What is Campath?
Campath is used to treat B-cell chronic lymphocytic leukemia in adults.
Lemtrada is used to treat relapsing forms of multiple sclerosis in people 17 years and older (including active secondary progressive disease), after at least two other medicines did not work or have stopped working.
Lemtrada will not cure MS, but it can make relapses occur less often. Lemtrada is not for use in treating clinically isolated syndrome.
Campath may also be used for purposes not listed in this medication guide.
Campath can cause life-threatening side effects, including serious medical problems that may occur months to years after you receive Campath.

Tell your doctor if you have never had chickenpox or if you have never received a varicella vaccine (Varivax). You may need to receive the vaccine and then wait 6 weeks before using Lemtrada.
You may need to have a negative pregnancy test before starting this treatment. Campath may harm an unborn baby. Use effective birth control to prevent pregnancy while receiving this medicine, and for at least 3 months after your last dose of Campath and for 4 months after your last dose of Lemtrada. Tell your doctor if you become pregnant.
If you use Campath while you are pregnant, make sure any doctor caring for your new baby knows that you used the medicine during pregnancy. Being exposed to Campath in the womb could affect your baby's vaccination schedule.
Campath may affect fertility (ability to have children) in both men and women. However, women should still use birth control to prevent pregnancy because this medicine can harm an unborn baby.

How is Campath given?
Campath is given as an infusion into a vein. A healthcare provider will give you this injection. You will be watched closely for up to 2 hours or longer after the infusion, to make sure you do not have a serious reaction.
Campath is usually given 3 times per week for 12 weeks. Lemtrada is usually given in 2 or more treatment courses, separated by 1 year. Your doctor will determine how long to treat you and the number of courses you need. Campath must be given slowly. The Campath infusion can take 2 hours to complete. The Lemtrada infusion can take 4 hours to complete.
You may be given other medicines to help prevent certain side effects or infections. Use these medicines for the full prescribed length of time.
Campath affects your immune system. You may get infections more easily, even serious or fatal infections. You will need frequent medical tests, and your next dose may be delayed based on the results.
You should have a human papilloma virus (HPV) screening every year if you are a female.
Campath can have long lasting effects on your body. You may need medical tests for up to 2 months after you stop using Campath, or 4 years after you stop using Lemtrada.
