Iressa® Tablets for EGFR-Mutated Non-Small Cell Lung Cancer

Iressa® is a prescription EGFR inhibitor used for certain non-small cell lung cancers with specific activating mutations. This page explains how it works, who may be a candidate, and how to use it safely, plus Iressa price without insurance. It also outlines access for eligible prescriptions with US delivery from Canada.

What Iressa Is and How It Works

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This medicine contains gefitinib, a tyrosine kinase inhibitor that targets the epidermal growth factor receptor. It blocks signaling that can drive tumor growth in cancers with sensitizing EGFR mutations. It is used in adults after confirmation of the right biomarker. Always rely on your clinician to interpret test results and suitability.

The treatment may be used alone. It is taken by mouth and works systemically. Review the official labeling for a full list of approved uses and limitations.

Who It’s For

This therapy is indicated for adults with EGFR mutation–positive non-small cell lung cancer, as defined in the product labeling. It is not appropriate for tumors without qualifying mutations. People with severe liver disease, significant interstitial lung disease history, or uncontrolled eye disorders may need different care. Discuss pregnancy and breastfeeding, as fetal harm can occur. For more background on the condition, see Non-Small-Cell Lung Cancer.

Dosage and Usage

The labeled dose is 250 mg taken once daily at about the same time. You can take it with or without food. Swallow the tablet whole with water. If you cannot swallow tablets, disperse in non-carbonated water per the package directions and drink immediately, then rinse and drink to ensure the full dose is taken.

Do not change your schedule without guidance. Your prescriber may monitor liver enzymes, skin, eyes, and lungs. If troublesome effects occur, contact your care team promptly. Keep a simple dose log and use reminders to support adherence.

Strengths and Forms

This medicine is available as oral tablets. The commonly marketed strength is 250 mg. Availability can vary by manufacturer and country. Your order will reflect what your prescriber authorized and what is in stock.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to your next scheduled time. If the next dose is soon, skip the missed dose and resume your regular schedule. Do not take two doses together to make up for a missed dose. If you miss several doses, contact your clinician for advice.

Storage and Travel Basics

Store tablets at room temperature in the original blister or bottle. Keep them dry, away from excess heat and moisture, and out of reach of children and pets. Do not store in the bathroom. When traveling, carry your medicine in hand luggage with a copy of your prescription. Use a pill organizer only if you can keep tablets protected from humidity. If your itinerary crosses time zones, maintain a roughly 24-hour interval and note the new local time.

Benefits

This targeted therapy can address tumors that depend on EGFR signaling. Oral dosing avoids infusion appointments. Once-daily use supports routine. Many patients appreciate not needing routine lab-based dose adjustments unless instructed. Learn more about how cancer medicines are used across conditions in our overview, Cancer Drugs List.

Side Effects and Safety

Common effects can include:

• Skin rash or acne-like eruptions
• Dry skin and itching
• Diarrhea or softer stools
• Mouth sores or tender gums
• Nail changes or paronychia
• Eye irritation or dry eyes

Serious but less common risks include interstitial lung disease, severe liver enzyme elevations, corneal ulcer or keratitis, and gastrointestinal perforation. Stop the medicine and seek urgent care if you develop sudden breathing problems, persistent severe diarrhea, or eye pain with vision changes. Your prescriber will advise on contraception and pregnancy risks.

Drug Interactions and Cautions

Strong CYP3A4 inhibitors may raise gefitinib exposure. Strong CYP3A4 inducers can lower levels and reduce effect. Drugs that increase gastric pH, such as proton pump inhibitors, may decrease absorption; timing strategies with antacids or H2 blockers may be recommended by your clinician. Gefitinib can enhance warfarin anticoagulation; INR monitoring may be needed. Avoid grapefruit products unless cleared by your care team. Always share a full medication list, including supplements and herbals.

What to Expect Over Time

Response expectations vary by mutation type, prior therapy, and overall health. Some effects like rash or diarrhea may appear early and can often be managed with supportive care. Your clinician will schedule imaging and periodic lab tests to assess control and safety. Adherence is important; use alarms and keep a weekly checklist.

Compare With Alternatives

Other approved targeted options exist for lung cancer depending on the tumor driver. For EGFR-mutated disease, later-generation inhibitors may be considered based on resistance patterns and safety needs. Two prescription alternatives available at our pharmacy include Tagrisso® and Xalkori®. Your prescriber will decide which therapy aligns with your biomarker results and clinical history.

Patient Suitability and Cost-Saving Tips

Good candidates typically have confirmed EGFR-mutated NSCLC and no contraindications on the label. Those with significant lung scarring, severe eye disease, or active infections need careful assessment. Discuss planned surgeries and vaccination schedules. To manage expenses, consider multi-month fills when appropriate, set refill reminders, and ask your prescriber about supportive treatments that prevent complications. We can clarify Gefitinib out of pocket cost estimates shown at checkout and help you compare options within the Cancer category.

Questions to Ask Your Clinician

• Which EGFR mutation was found, and does it match this therapy?
• How will we monitor response and safety during the first months?
• What strategies help manage rash or diarrhea if they occur?
• Do my other medicines affect absorption or levels?
• What signs mean I should contact the clinic urgently?
• If resistance develops, which next options are likely?
