How do I take rituximab and how long does it take to work?

Rituximab is given through a drip into a vein (intravenous infusion) in hospital. The first infusion takes around six hours, although following infusions will take a bit less time.

Usually two infusions are given two weeks apart. This process is repeated when the improvement is wearing off (from around six months to three years later). Many people have rituximab about once a year.

You may have a steroid injection or infusion first, together with paracetamol and an antihistamine, to reduce the chance of a reaction.

How long does rituximab take to work?

If you respond to rituximab, you’ll probably feel better within 2–16 weeks.
