Allergy Headaches Causes and Treatment

  • Sometimes, allergies associated with sinus disease can cause headaches. It always makes sense to discuss taking any medication with your doctor, you can address certain allergies and allergy-related symptoms such as headaches with preventive steps and over-the-counter medications. When the allergies get to an extent where they are interfering with your day-to-day activities, consult with your doctor for a complete diagnosis and possibly a referral to an allergist.



    Can allergies cause headaches?


    Yes. Headache is a very common problem. Research estimates 70 to 80 per cent of us experience headaches, and about half of that experience at least once a month. Allergies can be the source of some of those headaches.


    Which allergies cause headaches?


    Here is a list of the common allergies that can lead to headaches-


    • Allergic rhinitis (hay fever) – when a headache occurs along with indoor nasal allergies and seasonal allergies, it is more likely a migraine headache rather than allergies. Whereas pain with hay fever or other allergic reactions may cause headaches because of sinus disease. A true sinus headache is quite rare.
    • Food allergies- There can be headaches due to some types of food such as aged cheese, artificial sweeteners, and chocolate can trigger a migraine in some people. Experts say it’s due to the chemical properties of certain foods as opposed to a true food allergy.
    • Histamine- when the body makes histamines in response to an allergic reaction, histamines decrease blood pressure and thus it can result in headache.




    Treating an allergy headache is not different than the one you deal with another headache. If allergies are the root cause of the headache, there are possible treatments to address the root cause.


    How to Prevent Allergy Headache?


    If a person knows that he or she is prone to allergy, they can best avoid the allergens to lower your chances of getting an allergy-related headache.


    There are ways to avoid your allergy triggers if they are airborne, as listed below-


    • Remove carpeting from your living space.
    • Install a dehumidifier.
    • Keep your furnace filter clean.
    • Vacuum and dust your house regularly.
    • Medication


    Here’s a list of allergies that respond to over-the-counter (OTC) antihistamine medications. These include:


    • Diphenhydramine (Benadryl)
    • Chlorpheniramine (Chlor-Trimeton)
    • Cetirizine (Zyrtec)
    • Loratadine (Claritin)
    • Fexofenadine (Allegra)


    There are available OTC and by prescription. They include-

    • Fluticasone (Flonase)
    • Budesonide (Rhinocort)
    • Triamcinolone (Nasacort AQ)

    You can treat your allergies by allergy shots. They may lower the chances of allergy headaches by decreasing your sensitivity to allergens and reducing allergy attacks. These are injections given under your doctor’s supervision.


    When to see the doctor?


    Although many allergies can be controlled with the judicial use of OTC medications, it’s always a good idea to consult with your doctor. If allergies are negatively affecting your quality of life or interfering with your daily activities, it’s best to explore treatment options with your doctor. Your doctor might recommend that you see an allergist. This is a physician specializing in diagnosing and treating allergic conditions, such as asthma and eczema.
