How it works

Rituximab is a type of drug called a monoclonal antibody, which are man-made antibodies designed to bind to specific targets in the body. In the case of Rituximab, it targets a type of white blood cell called a B cell and destroys them. B cells play a role in making antibodies and therefore by destroying them, Rituximab suppresses the immune response seen to cause symptoms of myasthenia.

How it is delivered

Rituximab is delivered via intravenous infusion (IV), meaning it comes through a drip into the vein.

When you have it

The IV treatment takes place as a two-dose course with a two-week interval between courses. This will take place at a hospital for a few hours on each occasion.

When starting any new treatment, it is possible to experience unwanted side effects. You will be routinely assessed by your doctor physically and with blood tests to keep on top of any adverse effects. Possible side effects associated with Rituximab are:

• Fever, chills, shivering (within the first two hours of infusion)
