Hay fever is an allergic reaction to pollen, usually when it comes into contact with your mouth, nose, eyes and throat. Pollen is a fine powder from plants. Hay fever is usually worse between late March and September, especially when it's warm, humid and windy. This is when the pollen count is at its highest. Check the pollen forecast on the Met Eireann website Symptoms of hay fever include: If you have asthma, you might also: Hay fever may last for weeks or months, unlike a cold, which usually goes away after 1 to 2 weeks. There's currently no cure for hay fever and you can't prevent it. But you can do things to ease your symptoms when the pollen count is high. To ease your hay fever symptoms: put Vaseline around your nostrils to trap pollen wear wraparound sunglasses to stop pollen getting into your eyes shower and change your clothes after you've been outside to wash the pollen off stay indoors whenever possible keep windows and doors shut as much as possible vacuum often dust with a damp cloth buy a pollen filter for the air vents in your car buy a vacuum cleaner with a special HEPA filter (these can trap pollutants) Don't
When to see a pharmacistSpeak to your pharmacist if you have hay fever. They can give advice and suggest the best treatments. These include antihistamine drops, tablets or nasal sprays. These treatments can help with:
When to see a GPIf you are not seeing any improvement from the pharmacist's treatment, your GP may be able to help. Visit your GP if:
Treatments from your GPYour GP may prescribe steroids. If steroids and other hay fever treatments don't work, your GP may refer you for immunotherapy. This means you'll be given small amounts of pollen as an injection or tablet. This will slowly build up your immunity to pollen. This kind of treatment usually starts in the winter about 3 months before the hay fever season begins.

Page last reviewed: 15 April 2020 SymptomsPeople with allergic rhinitis generally experience symptoms after breathing in an allergy-causing substance such as pollen or dust. In the spring, the most common triggers are tree and grass pollen. In the fall, a common allergen is ragweed or other weed pollens or outdoor mold. When a sensitive person inhales an allergen, the body’s immune system may react with the following symptoms (listed in order of frequency):
Symptoms also may be triggered by common irritants such as:
There are two types of allergic rhinitis:
Allergic rhinitis can be associated with:
Many parents of children with allergic rhinitis have said that their children are more moody and irritable during allergy season. Since children cannot always express their symptoms verbally, they may express their discomfort by acting up at school and at home. In addition, some children feel that having an allergy is a stigma that separates them from others. It is important that the irritability or other symptoms caused by allergy symptoms are not mistaken for attention deficit disorder. With proper treatment, symptoms can be kept under control and disruptions in learning and behavior can be avoided. Symptoms of allergic rhinitis have other causes as well, the most customary being the common cold – an example of infectious rhinitis. Most infections are relatively short-lived, with symptoms improving in three to seven days. Many people have recurrent or chronic nasal congestion, excess mucus production, itching and other nasal symptoms similar to those of allergic rhinitis. In those cases, an allergy may not be the cause. DiagnosingOccasional allergies aren’t just something you have to live with. Consulting an allergist is the most effective way to diagnose and treat allergic rhinitis symptoms and help you find relief. Your allergist may start by taking a detailed history, looking for clues in your lifestyle that will help pinpoint the cause of your symptoms. You’ll be asked, among other things, about your work and home environments (including whether you have a pet) your family’s medical history and the frequency and severity of your symptoms. Sometimes allergic rhinitis can be complicated by several medical conditions, such as a deviated septum (curvature of the bone and cartilage that separate the nostrils) or nasal polyps (abnormal growths inside the nose and sinuses). Any of these conditions will be made worse by catching a cold. Nasal symptoms caused by more than one problem can be difficult to treat, often requiring the cooperation of an allergist and another specialist, such as an otolaryngologist (ear, nose, and throat specialist surgeon). Your allergist may recommend a skin test, in which small amounts of suspected allergens are introduced into your skin. Skin testing is the easiest, most sensitive, and generally least expensive way of identifying allergens. Types of skin tests
Management and TreatmentAvoidanceThe first approach in managing seasonal or perennial forms of allergic rhinitis or hay fever should be to avoid the allergens that trigger symptoms, if possible. Outdoor exposure
Indoor exposure
Exposure to pets
MedicationsMany allergens that trigger allergic rhinitis are airborne, so you can’t always avoid them. If your symptoms can’t be well-controlled by simply avoiding triggers, your allergist may recommend medications that reduce nasal congestion, sneezing, and an itchy and runny nose. They are available in many forms – oral tablets, liquid medication, nasal sprays and eyedrops. Some medications may have side effects, so discuss these treatments with your allergist so they can help you live the life you want. Intranasal corticosteroidsIntranasal corticosteroids are the single most effective drug class for treating allergic rhinitis. They can significantly reduce nasal congestion as well as sneezing, itching and a runny nose. Ask your allergist about whether these medications are appropriate and safe for you. These sprays are designed to avoid the side effects that may occur from steroids that are taken by mouth or injection. Take care not to spray the medication against the center portion of the nose (the nasal septum). The most common side effects are local irritation and nasal bleeding. Some older preparations have been shown to have some effect on children’s growth; data about some newer steroids don’t indicate an effect on growth. AntihistaminesAntihistamines are commonly used to treat allergic rhinitis. These medications counter the effects of histamine, the irritating chemical released within your body when an allergic reaction takes place. Although other chemicals are involved, histamine is primarily responsible for causing the symptoms. Antihistamines are found in eyedrops, nasal sprays and, most commonly, oral tablets and syrup. Antihistamines help to relieve nasal allergy symptoms such as:
There are dozens of antihistamines; some are available over the counter, while others require a prescription. Patients respond to them in a wide variety of ways. Generally, the newer (second-generation) products work well and produce only minor side effects. Some people find that an antihistamine becomes less effective as the allergy season worsens or as their allergies change over time. If you find that an antihistamine is becoming less effective, tell your allergist, who may recommend a different type or strength of antihistamine. If you have excessive nasal dryness or thick nasal mucus, consult an allergist before taking antihistamines. Contact your allergist for advice if an antihistamine causes drowsiness or other side effects. Proper use: Short-acting antihistamines can be taken every four to six hours, while timed-release antihistamines are taken every 12 to 24 hours. The short-acting antihistamines are often most helpful if taken 30 minutes before an anticipated exposure to an allergen (such as at a picnic during ragweed season). Timed-release antihistamines are better suited to long-term use for those who need daily medications. Proper use of these drugs is just as important as their selection. The most effective way to use them is before symptoms develop. A dose taken early can eliminate the need for many later doses to reduce established symptoms. Many times, a patient will say that he or she “took one, and it didn’t work.” If the patient had taken the antihistamine regularly for three to four days to build up blood levels of the medication, it might have been effective. Side effects: Older (first-generation) antihistamines may cause drowsiness or performance impairment, which can lead to accidents and personal injury. Even when these medications are taken only at bedtime, they can still cause considerable impairment the following day, even in people who do not feel drowsy. For this reason, it is important that you do not drive a car or work with dangerous machinery when you take a potentially sedating antihistamine. Some of the newer antihistamines do not cause drowsiness. A frequent side effect is excessive dryness of the mouth, nose, and eyes. Less common side effects include restlessness, nervousness, overexcitability, insomnia, dizziness, headaches, euphoria, fainting, visual disturbances, decreased appetite, nausea, vomiting, abdominal distress, constipation, diarrhea, increased or decreased urination, urinary retention, high or low blood pressure, nightmares (especially in children), sore throat, unusual bleeding or bruising, chest tightness or palpitations. Men with prostate enlargement may encounter urinary problems while on antihistamines. Consult your allergist if these reactions occur. Important precautions:
DecongestantsDecongestants help relieve the stuffiness and pressure caused by swollen nasal tissue. They do not contain antihistamines, so they do not cause antihistaminic side effects. They do not relieve other symptoms of allergic rhinitis. Oral decongestants are available as prescription and nonprescription medications and are often found in combination with antihistamines or other medications. It is not uncommon for patients using decongestants to experience insomnia if they take the medication in the afternoon or evening. If this occurs, a dose reduction may be needed. At times, men with prostate enlargement may encounter urinary problems while on decongestants. Patients using medications to manage emotional or behavioral problems should discuss this with their allergist before using decongestants. Patients with high blood pressure or heart disease should check with their allergist before using. Pregnant patients should also check with their allergist before starting decongestants. Nonprescription decongestant nasal sprays work within minutes and last for hours, but you should not use them for more than a few days at a time unless instructed by your allergist. Prolonged use can cause rhinitis medicamentosa or rebound swelling of the nasal tissue, leading to more frequent congestion and need to re-dose medication more frequently than recommended. Stopping the use of the decongestant nasal spray will cure the swelling if there is no underlying disorder. Other nasal spraysNonprescription saline nasal sprays will help counteract symptoms such as dry nasal passages or thick nasal mucus. Unlike decongestant nasal sprays, a saline nasal spray can be used as often as it is needed. Sometimes an allergist may recommend washing (douching) the nasal passage. There are many OTC delivery systems for saline rinses, including neti pots and saline rinse bottles. Nasal cromolyn (Nasalcrom) blocks the body’s release of allergy-causing substances. It does not work in all patients. The full dose is four times daily, and improvement of symptoms may take several weeks. Nasal cromolyn can help prevent allergic nasal reactions if taken prior to an allergen exposure. Nasal ipratropium bromide spray (Atrovent) can help reduce nasal drainage from allergic rhinitis or some forms of nonallergic rhinitis. Another prescription nasal spray option is an intranasal antihistamine. These medications, such as azelastine (Astelin) or olopatadine (Patanase), are older antihistamines with some allergy cell stabilizing properties that can be used alone or with other medications including oral antihistamines and intranasal steroids. One nice feature of these medications is that they work quickly enough that they can be used as needed rather than every day. They can also help relieve nasal congestion and post nasal drainage but can cause sedation in some patients. Azelastine in particular may have an unpleasant taste. Leukatriene pathway inhibitorsLeukotriene pathway inhibitors (montelukast, zafirlukast and zileuton) block the action of leukotriene, a substance in the body that can cause symptoms of allergic rhinitis. These drugs are also used to treat asthma and are only available by prescription. Montelukast was recently given a warning from the FDA regarding potential behavioral changes. ImmunotherapyImmunotherapy may be recommended for people who don’t respond well to treatment with medications or who experience side effects from medications, who have allergen exposure that is unavoidable or who desire a more permanent solution to their allergies. Immunotherapy can be very effective in controlling allergic symptoms, but it doesn’t help the symptoms produced by nonallergic rhinitis. Two types of immunotherapy are available: allergy shots and sublingual (under-the-tongue) tablets.
Eye allergy preparations and eyedropsEye allergy preparations may be helpful when the eyes are affected by the same allergens that trigger rhinitis, causing redness, swelling, watery eyes and itching. OTC eyedrops and oral medications are commonly used for short-term relief of some eye allergy symptoms. They may not relieve all symptoms, though, and prolonged use of some of these drops may cause your condition to worsen. Prescription eyedrops and oral medications also are used to treat eye allergies. Prescription eyedrops provide both short- and long-term targeted relief of eye allergy symptoms. Check with your allergist or pharmacist if you are unsure about a specific drug or formula. Treatments that are not recommended for allergic rhinitis
Occupational RhinitisIf you develop symptoms that resemble those of hay fever and that appear or become more serious at work, you may be suffering from occupational rhinitis. Occupational rhinitis, or work-related rhinitis, is a condition in which symptoms are triggered or further aggravated by allergens in the workplace. These symptoms can include sneezing, a runny nose and watering eyes. Common triggers include cleaning products, chemical fumes, certain types of dust, and corrosive gases. If your allergy symptoms appear at work, or seem to get worse there, ask your allergist to help you identify potential triggers and develop a treatment plan.
