Tecentriq (Atezolizumab)

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

  • Product Details


    Tecentriq (Atezolizumab) is a monoclonal antibody medication used to treat various types of cancer, including non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), melanoma, and hepatocellular carcinoma. It works as a programmed cell death ligand 1 (PD-L1) blocking antibody. By blocking the interaction between PD-L1 and its receptors, Tecentriq allows immune cells to recognize and target cancer cells more effectively. It is supplied as an injectable solution.

    There are no known contraindications for Tecentriq. However, it may be advised to avoid taking or using Tecentriq if you have a known allergy to Atezolizumab or any of its components.


    • Before starting Tecentriq, discuss the following with a healthcare provider:
      • Medical conditions, including immune system problems, a history of an organ transplant, or nervous system conditions.
      • Any medications you currently take.
      • Whether you are pregnant or breastfeeding.
    • Tecentriq might not be suitable for everyone. Individuals with a history of severe immune reactions or allergies to similar medications should inform their doctor before starting treatment.
    • As an immune checkpoint inhibitor, Tecentriq can cause an overactive immune system, potentially leading to inflammatory reactions and organ damage. Inform your doctor immediately if you notice symptoms like fever, rash, joint pain, or unusual tiredness.
    • Some people might experience infusion-related reactions, including fever, chills, shortness of breath, or chest pain during or after the administration of Tecentriq. Notify your healthcare provider immediately if you develop any of these symptoms.
    • Let your doctor know if you’re experiencing symptoms like cough, abdominal pain, skin rash, or any other new changes that concern you. Your doctor will do some tests before you start Tecentriq and will keep checking your health during treatment.
    • If you have had or are going to have a bone marrow transplant that uses stem cells from a donor (allogeneic HSCT), using Tecentriq could lead to severe complications, some of which could be life-threatening.
