    Drug Allergies: What to Expect From a Doctor

    Doctors are careful when diagnosing a drug allergy. Allergic reactions to drugs are different from more common drug side effects and can mimic some other conditions.

    Could It Be an Allergy?

    Wondering if your nagging cold is actually an allergy? Or what about your new skin cream that made your hands break out? Distinguishing an allergy from a non-allergic condition is not always a clear-cut task. But knowing the difference can sometimes help you solve what's ailing you, which in turn could mean faster relief. Mary Fields knows just how difficult pinpointing an allergy can be.

    A physical exam : Your doctor will carefully check you -- especially your skin -- to see if you have a rash or hives.

    Blood tests: If you’ve had a serious skin reaction, your doctor may ask for these to check how your organs are working and to see if there are any other signs of an allergic reaction.

    Other tests: Depending on your case, your doctor may need to see some other things, like a chest X-ray.

    Treatment: If your symptoms are severe, your doctor will give you medicine to help control the reaction.

    Diagnosing and Managing a Drug Allergy

    After the exam, your doctor may suggest:

    Switching drugs: If your doctor thinks you are allergic to a drug, he will have you stop using that drug and may switch you to a different one.

    Allergy testing : If there's any doubt if you are truly allergic, he may want you to have more tests. Keep in mind that 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 it would be raised gradually. The slow increase may get your body more used to the drug and lower 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 it has risks. But it's one way for you to keep getting a medicine you need.

    Taking Care

    If you have an allergy, your doctor will advise you on how to protect yourself. Some good first steps include:
