What Arthrotec 50 is used for
What Arthrotec 50 does
This medicine is used to relieve joint pain, tenderness, swelling and stiffness that may occur in osteoarthritis and rheumatoid
arthritis, whilst protecting your stomach.
Although this medicine can relieve the symptoms of pain and inflammation, it will not cure your condition.
How Arthrotec 50 works
This medicine contains two active ingredients: diclofenac sodium and misoprostol.
Diclofenac sodium belongs to a family of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). These medicines
work by relieving pain and inflammation. However, this kind of arthritis medicine can sometimes irritate the stomach or cause
ulcers because it reduces the amount of natural protective substances (called prostaglandins) in the stomach lining.
Misoprostol is very similar to these natural prostaglandins and can help protect the stomach. Arthrotec 50 therefore helps
protect your stomach while you continue to receive the benefit from the anti-arthritis medicine.
Taking Arthrotec 50
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
Use in children
There is not enough information to recommend the use of this medicine in children under the age of 18 years.
Before you take Arthrotec 50
When you must not take it
Do not take Arthrotec 50 if you have an allergy to:
any medicine containing diclofenac sodium or misoprostol
any of the ingredients listed at the end of this leaflet

not sure if you are taking any of these medicines, ask your pharmacist.
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body
rash, itching or hives on the skin
If you are allergic to aspirin or NSAID medicines and take this medicine, these symptoms may be severe.
Do not take Arthrotec 50 if you have or have had any of the following medical conditions:
a peptic ulcer i.e. stomach or duodenal ulcer

cause a problem in the blood vessels of the developing baby and it may affect labour.

contraception are oral contraceptives ("the pill") or intra-uterine devices (IUDs).
NSAIDs have been associated with reversible infertility in some women.
