Precautions While Using Campath

It is very important that your doctor check you at regular visits to make sure this medication is working properly. Blood tests may be needed to check for any unwanted effects.

This medicine may cause birth defects if it is used by the mother while she is pregnant or by the father when his sexual partner becomes pregnant. Use an effective form of birth control to avoid pregnancy while you are using this medicine and for at least 6 months after your treatment ends. This is very important whether you are a man or a woman. If a pregnancy occurs while you are using this medicine, tell your doctor right away.

Alemtuzumab may cause a serious allergic reaction which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash; itching; swelling of the face, tongue, and throat; trouble breathing; or chest pain after you get the injection.

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. 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 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.
