What is the most important information I should know about alemtuzumab?
Alemtuzumab can cause life-threatening side effects, including serious medical problems that may occur months to years after you receive this medicine.
Call your doctor right away if you have unusual bleeding or bruising, swelling in your legs or feet, decreased urination, blood in your urine or stools, coughing up blood, a lump or swelling in your neck, a hoarse voice, trouble swallowing or breathing, sudden weakness on one side of your body, or problems with vision, speech, or balance.
What is alemtuzumab?
Campath is used to treat B-cell chronic lymphocytic leukemia in adults.
Lemtrada is used to treat relapsing forms of multiple sclerosis in adults (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.
Alemtuzumab may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before receiving alemtuzumab?
You may not be able to use alemtuzumab if you are allergic to it, or if you have:
- an active infection; or
- HIV (human immunodeficiency virus).
Tell your doctor if you have ever had:
- tuberculosis or other infections;
- a thyroid disorder;
- kidney disease;
- bleeding problems, or if you receive blood transfusions; or
- if you have received any vaccine in the past 6 weeks.
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.
Lemtrada may increase your risk of developing other types of cancer, such as melanoma, thyroid cancer, lymphoma, or leukemia. Ask your doctor about this risk.
You may need to have a negative pregnancy test before starting this treatment. Alemtuzumab 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.
Alemtuzumab may affect fertility (ability to have children) in both men and women. However, women should still use birth control to prevent pregnancy because alemtuzumab can harm an unborn baby.
It may not be safe to breastfeed while using alemtuzumab. You should not breastfeed while using Campath, and for at least 3 months after your last dose.
How is alemtuzumab given?
Alemtuzumab is given as an infusion into a vein. A healthcare provider will give you this injection.
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.
This medicine must be given slowly. The Campath infusion can take 2 hours to complete. The Lemtrada infusion can take 4 hours to complete.
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.
You may be given other medicines to help prevent certain side effects or infections. Take these medicines for the full prescribed length of time.
Alemtuzumab 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.
Alemtuzumab 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.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for your alemtuzumab injection.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose may cause a severe reaction when the medicine is injected.
What should I avoid while receiving alemtuzumab?
Do not receive a "live" vaccine while using alemtuzumab. The vaccine may not work as well or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
While being treated with Lemtrada, avoid foods that may be a source of Listeria infection, or heat them thoroughly before consuming. This includes deli meat, undercooked meat, seafood, poultry, unpasteurized dairy products, or soft cheeses.
What are the possible side effects of alemtuzumab?
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Some side effects may occur during or shortly after the injection. Tell your caregiver if you feel weak, feverish, chilled, dizzy, nauseated, light-headed, or have a rash, wheezing, chest pain, trouble breathing, swelling in your mouth or throat, or fast, slow, or irregular heartbeats.
