    Nasalcrom


    Description

    Cromolyn nasal solution is used to help prevent or treat the symptoms (sneezing, wheezing, runny nose, itching) of seasonal (short-term) or chronic (long-term) allergic rhinitis. Cromolyn powder for nasal inhalation is used to help prevent seasonal (short-term) allergic rhinitis.

    This medicine works by acting on certain cells in the body, called mast cells, to prevent them from releasing substances that cause the allergic reaction.

    When cromolyn is used to treat chronic (long-term) allergic rhinitis, an antihistamine and/or a nasal decongestant may be used with this medicine, especially during the first few weeks of treatment.

    Nasal cromolyn is available without a prescription.

    This product is available in the following dosage forms:

    • Spray
