenal (HPA) axis, 4 clinical studies, one each in adults and in children 6-12 years of age, 2-5 years of age, and 2-11 years of age, were conducted.
The adult clinical study compared 220 mcg or 440 mcg NASACORT AQ per day, or 10 mg prednisone per day with placebo for 42 days. Adrenal response to a six-hour 250 mcg cosyntropin stimulation test showed that NASACORT AQ administered at doses of 220 mcg and 440 mcg had no statistically significant effect on HPA activity versus placebo. Conversely, oral prednisone at 10 mg/day significantly reduced the response to ACTH.
A study evaluating plasma cortisol response thirty and sixty minutes after 250 mcg cosyntropin stimulation in 80 pediatric patients 6 to 12 years of age who received 220 mcg or 440 mcg (twice the maximum recommended daily dose) daily for six weeks was conducted. No abnormal response to cosyntropin infusion (peak serum cortisol < 18 mcg/dL) was observed in any pediatric patient after six weeks of dosing with NASACORT AQ at 440 mcg per day.
In pediatric patients 2 to 5 years of age (n = 61) receiving Nasacort AQ 110 mcg per day intranasally, HPA axis function was assessed by cosyntropin stimulation test; however, the results were inconclusive.
An effect of Nasacort AQ Nasal Spray on adrenal function in children 2 to 5 years of age cannot be ruled out.
In a 6-week trial in 140 children 2 to 11 years of age with allergic rhinitis, a daily dose of 110 or 220 mcg of NASACORT AQ Nasal Spray was compared to placebo nasal spray. A subset of 24 children 6 to 11 years of age received a higher dose of 220 mcg of NASACORT AQ Nasal Spray. A positive control was not included in this trial. Adrenal function was assessed by measurement of 24 hour serum cortisol levels before and after the treatment. The difference from placebo in the change from baseline in LS mean serum cortisol AUC (0-24 hr) at the end of week 6 for the NASACORT AQ Nasal Spray treatment groups (110 mcg and 220 mcg) was -4.2 mcg•hour/dL (95% CI: -14.7, 6.4).
Based upon intravenous dosing of triamcinolone acetonide phosphate ester in adults, the half-life of triamcinolone acetonide was reported to be 88 minutes. The volume of distribution (Vd) reported was 99.5 L (SD ± 27.5) and clearance was 45.2 L/hour (SD ± 9.1) for triamcinolone acetonide. The plasma half-life of corticosteroids does not correlate well with the biologic half-life.
Pharmacokinetic characterization of the NASACORT AQ Nasal Spray formulation was determined in both normal adult subjects and patients with allergic rhinitis. Single dose intranasal administration of 220 mcg of NASACORT AQ Nasal Spray in normal adult subjects and patients demonstrated minimal absorption of triamcinolone acetonide. The mean peak plasma concentration was approximately 0.5 ng/mL (range: 0.1 to 1.0 ng/mL) and occurred at 1.5 hours post dose. The mean plasma drug concentration was less than 0.06 ng/mL at 12 hours, and below the assay detection limit (the minimum LOQ of the assay was 0.025 ng/ml) at 24 hours. The average terminal half-life was 3.1 hours. The range of mean AUC0–∞ values was 1.4 ng•hr/mL to 4.7 ng•hr/mL between doses of 110 mcg to 440 mcg in both patients and healthy volunteers. Dose proportionality was demonstrated in both normal adult subjects and in allergic rhinitis patients following single intranasal doses of 110 mcg or 220 mcg NASACORT AQ Nasal Spray. The Cmax and AUC0-∞ of the 440 mcg dose increased less than proportionally when compared to 110 and 220 mcg doses.
Following multiple dose administration of NASACORT AQ 440 mcg once daily in pediatric patients 6 to 12 years of age, plasma drug concentrations, AUC0-∞, Cmax and Tmax were similar to those values observed in adult patients receiving the same dose. Intranasal administration of NASACORT AQ 110 mcg once daily in pediatric patients 2 to 5 years of age exhibited similar systemic exposure to that achieved in adult patients 20 to 49 years of age with intranasal administration of NASACORT AQ at a dose of 220 mcg once daily. Based on the population pharmacokinetic modeling, the apparent clearance and volume of distribution following intranasal administration of NASACORT AQ in pediatric patients 2 to 5 years of age were found to be approximately half of that in adults.
In animal studies using rats and dogs, three metabolites of triamcinolone acetonide have been identified. They are 6β-hydroxytriamcinolone acetonide, 21-carboxytriamcinolone acetonide and 21-carboxy-6β-hydroxytriamcinolone acetonide. All three metabolites are expected to be substantially less active than the parent compound due to (a) the dependence of anti-inflammatory activity on the presence of a 21-hydroxyl group, (b) the decreased activity observed upon 6-hydroxylation, and (c) the markedly increased water solubility favoring rapid elimination. There appeared to be some quantitative differences in the metabolites among species. No differences were detected in metabolic pattern as a function of route of administration.
Animal Toxicology and/or Pharmacology
Triamcinolone acetonide was teratogenic in rats, rabbits, and monkeys. In rats, triamcinolone acetonide was teratogenic at an inhalation dose of 20 mcg/kg and above (approximately 7/10 of the maximum recommended daily intranasal dose in adults on a mcg/m² basis). In rabbits, triamcinolone acetonide was teratogenic at inhalation doses of 20 mcg/kg and above (approximately 2 times the maximum recommended daily intranasal dose in adults on a mcg/m² basis). In monkeys, triamcinolone acetonide was teratogenic at an inhalation dose of 500 mcg/kg (approximately 37 times the maximum recommended daily intranasal dose in adults on a mcg/m² basis). Dose-related teratogenic effects in rats and rabbits included cleft palate and/or internal hydrocephaly and axial skeletal defects, whereas the effects observed in the monkey were cranial malformations.
Hypoadrenalism may occur in infants born of mothers receiving corticosteroids during pregnancy. Such infants should be carefully observed.
The safety and efficacy of NASACORT AQ Nasal Spray have been evaluated in 10 double-blind, placebo-controlled clinical studies of two-to four-weeks duration in adults and children 12 years and older with seasonal or perennial allergic rhinitis. The number of patients treated with NASACORT AQ Nasal Spray in these studies was 1266; of these patients, 675 were males and 591 were females.
Overall, the results of these clinical studies in adults and children 12 years and older demonstrated that NASACORT AQ Nasal Spray 220 mcg once daily (2 sprays in each nostril), when compared to placebo, provides statistically significant relief of nasal symptoms of seasonal or perennial allergic rhinitis including sneezing, stuffiness, discharge, and itching.
The safety and efficacy of NASACORT AQ Nasal Spray, at doses of 110 mcg or 220 mcg once daily, have also been adequately studied in two double-blind, placebo-controlled studies of two-and twelve-weeks duration in children ages 6 through 12 years with seasonal and perennial allergic rhinitis. These studies included 341 males and 177 females. NASACORT AQ administered at either dose resulted in statistically significant reductions in the severity of nasal symptoms of allergic rhinitis.
The safety and efficacy of NASACORT AQ Nasal Spray in children 2 to 5 years of age with perennial allergic rhinitis with or without seasonal allergic rhinitis was studied in a single 4 week double blind, placebo controlled clinical study with a 24 week open label extension conducted in the United States. The study included 464 patients (266 males and 198 females) 2 to 5 years of age who received at least one dose of study medication (233 placebo, 231 NASACORT AQ 110 mcg once daily). Efficacy was determined over a four-week double-blind, placebo-controlled treatment period and was based on patient's parent or guardian recording of four nasal symptoms (total nasal symptom score, TNSS), congestion, itching, rhinorrhea, and sneezing on a 0-3 categorical severity scale (0=absent, 1=mild, 2=moderate, and 3=severe) once daily. Reflective scoring (rTNSS) required recording symptom severity over the previous 24 hours; the instantaneous scoring (iTNSS) required recording symptom severity at the time just prior to dosing. Baseline symptom severity was comparable between NASACORT AQ and placebo respectively, for iTNSS (7.52, 7.61) and rTNSS (7.96, 7.87). While the 24-hour iTNSS over the 4-week double-blind period was numerically improved with NASACORT AQ (-2.28) vs. placebo (-1.92), the difference was not statistically significant (difference from placebo -0.36; 95% CI [-0.77, 0.06]; p value = 0.095). For the 24-hour rTNSS over the 4 week double-blind treatment period, NASACORT A Q 110 mcg once daily provided statistically significantly greater improvement from baseline (-2.31) versus placebo (-1.87) (difference from placebo 0.44; 95% CI [-0.84, -0.04]; p value = 0.033).

What are the possible side effects of Nasacort AQ?
Common side effects of Nasacort AQ include:
Sore throat, headache, and nosebleeds. If you have an increase in nosebleeds after using Nasacort AQ or the inside of your nose hurts, contact your healthcare provider.
What are the other risks of using Nasacort AQ?
Hole in the cartilage inside the nose (nasal septal perforation). Tell your healthcare provider if you have a whistling sound from your nose when you breathe.

Instructions for Use
Read these instructions carefully before using your Nasacort AQ.
Before using the spray pump bottle:
Pull the blue cover and remove the clip from the spray pump unit. See figure A.
If the top part of the spray pump comes off of the bottle when removing the cover, then re-insert the stem back into the pump.
2. Shake the spray pump bottle before each use.
Priming the Spray Pump Bottle
3. Before using the spray pump bottle for the first time, it must be primed. To prime, put your thumb on the bottom of the bottle and your index and middle fingers on the “shoulders” of the bottle, and hold it upright. See figure B.
4. Point the bottle away from your eyes. Push the bottle up with your thumb and against your two fingers firmly and quickly until a fine spray appears. Do this pumping action 5 times. Now your spray pump bottle is primed and ready for use. A fine mist can only be made by a rapid and firm pumping action.
5. Repeat priming the pump, if it has not been used for more than 2 weeks. To reprime, shake the spray pump bottle and pump it just one time. Now the spray pump bottle is reprimed.
Using the spray:
6. Gently blow your nose to clear it, if needed. For small children, be sure to help them gently blow their nose, as much as possible.
7. Pull off the blue cover and clip as shown in figure C. Shake the spray pump well.
8. Hold the spray pump firmly, with the index and middle finger on either side of the spray tip. Place your thumb on the bottom of the bottle. Be careful so that your fingers will not slip off the spray pump as you spray inside your nose. See figure D.
9. Put the spray tip into one side of your nose. The tip should not reach far into the nose. Rest the side of your index finger against your upper lip. Tip your head back a little and aim the spray toward the back of your nose. See figure E.
10. Press against the other side of your nose with your finger so the nostril is closed. Pump the spray bottle by pushing on the bottom of the bottle with your thumb firmly and quickly for the full dose of medicine. Sniff gently at the same time to help the medicine get to the back of your nose. See figure F. Repeat this step for the other side.
11. Repeat steps 8, 9 and 10 if your healthcare provider tells you to use more than one spray in each nostril.
12. Do not blow your nose for 15 minutes after using the spray.
13. After use, wipe the nozzle on the spray bottle with a clean tissue, and replace the blue cover.
14. Keep the cover and the clip on the spray pump bottle when not in use.
Cleaning the spray pump bottle:
15. To clean the spray pump bottle, remove the blue cover and the spray nozzle only. Soak the cover and spray nozzle in warm water for a few minutes, and then rinse under cold water. See figure G.
16. Shake or tap off the excess water and allow to air dry. Once the cap and spray nozzle are dry, put the nozzle back onto the bottle, and prime the bottle as necessary until a fine mist is made. Use the spray as directed by your healthcare provider.
If the spray bottle does not work:
The hole in the tip of the nozzle may be blocked. Never try to unblock the spray hole or enlarge it with a pin or other sharp object. This will make the spray mechanism not work correctly. Changing the size of the opening can change the amount of medicine you or your child will receive. This could cause an overdose of the medicine. To clean nasal spray pump bottle, refer to Step 15.
Repriming the spray pump is only necessary when it has not been used for more than 2 weeks. To reprime, shake the bottle and only pump the spray bottle one time. Do not reprime if you use the spray more often than every two weeks.
Each Nasacort AQ bottle contains 120 doses of medicine plus a little extra for priming the pump. A check-off chart is included with your Nasacort AQ to help you keep track of the number of sprays. This will help make sure that you receive 120 sprays of Nasacort AQ.
How should I store Nasacort AQ?
- Store Nasacort AQ between 68° to 77°F (20° to 25° C).
- After using 120 sprays, throw the medicine away, as directed by your healthcare provider, even if the bottle is not empty. You may not get enough medicine if you use the bottle after 120 sprays.
Keep Nasacort and all medicines out of the reach of children. General information about the safe and effective use of Nasacort AQ.
