What are the side effects you encounter while taking this medicine? |
Avamys Nasal Spray is a corticosteroid indicated for treatment of symptoms of seasonal and perennial allergic rhinitis in adults and children ≥2 years.
Avamys® (fluticasone furoate) Nasal Spray is indicated for the treatment of the symptoms of seasonal and perennial allergic rhinitis in patients aged 2 years and older.
Administer Avamys Nasal Spray by the intranasal route only. Prime Avamys Nasal Spray before using for the first time by shaking the contents well and releasing 6 sprays into the air away from the face. When Avamys Nasal Spray has not been used for more than 30 days or if the cap has been left off the bottle for 5 days or longer, prime the pump again until a fine mist appears. Shake Avamys Nasal Spray well before each use.
Titrate an individual patient to the minimum effective dosage to reduce the possibility of side effects.
For intranasal use only. Usual starting dosages:
The recommended starting dosage is 110 mcg once daily administered as 2 sprays (27.5 mcg/spray) in each nostril. When the maximum benefit has been achieved and symptoms have been controlled, reducing the dosage to 55 mcg (1 spray in each nostril) once daily may be effective in maintaining control of allergic rhinitis symptoms.
The recommended starting dosage in children is 55 mcg once daily administered as 1 spray (27.5 mcg/spray) in each nostril. Children not adequately responding to 55 mcg may use 110 mcg (2 sprays in each nostril) once daily. Once symptoms have been controlled, dosage reduction to 55 mcg once daily is recommended.
Avamys Nasal Spray is a nasal spray suspension. Each spray (50 microliters) delivers 27.5 mcg of Avamys.
Nasal spray: 27.5 mcg of Avamys in each 50-microliter spray. (3)
Supplied in 10-g bottle containing 120 sprays. (16)
Avamys Nasal Spray is contraindicated in patients with hypersensitivity to any of its ingredients .
Hypersensitivity to ingredients. (4)
Epistaxis and Nasal Ulceration
In clinical trials of 2 to 52 weeks’ duration, epistaxis and nasal ulcerations were observed more frequently and some epistaxis events were more severe in patients treated with Avamys Nasal Spray than those who received placebo .
Candida Infection
Evidence of localized infections of the nose with Candida albicans was seen on nasal exams in 7 of 2,745 patients treated with Avamys Nasal Spray during clinical trials and was reported as an adverse event in 3 patients. When such an infection develops, it may require treatment with appropriate local therapy and discontinuation of Avamys Nasal Spray. Therefore, patients using Avamys 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
Postmarketing cases of nasal septal perforation have been reported in patients following the intranasal application of Avamys Nasal Spray .
Impaired Wound Healing
Because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal ulcers, nasal surgery, or nasal trauma should not use Avamys Nasal Spray until healing has occurred.
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.
Glaucoma and cataract formation was evaluated with intraocular pressure measurements and slit lamp examinations in 1 controlled 12-month trial in 806 adolescent and adult patients aged 12 years and older and in 1 controlled 12-week trial in 558 children aged 2 to 11 years. The patients had perennial allergic rhinitis and were treated with either Avamys Nasal Spray (110 mcg once daily in adult and adolescent patients and 55 or 110 mcg once daily in pediatric patients) or placebo. Intraocular pressure remained within the normal range (less than 21 mmHg) in greater than or equal to 98% of the patients in any treatment group in both trials. However, in the 12-month trial in adolescents and adults, 12 patients, all treated with Avamys Nasal Spray 110 mcg once daily, had intraocular pressure measurements that increased above normal levels (greater than or equal to 21 mmHg). In the same trial, 7 patients (6 treated with Avamys Nasal Spray 110 mcg once daily and 1 patient treated with placebo) had cataracts identified during the trial that were not present at baseline.
Hypersensitivity reactions, including anaphylaxis, angioedema, rash, and urticaria, may occur after administration of Avamys Nasal Spray. Discontinue Avamys Nasal Spray if such reactions occur .
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 a patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin may be indicated. If a patient is exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. If chickenpox or measles develops, treatment with antiviral agents may be considered.
Corticosteroids should be used with caution, if at all, in patients with active or quiescent tuberculous 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.
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 Avamys 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, 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.
Coadministration with ritonavir is not recommended because of the risk of systemic effects secondary to increased exposure to Avamys. Use caution with the coadministration of Avamys Nasal Spray and other potent cytochrome P450 3A4 inhibitors, such as ketoconazole .
Corticosteroids may cause a reduction in growth velocity when administered to pediatric patients. Monitor the growth routinely of pediatric patients receiving Avamys Nasal Spray. To minimize the systemic effects of intranasal corticosteroids, including Avamys Nasal Spray, titrate each patient’s dose to the lowest dosage that effectively controls his/her symptoms .
Systemic and local corticosteroid use may result in the following:
The most common adverse reactions (>1% incidence) included headache, epistaxis, pharyngolaryngeal pain, nasal ulceration, back pain, pyrexia, and cough. (6.1)

The safety data described below reflect exposure to Avamys Nasal Spray in 1,563 patients with seasonal or perennial allergic rhinitis in 9 controlled clinical trials of 2 to 12 weeks’ duration. The data from adults and adolescents are based upon 6 clinical trials in which 768 patients with seasonal or perennial allergic rhinitis (473 females and 295 males aged 12 years and older) were treated with Avamys Nasal Spray 110 mcg once daily for 2 to 6 weeks. The racial distribution of adult and adolescent patients receiving Avamys Nasal Spray was 82% white, 5% black, and 13% other. The data from pediatric patients are based upon 3 clinical trials in which 795 children with seasonal or perennial rhinitis (352 females and 443 males aged 2 to 11 years) were treated with Avamys Nasal Spray 55 or 110 mcg once daily for 2 to 12 weeks. The racial distribution of pediatric patients receiving Avamys Nasal Spray was 75% white, 11% black, and 14% other.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adults and Adolescents Aged 12 Years and Older
Overall adverse reactions were reported with approximately the same frequency by patients treated with Avamys Nasal Spray and those receiving placebo. Less than 3% of patients in clinical trials discontinued treatment because of adverse reactions. The rate of withdrawal among patients receiving Avamys Nasal Spray was similar to or lower than the rate among patients receiving placebo.
Table 1 displays the common adverse reactions (greater than 1% in any patient group receiving Avamys Nasal Spray) that occurred more frequently in patients aged 12 years and older treated with Avamys Nasal Spray compared with placebo-treated patients.
Adverse Event | Adult and Adolescent Patients Aged 12 Years and Older | |
Vehicle Placebo (n = 774) | Avamys Nasal Spray 110 mcg Once Daily (n = 768) | |
Headache | 54 (7%) | 72 (9%) |
Epistaxis | 32 (4%) | 45 (6%) |
Pharyngolaryngeal pain | 8 (1%) | 15 (2%) |
Nasal ulceration | 3 (<1%) | 11 (1%) |
Back pain | 7 (<1%) | 9 (1%) |
There were no differences in the incidence of adverse reactions based on gender or race. Clinical trials did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently from younger subjects.
Pediatric Patients Aged 2 to 11 Years
In the 3 clinical trials in pediatric patients aged 2 to younger than 12 years, overall adverse reactions were reported with approximately the same frequency by patients treated with Avamys Nasal Spray and those receiving placebo. Table 2 displays the common adverse reactions (greater than 3% in any patient group receiving Avamys Nasal Spray) that occurred more frequently in patients aged 2 to 11 years treated with Avamys Nasal Spray compared with placebo-treated patients.
Adverse Event | Pediatric Patients Aged 2 to Younger than 12 Years | ||
Vehicle Placebo (n = 429) | Avamys Nasal Spray 55 mcg Once Daily (n = 369) | Avamys Nasal Spray 110 mcg Once Daily (n = 426) | |
Headache | 31 (7%) | 28 (8%) | 33 (8%) |
Nasopharyngitis | 21 (5%) | 20 (5%) | 21 (5%) |
Epistaxis | 19 (4%) | 17 (5%) | 17 (4%) |
Pyrexia | 7 (2%) | 17 (5%) | 19 (4%) |
Pharyngolaryngeal pain | 14 (3%) | 16 (4%) | 12 (3%) |
Cough | 12 (3%) | 12 (3%) | 16 (4%) |
There were no differences in the incidence of adverse reactions based on gender or race. Pyrexia occurred more frequently in children aged 2 to younger than 6 years compared with children aged 6 to younger than 12 years.
Long-term (52-Week) Safety Trial
In a 52-week, placebo-controlled, long-term safety trial, 605 patients (307 females and 298 males aged 12 years and older) with perennial allergic rhinitis were treated with Avamys Nasal Spray 110 mcg once daily for 12 months and 201 were treated with placebo nasal spray. While most adverse reactions were similar in type and rate between the treatment groups, epistaxis occurred more frequently in patients who received Avamys Nasal Spray (123/605, 20%) than in patients who received placebo (17/201, 8%). Epistaxis tended to be more severe in patients treated with Avamys Nasal Spray. All 17 reports of epistaxis that occurred in patients who received placebo were of mild intensity, while 83, 39, and 1 of the total 123 epistaxis events in patients treated with Avamys Nasal Spray were of mild, moderate, and severe intensity, respectively. No patient experienced a nasal septal perforation during this trial.
In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during postmarketing use of Avamys 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. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, or causal connection to Avamys or a combination of these factors.
Immune System Disorders
Hypersensitivity reactions, including anaphylaxis, angioedema, rash, and urticaria.
Respiratory, Thoracic, and Mediastinal Disorders
Rhinalgia, nasal discomfort (including nasal burning, nasal irritation, and nasal soreness), nasal dryness, and nasal septal perforation.
Avamys is cleared by extensive first-pass metabolism mediated by CYP3A4. In a drug interaction trial of intranasal Avamys and the CYP3A4 inhibitor ketoconazole given as a 200-mg once-daily dose for 7 days, 6 of 20 subjects receiving Avamys and ketoconazole had measurable but low levels of Avamys compared with 1 of 20 receiving Avamys and placebo. Based on this trial and the low systemic exposure, there was a 5% reduction in 24-hour serum cortisol levels with ketoconazole compared with placebo. The data from this trial should be carefully interpreted because the trial was conducted with ketoconazole 200 mg once daily rather than 400 mg, which is the maximum recommended dosage. Therefore, caution is required with the coadministration of Avamys Nasal Spray and ketoconazole or other potent CYP3A4 inhibitors.
Based on data with another glucocorticoid, fluticasone propionate, metabolized by CYP3A4, coadministration of Avamys Nasal Spray with the potent CYP3A4 inhibitor ritonavir is not recommended because of the risk of systemic effects secondary to increased exposure to Avamys. High exposure to corticosteroids increases the potential for systemic side effects, such as cortisol suppression.
Enzyme induction and inhibition data suggest that Avamys is unlikely to significantly alter the cytochrome P450-mediated metabolism of other compounds at clinically relevant intranasal dosages.
Potent inhibitors of cytochrome P450 3A4 (CYP3A4) may increase exposure to Avamys.
Hepatic impairment may increase exposure to Avamys. Use with caution in patients with moderate or severe hepatic impairment.
Teratogenic Effects
Pregnancy Category C. Corticosteroids have been shown to be teratogenic in laboratory animals when administered systemically at relatively low dosage levels.
There were no teratogenic effects in rats and rabbits at inhaled Avamys dosages of up to 91 and 8 mcg/kg/day, respectively (approximately 7 and 1 times, respectively, the maximum recommended daily intranasal dose in adults on a mcg/m2 basis). There was also no effect on pre- or post-natal development in rats treated with up to 27 mcg/kg/day by inhalation during gestation and lactation (approximately 2 times the maximum recommended daily intranasal dose in adults on a mcg/m2 basis).
There are no adequate and well-controlled studies in pregnant women. Avamys Nasal Spray should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Nonteratogenic Effects
Hypoadrenalism may occur in infants born of mothers receiving corticosteroids during pregnancy. Such infants should be carefully monitored.
It is not known whether Avamys is excreted in human breast milk. However, other corticosteroids have been detected in human milk. Since there are no data from controlled trials on the use of intranasal Avamys by nursing mothers, caution should be exercised when Avamys Nasal Spray is administered to a nursing woman.
Controlled clinical trials with Avamys Nasal Spray included 1,224 patients aged 2 to 11 years and 344 adolescent patients aged 12 to 17 years . The safety and effectiveness of Avamys Nasal Spray in children younger than 2 years have not been established.
Controlled clinical trials 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 “catch-up” growth following discontinuation of treatment with intranasal corticosteroids has not been adequately studied. The growth of pediatric patients receiving intranasal corticosteroids, including Avamys 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 Avamys Nasal Spray, each patient’s dose should be titrated to the lowest dosage that effectively controls his/her symptoms.
A randomized, double-blind, parallel-group, multicenter, 1-year placebo-controlled clinical growth trial evaluated the effect of 110 mcg of Avamys Nasal Spray once daily on growth velocity in 474 prepubescent children (girls aged 5 to 7.5 years and boys aged 5 to 8.5 years) with stadiometry. Mean growth velocity over the 52-week treatment period was lower in the patients receiving Avamys Nasal Spray (5.19 cm/year compared with placebo (5.46 cm/year). The mean treatment difference was -0.27 cm/year (95% CI: -0.48 to -0.06) .
Clinical studies of Avamys Nasal Spray did not include sufficient numbers of subjects aged 65 years and older 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.
Use Avamys Nasal Spray with caution in patients with moderate or severe hepatic impairment .
No dosage adjustment is required in patients with renal impairment .
Chronic overdosage may result in signs/symptoms of hypercorticism . There are no data on the effects of acute or chronic overdosage with Avamys Nasal Spray. Because of low systemic bioavailability and an absence of acute drug-related systemic findings in clinical trials (with dosages of up to 440 mcg/day for 2 weeks [4 times the maximum recommended daily dose]), overdose is unlikely to require any therapy other than observation.
Intranasal administration of up to 2,640 mcg/day (24 times the recommended adult dose) of Avamys was administered to healthy human volunteers for 3 days. Single- and repeat-dose trials with orally inhaled Avamys doses of 50 to 4,000 mcg have shown decreased mean serum cortisol at doses of 500 mcg or higher. The oral median lethal dose in mice and rats was greater than 2,000 mg/kg (approximately 74,000 and 147,000 times, respectively, the maximum recommended daily intranasal dose in adults and 52,000 and 105,000 times, respectively, the maximum recommended daily intranasal dose in children, on a mcg/m2 basis).
Acute overdosage with the intranasal dosage form is unlikely since 1 bottle of Avamys Nasal Spray contains approximately 3 mg of Avamys, and the bioavailability of Avamys is less than 1% for 2.64 mg/day given intranasally and 1% for 2 mg/day given as an oral solution.
Avamys, the active component of Avamys Nasal Spray, is a synthetic fluorinated corticosteroid having the chemical name (6α,11β,16α,17α)-6,9-difluoro-17-{[(fluoro-methyl)thio]carbonyl}-11-hydroxy-16-methyl-3-oxoandrosta-1,4-dien-17-yl 2-furancarboxylate and the following chemical structure:
How to use your Avamys Nasal Spray
Follow the instructions below. If you have any questions, ask your healthcare provider or pharmacist.
Before taking a dose of Avamys Nasal Spray, gently blow your nose to clear your nostrils. Shake the bottle well. Then do these 3 simple steps: Place, Press, Repeat.
1. PLACE
Tilt your head forward a little bit. Hold the device upright. PLACE the nozzle in one of your nostrils (Figure 4).
Point the end of the nozzle toward the side of your nose, away from the center of your nose (septum). This helps get the medicine to the right part of your nose.
2. PRESS
PRESS the button all the way in 1 time to spray the medicine in your nose while you are breathing in (Figure 5).
Do not get any spray in your eyes. If you do, rinse your eyes well with water.
Take the nozzle out of your nose. Breathe out through your mouth (Figure 6).
3. REPEAT
To deliver the medicine to the other nostril, REPEAT Steps 1 and 2 in the other nostril (Figure 7).
If your healthcare provider has told you to take 2 sprays in each nostril, do Steps 1-3 again.
Put the cap back on the device after you have finished taking your dose.
How to clean your Avamys Nasal Spray
After each use: wipe the nozzle with a clean, dry tissue (Figure 8). Never try to clean the nozzle with a pin or anything sharp because this will damage the nozzle. Do not use water to clean the nozzle.
Once a week: clean the inside of the cap with a clean, dry tissue (Figure 9). This will help keep the nozzle from getting blocked.
