Helping Patients Determine Whether They Have a True Drug Allergy

Our Pediatric Antibiotic Allergy Testing Program is committed to helping every child receive the safest and most effective care possible by helping children and teens find out whether they truly have an allergy to medications—most commonly antibiotics such as penicillin.

Penicillin allergy is reported by 32 million Americans. However, more than 95% of them are not actually allergic. When a patient has an unverified penicillin allergy label, it can result in longer illness, more side effects, higher costs, longer hospital stays and post-surgical site infection.

If you’ve been told your child may have a medication allergy, simple allergy testing can show if they are truly allergic.

Our Objectives

  • Diagnose: Accurately identify reason for reactions through advanced testing and clinical expertise
  • De-Label: Remove incorrect “allergy” labels to restore access to ideal medications
  • Desensitization: Safely reintroduce essential drugs when needed (confirmed reactions)
  • Discovery: Uncover new mechanisms for adverse drug reactions 

Learn more about why your child most likely does not have a penicillin allergy.

Before Your Appointment

Scheduling Your Appointment

We want it to be easy for you to get care from our program. You can contact us directly to schedule an appointment, or your doctor can send us a referral (a referral is not required). After reaching out, we will let you know whether you can be seen virtually or in person. While in-person appointments for medication challenges remain the most common approach, virtual options expand access to testing, allowing families, patients and providers to explore settings that best suit their needs.

Preparing for Your Visit

To help us prepare for your visit, we may ask you to:

  • Complete a questionnaire about your child’s past reactions
  • Share medication records and pictures from prior care related to antibiotic use
  • Pause antihistamines for allergy testing (we’ll give you clear instructions)
  • Bring a list of current medications

Our team will review everything ahead of time and design the safest approach for your child.

During Your Appointment

Our testing is simple and safe and should be offered to all children who are labeled as having an antibiotic allergy as well as other medication allergies. We offer a variety of care options to best meet your needs.

  • Outpatient Testing: New patients coming to our outpatient clinic will have testing done the same day in most cases. For example, patients with concern for penicillin allergy will take a dose of amoxicillin at the beginning of the appointment, and our allergy staff will observe them for an hour to ensure there is no reaction. Rarely, staff may perform a skin test prior to administration. Allergic symptoms during or after the challenge are infrequent (about 5% of children) and are generally mild. Children may be seen when sick with an illness, receiving their first dose of a preferred antibiotic in our office, or at a scheduled time when they are healthy. Throughout the visit, your child will be closely monitored by pediatric experts, with emergency care available immediately if needed.
  • E-Visits: E-Visits provide a convenient way to follow up after an extended challenge, home challenge or other virtual interactions—without the need for an in-person or telehealth appointment. Parents and caregivers can connect with us for follow-up questions and guidance through MyChart.
  • Testing for IV Medications: We offer a specialized clinic on the second Tuesday of every month at our Liberty location to test for allergies to IV medications such as Ceftriaxone and Vancomycin. Each appointment lasts about three hours and is designed to safely assess potential IV medication allergies without requiring hospital admission.
  • Inpatient Consultations: Children labeled with antibiotic allergies who are admitted to the hospital may be offered allergy testing or recommended to trial penicillin during hospitalization if it is the preferred antibiotic. Patients may also be referred for outpatient testing at a later date.
  • Penicillin Allergy Decision & Mobile Empowerment (PADME) tool: To begin looking into your child’s unverified penicillin allergy label, you can use the new PADME virtual risk assessment tool, which was developed by doctors at Cincinnati Children’s and the University of North Carolina. It can be particularly useful when access to allergy specialists is limited. Once you complete the simple online assessment, you will receive a personalized risk certificate to share with your child’s primary care and allergy doctors. You will then be guided through the next steps necessary for removing or testing a penicillin allergy label. 
  • E-Consults (For Physicians): E-Consults allow providers to digitally submit consultation requests to the Pediatric Antibiotic Allergy Test Service (PATS) team. PATS providers review the patient’s medical history, offer expert recommendations and next steps, and may provide reassurance in removing allergy labels to support safe reintroduction of medications.

After Your Appointment

When testing is complete, we will:

  • Explain results in clear, simple terms
  • Update your child’s medical record
  • Provide written guidance for future antibiotic use
  • Share findings with your child’s primary care provider and specialists
  • Provide wrap-around support and 24/7 contact information so the family can reach us with any questions or concerns

Our goal is to give families clarity, confidence, and peace of mind—so children can get the right medicine, at the right time, as safely as possible.

Frequently Asked Questions

Medication allergy testing helps determine if you’re truly allergic to a medication. Knowing this prevents unnecessary avoidance of important treatments and ensures you receive the safest, most effective care. Most allergy labels remain unchallenged and can persist into adulthood, restricting future treatment options and complicating care for decades.  
If you are experiencing allergic symptoms such as hives, rash, itching, swelling, our team is here to help. We offer same-day or next-day appointments, often via telehealth, to help manage your symptoms and provide prompt treatment.
  • Oral drug challenge: This is the most common testing method. Patients receive a weight- or age-based dose of the medication by mouth, followed by one hour of monitoring.  
  • Skin-prick test: A small amount of the medication is placed on the skin and pricked if indicated based on the medications' needs tested. 
  • Intradermal test: A small amount of the medication is injected under the skin for a more sensitive check.  
Yes, testing is done in a controlled setting. Emergency medications and equipment are always available in case of a reaction.
We see all ages from birth to 25 years.
Medication challenges usually take about 90-120 minutes, depending on the medication and your response during monitoring. 
Yes, certain medications, especially antihistamines like Zyrtec or Claritin, can affect your test results. Before your appointment, you’ll receive a detailed list of which medications to take and how long.
Your allergist will go over your results with you and explain what they mean. You’ll also receive clear guidance on next steps, such as which medications are safe, precautions to follow, and how to contact our office if you have concerns.
Yes, depending on your medical history, the allergy provider may recommend an at-home challenge. This will include a telemedicine visit or consult visit in clinic with the allergist, taking a dose of the medication at home, and then completing an E-Visit through MyChart to share the results and next steps.
Yes, with the free virtual risk assessment called Penicillin Allergy Decision and Mobile Empowerment, you’ll receive a personalized risk certificate that you can share with your primary care and allergy providers.
Not always. Hives during a suspected reaction does not automatically mean your child is allergic. Many children develop hives or rashes for many different reasons.  
If the reaction occurred later during treatment, it does not make an allergy more likely. A single dose of the medication helps us confirm that no immediate or severe reactions occur. Those who are truly allergic only need one dose to “remember” they are allergic.
No, a family history of medication allergies does not increase your child’s likelihood of being allergic. We still encourage testing for anyone with concerns, adults included. If your child hasn’t taken a medication solely because of family history, it is safe to start it without prior testing. However, we can schedule an appointment if caregivers prefer their child to be monitored during the first dose.
Treatment costs are determined by your child’s individualized care plan and insurance coverage. Our goal is to make high-quality care as affordable as possible.
