Adalimumab

• You must see your rheumatologist regularly to make sure the treatment is working and check for possible side effects.
• You should have regular blood tests as suggested by your rheumatologist.
• It is important to tell your rheumatologist if you have a new serious illness such as a serious infection, cancer or heart failure.
• If you are worried about any side effects, you should contact your rheumatologist as soon as possible.
• If you stop adalimumab for any reason, you must contact your rheumatologist. Failure to do so may mean that your treatment may no longer be funded.
• If you plan to become pregnant, you must discuss the timing with your rheumatologist

You may notice lessening of joint swelling, pain and stiffness, often within the first 8 weeks of starting.

If you stop or delay your adalimumab treatment, you may worsen again. Keep on your treatment, unless told by your rheumatologist to stop or unless side effects occur (see Side effects).

If you stop adalimumab for any reason, you must contact your rheumatologist.

• Medications like adalimumab are very expensive and highly funded by Medicare. Certain conditions must be met to receive it.
• Adalimumab will only be given if your disease is active and if standard treatments have not worked.
• It will only be kept going if it helps your condition. This must be checked between 12 and 16 weeks after the start of treatment.
• Blood tests are needed during your treatment to watch for side effects and decide if the treatment is working.
• How often you have blood tests will depend on what other medications you are taking and what other illnesses you might have. Your rheumatologist will advise on this.

Adalimumab is injected under the skin of the abdomen or thigh. It comes in a pen or a syringe injection.

It can be injected by your doctor, nurse, carer or by you. If injecting yourself, be sure to follow the detailed instructions carefully to ensure the best response. It is particularly important to change where you inject each time.

The usual dose for adults with arthritis is 40mg once every two weeks.

Adalimumab may be used with other arthritis medications including:

• other DMARDs such as methotrexate
• steroid medicines such as prednisolone or cortisone injections into the joint
• anti-inflammatory medicines (NSAIDs) such as naproxen (Naprosyn) or ibuprofen (Brufen, Nurofen)
• simple pain medications such as paracetamol.

You might experience side effects with your treatment. Contact your rheumatologist if you have any concerns about possible side effects.
 
Many side effects disappear when adalimumab treatment is stopped.

Most common possible side effects

• Mild pain, swelling or itching at the site of the injection are very common (up to 20% of patients) but can be reduced by applying ice and antihistamine/steroid creams to the injection site and/or leaving the medication out of the refrigerator for 30 minutes before injecting.
• Headaches, cough, stomach and bowel discomfort may also occur.
• As adalimumab affects the immune system, mild infections, mainly the upper respiratory tract (e.g. colds, sinusitis) may occur more often. Treatment with adalimumab may need to be briefly stopped for a serious infection so contact your rheumatologist for advice.

Less common or rare possible side effects

• Serious infections such as tuberculosis (TB) are seen rarely, and screening for TB is needed before treatment begins.
• Rarely, adalimumab may cause an allergic reaction with itchy, red skin, a rash or a feeling of tightness in the chest and trouble breathing.
• Side effects involving the nerves, such as inflammation of the nerve to the eye, may also occur rarely, causing changes in vision or sensation.
• Very rarely ‘drug-induced lupus’ has occurred with symptoms of rash, fever and increased joint pain.
• Annual skin checks are suggested with any medications that can suppress the immune system as there is a slight increase in risk in skin cancers. To date research and use over 20 years, have not shown an increase in risk of other cancers.

Infections

• If you have a current infection of any kind treatment with adalimumab should not be given until the infection is treated.
• You will need some blood tests and a chest X-Ray to exclude some chronic infections before your first bDMARD.

Use with other diseases
Worsening may occur of the following conditions:

• multiple sclerosis
• moderate to severe heart failure.
• systemic lupus erythematosus (lupus/SLE) People with SLE are not often given adalimumab but each case will be assessed whether safe by your rheumatologist

Use with other medicines

• Adalimumab can interact with other medications. You should tell all your doctors about all medications you are taking or plan to take. This includes over the counter or herbal/naturopathic medicines.

Vaccines

• If you are taking adalimumab you should not be immunised with ‘live’ vaccines such as: MMR (measles, mumps and rubella), Varicella vaccines (Chicken pox/Shingles), OPV (oral polio virus), BCG (Bacillus Calmette Guerin), Japanese Encephalitis or Yellow Fever. Talk with your rheumatologist before receiving any vaccines.
• Pneumococcal vaccines and the yearly seasonal flu vaccinations are encouraged.

More information is available on Vaccinations in Rhematology and COVID-19 vaccination.

Surgery

• If you need surgery for any reason, adalimumab should be stopped before surgery. It can start again after the operation at a time decided by your surgeon and rheumatologist (often once the wound has healed there is no infection).

Use with alcohol

• You may drink alcohol while taking adalimumab. If you are also taking methotrexate you should be cautious about how much alcohol you drink.

Use in pregnancy and when breastfeeding

• It is important to discuss with you doctor if you are planning a pregnancy while on adalimumab.
• It may be used in pregnancy and in men trying to father a child.
• If adalimumab is kept going beyond 4 months of pregnancy it may increase the risk of infection in the newborn when live vaccines may be due. 
• The Rotavirus vaccine should be given within the first 6 months of life. MMR may be given at 6 months.
• There is only limited information regarding adalimumab in breast milk and while small amounts may occur, it does not seem to be harmful.

• Adalimumab should normally be kept refrigerated. If needed, for example when travelling, it may be stored below 25°C for up to 2 weeks and then used or discarded.
• Keep all medications out of reach of children.
