Usage Instructions

How Should This Medication Be Used

Alemtuzumab injection comes as a solution (liquid) to be injected intravenously (into a vein) over at least 2 hours by a doctor or nurse in a hospital or medical office. At first, alemtuzumab injection is usually given in gradually increasing doses for 3 to 7 days to allow the body to adjust to the medication. Once the body has adjusted to the needed dose of alemtuzumab injection, the medication is usually given three times weekly on alternate days (usually Monday, Wednesday, and Friday) for up to 12 weeks. The medications you receive before each dose of alemtuzumab injection might make you sleepy. You will probably want to ask a family member or friend to come with you when you receive your medication and to take you home afterward. Although your condition may improve as soon as 4 to 6 weeks after you begin treatment with alemtuzumab injection, your treatment will probably last for 12 weeks. Your doctor will decide whether to continue your treatment and may adjust your dose depending on how well the medication works for you and on the side effects you experience.

What Dietary Instructions Should I Follow

Talk to your doctor about what you should eat during your treatment. It is important to eat a balanced diet that includes protein and to drink 8 to 10 glasses of water every day. Avoid the following foods that may cause infection: peel or skin of fresh fruits or vegetables; unpasteurized juices or dairy products; certain cheeses; meat or poultry that has been allowed to defrost at room temperature on a counter; and meat, poultry, fish, or eggs that have not been cooked thoroughly. If you develop anemia (low red blood cell count) during your treatment, your doctor may recommend that you eat foods that are rich in iron such as meats, leafy green vegetables, and fortified grains and cereals. You will get the most iron from these foods if you eat them along with foods that contain vitamin C or vitamin C supplements. Your doctor may also prescribe an iron supplement for you to take during your treatment.
