🧭 Life‑Threatening Red Flags
Call now
🌡️ Fever ≥ 38°C
- On treatment, fever = medical emergency.
- Do not mask with antipyretics unless instructed.
- Chills/shivering → consider neutropenic sepsis.
Urgent
🩸 Bleeding
- Not stopping after 10 min pressure.
- Black/tarry stool or coffee‑ground vomit → GI bleed.
- Heavy urine/vaginal bleeding.
ER
🫁 Dyspnea / Chest Pain
- Clot risk ↑ 4–7×; DVT/PE ~20%.
- Sharp chest pain, hemoptysis, rapid worsening.
🧠 Severe / Worsening Pain
- Thunderclap headache, crushing back pain, knife‑like abdomen.
- Neurologic signs (weakness, slurred speech, confusion).
🧪 Confusion, Extreme Lethargy
- Infection, metabolic issues, or IO endocrine crisis possible.
- Severe pallor/breathlessness at rest → assess for anemia.
🚰 Persistent Vomiting / Diarrhea
- ≥3 severe vomits/24h or unable to keep fluids.
- ≥4 watery stools/day or blood/mucus.
🛎️ Urgent Adverse Effects Requiring Action
🦠 Infection (even without fever)
- Chills/sweats, productive cough, sore throat, dental abscess.
- Dysuria; redness/discharge at catheter site.
- Why urgent? May evolve to sepsis within hours.
🤢 Refractory Nausea/Vomiting
- Fails prescribed antiemetics → dehydration/electrolyte loss.
- Small sips; IV fluids if unable to drink.
🚰 Persistent Diarrhea
- With IO, suspect immune colitis → early steroids.
- Use loperamide if advised; escalate if no improvement in 24h.
🗣️ Severe Mucositis / Dysphagia
- Blocks oral intake → IV fluids, topical analgesics, mouthwashes.
- Cold/soft foods; salt‑bicarbonate rinses; soft toothbrush.
🧴 Extensive Rash / Blisters
- Widespread rash, bullae, skin peeling (SJS/TEN) = ER.
- Anaphylaxis: hives, lip swelling, throat tightness, dyspnea → 112.
🛡️ Immune‑Related Toxicities (IO)
- Lungs: dry cough, dyspnea → pneumonitis.
- Liver: jaundice, dark urine → hepatitis.
- Endocrine: severe fatigue, dizziness, low BP → adrenal/thyroid/pituitary.
🧩 Home First Aid & Monitoring
🌡️ Track Temperature
- Working thermometer accessible.
- ≥38°C → call.
- Don’t mask fever without advice.
☎️ Contacts & Plan
- Store 24/7 numbers (phone/fridge/wallet).
- Plan: “If fever → call X; if unreachable → ER at Y.”
🧼 Infection Prevention
- Frequent proper handwashing; avoid crowds in outbreaks.
- Food safety: avoid raw meats; wash produce well.
🧷 Catheter & Wound Care
- Daily check for redness/swelling/heat/discharge.
- Timely dressing changes; clean technique.
🩸 Bleeding – First Aid
- Nosebleed: sit, lean forward, pinch 10 min.
- External wounds: direct pressure; elevate.
🥤 Fluids & Nutrition
- Goal: ≥8 cups/day; no urine in a day → urgent call.
- Small sips; oral rehydration during vomiting/diarrhea.
🗓️ Symptom & Drug Log
- Note cycles; neutropenia often day 7–14.
- Track measurable events (e.g., “Mon 2× vomit; Tue 0×”).
🧠 Stay Calm & Supported
- Simple step order to reduce panic.
- Share feelings with the team; consider psychological support.
🧠 Common Pitfalls → Evidence‑Based Actions
🌡️ “I’ll wait; fever might go down.”
- Wrong: Waiting, cold showers, random antipyretics.
- Right: Measure now; if ≥38°C → call immediately.
🗣️ Hiding Symptoms
- Wrong: Not reporting recurrent vomiting/diarrhea/cough.
- Right: Report any new symptom early.
📞 “I shouldn’t bother my doctor.”
- Wrong: Waiting overnight/weekend.
- Right: Call; if unreachable, go to the ER.
💊 Self‑medicating
- Wrong: Starting steroids/antibiotics/supplements on your own.
- Right: Use back‑up meds as prescribed; don’t up‑dose — call.
🧭 Going to the Wrong Place
- Wrong: Small clinic/pharmacy for neutropenic patient.
- Right: Prefer your center or a major hospital ER; ask for oncology liaison if possible.
🧠 Fatigue → Neglect
- Wrong: Dropping precautions out of exhaustion.
- Right: Keep simple routines; share responsibilities; seek support.
