Bear in mind that you must tell your doctor if you have any of the following health issues (i.e. kidney, liver, or heart disease) before you take Carfilzomib. You also should NOT use this drug if you are pregnant or breastfeeding as it can harm your baby. Therefore, using effective birth control is recommended.

Carfilzomib has other side effects that are more common such as nausea, diarrhea, headache, fever, and cough.
