After surgery for colon cancer, many people diagnosed with stage III disease are advised to begin adjuvant chemotherapy, and a common first question is what to pack for the initial infusion. Hot packs, gloves and warm drinks appear on many lists for a specific reason: several chemotherapy combinations used for stage III colon cancer include a drug called oxaliplatin, which often makes the body unusually sensitive to cold for the first few days after treatment.
This effect is called acute cold hypersensitivity. Drinking something cold can feel like a tightening in the throat, touching a cold cup or a metal door handle can send a pins-and-needles jolt through the fingertips, and cold air on the face or hands can trigger tingling. It is not a sign of permanent nerve damage. Instead, the medicine briefly makes nerve signalling more excitable, and the sensation usually stands out in the first days after an infusion and then settles.
That is why hot packs, gloves, a scarf and room-temperature or warm water can help. During the infusion and for a few days afterward, it is easier to sip water that is at room temperature or warmer, and to avoid handling ice, food straight from the fridge or cold metal surfaces with bare hands. These steps ease the discomfort rather than changing how the drug works.
This short-lived reaction is different from the chronic peripheral neuropathy (CIPN) that can build up slowly in the hands and feet over several cycles. The acute symptoms tend to ease within days, but numbness that keeps worsening — enough to make buttoning a shirt difficult — is worth reporting at every visit, because dose and timing are often adjusted based on these signals.
A caregiver also has a role during the infusion itself. Oxaliplatin and other chemotherapy drugs can, uncommonly, cause an infusion reaction during or shortly after treatment: flushing, itching, hives, chest tightness, shortness of breath, back pain or chills. If any of these appear, it is important to tell a nurse right away rather than waiting. A caregiver can keep the patient warm and note when a symptom started and how long it lasted, which helps the medical team decide what to do.
Whether to stay near the hospital or recover at home after the first cycle depends on personal circumstances, and there is no single right answer. What matters most is deciding in advance where to call and where to go if a fever develops (especially 38°C or higher), if severe diarrhoea or vomiting makes it hard to keep fluids down, or if breathing or pain becomes hard to manage. Writing down the treating hospital's after-hours contact and the nearest emergency room helps avoid scrambling in a crisis.
