How do you manage your allergy symptoms? Sneezing, stuffiness and itchy red eyes are more than a bother. Unfortunately, many of the medicines you might take for relief can have unpleasant side effects. As just one example, decongestant nasal sprays for nasal congestion should be used only for a few days. Otherwise, you could develop rebound congestion and find it difficult to stop using the spray. One reader suggests NasalCrom for your allergies.
Can You Benefit from NasalCrom for Your Allergies?
Q. I suffer from allergies. Steroid sprays ease my symptoms but cause nosebleeds and headaches. I am also concerned about the possibility of cataracts.
I switched to NasalCrom nasal spray. It is awesome. I use it twice a day and it works to control my symptoms without serious side effects.
A. Most people have never heard of NasalCrom for allergy relief. It is not advertised as aggressively as many antihistamines or steroid nasal sprays.
How Does NasalCrom Work?
The active ingredient, cromolyn, stabilizes the mast cells in the nose that react to pollen and other allergens. This pharmaceutical was originally developed from an ancient remedy called bishop’s flower (Ammi visnaga). We are glad it worked so well for you. It does require a spritz in each nostril three to four times a day to prevent allergy symptoms.
How Safe Is It to Use NasalCrom for Your Allergies Long Term?
Some readers, aware of the problems with decongestant nasal sprays, wonder whether long-term use of NasalCrom is safe. Here is one such question.
Q. I have been using NasalCrom for years, usually two times a day in allergy seasons and once per day as a preventative the rest of the time. Is there any harm in taking it every day over a long term?
A. Sadly, scientists rarely do methodical studies of medications to determine their long-term safety. However, cromolyn (the active ingredient in NasalCrom) is considered safe and effective as a long-term maintenance treatment for asthma (Sleep & Breathing, Dec. 2012).

We got a bit nervous when we spotted a study linking it to amyloid beta in the brain. However, the research shows that rather than increasing the likelihood of Alzheimer disease, it appears to reduce the risk in mice designed to develop this condition (Journal of Biological Chemistry, Jan. 23, 2015). A subsequent study in mice found that cromolyn increases the neuroprotective activity of specialized brain cells called microglia (Scientific Reports, Jan. 18, 2018). There’s a big leap from mice to humans, but the results suggest that NasalCrom might not pose a problem in the long term.
Linda found this was a motivation to switch to NasalCrom:
“I am very happy using Nasalcrom. I have completely stopped antihistamines as I realized I had trouble retrieving words after a week of starting them.”
RWW agrees that long-term use of Nasalcrom for your allergies appears safe:
“I have used Nasal Crom for 30 years and have had no side effects so far.”
