What is Alemtuzumab?
Alemtuzumab is a specialized prescription medicine used to treat relapsing forms of multiple sclerosis in adults. You might wonder if this medicine can completely cure the condition.
The honest truth is that Alemtuzumab is not a cure for multiple sclerosis. However, it plays a very important role in protecting your nervous system and improving your daily quality of life.
In multiple sclerosis, your immune system becomes overly active by mistake and attacks your own nerves. Alemtuzumab works by slowing down this overactive immune system, much like gently pressing the brakes on a fast-moving vehicle.
By calming your immune response, the medicine helps prevent your symptoms from getting worse too quickly. It also lowers the number of sudden symptom flare-ups, giving your body more stable periods of rest.
