The most common side-effects are reactions at the injection site, such as redness, swelling or pain. These reactions aren't usually serious.
Regularly changing the injection site will help reduce the chances of this irritation.
Golimumab affects your immune system, so you may be more likely to develop infections.
You should tell your doctor or rheumatology nurse straight away if you develop a sore throat, fever or other signs of infection, or if you have any other new symptoms that concern you. You should see your doctor straight away if any of your symptoms are severe.
You should also see your doctor if you develop chickenpox or shingles or come into contact with someone who has chickenpox or shingles. These infections can be severe if you're on golimumab. You may need antiviral treatment, and your golimumab may be stopped until you're better.
Rarely, people may experience an allergic reaction. Contact your healthcare team if you think you may be having an allergic reaction. If the reaction is severe the drug will have to be stopped.
The long-term side-effects of golimumab aren't yet fully understood because it's a relatively new drug.
Anti-TNF drugs have been associated with some types of skin cancer – these can be readily treated when diagnosed early.
Research so far hasn't shown an increased risk of other cancers.
Very rarely, golimumab can cause a condition called drug-induced lupus, which can be diagnosed with a blood test. The symptoms include a rash, fever and increased joint pain.
If you develop these symptoms you should contact your rheumatology team. This is usually mild and clears up if golimumab is stopped.
