What Caregivers Should Know About Chemotherapy

## Your Role Is Critical Caregivers are not just emotional support — they are active participants in cancer treatment. Studies show that patients with engaged caregivers have better treatment adherence, fewer hospitalizations, and better outcomes. You don't need a medical background. You need to be informed, observant, and willing to ask questions. ## The Most Important Thing to Know: The Fever Rule **A temperature of 100.4°F (38°C) or higher in someone on chemotherapy is a medical emergency.** This is because chemotherapy lowers white blood cell counts, particularly neutrophils — the cells that fight bacterial infections. A patient on chemo with a fever may have **febrile neutropenia**, which can progress to sepsis rapidly. **Do not wait and see. Do not give Tylenol and recheck in an hour. Call the oncology team immediately or take them to the ER.** Keep a thermometer at home. Take the temperature any time they seem unwell, feel hot, or have chills. ## Key Warning Signs — Call Immediately - Fever ≥ 100.4°F - Severe vomiting, can't keep fluids down for 24 hours - Signs of dehydration (dark urine, dizziness, extreme dry mouth) - Unusual bruising or bleeding - Shortness of breath or chest pain - Confusion, change in mental status - Severe pain ## Know the Treatment Schedule Understand the basics of your loved one's regimen: - What drug(s) are they receiving? - When is infusion day? - When is the nadir (lowest blood count period)? Usually days 7–14 after infusion. - When do labs need to be drawn? - What anti-nausea medications are prescribed and when should they be taken? Write this down. Keep it somewhere accessible. ## Day-of-Infusion Responsibilities - Drive them to and from the infusion center (they should not drive) - Bring snacks, a blanket, entertainment - Take notes during any discussions with the nurse or oncologist - Observe how they react during infusion — report anything unusual to the nurse ## Post-Infusion Days (Days 1–3) - Make sure they take anti-nausea medications on schedule, even if they feel okay - Prepare bland, easy foods in advance - Encourage fluids constantly - Watch for fever obsessively during the nadir ## Protecting Them From Infection During low white count periods: - Wash hands frequently - Don't bring sick visitors around - Avoid crowded public places when counts are lowest - Handle raw meat carefully; well-cooked foods only - Ask the oncology team if any specific precautions apply ## Managing Medications at Home - Keep a current, accurate medication list - Know which anti-nausea medications are "as needed" vs. scheduled - Understand any interactions (ask the pharmacist) - Help them stay on schedule — set alarms if needed ## Take Care of Yourself Caregiver burnout is real and will compromise the care you can provide. Accept help when offered. Maintain at least one activity outside of caregiving. Seek support from other caregivers or a counselor.
