Managing Allergies at Work
It's hard enough to cope with allergies on the weekend, but dealing with
allergies at work is even more challenging.
Ask anyone who's ever dozed off in the middle of an important meeting
because of allergy symptoms or medications.
"Allergy symptoms are the No. 2 reason adults miss work," says James
Sublett, MD, a board-certified asthma and allergy specialist in Louisville,
The average worker with allergies misses about one hour per week over the
course of a year. But that sick time is...

In this article, you'll learn the symptoms of mild allergic reactions and an anaphylactic reaction. You'll also find out what to do if a child has anaphylaxis.
Allergy Symptoms: What's Normal
Kids with mild allergies (such as seasonal allergies) will usually have these symptoms:
Watery, runny eyes Runny nose Sneezing Nasal congestion An itchy rash or hives
These symptoms usually aren't serious. But stay on the lookout for more serious allergy symptoms (see below), especially in kids who have a history of asthma and severe allergic reactions.
Watch for these anaphylaxis symptoms and call 911 right away if you notice:
Difficulty breathing or noisy breathing Hives Swelling of the throat, face, lips, or tongue Tightness in the lungs Wheezing Hoarseness Pale or flushed skin Sweating Weak, rapid pulse Low blood pressure Dizziness, fainting Nausea, vomiting Abdominal pain What Causes Anaphylaxis?
Many cases are caused by food allergies or insect stings.
In anaphylaxis, a child has a severe reaction to an allergy trigger.
Their airways narrow and their throat swells, which can block breathing. Their blood vessels widen, making their blood pressure fall, sometimes to dangerous levels.
Anaphylactic reactions usually happen fast. Symptoms often get the most severe within three to 30 minutes of exposure to the allergy trigger. Quicker reactions are usually more severe.
A child who has had a severe allergic reaction should carry an emergency kit that includes an epinephrine auto-injector such as Auvi-Q or EpiPen.
You should know how to use the injector. So should your child's teacher. Your child may also be old enough to use it on themselves. Ask your child's doctor about that.
As soon as possible after the allergic reaction starts, give the child at least one shot of epinephrine. They may need more epinephrine injections.
The epinephrine injection is not a cure. It will not stop a severe allergic reaction. Even if the child seems OK, emergency medical care is a must.
Restock any items you used from the emergency kit so it's ready at all times. Check expiration dates on each epinephrine injection. Like all drugs, epinephrine has an expiration date.
