9 FAQs About Allergy Relief

5. What are allergy triggers, and how do I avoid them?

Getting rid of the things you’re allergic to at home or at work will help. Look for things like pet dander, dust mites, cold air (air conditioning vent or ceiling fan), cigarette smoke, perfume or other scented products, and aerosols. Pay attention to pollen counts.

If you have both allergies and asthma, use an air filtration system at home.

6. What's the difference between an allergy and an allergen?

The allergen is the trigger -- the thing you’re allergic to. With an allergy, you may sneeze, cough, wheeze, itch, or have a skin rash.

7. What are some common allergens?

The ones that cause most trouble are pollen (weeds, tree, grass), mold and mildew, dust mites, pet dander, cockroaches, feathers, industrial chemicals, foods (shellfish, eggs, milk, wheat, nuts), medications (aspirin, penicillin), and food additives and preservatives.

8. What if I have allergy symptoms just a few weeks a year?

You have probably seasonal allergies, or hay fever. Blame trees in the spring, grasses in summer, or weeds in the early fall. Outdoor mold also can trigger seasonal allergies.

9. Both my husband and I have allergy symptoms all the time. Will our baby have allergies, too?

It’s more likely. If one parent has allergies, the child has a 50% chance of also having allergies. If both parents have allergies, the probability jumps to 75%. But it’s not just from Mom and Dad. Respiratory infections, air pollution, diet, and even personality may play a role.
