In order to minimize the risk of an allergy shot reaction we want to remind all of our allergy shot patients to please take the following steps:

1. Make sure you take your antihistamine medication in the morning before coming in for your allergy shot.

2. Before getting your allergy shot please let the shot nurse know if you have been having a bad allergy or asthma flare this week.

3. Please remain in the waiting room for at least 30 minutes after your shot. Most allergy shot reactions occur within the first 30 minutes post-injection.

4. Make sure your epinephrine auto-injector (Epipen) is easily accessible and that you know how to use it should you develop an allergy shot reaction after leaving the office.

Let's keep this a safe and effective experience!
