Got my first chemotherapy yesterday, now I look all red in the face. Anyone who knows why

Facial Flushing After Chemotherapy

Facial redness and flushing after chemotherapy is actually quite common, and there are several reasons this happens:

Most Common Causes:

1. Direct Drug Effect Some chemotherapy drugs cause blood vessels in your face and neck to dilate (widen), which increases blood flow to the skin and creates that red, flushed appearance. This is a known side effect of certain agents.

2. Allergic or Hypersensitivity Reaction Your body may be reacting to the chemotherapy drug itself or to additives in the IV solution. This can range from mild (just redness) to more significant reactions with itching, hives, or difficulty breathing.

3. Fever or Infection Response Sometimes the body's immune response to chemotherapy can trigger a mild fever, which causes flushing.

4. Medication Given During Treatment Drugs given alongside chemotherapy (like anti-nausea medications, steroids, or pre-medications) can also cause facial flushing as a side effect.

What You Should Do:

Contact your oncology team TODAY if you also have:

• Itching or hives
• Difficulty breathing or chest tightness
• Swelling of face, lips, or throat
• Fever (temperature over 100.4°F)
• Severe headache

Even if you only have redness, it's worth mentioning at your next appointment or calling your nurse line to report it. This helps your team:

• Understand how you're responding to this specific drug
• Adjust pre-medications for your next treatment if needed
• Rule out any concerning reactions

According to ASCO (American Society of Clinical Oncology) guidelines, monitoring and reporting side effects after each treatment is an important part of your care plan.
