What is Geftin tablet?
Geftin tablet is a targeted therapy used to treat non-small cell lung cancer (NSCLC) in patients with specific EGFR mutations. It works by inhibiting the epidermal growth factor receptor (EGFR), slowing or stopping cancer cell growth. Geftin tablet is mainly prescribed for advanced or metastatic NSCLC and is taken orally once daily. It is more effective in patients whose tumors have EGFR mutations confirmed by genetic testing.
What is the usual dose of Geftin tablet?
The standard dose of Geftin tablet for adults is 250 mg once daily. It is usually taken as a single tablet at the same time each day. It is not commonly used in children, as its safety and efficacy in pediatric patients are not well established. If severe side effects occur, the dose may be adjusted or treatment may be paused, as per the doctor's advice.
How do I take Geftin tablet?
Geftin tablet should be taken once daily, with or without food. The tablet should be swallowed whole with water. If swallowing is difficult, it can be dispersed in a glass of water and consumed immediately. Avoid grapefruit and grapefruit juice, as they can interfere with the drug’s absorption. Also, St. John’s Wort should be avoided, as it may reduce the effectiveness of Geftin tablet.
For how long do I take Geftin tablet?
Geftin tablet is taken as long as it remains effective and the side effects are manageable. Patients may continue treatment for months or years if their cancer does not progress. Regular monitoring with scans and medical tests is required to check whether the medication is working and if any side effects are developing. If the cancer progresses, alternative treatments may be considered.
What is Geftin tablet used for?
Geftin tablet is used for the treatment of non-small cell lung cancer (NSCLC) that is locally advanced or metastatic and has EGFR gene mutations. It is prescribed mainly for patients who have not received prior chemotherapy. This medication is most effective in patients with specific genetic mutations confirmed through EGFR testing. It is not effective in cancers that do not have these mutations.
How long does it take for Geftin tablet to start working?
Geftin tablet starts working within a few weeks, but noticeable improvements are usually seen after several weeks to months of treatment. Tumor shrinkage or symptom relief may take one to three months. Regular imaging tests like CT scans or MRIs are used to monitor progress. Some patients feel better within the first month, while others take longer to respond.
Is Geftin tablet effective?
Clinical studies have shown that Geftin tablet is highly effective in NSCLC patients with EGFR mutations, improving survival rates and quality of life. Studies indicate that progression-free survival (PFS) is longer compared to standard chemotherapy. However, it does not work well for tumors without EGFR mutations. Research shows that patients with mutations exon 19 deletion or exon 21 L858R benefit the most from this treatment.
How does one know if Geftin tablet is working?
Doctors monitor the effectiveness of Geftin tablet using CT scans, MRIs, or PET scans to check for tumor shrinkage. Patients may also notice reduced cancer symptoms like less coughing, improved breathing, and less fatigue. Blood tests and biomarker monitoring may also be used. If the tumor continues to grow, doctors may recommend alternative treatments.
How does Geftin tablet work?
Geftin tablet is an EGFR tyrosine kinase inhibitor (TKI) that blocks signals for cancer cell growth. It specifically targets mutated EGFR receptors, preventing them from sending signals that cause uncontrolled cell division. This leads to tumor shrinkage and slowed progression of NSCLC. It is most effective in tumors with EGFR mutations, as normal EGFR cells are less affected.
Who should avoid taking Geftin tablet?
Geftin tablet should not be taken by people who do not have EGFR mutations, as it will not be effective. It is also not recommended for pregnant or breastfeeding women, people with severe liver or kidney disease, or those with a history of interstitial lung disease. Patients allergic to Geftin tablet or any of its ingredients should avoid this medicine.
