What to Expect at Your First Chemotherapy Infusion | Megha Shah, DNP, FNP, OCN

Getting ready for your first chemotherapy infusion is one of the most anxiety-provoking moments in a cancer diagnosis. Patients tell me this all the time. The fear is rarely about the treatment itself — it is about not knowing what is going to happen when they walk through those doors.

I work as a nurse practitioner at an outpatient oncology infusion center, and I have walked hundreds of patients through their first treatment. What I have learned is that the unknown is almost always worse than the reality. When people understand what to expect, the appointment gets a little less frightening. This guide walks you through the full experience, step by step.

What to Bring to Your First Chemo Appointment

Before we get into what happens during the visit, let’s talk about what to bring. Being prepared makes a real difference.

Bring a support person. Most infusion centers allow one family member or friend in the treatment bay with you. Having someone there to take notes, ask questions, and sit with you during a longer infusion matters. You should not plan to drive yourself home after your first treatment — some pre-medications cause drowsiness, and you may not know yet how your body will respond to the drugs.

Bring something to keep yourself occupied. Infusions can last anywhere from 30 minutes to several hours depending on your regimen. Books, headphones, a tablet, knitting — anything that helps you feel comfortable and relaxed. Many centers have blankets and pillows available but calling ahead to confirm never hurts.

Bring a list of your current medications. This includes over-the-counter drugs, vitamins, and supplements. Your care team will review this before your infusion. Some supplements, including certain herbal products, can interact with chemotherapy.

Bring your questions written down. You will have more questions than you think, and nerves have a way of making them disappear. Write them down in advance.

What Happens During Your First Chemo Appointment

Step 1: Check-in and registration

You will check in at the front desk, and a nurse or medical assistant will bring you back to complete your vital signs — blood pressure, heart rate, temperature, weight, and oxygen saturation. Your weight matters for chemotherapy dosing, which is why it is taken at nearly every visit.

Step 2: Lab work and pre-treatment assessment

Before any chemotherapy can be given, your care team needs to confirm your labs look safe for treatment. Most patients have blood drawn — either from a peripheral vein or from a port if one has been placed. The most important values are your white blood cell count, neutrophil count, platelet count, and kidney function. Low counts can mean your treatment needs to be held or dose-adjusted. This is not unusual, and it is not a sign that your cancer is progressing. It is your care team keeping you safe.

A nurse or provider will also review how you have been feeling since your last visit or since your diagnosis. Tell them honestly about any symptoms — fatigue, pain, nausea, changes in appetite, constipation, or anything else you have noticed. Nothing is too small to mention.

Step 3: IV access or port access

If you have a port — a small implanted device that allows IV access without repeated needle sticks — a nurse will access it with a special needle. This takes about a minute and may feel like a small pinch. If you do not yet have a port, an IV will be placed in a vein in your arm or hand. For patients who will be receiving chemotherapy long-term, a port often makes the experience much more comfortable, and your team may recommend one.

Step 4: Pre-medications

Most chemotherapy regimens come with pre-medications given before the actual treatment begins. These may include anti-nausea medications such as ondansetron, steroids to prevent allergic reactions, antihistamines like diphenhydramine, and fluids for hydration. Some pre-medications cause sleepiness, which is completely expected. This is a good time to get settled with your blanket, put on some music, and relax.

Step 5: Chemotherapy administration

Once your labs are confirmed and your pre-medications are on board, the chemotherapy will be started. The nurse will begin the infusion slowly and stay nearby, especially at the start, to watch for any reactions. Signs of an infusion reaction can include flushing, itching, chest tightness, or shortness of breath. These reactions are not common, but when they happen, your nurse will respond quickly — stopping the infusion, assessing you, and calling the provider.

The infusion itself may feel like nothing at all. Some patients fall asleep. Some chat with the person who came with them. Some watch a movie. The drugs are going in through your IV line, and you generally cannot feel them.

Step 6: End of infusion and discharge

When your treatment is complete, the nurse will flush your IV line or de-access your port and review discharge instructions with you. This is the time to go over what side effects to watch for at home, what medications to take, when to call the clinic, and when your next appointment is scheduled. Ask about the 24-hour nurse line if you are not sure how to reach someone after hours.

What to Wear

Wear loose, comfortable clothing that gives easy access to your arms. If you have a port in your chest, a top with a loose neckline or a button-front shirt makes port access easier. Layers are a good idea — infusion centers can feel cold.

Leave your jewelry at home. Skip strong fragrances. Some patients undergoing treatment are sensitive to smells, and common courtesy goes a long way in a shared space.

How Long Does the First Appointment Take?

Plan for the first appointment to take longer than subsequent visits. You will have more labs reviewed, more teaching to complete, and possibly more conversations with your provider. Some first infusions take three to four hours even if the actual drug administration time is shorter. Build in that time and do not schedule anything demanding immediately after.

Questions to Ask at Your First Infusion

Write these down and bring them:

• What side effects should I watch for in the first 24 to 48 hours?
• When do I call the clinic, and when do I go to the emergency room?
• Are there any foods, drinks, or supplements I should avoid during treatment?
• How will we know if the treatment is working?
• What do I do if I miss a dose of my take-home medications?
• Who do I call after hours if I have a problem?

Frequently Asked Questions

Will I feel sick during the infusion? Most patients do not feel acutely ill during the infusion itself. Nausea is more common in the hours to days after treatment. Your care team will send you home with anti-nausea medications and specific instructions for when to take them.

Can I eat before my infusion? In most cases, yes. Arriving hydrated and having a light meal beforehand is actually a good idea. Your nurse will confirm any specific preparation instructions when you schedule your appointment.

What if I need to use the bathroom? You can. The IV tubing connects to a wheeled pole, and most patients can walk to the restroom while their infusion is running. Just let your nurse know.

Will I lose my hair? That depends on the specific chemotherapy regimen. Some drugs cause hair loss, and some do not. Your oncology provider will tell you what to expect from your particular treatment plan.

Can I be alone at the infusion center? Yes, many patients come alone to follow-up treatments once they are comfortable with the process. For your first appointment, I always recommend having someone with you.

The first chemotherapy infusion appointment is hard to walk into without nerves. But it is also full of people whose entire job is to take care of you. The nurses in an infusion center see patients on some of the most difficult days of their lives, and most of them chose this work because they genuinely want to be there. You are not going to be walking into that room alone.
