NURSING CONSIDERATIONS
Assess:

• 
Respiratory status: rate, rhythm, increase in bronchial secretions, wheezing, chest tightness; provide fluids to 2 L/day to decrease thickness of secretions; check for oral candidiasis

• 
Bronchospasm:
stop treatment, give bronchodilator

• 
Storage at 59° F-86° F (15° C-30° C); keep away from heat, open flame

Evaluate:

Therapeutic response: absence of asthma, rhinitis

Teach patient/family:

• 
To notify prescriber of pharyngitis, nasal bleeding, oral candidiasis

• 
To use good oral hygiene if using nebulizer or inhaler

• 
To avoid breastfeeding

• 
That burning or stinging may occur with first few doses of inhalation use
