  • NyQuil

What do I need to know if my child was prescribed EMLA cream before our allergy test?

If your child has been prescribed EMLA cream for their allergy test, follow these helpful tips before your appointment:

  • Apply the cream one hour before the appointment
  • Apply the cream from the top of the shoulders all the way down to the pant line, and across.
  • It is a cream; however, it is not meant to be rubbed in like a typical cream, please apply a thin layer.
  • Once you are finished with the application, you should place plastic cling wrap on the back to ensure the medication stays in place.
  • You may also use medical tape or Band-Aids to keep the wrap in place.

We look forward to helping you on your path to allergy relief!

What's the difference between drops and shots? 

Allergy drops are just as effective as shots and have the same timeline of treatment.

The areas where drops and shots differ are in safety and convenience. Shots have a risk of putting the patient into anaphylatic shock, but drops do not have that risk. Shots also require a weekly trip to your allergist for a painful injection followed by 30 minutes of sitting around before you can leave (due to the risk of anaphylatic shock outside of medical attention).
