Proper Use of alemtuzumab
A nurse or other trained health professional will give you alemtuzumab. alemtuzumab is given through a needle placed into one of your veins.
alemtuzumab is usually given for 2 treatment courses. You will receive alemtuzumab for 5 consecutive days for the first treatment course and for 3 consecutive days about 1 year later for your second treatment course. Each treatment usually takes about 4 hours per day.
You will receive medicines to prevent allergic reactions (eg, steroids) before you start treatment with alemtuzumab.
You must enroll in a prescribing program called Lemtrada™ REMS program in order to begin receiving alemtuzumab. Your doctor will explain the program and have you sign an enrollment form. Be sure to ask your doctor if you have any questions about the Lemtrada™ REMS prescribing program. It is very important that you understand and follow all of the instructions for the program.

Precautions While Using alemtuzumab
It is very important that your doctor check you at regular visits to make sure alemtuzumab is working properly. Blood and urine tests may be needed to check for any unwanted effects. It is important that your doctor check your skin for melanoma (tumor) yearly.
Do not use alemtuzumab if you are also receiving Campath®.
alemtuzumab may cause a rare but serious type of an allergic reaction called an infusion reaction. This can be life-threatening and requires immediate medical attention. Tell your doctor right away if you start to have a cough, difficulty with swallowing, dizziness, fast heartbeat, trouble breathing, chest tightness, swelling in your face or hands, fever, chills, itching or hives, or lightheadedness or faintness while you are receiving alemtuzumab.
alemtuzumab may increase risk of cancer, including thyroid, skin, or lymph nodes. Call your doctor right away if you have a new lump or swelling in the neck, cough, hoarseness or voice changes, neck pain, or trouble breathing or swallowing.
alemtuzumab may cause autoimmune disorders, including immune thrombocytopenia (ITP). Tell your doctor right away if you have a bloody nose, coughing or spitting up blood, small red or purple spots on skin, or heavier than normal or irregular monthly periods.
alemtuzumab may cause a serious kidney problem called anti-glomerular basement membrane disease. Call your doctor right away if you have blood in the urine, coughing up blood, or swelling in your legs or feet.
While you are being treated with alemtuzumab, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. You should receive live vaccines for at least 6 weeks before starting treatment with alemtuzumab. Alemtuzumab may lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not take oral polio vaccine since there is a chance they could pass the polio virus on to you. Also, avoid persons who have taken oral polio vaccine within the last several months. Do not get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.
Alemtuzumab can temporarily lower the number of white blood cells in your blood, which will increase the risk of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, these are precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
alemtuzumab may increase your risk of developing infections. Avoid being near people who are sick or have infections while you are using alemtuzumab. Wash your hands often. Tell your doctor if you have any kind of infection before you start using alemtuzumab. Also tell your doctor if you have ever had an infection that would not go away or an infection that kept coming back. Tell your doctor right away if you have been exposed to someone with chickenpox.
If you are a female, you should have a human papilloma virus (HPV) screening every year to avoid getting a cervical HPV infection.
You will need to have a skin test for tuberculosis (TB) before you start alemtuzumab. Tell your doctor if you or anyone in your home has ever had a positive TB skin test or been exposed to TB.
Do not eat foods that may contain a bacteria called listeria, such as deli milk, unpasteurized milk and cheese products, or not properly cooked meat, seafood, or chicken. Make sure that the food you eat which may contain listeria is heated well when you receive alemtuzumab.
Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding. Use an effective form of birth control to prevent from getting pregnant while you are receiving alemtuzumab and for 4 months after your treatment ends.
Tell your doctor right away if you have unexplained weight gain or loss, constipation, fast, pounding, or uneven heartbeat, feeling cold, swelling of the eye. These may be symptoms of a thyroid problem.
