The short answer
Your first chemotherapy infusion day involves check-in, blood draws to verify blood counts, pre-infusion medicines to prevent nausea and allergic reactions, the chemotherapy infusion itself, and a review of home care instructions before leaving.
First infusion days take longer (often 4 to 6 hours) due to pre-meds and safety monitoring.
Pre-medications (anti-nausea drugs and steroids) are given before chemotherapy begins.
Infusion suites are designed for comfort with reclining chairs, blankets, and space for a support person.

Immediate Answer
Your first chemotherapy infusion day usually takes longer than subsequent visits (often 4 to 6 hours). The day follows a clear sequence: clinic check-in, blood draws to confirm your blood counts are safe, pre-medications to prevent nausea and reactions, the chemotherapy infusion itself, a short monitoring period, and a review of your home prescription instructions.
Chemo Day Timeline
[ Check-in & Vitals ] ➔ [ Blood Lab Work ] ➔ [ Pre-medications ] ➔ [ Chemo Infusion ] ➔ [ Home Instructions ]
1. Check-In & Blood Work (1 Hour)
Upon arrival at the infusion center, a nurse will check your vital signs (blood pressure, temperature, heart rate, weight). Blood is drawn from your arm vein or chemo port to verify that your white blood cells, platelets, and organ function are safe for treatment.
2. Provider Check & Orders Released
Once lab results return, your oncologist or nurse practitioner approves your individualized chemotherapy dose. The hospital pharmacy then mixes your medicines.
3. Pre-Medications (30–60 Minutes)
Before chemotherapy starts, you receive intravenous or oral premedications. These typically include:
- Anti-nausea drugs (such as ondansetron or palonosetron).
- Steroids (such as dexamethasone) to reduce inflammation and prevent allergic reactions.
- Antihistamines (such as diphenhydramine) if required for specific drugs.
4. Chemotherapy Infusion (1–4 Hours)
Chemotherapy is infused slowly through an IV line or port. Infusion suites feature comfortable reclining chairs, heated blankets, and space for a support companion. You can read, sleep, listen to music, or watch videos.
5. Discharge & Home Care Review
Before you leave, your nurse will review your prescription anti-nausea medication schedule, hydration goals, and emergency phone numbers.
4 Essential Safety Tips for First Infusion Day
- Report Any IV Discomfort: If you feel burning, stinging, tightness, or swelling near your IV or port, tell your nurse instantly.
- Stay Hydrated: Drink plenty of water before and after your infusion to help your kidneys flush out treatment byproducts.
- Take Pre-Emptive Anti-Nausea Pills: Take your prescribed home anti-nausea pills on schedule, even if you feel fine initially.
- Have a Driver: You may feel drowsy from premedications (like Benadryl), so arrange for someone to drive you home.

No. Intravenous chemotherapy should not burn or hurt. If you feel sting, burning, or swelling near your IV site or port, notify your infusion nurse immediately, as the IV may need adjusting.

Most infusion centers allow one support person to sit with you during treatment. Check your clinic's visitor policy beforehand.
