Gefitinib (250mg).
Jun 13, 2023
The drug gefitinib 250 mg belongs to a special category of anticancer drugs known as tyrosine kinase inhibitors (TKIs). It differs from the classical chemotherapy which targets any rapidly growing cells in the body because it targets cancer cells containing EGFR gene mutation.
GEFISTERIS 250 contains gefitinib 250 mg as its main drug ingredient. This makes the drug effective against cancer because the mechanism of action is specific targeting of pathways involved in signaling for tumor cell growth and proliferation hence preventing them from obtaining the growth factors required for survival.
This drug, gefitinib, comes in the form of a tablet which can be taken orally, unlike the classical chemotherapy treatment which involves an intravenous route.
What is Gefitinib 250 mg Used For?
Primary Indication
Tab gefitinib 250 mg is primarily prescribed for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) in patients whose tumors have specific EGFR mutations. These mutations are detected through genetic testing of tumor tissue or blood samples.
Specific Uses Include:
- First-line treatment for EGFR mutation-positive NSCLC
- Treatment of patients who have received previous chemotherapy
- Management of advanced lung cancer that has spread to other parts of the body
- Maintenance therapy after initial response to treatment
Tab gefitinib 250 mg uses are specifically limited to patients with confirmed EGFR mutations, which is why genetic testing is essential before starting treatment.
Is Gefitinib a Chemotherapy?
This is a common question, and the answer is nuanced. Gefitinib is not traditional chemotherapy . Instead, it's classified as a targeted therapy or biological therapy .
Gefitinib works only in patients whose tumors carry specific EGFR mutations, making genetic testing essential before treatment.Because it is a targeted therapy, Gefitinib is often associated with fewer severe side effects than conventional chemotherapy.
Key Differences:
Traditional Chemotherapy: - Attacks all rapidly dividing cells (both cancerous and healthy)
- Often causes severe side effects like hair loss and severe nausea
- Given in cycles with rest periods
Gefitinib (Targeted Therapy): - Specifically targets cancer cells with EGFR mutations - Generally has fewer and less severe side effects
- Taken continuously as a daily oral tablet
While both are cancer treatments, gefitinib's targeted approach typically results in better tolerability and quality of life for patients.

Frequently Asked Questions (FAQ)
1. Does Gefitinib 250 mg require a prescription?
Yes. Gefitinib is a specialized targeted cancer medication. It must only be taken under the direct supervision of an oncologist who has confirmed your EGFR mutation status through genetic testing. Never attempt to purchase or take this medication without a valid prescription.
2. Can I take GEFISTERIS 250 if I don't have an EGFR mutation?
No. Gefitinib is specifically designed to target the EGFR protein. Clinical studies show that it is significantly less effective in patients who do not have these specific mutations. Your oncologist will perform a biopsy or liquid biopsy to determine if you are a candidate for this therapy.
3. What should I do if I miss a dose of Gefitinib?
If you miss a dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed one entirely. Do not take two tablets at once to make up for a missed dose, as this increases the risk of side effects.
4. How long does it take for Gefitinib to start working?
Many patients begin to notice improvements in symptoms like coughing or shortness of breath within a few weeks of starting treatment. However, objective tumor shrinkage is typically confirmed during follow-up CT or PET scans, which are usually scheduled every 2 to 3 months.
5. Can I consume alcohol while on Gefitinib?
It is best to avoid or strictly limit alcohol while taking Gefitinib. Alcohol can put additional stress on the liver, and because Gefitinib can sometimes affect liver enzyme levels, combining the two may complicate monitoring your health. Always consult your doctor for specific advice based on your liver function tests.
6. Will I lose my hair while taking Gefitinib?
Unlike traditional chemotherapy, Gefitinib is a targeted therapy and typically does not cause significant hair loss. Some patients may experience minor thinning or changes in hair texture, but it is rarely the total hair loss associated with standard IV chemotherapy.
7. Why is sun protection important while on this medication?
Gefitinib can make your skin more sensitive to sunlight (photosensitivity). This means you may get sunburned more easily. It is highly recommended to use a broad-spectrum SPF 50+ sunscreen, wear protective clothing, and avoid prolonged direct sun exposure during your treatment.
8. How should I store GEFISTERIS 250 tablets?
Store your medication in a cool, dry place, away from direct sunlight and moisture. Keep the tablets in their original packaging and ensure they are stored out of the reach of children and pets. Do not store them in the bathroom or near kitchen appliances that generate heat.
9. What are the signs of a serious reaction to Gefitinib?
Seek immediate medical attention if you experience:
- Sudden, new, or worsening shortness of breath or cough.
- Signs of liver problems (yellowing of the skin or eyes, dark urine, or abdominal pain).
- Severe or uncontrollable diarrhea.
- Severe eye pain, redness, or vision changes.
- Signs of a severe allergic reaction (swelling of the face, lips, or throat).
10. Can I switch from a different brand to GEFISTERIS 250?
GEFISTERIS 250 is manufactured to meet strict pharmaceutical standards. However, before switching brands, always consult your oncologist or pharmacist to ensure you are continuing the correct dosage and to discuss any specific requirements for your ongoing treatment plan.
