Imfinzi® Injection for Lung Cancer

Imfinzi® is a prescription PD-L1 immunotherapy used for certain cancers. This page explains what it is, who it may suit, and how it is given. We support US delivery from Canada so you can review options for Imfinzi without insurance and discuss next steps with your care team.

What Imfinzi Is and How It Works

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

Imfinzi® (durvalumab) is an immune checkpoint inhibitor that targets PD-L1. By blocking PD-L1, it can help your immune system recognize and attack cancer cells. It is administered as an intravenous infusion in a clinic or hospital. This medicine is used alone or with chemotherapy, depending on the cancer type and treatment plan. It is not a self-injection and is supervised by a healthcare professional.

Durvalumab belongs to the class of PD-1/PD-L1 inhibitors. It may be continued as maintenance therapy after chemoradiation in some settings or started with chemotherapy in others. Treatment plans vary by indication, prior therapy, and your clinician’s guidance. For background on this class of therapy, see our article on Immunotherapy For Cancer.

Who It’s For

This therapy is used in several cancers, including non-small cell lung cancer and extensive-stage small cell lung cancer, based on approved uses. Some patients with biliary tract cancer may receive it in combination with chemotherapy. The specific indication and regimen are determined by your prescriber.

People with autoimmune disease, a history of organ transplant, or active infections require careful evaluation before starting treatment. If you are pregnant, planning pregnancy, or breastfeeding, discuss risks and timing with your clinician.

For search clarity and education, some patients explore Imfinzi lung cancer to learn where this therapy may fit in care pathways. For condition background, visit our categories on Non Small Cell Lung Cancer and Small Cell Lung Cancer. You can also read Lung Cancer Awareness for general education.

Dosage and Usage

Durvalumab is infused intravenously, typically over about an hour. Dosing schedules vary by indication and patient factors. Many adults receive therapy at regular intervals, often every two or four weeks. Your infusion schedule, duration, and any combination with chemotherapy are set by your oncology team using official labeling.

Before each infusion, your care team may check labs and assess symptoms. They may adjust the timing around holidays, procedures, or side effect management. If you are receiving Durvalumab in lung cancer, your team will align dosing with your concurrent or prior treatments and clinical status.

Do not change or skip any infusion without medical guidance. Tell your clinician about new symptoms, especially respiratory issues, diarrhea, rash, eye problems, jaundice, or severe fatigue. Premedications may be used if you had an infusion reaction previously.

Strengths and Forms

Durvalumab is supplied in single-use vials for IV infusion. Common presentations include fixed-dose options suitable for adults meeting weight criteria or weight-based dosing per the label. Availability can vary by market and by the oncology protocol your prescriber selects.

For reference across sources, one labeled presentation often discussed is Durvalumab 1500 mg given at defined intervals for certain adult patients. Your oncology team will choose the appropriate vial configuration and dosing plan.

Missed Dose and Timing

If an infusion is missed, contact your clinic as soon as possible to reschedule. Timing is guided by your prescriber, who may adjust the plan based on how much time has passed and your recent labs or symptoms. Do not try to compensate for a missed infusion without medical advice.

Storage and Travel Basics

Clinics store this medicine refrigerated and protected from light, following the label. Do not freeze. Avoid shaking vials. At home, patients typically do not hold vials, since preparation and administration occur at an infusion center.

If you must transport a dose arranged by your clinic or specialty pharmacy, follow the written instructions closely. Keep it in the original packaging until preparation. Use a cooler or thermal container if instructed. Bring supporting documents when traveling. Keep medicines out of reach of children and pets.

Benefits

This treatment can allow your immune system to better identify and fight cancer cells. It may be used after chemoradiation to help maintain control, or alongside chemotherapy in certain cancers. Infusions at planned intervals can simplify scheduling once a routine is established. Many patients appreciate that no daily tablets are needed for this regimen.

Side Effects and Safety

• Fatigue or low energy
• Cough or shortness of breath
• Diarrhea or abdominal discomfort
• Skin rash or itching
• Decreased appetite or nausea
• Muscle or joint pain
• Infusion-related reactions

Serious risks can include immune-related effects, such as pneumonitis, hepatitis, colitis, endocrinopathies (including thyroid or adrenal issues), nephritis, severe skin reactions, and ocular inflammation. Early recognition matters. Seek urgent care for chest pain, severe shortness of breath, persistent diarrhea, yellowing skin or eyes, vision changes, or severe rash. Your team may hold treatment and use corticosteroids or other medicines to manage immune-mediated reactions.

Drug Interactions and Cautions

Tell your prescriber about all medicines and supplements you take. Live vaccines are generally avoided during therapy. Long-term immunosuppressants may influence how immunotherapy works. Your team will consider steroid timing if needed to treat side effects. Patients with active autoimmune disease, prior transplant, or uncontrolled infections require individualized risk assessment.

Alcohol, smoking, and herbal products can complicate care by affecting organs or other therapies. Share complete information with your oncology team so they can coordinate safely.

What to Expect Over Time

Your clinician may schedule infusions and regular assessments over months. You will have lab monitoring and symptom checks before each dose. Some people feel tired for a day or two after an infusion, while others feel stable. Report new symptoms promptly, because immune-related effects can occur at any time during therapy.

This medicine is used for different cancers and stages, including Durvalumab small cell lung cancer settings when approved. Progress is assessed with imaging, labs, and clinical exams. Your team will discuss when to continue, pause, or stop therapy. Adherence to visits and clear communication help your clinicians respond early to any changes.

Compare With Alternatives

Treatment choices depend on tumor type, stage, biomarkers, and prior therapy. In certain lung cancers driven by EGFR mutations, targeted options may be used instead of or before immunotherapy. Two examples we carry include Tagrisso® and Lorbrena®. These are not interchangeable with immunotherapy; your oncologist selects based on mutation testing and clinical guidelines.

Pricing and Access

We provide Canadian pharmacy transparency so you can compare Imfinzi price and discuss options with your clinic. Many patients look for Durvalumab Canadian pricing to understand potential savings if paying cash. We offer clear product listings and secure checkout. For current offers, visit our Promotions page. Orders include US shipping from Canada with tracking. Final costs depend on dose, number of vials, and your prescribed schedule.

Availability and Substitutions

Supply can vary by strength and market demand. If a specific vial size is unavailable, your prescriber may recommend an alternative or a different configuration to achieve the ordered dose. We also list other oncology medicines in our Cancer category. As applicable, purchases are prescription required and verified.

Patient Suitability and Cost-Saving Tips

This therapy may suit adults whose cancer type and stage match labeled indications or established protocols. It may not be appropriate for people with uncontrolled autoimmune conditions, active infections, recent organ transplant, or severe uncontrolled lung disease without careful specialist oversight. Discuss fertility, contraception, and breastfeeding considerations with your clinician.

To manage expenses, coordinate multi-visit planning with your infusion center. Align refills with scheduled cycles when possible. Ask your clinic about institutional assistance programs and financial counseling. Consider keeping a simple log for appointments, labs, and invoices. If your oncology team requests a quote, we can provide itemized details for your records. If you are comparing options beyond insurance, your clinic can help interpret the price of durvalumab and dosing needs for your plan.
