(be-kloe-meth′a-sone)

Beconase AQ, Qnasal

Func. class.:
Nasal corticosteroid

ACTION:

Readily crosses cell membranes and binds with high affinity to specific cytoplasmic receptors; inhibition of leukocyte infiltration at the site of inflammation, interference in the function of mediators of inflammatory response, and suppression of humoral immune responses

USES:

To relieve symptoms of seasonal/perennial rhinitis

CONTRAINDICATIONS:

Hypersensitivity

Precautions:
Child <6 yr, untreated fungal infections, glaucoma and/or cataracts, nasal septum ulcers/surgery/trauma

DOSAGE AND ROUTES
Calculator

• Adult/child ≥12 yr:
Nasal 1-2 sprays in each nostril bid (42 mcg/spray); 2 sprays in each nostril every day (80 mcg/actuation)

• Child 6-12 yr:
Nasal 1 spray in each nostril bid

Available forms:
nasal spray 42 mcg/metered spray; nasal aerosol 80 mcg/actuation

Administer

• 
Products are not always interchangeable owing to differences in route of administration and in the amount of active drug released per spray

• 
To avoid the spread of infection, do not use the container for more than one person

• 
Product’s effectiveness depends on regular use

Nasal inhalation (metered-dose aerosol) (Qnasal):

• 
Instruct patient to shake the canister well before administering

• 
Before first use, instruct the patient to prime the pump by actuating 4 times. After the initial priming, the dose-counter should read 120

• 
If the canister is not used for 7 consecutive days, instruct the patient to prime by actuating 2 times

• 
Instruct patient on proper administration technique

Nasal inhalation (pump spray) (Beconase AQ):

• 
Instruct patient to shake the nasal sprayer well before use

• 
Before first use, instruct the patient to prime the pump by actuating 6 times

• 
If the pump is not used for 7 days, prime until a fine spray appears

• 
Instruct patient on proper administration technique

• 
After use, rinse the tip of the bottle with hot water, taking care not to suck water into the bottle, and dry with a clean tissue; replace the cap
