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.
