Spring is here, which for millions of people means itchy noses, watery eyes, and nasal congestion. For many allergy sufferers, relief is often just a quick spritz away; prescription and over-the-counter (OTC) nasal sprays are one of the most common ways to treat nasal congestion caused by allergies or infection.
But for an estimated 7% of the United States population, relying too much on decongestant nasal sprays can actually cause more congestion -- a drug-induced condition called rhinitis med...
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 shots) -- for emergencies, make sure you always carry two with you and know how to use it.
