Management Strategies for EGFR TKI Adverse Effects: Summary for Physicians
Dermatologic Toxicity Management
- Proactive skin care regimen before initiating EGFR TKIs:
- Recommend non–alcohol-based creamy moisturizers (morning and night)
- Daily SPF 30+ sunscreen on exposed areas
- Encourage protective clothing (hats, long sleeves)
- Treatment options for acneiform rash:
- Topical steroids
- Oral doxycycline (helps reduce severity and prevent superimposed infection)
- Consider dermatology referral for severe cases
Diarrhea Management
- Patient education:
- Instruct patients to monitor and track stool frequency above baseline
- Emphasize adequate hydration
- Dietary modifications:
- Recommend BRAT-style diet (bananas, rice, apples, toast)
- Avoid dairy, greasy, and fatty foods
- Pharmacologic intervention:
- Provide step-by-step loperamide (Imodium) dosing instructions
- Review medication list for potential exacerbating agents
- Instruct patients to hold laxatives/stool softeners during diarrhea episodes
Clinical Pearls
- Male patients may require additional encouragement regarding skin care regimens
- Emphasize importance of patient communication between visits
- Always perform medication reconciliation to identify potential contributory medications
- Ensure patients have clear instructions for all prescribed treatments
This approach focuses on proactive management to minimize adverse events while maintaining treatment efficacy.
