NasalCrom (Cromolyn Sodium) Is Surprisingly Helpful for Allergies

Are you sneezing, sniffling and congested? Are allergies making you miserable? Antihistamines and corticosteroids are popular. NasalCrom is another option!
Cc0 from

You’ve probably never heard of NasalCrom nasal spray for allergies. It doesn’t get the kind of attention that many other allergy treatments receive.

There are commercials for antihistamines like Claritin (loratadine) Xyzal (levocetirizine) or Zyrtec (cetirizine). There are also corticosteroid nasal sprays such as Flonase (fluticasone), Nasacort (triamcinolone) and Nasonex (mometasone). The commercials make it seem as if such products are the ideal solution to solving allergy symptoms.

They may have their place, but we really like NasalCrom because it is neither an antihistamine nor a steroid. To quote the famous Apple computer ad from decades ago: “Think Different.”

Q. I read in a health newsletter a few years ago that OTC NasalCrom would help allergies. My husband suffered with runny nose and nasal congestion for years.

After using NasalCrom, his allergy totally disappeared. I didn’t have to iron many handkerchiefs after that, so I was delighted!

A. NasalCrom is different from all other allergy medications. It contains cromolyn, which stabilizes the mast cells in the nose responsible for many, if not most, allergy symptoms.

Mast Cells Cause a LOT of Mischief:

Mast cells are found in your eyes, nose and lungs (and other places in your body) that are highly sensitive to allergens.

Think of mast cells as floating mines. When they come into contact with allergens like ragweed pollen or dust mite poop, a switch gets thrown on these cellular “mines” and all hell breaks loose.

Mast cells start releasing histamine and other chemicals called kinins (pronounced KYE-nins), which then turn on a cascade of other nasty things like leukotrienes and prostaglandins. The end result is sneezing, itching, inflammation, and congestion.

Stabilizing Mast Cells:

If you can stabilize mast cells and make them less sensitive to allergens they appear to be less likely to trigger the release of all those nasty chemicals described above. That way you can prevent symptoms at the source of the problem.

We think such an approach may be more logical than trying to block the effect of histamine with antihistamines. And we think it is safer that squirting steroids in your nose on a regular basis. Some of the corticosteroid is absorbed into your body.

Shutting the Barn Door BEFORE the Horses get Out:

Think of it this way. If your mast cells are like a barn holding in a bunch of wild horses (histamine molecules), then what would be more efficient–reinforcing the door and walls of the barn to keep those wild histamines inside or trying to protect all the grass in your pasture from having those histamine “horses” nibbling away at it? Antihistamines are like a chemical barrier that trys to protect your grass once the horses are out of the barn. But they are not 100 percent efficient, and some histamine will always find a target and wreak havoc. Keeping the barn closed tightly (or the mast cells stabilized) seems to us to be a more effective approach.

Nasalcrom to the Rescue:

Cromolyn (NasalCrom) was first introduced as a prescription product in 1983. NasalCrom went over the counter in 1997. Cromolyn, the active ingredient in NasalCrom, was originally derived from an herb, the fruit of bishop’s weed (Ammi visnaga), which was traditionally used to treat asthma.

The compound cromolyn stabilizes highly sensitive mast cells in the lining of the nose and lungs so they can better resist the onslaught of pollen. It won’t cause drowsiness or cognitive impairment and, if used regularly, it is quite effective. It can be taken for up to twelve weeks. Unlike decongestant nose sprays, there is no need to fear developing dependency.

Side Effects:

Cromolyn is very safe and does not cause drowsiness or rebound nasal congestion the way OTC nasal decongestants can. Some people may experience temporary sneezing, nasal burning, or a bad taste in their mouth.


You must use NasalCrom at least four times a day to really benefit. Some experts believe it is less effective than intranasal corticosteroids. We suggest that it is safer and worth a try if you are the kind of person who can spritz your nostrils three to four times daily on a regular basis.

    I started using NasalCrom in the 80’s for severe hay fever as a teenager. It was a miracle drug for me. I used it for about 10 years, and then suddenly I no longer suffered from hay fever. I had run out of it and didn’t take it for a few days instead of buying more and realized I didn’t need it. I have not had any hay fever since. I did have allergy to cats, and if I was cleaning a dusty area I would have symptoms but both were manageable by just getting away from the source.

    Unfortunately I just got a new Shih Tzu puppy, and within 24 hours it was obvious I am allergic to him. I have a black lab I have had for 4 years with no allergies. I have had several dogs in my life, and no allergies to any of them so this was a shock. I went out and tracked down a bottle of NasalCrom, and I am hoping it will work like before and let me keep this puppy. Otherwise I am gonna devastate my son cause it’s his puppy to raise.

    I got Zyrtec to take also. Just really hoping this works. One dose of NasalCrom, and I felt a lot better for an hour then symptoms came back. I am hoping after multiple doses I will be able to keep this puppy and not have to break my son’s heart.

    I also wanted to say I had told people NasalCrom cured my hay fever, and no one ever believed me. I see here that others said it did the same for their allergies here, and they were able to stop taking it. It’s an interesting phenomenon but there is no other explanation for why mine disappeared and I have had no trouble for 20 years. I had severe hay fever for many years and it just stopped. Fingers crossed it will do the same with this puppy or at least reduce symptoms enough that I can tolerate it.

    Thank you for shedding some light on this product. Ive used it for years and it has truly been miraculous for me. I suffered for years with allergies and probably tried every medication out there. They all had serious side effects or lost potency quickly or both.
    I’ve been puzzled as to why so little is known about it and why it is so hard to obtain. My guess is there’s not enough money to be made with this product since it works so well and even seems to permanently diminish allergies over time. Big pharma would love to see this medication disappear.

    I have used this product for 20 years and found it highly effective with no side effects. It was suggested to me by an allergist.

    I Live in a major metro area and no one stocks it – even the stores listed on Nasalcrom’s website don’t have it. Then I was curious who makes it – the only name I can find is Prestige Brands – a conglomerate that owns everything from Spic and Span to Dramamine. So who knows where it is made – and the efficacy of the manufacture and use of this product.
    If it is so good, why aren’t physicians and pharmacists recommending it? Is cromoglicic acid with sodium so alien in the medical community that folks don’t know about it? One pharmacist drew blank stares when I told her it is Cromolyn Sodium which addesses mast cells production of histamine – is this stuff really legit?

    It is a great product. I have been using it since my Dr prescribed it over 30 years ago when a prescription was required. I can no longer find it in retail stores and get it online.

    Where can I buy Nasal Crom?

    NasalCrom is wonderful and really works! Is that why it has been discontinued? Because it is non-habit forming and the pharmaceuticals want you hooked on the others???

    NasalCrom actually works BETTER for me than the allergy pills that cause side effects. I’ve been telling everyone about it for several years. It gets a lot of word-of-mouth recommendations, and I think that’s why we don’t see a huge advertising budget for it. There is nothing to lose as it doesn’t have any dangerous side effects. Just be sure to give it a full week before making a final decision, as it takes several days to “kick in” but then it is WONDERFUL. Rather than addressing symptoms you already have, it prevents you from having the symptoms in the first place. So it feels like I am now back to being a person who just doesn’t have allergies!

    I agree; NasalCrom is much more effective and fast-acting than many of the oral medications I’ve tried. I live in Kentucky and have severe grass and tree allergies that turn me into a sneezy, weepy, red-eyed disaster each spring; however, NasalCrom has done wonders for me. I’ve used it for more than 10 years and have had no issues with it at all. I only use it when pollen levels are forecast to be high or when I’m going to be exposed to specific allergens- I can usually spray a few minutes before mowing the lawn and have absolutely no issues; my husband, who is allergic to cats only uses NasalCrom when he is going to be in close proximity of them, and after he sprays each nostril, he is symptom-free (as long as he doesn’t rub his eyes after petting a cat) for a good 2-3 hours. It has been a game changer for us!

    Your article is so refreshing because NasalCrom is one of the medical profession’s best kept secret, here’s my story
    In 2000 I had my worst ever persistent headache, I was sure I head a tumor, so after a co-worker died from a brain tumor I was convinced that I had one also. I went to see Rob, my then PCP and said, “Rob, I have a brain tumor!!!” I described my headache, which more severe in the back of my head, and mild in the sinus areas. Rob examined my nose, my ears listened to my chest and gave me a prescription for NasalCrom, it wasn’t sold over-the-counter back then. What I like about this doctor had always been his right on conservative treatment of disease processes. But my immediate response was, “ Rob, the pain is in the back of my head!” He responded, “ your ears are very congested”. I was already familiar with Cromolyn Sodium because a pediatric allergist, co-worker, had prescribed the inhaler when I was diagnosed with asthma in the mid 1970s. With a big question mark on my face I took the prescription, filled it, and use it and “voila”, brain tumor gone, no more headache, no more severe itchy eyes( I had deep black circles and rough looking eyelids from constant rubbing and scratching) no more rough black skin. I have used religiously since and recommend to everyone I meet who is experiencing the discomforts of allergy symptoms. I just tell them I would be just as uncomfortable without NasalCrom, show them the bottle, it is always in my purse, discuss the price and tell them it’s worth it. Those that use it love it just as much as I do. Thank you for the opportunity to share this.
    With gratitude,

    Should have been using this product. Instead, my doctor told me to use Flonase or Nasacort. Bad advice because I developed cataracts soon after and now am developing glaucoma. This side effect is in fine print. Optometrist said steroid nasal sprays should only be used for a very short time.

    Nasalcrom has been a lifesaver for me. Thank you for the article. I trust your opinions. I decided to give it a try and my allergies are under control for the first time in YEARS!!!

    excellent in controlling my allergy and cold symptons

    I used NasalCrom for several years at the first sign of my “spring allergies” kicking up. Eventually I got to the point where I was no longer allergic! I believe that preventing allergic reactions helped my body stop producing the IgE that made me prone to those reactions. It’s been over 15 years now and I have not starting reacting again.

    However, I have developed an allergy to flea bites. I may go back on it and see what happens . . .

    I have used Nasalcrom for over 15 years, and most of my allergy symptoms were gone, and I have suffered my whole life with a constant stuffy nose. When I couldn’t find it this past spring and summer anywhere I felt desperate and tried some of those other nasal sprays which didn’t work. On a fluke I searched online, and, “Praise God,” found it there. I now have it auto-delivered about every 5-6 weeks. The first few months I had to use at least 4 times a day but after awhile only morning and night. I really don’t know what I’ll do if I can’t ever find it aagain!

    Please let me know if anyone knows of a source for Intal spincap Inhalers (which are cromolyn based). It is inhaled through a Spinhaler.

    Alternatively, if anyone knows of any kind of cromolyn sodium that would be useful for people with asthma, please forward information to me. Intal was a great product and should NEVER have been removed from the market! I need to get off steroid inhalers. Please help!

    I have used most all the nasal sprays over the years, and because of these I have no sense of smell. I would like to try Nasalcrom but cannot find it anywhere. Tried all the pharmacies and health food stores. Can someone please help me find it??

    I just bought some at Rite-Aid.

    Amazing product!

    I bought mine from Amazon.

    Grace, I love Nasalcrom; it works far better for me that any of the alternatives. Sadly, I never see it in stores, so I just buy it from Amazon. The manufacturer doesn’t seem to advertise this product, but I’m glad it’s still made. Hope they keep making it. Good luck!

    Grace, the official NasalCrom website has a “where to buy” page. That’s how I found it in a local store. Make sure you search for the .44oz AND .88oz — these are often found at different stores.

    Here in eastern Washington I have bought Nasalcrom at Rite Aid.

    Paul, WA

    My allergies had always been horrible until I started using Nasalcrom in the early 1980s. Since then, I have had little-to-no problems and NO side effects. The only problem is that recently Walgreens has stopped carrying it and I’ve had to order it online.

    I just started Nasalcrom two weeks ago because my nebulizer Cromolyn Sodium was discontinued. I’m unable to take steroids and my doctor said I could order it from Canada and the price is prohibitive so I decided to use Nasalcrom since my doctor is out of ideas. I like it so far and I’ve had no asthma attacks but I still get a bit of an allergy cough. I really think it’s a wonderful product.

    After reading the comments regarding Nasalcrom, I decided to give it a try. Although congestion is not an issue for me, I suffer from inflammation, itching, watery eyes, and a bitter, sometimes burning sensation on my tongue. Mast cell inhabition was an appealing approach to my battle to control inflammation and allergic responses.

    However, after doing additional research, I learned one of its ingredients, benzalkonium chloride, is extremely toxic; therefore have discontinued its use. As a result, I question the support of the product by People’s Pharmacy. Can anyone shed additional light on this information?


    Many chemicals can be toxic at high levels and perfectly safe (and even necessary for good health ) at low levels. Iodine is a good example.

    Many anti-bacterial soaps and lotions have contained benzalkonium chloride at levels of up to 5%. At those levels, I can understand why it would be toxic. From my research, however, I have found the following ingredients in Nasalcrom: Each milliliter of Nasalcrom Nasal Solution contains 40 mg cromolyn sodium in purified water with 0.01% benzalkonium chloride to preserve and 0.01% EDTA…

    An Abstract published at (National Institutes of Health) provides the following information (I encourage you to read this carefully):

    Safety review of benzalkonium chloride used as a preservative in intranasal solutions: an overview of conflicting data and opinions.

    Marple B1, Roland P, Benninger M.



    For most multiuse aqueous nasal, ophthalmic, and otic products, benzalkonium chloride (BKC) is the preservative of choice. The American College of Toxicology has concluded that BKC can be safely used as an antimicrobial agent at concentrations up to 0.1%. [NOTE THAT NASALCROM has a concentration of .01%, which is 100 times less.] BKC has been in clinical use since 1935 and is contained in a wide variety of prescription and over-the-counter products. However, over the past several years there have been conflicting reports of damage to human nasal epithelia and/or exacerbation of rhinitis medicamentosa associated with intranasal products containing BKC.


    We sought to review the published literature and determine whether there is sufficient, clinically significant data that would confirm that intranasal products containing BKC are likely to damage human nasal epithelia or exacerbate rhinitis medicamentosa.


    A literature search was conducted for in vivo and in vitro studies that evaluated the effects of BKC on human nasal epithelia.


    A total of 18 studies (14 in vivo, 4 in vitro) were identified that evaluated short- and long-term exposure of concentrations of BKC in concentrations ranging from 0.00045% to 0.1%. Eight studies, including a 6-month and 1-year long-term treatment study, demonstrated no toxic effects associated with BKC, indicating that BKC was neither harmful to nasal tissue nor prone to exacerbate rhinitis medicamentosa. Furthermore, of the 10 studies that concluded that BKC resulted in degenerative changes in human nasal epithelia (eg, ciliary beat frequency, ciliary morphology, mucociliary clearance, epithelial thinning and/or destruction) or that BKC exacerbates rhinitis medicamentosa, only 2 (it was 2 according to the Results section) of these studies were supported by statistically significant differences between BKC and placebo or active control groups were compared. It is important to note that in both of these studies, the protocol incorporated the use or oxymetazoline in some or all of the subjects. Oxymetazoline is associated with rhinitis medicamentosa.


    Intranasal products containing the preservative BKC appear to be safe and well tolerated for both long- and short-term clinical use.

    Paul’s comments continued: Of course, if the use of Nasalcrom causes excessive stinging and/or irritation for you, stop using it. I have used Nasalcrom for about 25 years and it has been the safest and most effective drug I have ever used. I had the worst sinus allergies imaginable and after using Nasalcrom for several years, I started using it less, and less, and less and finally, I went several years without using it at all. It literally cured my allergies. When I finally started mildly suffering from allergies again in the early spring, I resumed my use (only about twice a day for about six to eight weeks) and I was once again allergy free. I am about to start using it again twice a day as spring is near and I am beginning to see flower buds appearing on some trees.

    I really like using Nasalcrom and have used it since it came out, but every pharmacy/pharmacy department I’ve been to no longer carries it, so I ended up ordering it online.

    is it advisable to add Chromolyn to a fluticasone nasalspray regimen

    Back when people smoked tobacco indoors, I used cromolyn sodium all the time (lifetime tobacco allergy). Very effective stuff.

    Where can I purchase NasalCrom?
    Thank you

    I live in South Africa and have a problem with sneezes that go on and on. Closest product I can find is called Stop-Allergy eye drops containing sodium cromoglycate. I decided to use it sprayed up my nose in a fine mist and used when the first sneeze starts it stops me sneezing further. Thanks for a useful bit of advice.

    I buy Veriditas essential oils and have found that using peppermint in boiling water helps clear congestion instantly! I also put it on my clothes to where I can smell it when I go out and it also helps.

    I have been using NasalCrom since the mid 1980s. Before that I had severe allergies that shots could not help. I had allergies year round with many sensitivities.

    After starting NasalCrom…no more shots or antihistamines. I have been virtually allergy-free unless I stop using Nasalcrom. Even then I am much better.

    Really? I am suffering and suffering with allergies! Do you use this with another spray or just this spray? I am using Flonase along with Allegra. I need more help.

    I had completely forgotten about NasalCrom. I took it in the early ’80s and it worked like a champ! Wow. This was a blast from the past and I’m glad I read it. I incorrectly thought it was an antihistamine. I am passing this article along to a friend whose mother has tried everything.

    I have used cromolyn inhalers (Intal) for years through a spinhaler..and loved it! No steroids! Then, it was no longer offered in the proper dose, with the advent of a myriad of steroid inhalers hitting the market.

    NasalCrom works as promised, too, and it is definitely worth trying FIRST before adding steroids!

    Thanks so much for posting this advisory!!

    I read your piece on NasalCrom with keen interest. I am allergic to pet dander and ragweed, among other things. I take cetirizine daily to allow me to be near my son’s dogs (whom I love) and to function outdoors. I read that NasalCrom can have long-term negative effects on nasal mucosa (“Benzalkonium chloride in nasal decongestive sprays has a long-lasting adverse effect on the nasal mucosa of healthy volunteers.”
    Hallén H, et al. Clin Exp Allergy. 1995.) I would appreciate your comments on this study.

    I used cromolyn for a year in the early 90’s and complained many times to my allergist who had prescribed it that it burned my nose. He insisted that I keep using it, even saying “his family used it and had no problem”. I stopped it on my own but by the time I did, I had lost most of my sense of smell which never recovered. No cromolyn for me!!!

    I’ve been using Nasalcrom for years. It’s one of the three or four sprays that I do use. I also use XClear and a homeopathic spray. I recently found Rebound which helps with congestion, but I try not to let it get that far.

    Has anyone tried this and how did it work for you?

    Nasal Chrom WORKS ! The down side of it is actually an up side. Using it conveniently 4 times a day provides rinsing, nasal moisture AND mast cell control. I have used it when first signs of nasal allergy comes along for several years. It also avoids almost inevitable nasal tissue rebound from a product like AFRIN.

    Another really helpful, extended use, maintainance, nasal spray is, in my experience, X Clear. It too rinses / moisturizes and, in my experience, promotes sinus and ear drainage. It can be used along with other nasal treatments. The X refers to XYLITOL which, in chewing gum, has been reported to help children with clearance of mucous in the ears.

    With NasalChrom and X Clear I have dropped all but rare use of regular allergy capsules.

    I used Nasalcrom for several years around 2000. It worked as advertised, but during that period I almost totally lost my sense of smell. That’s the reason I stopped using it. I can still smell a skunk, but little else. A few years ago I scanned the web for any mention of a class action lawsuit, but I didn’t find one. I did find one for something that looked like a similar product.

    I have used Nasalcrom (first prescribed by an allergist) and have found it superior to all the others. But sometimes it is not in stock and has to be ordered.

    I also had severe sinus congestion, in my upper sinuses. This clear, viscous material would suddenly drain for an hour every 24 or 36 hours. Terrible! I cured it in 1 week with anti-fungal medication!

    Back in the ’90’s I suffered from allergies, especially in the fall. I would use Duration nasal spray and became hooked on it due to the rebound congestion. I ended up having to use it year round. It became a nightmare.

    I went to my PCP, here in Arizona, and told him I had been on Duration for several years and could not get away from using it. He RX’d Cromolyn Sodium (NasalCrom) to me to break the cycle. I quit using Duration and only used NasalCrom as directed. Within two weeks, I was off Duration and no longer needed NasalCrom. It is a wonderful medicine to use.

    Toothpick weed is amivisnaga, and like many in the carrot family, it is hard to tell the difference between the toxic species and the beneficial and edible plants. That said, there is some literature on the use of this herb to treat kidney stones as well as asthma. Wonder what big Pharma got the patent on that??

    Just googled it…it is not the same as the ornamental Bishop’s weed, ska snow on the mountiain…which in some state with (IMO)picky conservationists, is listed as a noxious weed because it spreads fast.

    A perennial called Bishops Weed is a common garden plant around here…would planting it around the porches help I wonder??

    I’ve used (and recommended) Nasalcrom since 1980(!) when it was a prescription medication. My wonderful doctor in Houston found it looking for something his daughter could use that was safe and effective. It is so safe, the accompanying literature states, pregnant women can use it. It does not interact with other medications.

    I still use it. The prescription was stronger, but much more expensive. Now it is very reasonable, but you may have to use more often. I recommend it often. Since it’s “over the counter” now and inexpensive compared to the newer allergy sprays, it’s definitely worth a try.

    I have had allergies for years, and Allegra has been used. But this season, I was hit really, hard. I just turned 80, and have Glauoma, so I have to be careful. My doc prescribed Prednisone because I was so inflammed and it was affecting my scarred lungs. I have tried over the counter stuff, and nothing is helping. I guess I can get this at the drug store. I will certainly give it a try. Thanks.

    This article left me curious about the role of mast cells in atopic eczema, and whether cromolyn would be helpful if applied topically to eczema rashes. Any thoughts?

    Dear Sir/madam,
    I was using Cromolyn nasal drops. At this time, it is NOT available in the US. Has it been re-introduced in the market? Please let me know. Thanks.

    I’ve not tried NasalCrom, but I’ve gotten good results with Xlear Nasal Spray (with xylitol). Do you have any comments on Xlear? Thank you.

    Can you use NasalCrom in combination with other products?

    My ENT doctor told me to use Nasalcrom because I have glacoma and had to avoid steroid nasal sprays. After I had used two bottles of Nasalcrom I lost my sense of smell. That was 3-4 years ago and I still can’t smell.

    I’ve been using NasalCrom for years and love it. I have reactions to steroid sprays, this simply encapsulates the histamines so they don’t make one’s eyes and nose run, and it has virtually no side effects, nor does it have adverse consequences with other medications.

    I use NasalCrom twice a day during the pollen season, and it works extremely well. My Dr. suggested this over-the-counter spray, and it can be purchased at Bartell’s. I haven’t found it anywhere else in our region. I’d give this med a five star.

    I started using NasalCrom over a year ago. I use it 2 to 3 times a day. My allergies are very bad. I have seasonal allergies and am allergic to tree and weed pollen as well as indoor allergies to dust mites and my cats. I sneeze all year round. I have been on allergy shots for years and took numerous medications, including Zyrtec.

    I have been wanting to get off of Zyrtec but didn’t know how. Other antihistamines were not as effective. Since I have been using NasalCrom, I have had zero symptoms from allergies. I am now to the point where I feel confident enough to try getting off of Zyrtec. This is by far the best nasal spray for me. Very happy to have found it.

    NasalCrom is a life saver. I use it only when I get a nasal “itch” and it work immediate wonders. No side effects. No dependencies.

    EXCELLENT stuff, NasalCrom! I’ve been using it for years, and recommending it to anybody who will listen. So much better than antihistamines and OTC nasal sprays.

    Thank you for featuring it: it deserves to be better known.

    (PS: I live in the pollen-covered South. ?)

    I have been taking Quercetin for since 2002 and have had zero problems with allergies since. Before 2002 I was miserable, headaches, itchy eyes, running nose, tears, tears, tears.

    With Quercetin it has to be built up in the system. I take it daily; I started two months before allergy season initially every day and since. I recommend it.

    Wondering how effective Nasalcrom is on allergic asthma? Is it strong enough to maybe prevent an attack and does it interact with emmergency inhalers if the problem is not solved?
    Sometimes I think my asthma begins with allergies mold or trees, and often leads to ER visit in spite of my rescue inhaler.

    Thanks and I love your column!

    Can you use NasalCrom if you have glaucoma?

    Is it safe for kids? My 8 yo granddaughter suffers miserably from allergies

    I have been on corticosteroid nasal sprays for 40 years and sometimes they stop working. I use Nasacrom and it gets me back on track. Ann H.

    Just wondering if it would help for pet allergies and household dust.

    Effective, but uncomfortable to use.

    I used it as a prescription in the 80’s and 90’s. One negative is that it is very watery and runny making me feel like I had snuffed water up my nostrils. Like I was drowning. That is why I prefer Fluticasone. It is thicker, less watery, and works just as well.

    I tried NasalCrom when it first came out but I think I didn’t use it long or often enough, and it didn’t work. Thanks for writing about it. My allergy meds never work completely during the heavy pollen times, and I can’t take shots because after years of effective shots I had an anaphylactic reaction. I didn’t realize it’s over-the-counter now, and I’m going to try it.

    In the mid 2000’s I was experiencing a recurring cycle of sinus infections. For years I was cycling on and off of antibiotics, Cipro,Levaquin, Avalox. I remember multiple cycles of 30 days on Levaquin. To keep the symptoms at bay and to be able to work, I used OTC cold remedies but nothing was working. I have since learned that so many antibiotics actually perpetuate the problem.

    I went through allergy tests, immune factor tests, and other treatments with no results. My immunologist specialist gave up, and as a whim, on my way out the door he suggested nasalcrom. It saved my life and allowed me to get back in balance and I no longer suffer from nasal infections. I now use it very infrequently during pollen season.

    Yes!!!!!!!! Finally: more discussion about this remedy. And you do have to use about 4x/day. GO GET IT!!
    Only ONE of my regular respiratory doctors (not my ENT nor pulmonologist nor osteologist) – my recent allergist – made me aware of cromolyn sodium! She called it “old fashioned.” Well, if it ain’t broke…

    I first (and still do) used it nebulized, then discovered nasal spray brand NasalCrom. It is soooooo good. I did my own research after my 3rd – yes, 3rd polyp removal surgery (July 2016) and confirmed my experience using the spray. IT WORKS, and my polyps are smaller: I no longer trust my ENT doctor; still have to have that “chat” with him. Last week I had my drug store order more just for me to always have it on hand.
    THANK YOU!?!!

    I have been using Nasal Crom since it was a prescription med and it has proven not merely effective, but so effective I will forget to use it every now and then. The one thing about all these other nose sprays is, when you need to use them they let you know via sneezing, drippy nose, etc, but with Nasal Crom just becaause you forgot to spray one or two times the effects last long enough for you to remember without having to suffer the indignities of allergy season.
    I begin in mid-February/early march, depending how long Winter hangs around, and then finish up in mid- June or so.
    As far as I am concerned this is the greatest stuff, ever, and when I stop using it, presuming my timing is right-on, my nose doesn’t run again unless I get a cold before the next Spring.
    I used to sort of dread Spring with its several months of pollen, now I look forward to it again.
