What should I bring to my first allergist appointment?

Bring a symptom log if you have one, a list of all current medications including supplements and over-the-counter antihistamines, any previous allergy test results or medical records, your insurance card and referral documentation if required, and a written list of questions for your allergist. If you're bringing a child, include any notes from their school or childcare provider about reactions they've observed.

What happens during allergy testing at an allergist appointment?

There are two common types of allergy testing. Skin prick testing involves placing small amounts of common allergens on the surface of your skin and making a tiny scratch. A small raised bump appears within 15 to 20 minutes if you're allergic. Blood testing, also called specific IgE testing, measures your immune response through a blood draw and is often used when skin testing isn't appropriate. Your allergist will recommend the approach that makes the most sense for your situation.

Should I stop taking antihistamines before my allergist appointment?

Many antihistamines can interfere with skin prick testing results. Your allergist's office will typically tell you how many days before the appointment to stop taking them. Follow that guidance carefully, and contact the office if you're unsure.

What comes after a first allergist appointment?

A first allergist appointment is the beginning of a process, not a one-visit solution. Next steps might include a follow-up appointment to review results and build a management plan, a referral for additional testing, a prescription for a new medication or epinephrine auto-injector, guidance on allergen avoidance strategies, or a conversation about immunotherapy — a treatment that gradually trains your immune system to become less reactive to a specific allergen.

What to Expect at Your First Allergist Appointment

Starting something new in your healthcare journey can feel like a lot — especially when allergies have already been taking up so much space in your life. Maybe you've been dealing with symptoms for months. Maybe your child just had a reaction that scared you. Maybe you finally pushed through the waiting list and the appointment is next week, and now you're not sure what's actually going to happen when you walk through that door.

That uncertainty is completely normal. And this page is here to take care of it.

Here's what a first allergist appointment typically looks like, what to bring, and how to make the most of your time with your new care team.

Before You Go: What to Bring and Why It Matters

A little preparation goes a long way. Allergists — physicians who specialize in diagnosing and treating allergic conditions — work best when they have the full picture. The more context you can give them, the faster you'll get to answers.

Here's what to pull together before your appointment:

A symptom log, if you have one. Even rough notes help. When do symptoms happen? What were you doing, eating, or near when they started? Any patterns you've noticed — seasonal, environmental, food-related — are worth mentioning.
A list of all current medications. Include everything: prescriptions, over-the-counter antihistamines, supplements, and any creams or nasal sprays you've been using. Your allergist needs to know what's already in your routine.
Your medical history and any previous test results. If you've had allergy testing before, bring those records. Same goes for relevant lab work, specialist notes, or a summary from your primary care physician.
Your insurance card and any referral documentation. Administrative, yes — but worth confirming ahead of time so it doesn't eat into your appointment.
A list of questions. This one matters more than people think. It's easy to go blank the moment you're sitting in the exam room. Write your questions down beforehand so you don't leave wishing you'd asked something.

If you're bringing a child to their first appointment, include any notes from their school or childcare provider about reactions they've observed. Teachers and caregivers often notice things that happen outside the home — and that information can be genuinely useful.

What Happens During the Appointment

Most first appointments with allergists follow a similar structure. Knowing what's coming makes it easier to stay present and get the most out of the visit.

A detailed health history

According to the American College of Allergy, Asthma & Immunology (ACAAI), your allergist will ask about your symptoms — when they occur, how often, and what seems to bring them on. They'll also ask about your work, home, and eating habits. This isn't small talk. It's the foundation of your care. Be as specific as you can, and don't downplay anything. Even symptoms that seem minor or unrelated may be relevant.

A physical exam

Your allergist may examine your skin, nasal passages, eyes, and lungs. For children, this part of the visit tends to be quick and straightforward.

Allergy testing — at this visit or scheduled separately

The ACAAI notes that skin testing is the preferred method used by trained allergists and is usually the most accurate. There are two common types:

Skin prick testing involves placing a small drop of a possible allergen on the surface of your skin — usually on the forearm for adults and on the back for children — and making a tiny prick. According to the ACAAI, if you're allergic to a substance, a small raised bump similar to a mosquito bite appears at that spot within about 15 minutes. It's not painful for most people, though it can be a little itchy.
Blood testing — sometimes called specific IgE testing, where IgE refers to immunoglobulin E, the antibody your immune system produces in response to allergens — measures your immune response through a blood draw. The ACAAI explains that this option is often used when skin testing isn't appropriate, such as for people with certain skin conditions or those who cannot stop their medications before the visit.

Your allergist will recommend the approach that makes the most sense for your situation.

Important note on antihistamines: The ACAAI advises stopping antihistamines 3 to 7 days before allergy skin testing, as they can interfere with test results. Your allergist's office will tell you exactly how many days in advance — follow that guidance carefully, and ask if you're unsure.

Questions Worth Asking Before You Leave

Your allergist's time is limited, and so is yours. These questions can help you leave with a clearer picture of where things stand:

What do these results mean for my daily life?
Are there environmental changes I should make at home?
What should I do if I have a reaction before my next appointment?
Should I be carrying an epinephrine auto-injector — a device that delivers a fast dose of epinephrine to slow a severe allergic reaction?
What does a longer-term management plan look like for my situation?

You don't have to ask all of them. But having them written down means you won't walk out the door wondering.

What Comes After the Appointment

A first allergist appointment is the beginning of a process, not a one-visit solution. Depending on what your allergist finds, next steps might include:

A follow-up appointment to review test results and build a management plan
A referral for additional testing
A prescription for a new medication or an epinephrine auto-injector
Guidance on allergen avoidance strategies for your home or workplace
A conversation about immunotherapy — a treatment that gradually trains your immune system to become less reactive to a specific allergen — if it's appropriate for your situation

Whatever comes next, you'll have a real starting point. That's what this first appointment is really for.

Frequently Asked Question

Do I need a referral to see an allergist?

It depends on your insurance plan. Many plans require a referral from your primary care physician before covering a specialist visit — but some allow you to self-refer. Check with your insurance provider before scheduling. You can also use the AAAAI's Find an Allergist tool to locate a board-certified allergist in your area.
