Interaction Details
There were no interactions found between Durvalumab and Saw Palmetto. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Pharmacist Analysis
-----
On the whole, saw palmetto has very few reported drug interactions due to its lack of effects on liver metabolizing enzymes (e.g., CYP P450 enzymes).
There have been some reports of minor interactions with anticoagulants, estrogens, and contraceptives due to saw palmetto's purported effects on blood clotting and various hormones in the body. However, these interactions have generally only been seen in lab studies and for most individuals, are not considered clinically significant.
As always, however, be sure to talk to your doctor before starting any new medications or supplements so you can be appropriately monitored.

Saw palmetto (Serenoa repens) is a plant native to the southeastern United States and a member of the Arecaceae family. It is a small, palm-like tree with fan-shaped leaves that produces small, white flowers. The fruit of the plant is a small, dark purple berry, which is what is used in dietary supplements.
In traditional medicine, saw palmetto has been used to treat a variety of health conditions, including prostate problems (such as BPH [benign prostatic hyperplasia]) and urinary tract disorders. It is also claimed to have anti-inflammatory and antioxidant properties and to improve hair growth.
Durvalumab Overview
-
Durvalumab is used alone to treat non-small cell lung cancer (NSCLC) that spread to nearby tissues and cannot be removed by surgery but has not worsened after being treated with other chemotherapy medications and radiation treatments. It is also used in combination with tremelimumab-actl (Imjudo) and platinum-based chemotherapy to treat a certain type of NSCLC that has spread throughout the lungs and to other parts of the body. Durvalumab injection is also used in combination with chemotherapy agents to treat extensive-stage small cell lung cancer (ES-SCLC) in adults whose cancer has spread throughout the lungs and to other parts of the body. It is also used in combination with chemotherapy agents to treat biliary tract cancer (BTC; cancer in the organs and ducts that make and store bile, the liquid made by the liver) in adults whose cancer has spread to nearby tissues or to other parts of the body. Durvalumab is also used in combination with tremelimumab-actl to treat hepatocellular carcinoma (HCC; a type of liver cancer) that cannot be treated with surgery. Durvalumab injection is in a class of medications called monoclonal antibodies. It works by helping your immune system to slow or stop the growth of cancer cells.
