It’s used to treat rheumatoid arthritis and psoriatic arthritis. Occasionally it’s used in severe ankylosing spondylitis.
It’s given as an infusion (drip) in hospital, usually every 8 weeks once treatment has been established.
The most common side-effects include a blocked or runny nose, headache, dizziness, flushing, rash, stomach pain or indigestion. Infliximab can also make you more likely to develop infections.
