First, your doctor will figure out what you’re allergic to.
The doctor will examine you and take your medical history and your family’s allergy history. Then she may do a series of skin tests or a blood test to see what you have a reaction to. That will help decide which treatment you should take. Or she may suggest trying an allergy medicine that can help no matter what you're allergic to. Medicines can often help with your allergies to pollen, dust, perfumes, plants, or animal dander.
Alternaria. Aspergillus. Cladosporium. Penicillium. Unless you have a special fondness for fungi, you’re probably not too familiar with these or any of the thousands of other common molds.
But if you’re among the estimated 5% of Americans who have mold allergies, you may be all too well acquainted with the itchy eyes, nasal congestion, coughing, wheezing, skin irritation, and other symptoms mold allergies can cause. Severe mold allergies can even trigger potentially dangerous asthma attacks.
With allergies, your nasal passages and sinuses get inflamed when they’re exposed to triggers like pollen, animal dander, or dust mites. Steroid nasal sprays can be effective drugs for allergies, because they ease or end inflammation. It takes a while, though. You will probably feel better -- with less swelling and mucus -- within one to two weeks of starting a nasal steroid spray. You have to use it every day to keep feeling better.
3. Do allergy shots work?
Yes, over time. They help if you’re allergic to pet dander, pollens, dust mites, certain molds, and bee stings. They work by injecting tiny amount of what you’re allergic to under your skin. At first, you’ll get shots once or twice a week. Later you’ll get shots about once a month, for a period of years. Gradually your body gets used to the allergen and your symptoms get better.
Also, the FDA has approved three under-the-tongue tablets that can be taken at home. The prescription tablets, called Grastek, Ragwitek, and Oralair, are used for treating hay fever and work the same way as shots -- the goal is to boost a patient’s tolerance of allergy triggers.
