FULL PRESCRIBING INFORMATION
1. INDICATIONS
AND USAGE
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.
2. DOSAGE
AND ADMINISTRATION
Administer NASACORT AQ Nasal Spray by the intranasal route only. Shake NASACORT AQ Nasal
Spray well before each use.
2.1 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.
2.2 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.
Children 2 to 5 years of age: The recommended and maximum dose is 110 mcg
per day given as one spray in each nostril once daily.
NASACORT AQ Nasal Spray is not recommended for children under 2 years of age.
2.3 Administration
Information
Priming: 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 (5),
Patient Counseling Information (17), and Adverse Reactions (6)]
BACK TO TOP
3. DOSAGE
FORMS AND STRENGTHS
NASACORT AQ Nasal Spray is a metered-dose pump spray containing the active
ingredient triamcinolone acetonide. Each actuation delivers 55 mcg triamcinolone
acetonide from the nasal actuator after an initial priming of 5 sprays. Each
16.5 gram bottle (120 actuations) contains 9.075 mg of triamcinolone acetonide.
The bottle should be discarded when the labeled-number of actuations have been
reached even though the bottle is not completely empty.
BACK TO TOP
4. CONTRAINDICATIONS
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.
BACK TO TOP
5 WARNINGS AND PRECAUTIONS
5.1 Local Nasal Effects
Epistaxis: In clinical studies of 2 to 12 weeks duration, epistaxis was observed more
frequently in patients treated with NASACORT AQ Nasal Spray than those who received
placebo [see Adverse Reactions (6)].
Nasal Septal Perforation: In clinical trials, nasal septum perforation was reported
in one adult patient treated with NASACORT AQ Nasal Spray.
Candida Infection: 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.
5.2 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.
5.3 Immunosuppression
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.
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 hypercoticism 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.
5.5 Effect on Growth
Corticosteroids 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 (8.4)].

6.1 Clinical
Trials Experience
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.

6.2 Post-Marketing
Experience
In addition to the adverse drug reactions reported during clinical studies and listed above,
the following adverse events have been identified during post-approval use of NASACORT AQ
Nasal Spray. Because these events 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. Events 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.
BACK TO TOP
8. USE
IN SPECIFIC POPULATIONS
8.1 Pregnancy
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.
8.3 Nursing
Mothers
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.
8.4 Pediatric Use
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 (14)].
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 of final adult height are unknown. The potential for “catch-up” 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 prolonged 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 potential for NASACORT AQ Nasal Spray to cause growth suppression in susceptible
patients and when given at higher than recommended dosages cannot be ruled out.
8.5 Geriatric Use
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.
BACK TO TOP
10. OVERDOSAGE
Chronic overdosage may result in signs/symptoms of hypercorticism [see Warnings and
Precautions (5.4)]. 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.
BACK TO TOP
11. DESCRIPTION
Triamcinolone acetonide, USP, the active ingredient in NASACORT AQ Nasal Spray, is a
corticosteroid with a molecular weight of 434.51 and with the chemical designation
9-Fluoro-11ß,16 ,17,21-tetrahydroxypregna-1,4-diene-3,20-dione cyclic
16,17-acetal with acetone (C24H31FO6).
NASACORT AQ Nasal Spray is a thixotropic,
water-based metered-dose pump spray formulation unit containing a microcrystalline suspension
of triamcinolone acetonide in an aqueous medium. Microcrystalline cellulose, carboxymethylcellulose
sodium, polysorbate 80, dextrose, benzalkonium chloride, and edetate disodium are contained in this
aqueous medium; hydrochloric acid or sodium hydroxide may be added to adjust the pH to a target of
5.0 within a range of 4.5 and 6.0.
BACK TO TOP
12. CLINICAL PHARMACOLOGY
12.1 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.
12.2 Pharmacodynamics
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.
Adrenal Function: In order to evaluate the effects of systemic absorption on
the Hypothalamic-Pituitary-Adrenal (HPA) axis, 3 clinical studies, one each in adults
and in children 6-12 years of age and 2-5 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, HPA axis assessment was
performed; however, the results were inconclusive and an effect of
NASACORT AQ Nasal Spray on adrenal function in children 2 to
5 years of age cannot be ruled out.
12.3 Pharmacokinetics
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 6ß-hydroxytriamcinolone
acetonide, 21-carboxytriamcinolone acetonide and 21-carboxy-6ß-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.

13. NONCLINICAL
TOXICOLOGY
13.1 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.
13.2 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.

14. CLINICAL
STUDIES
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 AQ 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).

Patient Instructions for Use
Read these instructions carefully before using your Nasacort AQ.
Before using the spray pump bottle:
| 1. |
Pull the blue cover and the clip off
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. |
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.
Important information
Repriming the spray pump is only necessary when it has not been used for more than 2 vweeks.
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. |
