Brukinsa Overview

Reviewed: April 21, 2020
Updated: 

Brukinsa is a prescription medicine used to treat adults with mantle cell lymphoma (MCL) who have received at least one prior treatment for their cancer. Brukinsa belongs to a group of drugs called BTK inhibitors. Bruton's tyrosine kinase (BTK) is a protein that signals to cancerous B cells, helping them to grow and spread. Blocking BTK can help stop this signaling.

This medication comes in capsule form. It is taken once or twice daily. Swallow Brukinsa capsules whole with a glass of water. Do not open, break, or chew the capsules.

Common side effects include decreased blood cell and platelet counts, rash, diarrhea, and upper respiratory infections.
