🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is an irreversible pan-HER tyrosine kinase inhibitor. It binds covalently to cysteine residues in the ATP-binding pocket of EGFR, HER2, and HER4, blocking their kinase activity. This prevents autophosphorylation and downstream signalling through pathways such as MAPK and PI3K/AKT, which are important for cancer cell growth, survival, and spread. Because the binding is irreversible, the inhibitory effect lasts longer than that of reversible inhibitors. In tumours with activating EGFR mutations, this blockade leads to reduced proliferation and increased cell death. The same mechanism in normal tissues such as skin, gut, and eyes explains many of the side effects.

Avoid grapefruit and grapefruit juice during treatment. Use effective contraception during treatment and for at least two weeks after the last dose if you are of childbearing potential, and do not breastfeed while taking this medicine. Keep all scheduled blood tests, eye checks, and heart scans because early detection of problems allows safer treatment.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Older adults may be more sensitive to the side effects of this medicine, especially diarrhoea, dehydration, skin rash, and fatigue. They may also have other health conditions and take multiple medicines, which increases the risk of interactions. Your doctor may start at a lower dose and monitor you more closely. Regular checks of liver, kidney, and heart function are especially important.
🤰 Pregnancy Planning (TTC)
This medicine can harm a developing baby. Women of childbearing potential must use effective contraception during treatment and for at least two weeks after the last dose. Men with female partners of childbearing potential should also use effective contraception during treatment and for at least two weeks after the last dose. If you are planning pregnancy, discuss it with your oncologist before starting or stopping this medicine.
🏥 Post-Surgery Considerations
If you are planning surgery, tell your surgeon and anaesthesiologist that you are taking this medicine. Your oncologist may advise you to stop it for a short period before and after surgery because of the risk of poor wound healing and interactions with anaesthetic medicines. Do not stop on your own; follow your specialist's instructions.
🦷 Dental Procedures
Tell your dentist that you are taking this medicine before any dental procedure. This medicine can cause mouth sores and increase the risk of bleeding or infection. Your dentist may recommend delaying non-urgent procedures until your blood counts and general condition are stable. Maintain good oral hygiene and use a soft toothbrush to reduce mouth irritation.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
You can continue gentle exercise such as walking or light yoga if you feel well, but avoid strenuous activity if you have diarrhoea, dizziness, or fatigue. If you have heart problems or develop swelling in your legs, ask your doctor before starting any exercise programme. Always warm up and stop if you feel breathless, dizzy, or unwell.
🥗 Diet Recommendations
💼 Impact on Daily Work & Life
This medicine can cause fatigue, diarrhoea, and eye problems, which may affect your ability to drive or operate heavy machinery. Avoid driving if you feel dizzy, tired, or have blurred vision. Most patients can continue desk work, but you may need flexible hours during the first few weeks of treatment. Talk to your employer about your treatment schedule and possible need for rest days.
🛑 When to Stop This Medicine
Do not stop this medicine on your own. Your oncologist will decide when to stop based on tumour response, side effects, and your overall health. If you develop a serious side effect such as interstitial lung disease, severe liver injury, or a severe skin reaction, your doctor may tell you to stop temporarily or permanently. Always contact your doctor before stopping.
📅 Long-Term Use Effects
Long-term use of this medicine may lead to persistent skin changes, chronic diarrhoea, nail problems, and eye dryness. Regular monitoring of liver, kidney, and heart function is required. Some patients may develop resistance to the medicine over time, which means the cancer may start growing again. Your oncologist will assess response with regular scans and adjust treatment if needed. Long-term effects on fertility are not fully established, so discuss family planning with your doctor before starting treatment.
🌿 Non-Medicine Approaches
These can complement medicine but do not replace prescribed treatment.
Medicines such as erlotinib, gefitinib, or osimertinib may be options depending on the specific EGFR mutation and prior treatments.
Evidence: Well-establishedPlatinum-based chemotherapy may be used alone or in combination with other medicines, depending on the cancer type and stage.
Evidence: Well-establishedIn some lung cancers without EGFR mutations, immunotherapy may be an option, but it is generally not used first in EGFR-mutant cancers.
Evidence: Established for selected patientsNew targeted therapies and combinations are being studied in clinical trials for advanced lung cancer.
Evidence: Variable💉 Vaccination Considerations
💉 If You're Getting Vaccinated
Talk to your oncologist before receiving any vaccine. Live vaccines should generally be avoided during treatment because the immune system may be weakened. Inactivated vaccines, such as the flu vaccine, may be recommended, but timing should be discussed with your doctor.
