Evening Primrose Overview
Evening primrose (Oenothera biennis) is a plant native to North and Central America and a member of the Onagraceae family. It is an annual plant that has bright yellow flowers that bloom in the evening (hence the name). The plant produces seeds that are rich in a fatty acid called gamma-linolenic acid (GLA).
Evening primrose oil is a dietary supplement that is derived from the seeds of the evening primrose plant. It is rich in GLA (gamma-linolenic acid), an omega-6 fatty acid, and is sometimes taken to improve the health of the skin, reduce inflammation, and reduce the symptoms of premenstrual syndrome (PMS). It has also been used historically for alcohol use disorder.
Dietary supplements containing evening primrose oil generally are standardized by their gamma-linolenic acid (GLA) and linoleic acid (LA) content.
Atezolizumab Overview
-
Atezolizumab injection is used alone or with other chemotherapy medications to treat certain types of non-small cell lung cancer (NSCLC) in adults. Atezolizumab injection is also used in combination with other chemotherapy medications to treat certain types of small cell lung cancer (SCLC), hepatocellular carcinoma (HCC), and melanoma (a type of skin cancer) in adults. Atezolizumab is also used alone to treat certain types of alveolar soft tissue sarcomas (cancer that forms in muscles, fat, or nerves) in adults and children 2 years of age or older. Atezolizumab injection is in a class of medications called monoclonal antibodies. It works by blocking the action of a certain protein in cancer cells. This helps the person's immune system to fight against the cancer cells, and helps to slow tumor growth.

Your doctor will review your specific type of cancer and past treatment history and other available treatments to determine if atezolizumab injection is right for you.
