How do Cockroaches cause Allergy symptoms?

Allergy_Cockroach_1The allergens produced by cockroaches are likely concentrated in their faecal matter and in fragments of their body parts. These tiny particles can become airborne and contaminate the air in your home. Cockroach allergens behave like dust mite allergens. These allergens do not remain airborne for long. Activities like dusting and dry mopping may stir up allergens that have settled in dust or fabrics. The most common way to inhale cockroach allergen is to breathe in dust or allergens that have collected in pillows, bedding or other dust-trapping fabrics.

Your allergist will review your medical history, ask questions about your symptoms and possible allergens. He or she may do skin testing and/or test your blood. With skin testing, a small amount of a possible allergen is pricked or scratched into the skin. If you’re sensitive to an allergen, a small red lump appears on the skin where that substance was placed.

How is Cockroach Allergy treated?

Take steps to prevent or get rid of cockroaches.

Take medicine to relieve your symptoms. Your allergist may prescribe medicines such as antihistamines, decongestants, nose (nasal) sprays, or eye drops for allergy symptoms and asthma medicine for asthma symptoms.

Get allergy shots, if the allergist suggests you get them. Some people need them when they can’t avoid an allergen. The shots contain a tiny but increasing amount of the allergen you’re sensitive to. Over time, your body becomes used to the allergen and no longer reacts to it.
