What Arabloc is used for
Arabloc is a type of medicine used to treat rheumatoid or psoriatic arthritis. Arabloc helps to slow down the process of joint
damage and to relieve the symptoms of the disease, such as joint tenderness and swelling, pain and morning stiffness.
Arabloc works by selectively interfering with the ability of white blood cells called lymphocytes to produce the disease response
that ultimately leads to pain, inflammation and joint damage.
Your doctor, however, may have prescribed Arabloc for another purpose.
Ask your doctor if you have any questions about why it has been prescribed for you.
This medicine is only available with a doctor's prescription.
Before you take it
When you must not take it
Do not take Arabloc if you:
have any diseases which reduce your body's natural defences such as bacterial or viral infections

are pregnant or plan to become pregnant
are not using reliable birth control
You must not become pregnant while taking Arabloc and for a certain period of time after stopping Arabloc.
Arabloc may increase the risk of birth defects.
Women of childbearing potential must use reliable contraception while taking Arabloc.
Do not take it if you are breastfeeding or planning to breastfeed.
Arabloc passes into breast milk and therefore there is a possibility that the breastfed baby may be affected.
Do not take Arabloc if you are allergic to it or any of the ingredients listed at the end of this leaflet.
Some symptoms of an allergic reaction include skin rash, itching, shortness of breath or swelling of the face, lips or tongue,
which may cause difficulty in swallowing or breathing.
Do not give Arabloc to a child or adolescent.
Arabloc is not approved for use in children or adolescents under 18 years old.
Do not take it after the expiry date (EXP) printed on the pack.
If you take it after the expiry date has passed, it may not work as well.

any of the ingredients listed at the end of this leaflet
any other substances, such as foods, preservatives or dyes.

Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from
your pharmacy, supermarket or health food shop.
Some medicines may interfere with Arabloc. These include:

some medicines used to treat epilepsy
some medicines used for tuberculosis (TB)
These medicines may be affected by Arabloc, or may affect how well it works. You may need to use different amounts of your
medicine, or take different medicines. Your doctor or pharmacist will advise you.
In certain situations, for example, if you experience a serious side effect, you change your medication or you want to fall
pregnant, your doctor will ask you to take medication that will help your body get rid of Arabloc faster.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Arabloc.
