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.
