Allergy symptoms

The health effects of non-infectious bioaerosols include allergy symptoms, asthma symptoms, and hypersensitivity pneumonitis. 

Antihistamines are drags used to counteract the effects of histamine on body organs and structures. Examples of antihistamines include diphenhydramine (Benadryl), loratadine (Claritin), fexofenadine (Allegra), and cetirizine (Zyrtec). A new antihistamine, deslorata-dine (Clarinex), is die active metabolite of loratadine and is intended to eventually replace loratadine (Claritin). Topical corticosteroid nasal sprays such as fluticasone propionate (Flonase) or triamcinolone ace-tonide (Nasacort AQ) are also used for nasal allergy symptoms. See Chapter 56 for more information on die topical corticosteroids.

As a teenager Barbara moved to the Ozarks with her family. She pitched hay, cleaned animal pens and worked in the gardens without any ill effects. Feathers and dust produced no traditional allergy symptoms. 

Because people with MCS react to chemicals at levels that ordinarily do not affect others, chemical sensitivity is sometimes referred to as chemical allergy, although the mechanism is not the same as in the more traditional allergies. A person with MCS may react to animals, pollen, dust and mold with symptoms that are the same or different from those of traditional allergies. People with MCS may also have common allergy symptoms such as itchy eyes, nasal congestion, sinusitis, asthma, hives and other rashes that result from exposures to chemicals or typical allergens.

Some medicines, such as non-steroid anti-inflammatory drugs, convertase inhibitors, and (3-blockers, may intensify food allergy symptoms (Brooks et ah, 1989 Meune et ah, 2000 Tenenbaum et ah, 2000). 

Cyproheptadine (Periactin). Cyproheptadine is an antihistamine, commonly used to alleviate allergy symptoms, that also has serotonin-blocking properties. It has been successfully used to stimulate appetite in patients with medical illnesses such as cancer or AIDS. Cyproheptadine provides a small but measurable benefit in the rapidity of weight gain during the refeeding of patients with the restricting subtype of AN. However, bulimic subtype patients apparently fare worse with the addition of cyproheptadine.

Development of a Botanical Combination Product for Allergy Symptoms... 

Potential anti-allergy botanicals were first identified from the medical and eth-nopharmacological literature, from botanical products currently marketed around the world for allergy symptoms, and from discussions with raw-material suppliers. This produced a list of about 70 plant dehydrates, concentrates, or extracts. The potential ingredients were submitted to bioassay screening and regulatory review to narrow the potential active ingredients.
