Your First Chemotherapy Cycle: — What Happens on the Day

Start with the essentials: your ID and any hospital documents, a list of medicines you currently take, and anything your centre asked you to bring. Beyond the paperwork, plan for a few hours of sitting still — a book, phone, or earphones helps. Some people bring a light blanket because units can feel cold. A small snack is usually fine, though ask your nurse whether your specific regimen requires you to eat or avoid eating beforehand.

Most day-care units allow one person to accompany you, at least for part of the session. Check your centre's policy when you confirm your appointment — space is sometimes limited during busy periods. Many people find it reassuring to have someone with them for the first cycle, even if they come alone for later ones. If your companion is present, the nurse will usually explain the process to them as well.

Most people do not feel significantly unwell while the drip is running. The premedicines given at the start are intended to prevent nausea during the session. You might notice a mild metallic taste or feel slightly tired — both are common. Nausea and fatigue most commonly start in the hours after you get home, not in the unit. If anything does feel wrong while you are there, tell your nurse immediately — that is exactly why a nurse is with you throughout.

For most people and most regimens, a light meal before coming is sensible. Arriving on an empty stomach can make nausea harder to manage. Some regimens have specific instructions about eating or fasting — your nurse or oncologist will mention it at your pre-treatment appointment if yours does. If you have not received any specific advice, a light meal a couple of hours before is generally reasonable, but confirm at your appointment rather than assuming.

Allergic and infusion reactions can occur with some chemotherapy medicines, which is one of the reasons you are observed closely throughout — especially during the first session. If you feel warmth, flushing, itching, tightness in your chest, breathlessness, or a sudden feeling of panic, tell your nurse immediately without waiting to see if it passes. The infusion can be slowed or stopped, and medicines to manage a reaction are available in the unit. Being in a supervised setting is exactly the protection this creates.
