Copanlisib Injection

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.

Copanlisib injection comes as a powder to be mixed with liquid and given through a needle or catheter placed into a vein. It is usually injected slowly over a period of 60 minutes on days 1,8, and 15 of a 28-day treatment cycle.

Copanlisib injection may cause high blood pressure for up to 8 hours after the infusion. Your doctor will check your blood pressure before you receive the infusion and for several hours after the infusion is completed. If you experience any of the following symptoms after you receive the medication tell your doctor immediately: dizziness, feeling faint, headache, or pounding heartbeat.

Your doctor may reduce your dose, delay or stop your treatment with copanlisib injection, or treat you with additional medications depending on your response to the medication and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment.
