Which Nasal Symptoms Respond Best To Cromolyn Sodium?
The nasal symptoms best helped by cromolyn sodium are watery, runny nose and sneezing. Nasal congestion and postnasal drainage do not respond as well.
Indications for Cromolyn Sodium
The manufacturer’s package insert accompanying a bottle of Nasalcrom lists only one indication: “allergic rhinitis.” Clinical experience shows that its use should be considered in the following conditions:
- Seasonal allergic rhinitis
- Perennial allergic rhinitis
- Occupational allergic rhinitis
- Possibly effective in most forms of non-allergic, non-anatomic rhinitis
It has not been shown to be helpful in treating either vasomotor rhinitis or chemical rhinitis.
What To Expect When Using Cromolyn Sodium
If you have seasonal allergic rhinitis, you should expect a significant reduction or even clearing of your symptoms during your allergy season. Here are some tips for the effective use of Nasalcrom Nasal Solution:
• For best results, cromolyn sodium should be begun two weeks before the pollen season begins, used regularly throughout the season, and not discontinued until the pollen is no longer in the air.
• If you have perennial allergic rhinitis, you should expect a gradual reduction in your symptoms with regular use.
• If you have some other form of rhinitis in which the actions of cromolyn sodium might warrant your giving it a try, look for gradual improvement with prolonged use.
If, like some of my patients, you have an isolated problem, such as an allergy to your brother-in-law’s cat and you experience a flare-up of your nasal symptoms every time you go to his home, you may find that two sprays of cromolyn sodium on each side of the nose about 15 minutes before going into his home, followed by two more sprays on each side of the nose every four hours while there, will offer protection. This doesn’t always work, but it works often enough that it’s worth a try. If you have an allergy to an agent at work to which you are exposed only occasionally, cromolyn sodium could be used in a similar manner to prevent symptoms.
Side Effects Of Cromolyn Sodium
Sneezing is the most common side effect of cromolyn sodium. This is followed by burning and stinging, bad taste in the mouth, nasal bleeding, and increased postnasal drip. A rash is the least common side effect.
Warnings Regarding Cromolyn Sodium Nasal Solution
Like so many products, the safety and efficacy of cromolyn sodium nasal solution has not been established regarding use during pregnancy, lactation, and in children younger than six years.
