Umbralisib

WHY is this medicine prescribed?

Umbralisib is used to treat marginal zone lymphoma (MZL; a slow growing cancer that begins in a type of white blood cells that normally fight infection) in adults whose cancer has returned or did not respond to a certain type of medication. It is also used to treat follicular lymphoma (FL; a type of cancer that begins in the white blood cells) in adults whose cancer has returned or did not respond to at least three other medications. Umbralisib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily.
