Prevention
Avoiding exposure to pollen is the best way to decrease allergic symptoms.

Remain indoors in the morning and evening when outdoor pollen levels are highest.
Wear face masks designed to filter out pollen if you must be outdoors.
Keep windows closed and use the air conditioner if possible in the house and car.
Do not dry clothes outdoors.
Avoid unnecessary exposure to other environmental irritants such as insect sprays, tobacco smoke, air pollution, and fresh tar or paint.
Avoid mowing the grass or doing other yard work, if possible. Avoid fields and large areas of grassland.
Regular hand- and face-washing removes pollen from areas where it is likely to enter the nose.
A small amount of petroleum jelly around the eyes and nostrils will stop some pollen from entering the areas that cause a reaction
Avoid bicycling or walking - instead use a method of confined transportation such as a car.

Treatment:
The goal of treatment is to reduce allergy symptoms caused by the inflammation of affected tissues. The best "treatment" is to avoid what causes your allergic symptoms in the first place.


Medication:
The most appropriate medication depends on the type and severity of symptoms. Specific illnesses that are caused by allergies (such as asthma and eczema) may require other treatments.

Options include the following:

Fast-acting strong antihistamines such as drugs including chlorphenamine which relieve the symptoms after a hayfever "attack".
Short-acting antihistamines, which are generally over-the-counter (non-prescription), often relieve mild to moderate symptoms, but can cause drowsiness. A pediatrician should be consulted before using these medicines in children, as they may affect learning. One formerly prescription medication, loratadine (Claritin®), is now available over the counter in many countries. It does not tend to cause drowsiness or affect learning in children. Azelastine (Astelin®) is the only antihistamine available as a nasal spray.
Longer-acting antihistamines cause less drowsiness, can be equally effective, and usually do not interfere with learning. These medications include fexofenadine (Allegra), and cetirizine (Zyrtec).
New leukotriene receptor antagonists, such as montelukast (Singulair) and zafirlukast (Accolate) have proven very effective in dealing with allergic rhinitis, without the common side-effects of the first-generation antihistamines, such as drowsiness. These medicines are also long-acting, and are recommended to be taken once-daily.
Corticosteroid nasal sprays are effective and somewhat safe, and may be effective without oral antihistamines. These medications include fluticasone (Flonase/Flixonase), budesonide (Rhinocort), flunisolide (Syntaris), mometasone (Nasonex), triamcinolone (Nasacort) and beclomethasone (Beconase®).
Topical decongestants may also be helpful in reducing symptoms such as nasal congestion, but should not be used for long periods as stopping them after protracted use can lead to a rebound nasal congestion (Rhinitis medicamentosa).
Cromolyn sodium (or cromoglycate) is a drug that stabilizes mast cells and prevent their degranulation and subsequent release of histamine. It is available as a nasal spray (Nasalcrom) for treating hay fever. Eye drop versions of cromolyn sodium (Crolom) are available for allergic conjunctivitis.
"Allergy shots" (Hyposensibilization, immunotherapy) are occasionally recommended if the allergen cannot be avoided and if symptoms are hard to control. This includes regular injections of the allergen, given in increasing doses (each dose is slightly larger than the previous dose) that may help the body adjust to the antigen. These tend to be offered as a last resort as the therapy is more expensive at first, although patients may save money on medications and doctor visits in the long run. They may also increase the risk of triggering a secondary allergic reaction such as an asthma attack.
A large number of over-the-counter treatments are sold without FDA approval but are known for their positive effects, including herbs like eyebright (Euphrasia officinalis), nettle (Urtica dioica), and bayberry (Myrica cerifera), which have not been shown to reduce the symptoms of nasal-pharynx congestion. In addition, feverfew (Tanacetum parthenium) and turmeric (Curcuma longa) has been shown to inhibit phospholipase A2, the enzyme which releases the inflammatory precursor arachidonic acid from the bi-layer membrane of mast cells (the main cells which respond to respiratory allergens and lead to inflammation) but this is only in test tubes and it is not established as antiinflammatory in humans.
