Cromolyn (EENT) Dosage and Administration
General
-
For patients with seasonal or perennial rhinitis, continue therapy throughout the period of allergen exposure (e.g., until the pollen season is over or contact with allergen has ceased).
-
If exposure to allergens cannot be predicted, initiate therapy at the first sign of nasal symptoms.
-
Should not use other ocular agents with ophthalmic solution unless directed by a clinician. However, may use corticosteroids with ophthalmic solution.
Administration
Administer intranasally or topically to the eye.
Administer at regular intervals.
Intranasal Administration
Parents or care providers must supervise use by young children. In very young children, an adult should administer nasal solution. Use care when inserting the nozzle into the nose to avoid injury.
Prior to administration, clear nasal passages by blowing the nose; administration of a topical nasal decongestant may be necessary. Inhale through the nose during administration.
For maximum therapeutic effect, initiate therapy before (e.g., ≤1–2 weeks before) and continue at regular intervals during the period of allergen exposure.
Ophthalmic Administration
Applied topically to the eye as an ophthalmic solution just inside the lower eyelid; patients should avoid applying the solution directly on the cornea.
To avoid contamination of dropper tip and solution, avoid touching the tip of the dispensing dropper or container to the eye, fingers, or any other surface.
Dosage
Available as cromolyn sodium.
Nasal pump delivers 5.2 mg of cromolyn sodium per metered spray.
One drop of cromolyn sodium ophthalmic solution contains approximately 1.6 mg of cromolyn sodium.
