Allergy Drugs: Prescription and OTC »
The arsenal of allergy drugs includes dozens of medications that relieve allergy symptoms when confronted with a trigger known as an allergen. That trigger could be something from a plant, such as pollen, or something from an animal (pet dander, dust mites, cockroaches). Other allergy triggers include certain fragrances or chemical substances.
What causes a person's allergic reaction is highly individual. But the reactions are often universal: swelling and inflammation, especially around the eyes, nose, and throat, usually accompanied by itching.
Some allergy medications work against the effects of histamines, which are released during an allergic reaction. Other medications reduce swelling, affect the immune system, or affect release of other substances associated with allergic reactions.
Many allergy drugs are available without a prescription.

The adverse events rates listed below are based on symptoms spontaneously reported in multidose controlled clinical trials in comparing flunisolide nasal solution (29 mcg per spray) and flunisolide nasal solution (flunisolide nasal spray .025%) (25 mcg per spray) for treatment of allergic rhinitis. In patients receiving flunisolide nasal solution (flunisolide nasal spray .025%) the most common adverse events were transient aftertaste (17%) and transient nasal burning and stinging (13%). These symptoms did not usually interfere with treatment.
Respiratory: Nasal burning/stinging (13%), epistaxis*, nasal dryness, pharyngitis, cough increased
Gastrointestinal: Nausea
Special Senses: Aftertaste (17%)
Respiratory: Hoarseness
Special Senses: Abnormal sense of smell
Respiratory: Sinusitis
Respiratory: Nasal burning/stinging (44%), epistaxis*, nasal dryness*, pharyngitis*, cough increased
Gastrointestinal: Nausea
Special Senses: Aftertaste (8%)

* Incidence of reported reaction between 3% and 9%. Those reactions occurring
in less than 3% of the patients are unmarked.
+ Reactions occurred under circumstances where the casual relationship has not
been clearly established; they are presented as alerting information for physicians.
Cases of growth suppression have been reported for intranasal corticosteroids (including flunisolide nasal solution) (see PRECAUTIONS, Pediatric Use section).
