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.
Physical exam. Your doctor will carefully check you -- especially your skin, if you have a rash or hives.
Questions. Be ready to answer a lot of questions. Your doctor will want details about the medicines you've been using, your symptoms, and your health.
Blood tests. If you’ve had a serious skin reaction, your doctor may ask for these to be sure your organs are all working right or to look for other signs of a true allergy.
Other tests. Depending on your case, your doctor may need other tests, like a chest X-ray.
Treatment. If your symptoms are bad, your doctor will give you medicine to control the reaction.
Diagnosing and Managing a Drug Allergy
After the exam, your doctor may suggest:
Switching drugs. If your doctor is sure you are allergic to a drug, he or she will have you stop that drug and may switch you to a different medicine.
Allergy testing. If there's any doubt about whether you are truly allergic, your doctor may want you to have more tests. Keep in mind the tests don’t work for all drugs.
Trying to reduce your reaction. If switching drugs isn't an option -- and you must keep taking a drug for your health -- your doctor may suggest something called desensitization. You would get a small dose of the drug and then gradually raise it. The slow increase may get your body more used to the drug and cut your risk of an allergic reaction. It’s done in the hospital or doctor’s office. Desensitization is not a cure. It’s only temporary. It doesn't work for everyone and has risks. But it's one way for you to keep getting a medicine you need.
If you have an allergy, your doctor will give you advice on how to protect yourself. Some good first steps include:
Memorize the name of the drug that you’re allergic to -- both brand names and generic. Make sure that all your other health care providers, dentists, and pharmacists know about your drug allergy.
Get a medical ID bracelet or necklace that states your drug allergy. Always wear it.
Know what to do if you have an allergic reaction. If your doctor prescribes medication -- like Auvi-Q or Epi-Pen (epinephrine shot) -- for emergencies, make sure you know how to use it.
