What is the most important information I should know about anifrolumab?
Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.
What is anifrolumab?
Anifrolumab is used to treat moderate to severe systemic lupus erythematosus (SLE) in adults who already receive standard treatment for SLE.
Anifrolumab may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before receiving anifrolumab?
You should not be treated with anifrolumab if you are allergic to it.
Tell your doctor if you have ever had:
- an active or chronic infection;
- treatment with a biologic medicine or monoclonal antibody; or
- if you are scheduled to receive a vaccine.
Make sure you are current on all vaccines before you start using anifrolumab.
Tell your doctor if you are pregnant or you become pregnant, or if you are breastfeeding.
If you are pregnant, your name may be listed on a pregnancy registry to track the effects of anifrolumab on the baby.
Anifrolumab may affect your baby's immune system, but having SLE during pregnancy may cause complications such as worsened lupus, eclampsia (dangerously high blood pressure), premature birth, miscarriage, or growth problems in the unborn baby. SLE in the mother may also cause lupus or heart problems to develop in the newborn. The benefit of treating SLE may outweigh any risks to the baby.
Not approved for use by anyone younger than 18 years old.
