Qnasl (beclocmethasone dipropionate) nasal aerosol is used to treat nasal symptoms associated with seasonal and perennial allergic rhinitis for patients who are 12 years of age or older. Qnasl nasal aerosol is a corticosteroid. Common side effects of Qnasl nasal aerosol include nasal discomfort, nosebleed, and headache.
The recommended dose of Qnasl nasal aerosol is 320 mcg per day divided into 2 nasal aerosol sprays per nostril once a day. There are no known drug interactions for Qnasl nasal aerosol. Tell your doctor all medications you use. Qnasl nasal aerosol should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus. Caution should be exercised when Qnasl nasal aerosol is administered to nursing mothers as some corticosteroids have been detected in human breast milk.
Our Qnasl (beclocmethasone dipropionate) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

- Epistaxis, nasal discomfort, nasal ulcerations, Candida albicans infection, and impaired wound healing [see WARNINGS AND PRECAUTIONS]

- Immunosuppression [see WARNINGS AND PRECAUTIONS]
Clinical Trials Experience
The safety data described below for adults and adolescents 12 years of age and older with seasonal or perennial allergic rhinitis are based on four placebo-controlled clinical trials of 2 to 6 weeks' duration evaluating doses of beclomethasone nasal aerosol from 80 to 320 mcg once daily. These short-term trials included a total of 1394 patients with either seasonal or perennial allergic rhinitis. Of these, 575 (378 female and 197 male) received at least one dose of QNASL Nasal Aerosol, 320 mcg once daily and 578 (360 female and 218 male) received placebo. Patient ages ranged from 12 to 82 years and the racial distribution of patients was 81% white, 16% black, and 4% 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.
Short-Term (2-6 Weeks) Trials
Overall, the incidence of adverse reactions did not differ appreciably between patients treated with QNASL Nasal Aerosol and those who were treated with placebo. Less than 2% of patients in the clinical trials discontinued treatment because of adverse reactions with the rate of withdrawal among patients who received QNASL Nasal Aerosol similar to or lower than the rate among patients who received placebo. Table 1 displays the common adverse reactions ( ≥ 1% and greater than placebo-treated patients).

Duration (Safety Population)
|QNASL Nasal Aerosol 320 mcg
(N = 575)
(N = 578)
|Nasal Discomfort||30 (5.2)||28 (4.8)|
|Epistaxis||11 (1.9)||7 (1.2)|
|Headache||13 (2.3)||9 (1.6)|
Nasal ulcerations occurred in 2 patients treated with placebo and in 1 patient treated with QNASL Nasal Aerosol. There were no differences in the incidence of adverse reactions based on gender or race. Clinical trials did not have sufficient numbers of patients aged 65 years and older to determine whether they respond differently than younger patients.
Long-Term 52-Week Safety Trial
In a 52-week placebo-controlled long term safety trial in patients with PAR, 415 patients (128 males and 287 females, aged 12 to 74 years) were treated with QNASL Nasal Aerosol at a dose of 320 mcg once daily and 111 patients (44 males and 67 females, aged 12 to 67 years) were treated with placebo. Of the 415 patients treated with QNASL Nasal Aerosol, 219 patients were treated for 52 weeks and 196 patients were treated for 30 weeks. While most adverse events were similar in type and rate between the treatment groups, epistaxis occurred more frequently in patients who received QNASL Nasal Aerosol (45 out of 415, 11%) than in patients who received placebo (2 out of 111, 2%). Epistaxis also tended to be more severe in patients treated with QNASL Nasal Aerosol. In 45 reports of epistaxis in patients who received QNASL Nasal Aerosol, 27, 13, and 5 cases were of mild, moderate, and severe intensity, respectively, while the reports of epistaxis in patients who received placebo were of mild (1) and moderate (1) intensity. Seventeen patients treated with QNASL Nasal Aerosol experienced adverse reactions that led to withdrawal from the trial compared to 3 patients treated with placebo. There were 4 nasal erosions and 1 nasal septum ulceration which occurred in patients who received QNASL Nasal Aerosol, and no erosions or ulcerations noted in patients who received placebo. No patient experienced a nasal septum perforation during the trial.
In addition to adverse reactions reported from clinical trials for QNASL Nasal Aerosol, the following adverse events have been reported during use of other intranasal and inhaled formulations of beclomethasone dipropionate. 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 beclomethasone dipropionate or a combination of these factors.
Intranasal beclomethasone dipropionate: Nasal septal perforation, glaucoma, cataracts, loss of taste and smell, and hypersensitivity reactions including anaphylaxis, angioedema, rash, and urticaria have been reported following intranasal administration of beclomethasone dipropionate.
Inhaled beclomethasone dipropionate: Hypersensitivity reactions, including anaphylaxis, angioedema, rash, urticaria, and bronchospasm have been reported following the oral inhalation of beclomethasone dipropionate.
