Before you take this drug
If you have an allergy to isatuximab, it should be avoided. Before starting the treatment, you may need to take a pregnancy test. Use effective contraception during and after treatment with isatuximab to avoid pregnancy. Exposure to isatuximab during pregnancy could impact your baby's vaccine schedule in the first few months after birth.
If you plan to get pregnant or are already pregnant, do not take isatuximab with pomalidomide. Pomalidomide is capable of causing severe birth defects that can be life-threatening with only one dose. Men and women who use pomalidomide must both use birth control to avoid pregnancy. If you become pregnant while using pomalidomide and isatuximab, tell your doctor immediately.
Breastfeeding is not recommended while taking isatuximab. Isatuximab can increase your risk of developing other cancers. Discuss this matter with your physician.
How to take Isatuximab?
Isatuximab can be infused into a vein. This injection will be given by a healthcare provider. After your first two infusions, you will be closely monitored for at least 30 minutes to ensure that you don't have an allergic response. Isatuximab can be given on a 28-day cycle. It is possible that you will only need to take the medication on certain days during each cycle. Your doctor will decide how long you should take this medication.
Other medications may be prescribed to prevent allergic reactions or serious side effects. Continue to use these medications as prescribed by your doctor. You should read all the medication guides that you receive for other medications used with isatuximab.
Isatuximab may lower your blood count. You will have to test your blood frequently. The results may delay your cancer treatment. It can interfere with certain medical tests. Inform any doctor that you see about your use of isatuximab. Tell the staff if you need a transfusion of blood or plasma and that you're being treated with isatuximab.
