DARZALEX FASPRO® and
DARZALEX® can also cause:
Changes in blood tests
DARZALEX FASPRO® and DARZALEX® can affect the results of blood tests to match your blood type. These changes can last for up to 6 months after your final dose of DARZALEX FASPRO® or DARZALEX®. Your healthcare provider will do blood tests to match your blood type before you start treatment. Tell all of your healthcare providers that you are being treated with DARZALEX FASPRO® or DARZALEX® before receiving blood transfusions.
Decreases in blood cell counts
DARZALEX FASPRO® and DARZALEX® can decrease white blood cell counts, which help fight infections, and blood cells called platelets, which help to clot blood. Decreases in blood cell counts are common with DARZALEX FASPRO® and DARZALEX® but can be severe. Your healthcare provider will check your blood cell counts during treatment. Tell your healthcare providers if you develop fever or have signs of bruising or bleeding.
Staying on treatment can be a challenge
