How mast cell inhibitors work: These drugs prevent the release of histamine and other chemicals that cause allergic symptoms from mast cells when an individual comes into contact with an allergen like pollen.
Who should not use these medications: Individuals who are allergic to any components of the nasal spray or eye drops should not take mast cell inhibitors.
Use: Frequent dosing is necessary, since the effect only lasts up to 8 hours. Mast cell inhibitors are available as nasal sprays to prevent runny nose or eye drops for itchy eyes.
Drug or food interactions: Since these drugs have little or no effect beyond the area applied, they are unlikely to interact with other drugs.
Side effects:Contact lenses should not be worn if using eye drops. Eye drops may cause stinging, burning, redness, and, possibly, severe swelling of eyes. Nasal congestion, sneezing, itching, nosebleeds, and burning have been reported with use of cromolyn sodium nasal sprays.
