  First, the allergist will get a history from you about your possible allergy. Typical questions include: How long ago did you have the reaction? What type of reaction occurred, and how soon after you took the penicillin did the reaction appear? The testing is done on the forearm by pricking the skin with a needle. If the results are negative and there is no reaction, penicillin will be injected in the skin. These tests are not painful, and results are available in 15 minutes. A positive reaction may lead to some swelling and itching where the test was placed, which usually goes away within an hour.

In very rare cases, an allergic reaction occurs. This can include hives, swelling, wheezing and/or difficulty breathing. The allergist is trained to treat this rare condition quickly if it happens. If all skin testing is negative, you may be given an oral dose of penicillin in the office. The oral drug challenge is used to verify that you don't have penicillin allergy. Usually, you'll be observed in the office for 30 minutes to make sure you have no problems.

If you find out you don't have a penicillin allergy, notify your physicians that it's now safe for you to take penicillin. They can take "penicillin allergy" off your chart for good!

My timing has always been a little off with Elizabeth Strout. I've read and pretty much admired everything she's written, but, for whatever reason, the books of hers I've picked to review
