Why is this medication prescribed?

Copanlisib injection is used to treat people with follicular lymphoma (FL; a slow-growing blood cancer) that has returned after being treated 2 or more times with other medications. Copanlisib injection is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
