Chemotherapy Side Effects
A complete, practical guide to chemotherapy side effects — what is expected, what is an emergency, and how to cope at home — written with Indian food, Indian homes, and Indian families in mind.
Starting chemotherapy is one of the most anxious moments for any patient and family. The fear is often not of the cancer — it is of the treatment. What will happen to my body? Will I be able to eat? Will I lose my hair? What if I get a fever at 2am?
These are the questions every patient asks. This guide answers them — with Indian food, Indian homes, and Indian families in mind.
What most patients want to know before they start
- Side effects vary by drug — not every patient gets every side effect.
- Most side effects are temporary and resolve after treatment ends.
- Days 7–14 of each 3-weekly cycle are your highest-risk days for infection.
- Fever above 100.4°F (38°C) during chemo is a medical emergency — call immediately.
- Indian home cooking — freshly made rice, dal, khichdi — is ideal chemo food.
- Hair loss is almost always temporary — it grows back after treatment ends.
If you develop a fever above 100.4°F (38°C) at any point during chemotherapy — call your doctor immediately. Do not take paracetamol and wait. Do not wait until morning to see if it settles. Go to hospital and tell them: "I am a chemotherapy patient and I have a fever."

ReadWhy we created this resource
Cancer care does not end when you leave the clinic. Many of the most important questions arise later — after chemotherapy, while reading a blood report, or at 2am when a new symptom appears. Too often, patients are left searching the internet, where accurate, practical information can be difficult to find.
We created this resource to give patients and families clear, evidence-based guidance they can trust. Every article is written from the questions we hear every day in our clinic, with the aim of helping you feel informed, prepared, and a little less overwhelmed.
Whether you are receiving treatment with us or looking for an oncologist in Hyderabad, we hope these guides help you make informed decisions with confidence. If you have questions, our team is always happy to help — WhatsApp our patient coordinator: 7207815222.
