hay fever
Etymology: AS, heawan, to hew; L, febris, fever
, Usage notes: informal.
an acute, seasonal, allergic rhinitis stimulated by tree, grass, or weed pollen. Also called pollen coryza, pollinosis. See also allergic rhinitis, organic dust.
hay fever
an atopic allergy characterized by sneezing, itching and watery eyes, nasal discharge, and a burning sensation of the palate and throat. It is a localized anaphylactic reaction to an extrinsic allergen, usually pollen or the spores of molds. When the allergen comes in contact with cell-bound immunoglobulin E in the tissues of the conjunctiva, nasal mucosa, and bronchial tree, the tissues release mediators of anaphylaxis and produce the characteristic symptoms of hay fever.
The amount of pollen in the air varies with the season and geographic area. East of the Rocky Mountains, the peak of the regional hay fever season occurs between mid-August and mid-September, when the air is heavy with the pollen of the ragweed plant. An appreciable number of hay fever sufferers are also reactive to the spring pollens from grasses and trees. Mold-bearing plants such as wheat, barley, and corn are prevalent in the agricultural areas of the Midwest, and attacks of hay fever caused by mold spores are common there as these crops ripen.
Hay fever should be recognized as more than a mere nuisance. By causing lack of sleep and loss of appetite, it can lower the body's resistance to disease. It can cause inflammation of the ears, sinuses, throat, and bronchi. Some hay fever sufferers develop asthma.
Hay fever can be relieved, although not cured, by antihistamines and sympathomimetic drugs such as ephedrine and phenylpropanolamine hydrochloride. loratadine and desloratadine are newer antihistamines that do not cause the drowsiness, mental dullness, and sleepiness that were traditionally associated with antihistamines. cromolyn is also an effective therapy, supplied in an inhaler that produces a spray of droplets to settle on the nasal mucosa and relieve symptoms of hay fever. A series of preventive injections (desensitization or hyposensitization) may be recommended in advance of the hay fever season. This consists of administering controlled and gradually increasing amounts of the offending substance in order to develop a certain amount of immunity. Air conditioning may help give relief by filtering much of the pollen from the air.

Q. Regarding Seasonal Nasal allergy. My father is suffering from seasonal nasal allergies. He took a 24-hour loratadine pill, 5 hours ago. His nose is still running just like it was. Can I take a benedryl, or is it dangerous to mix loratadine and benedryl? What else can I do to stop my nose?
A. except well known drug interactions- most Dr. check it out with a computer program they have. you need to ask a Dr. or a pharmacist about it. but i can tell you that if you wait 4 times the T1/2 - that is enough to consider the drug out of the system.
