Chemotherapy Drugs 🧪
Quick reference for common chemotherapy drugs: classes, dosing, side effects, and monitoring requirements for NCHDs.
⚠️ Important Safety Notes
- Chemotherapy handling requires specialized training and PPE - never handle without proper training
- Always follow local oncology protocols and consult with oncology team before any administration
- Many drugs are vesicants (cause tissue damage) - extravasation protocols must be followed
- Monitor for hypersensitivity reactions - have emergency equipment ready
- Check renal/hepatic function before administration of most agents
Common Side Effects & Management
- Nausea/Vomiting: 5-HT3 antagonists (ondansetron), NK1 antagonists (aprepitant), steroids
- Myelosuppression: Monitor FBC, consider G-CSF, blood transfusions if needed
- Mucositis: Good oral hygiene, mouthwashes, pain management, nutritional support
- Diarrhea: Loperamide, fluid replacement, consider dose reduction
- Hand-foot syndrome: Emollients, avoid friction, consider dose reduction
- Neuropathy: Gabapentin/pregabalin, dose modification, physiotherapy
- Alopecia: Scalp cooling, wigs, psychological support
Emergency Situations
- Extravasation: Stop infusion immediately, aspirate, apply cold/heat as per protocol, notify oncology
- Hypersensitivity: Stop infusion, give antihistamines/steroids, consider adrenaline if severe
- Tumor lysis syndrome: IV fluids, allopurinol, rasburicase, monitor U&E closely
- Febrile neutropenia: Immediate antibiotics, consider G-CSF, hospital admission
- Cardiotoxicity: Stop anthracyclines, cardiology review, consider dexrazoxane
Pre-treatment Assessment
- Full blood count (FBC) - check for adequate counts
- Renal function (U&E, eGFR) - many drugs require dose adjustment
- Liver function (LFTs) - hepatotoxicity risk
- Cardiac function (echo) - for anthracyclines and trastuzumab
- Pregnancy test - if applicable
- Performance status assessment
- Baseline neurological assessment for neurotoxic drugs
