Cromolyn Sodium (Nasalcrom)
(Intal)
prevents release of histamine from
sensitized mast cells.
poorly absorbed, action is local
long term prophylaxis of allergic
disorders, rhinitis, asthma:
prevent exercise induced bronchospasm

Patient / family
teaching
nasal, throat, & trachea irritation;
unpleasant taste
inhalation - inhaler capsule or nebulizer
solution and intranasal spray
assess for respiratory function before,
during, and after therapy;
reduction of dose of other asthma meds
may be possible after 2-4 weeks of
therapy;
pre-treat with bronchodilator to increase
delivery of inhalation (if ordered)
do not use solution if cloudy or contains
precipitate.
Must be used routinely.

Teach proper use of inhaler.
Gargle & rinse mouth after each dose to
decrease dryness and throat irritation.
