Contents of the pack and other information

1. What Arthrotec is and what it is used
Arthrotec helps to relieve the pain and swelling of rheumatoid
arthritis and osteoarthritis, and may help to protect patients at
risk of irritation or ulceration of the stomach or intestines.
Arthrotec contains diclofenac and misoprostol. Diclofenac belongs
to a group of medicinal products called Non-Steroidal AntiInflammatory drugs (NSAIDs).
Although NSAIDs relieve the pain, they can reduce the amount of
natural protective substances called prostaglandins in the stomach
This means that NSAIDs can lead to stomach upsets or stomach
ulcers. Arthrotec also contains misoprostol which is very similar to
these prostaglandins and may help protect your stomach.

2. What you need to know before you take
Do not take Arthrotec

If you:
• have had an allergic reaction such as a skin rash, swelling
or itchiness of the skin, severe nasal congestion, asthma or
wheezing after taking diclofenac or other NSAIDs such as aspirin
(acetylsalicylic acid), misoprostol or another prostaglandin
medicine, or any of the other ingredients in Arthrotec (see section
• currently have an ulcer or perforation (hole) in your stomach or
• currently suffer from bleeding in your stomach, intestines or brain
• are undergoing or you have just had coronary artery bypass graft
(CABG) surgery
• have severe kidney or liver failure
• have established heart disease and/or cerebrovascular disease
e.g. if you have had a heart attack, stroke, mini-stroke (TIA) or
blockages to blood vessels to the heart or brain or an operation
to clear or bypass blockages
• have or have had problems with your blood circulation (peripheral
arterial disease)
• are pregnant, or trying to become pregnant, because it may
cause a miscarriage. Women who have not reached the
menopause should use reliable contraception while they are
taking Arthrotec

Warnings and precautions
Talk to your doctor before taking Arthrotec
If you:
• have other health problems such as a disease of the liver or
kidneys. Do not take Arthrotec if you have severe kidney or liver
• previously had an ulcer or bleeding in your stomach or intestines.
Do not take Arthrotec if you currently have an ulcer or bleeding in
your stomach or intestines
• bleed or bruise easily
• have inflammation of the intestines (ulcerative colitis or Crohn’s
• have, or have ever had asthma or an allergic disease
• have an infection, as Arthrotec may mask a fever or other signs
of infection
• are dehydrated
• are over the age of 65 as your doctor will want to monitor you
NSAID medicines such as Arthrotec can cause bleeding or ulceration.
If this occurs, treatment should be stopped. Use of Arthrotec with

another NSAID other than aspirin (e.g. ibuprofen) may also increase
frequency of ulcers or bleeding in your stomach or intestines.
Arthrotec may cause serious side effects, especially stomach
and intestinal complications, if you are using a corticosteroid
(e.g. prednisone), an oral anticoagulant, or a Selective Serotonin
Re-uptake Inhibitor (e.g. sertaline) or if you drink alcohol.
Make sure your doctor knows, before you are given Arthrotec
If you:
• smoke
• have diabetes
• have angina, blood clots, high blood pressure, raised cholesterol
or raised triglycerides
Medicines such as Arthrotec may be associated with a small
increased risk of heart attack (myocardial infarction) or stroke. Any
risk is more likely with high doses and prolonged treatment. Do not
exceed the recommended dose or duration of treatment.
Side effects may be minimised by using the lowest effective dose for
the shortest duration necessary.
As with other NSAIDs (e.g. ibuprofen) Arthrotec may lead to an
increase in blood pressure, and so your doctor may ask to monitor
your blood pressure on a regular basis.
If you have heart, liver or kidney problems, your doctor will want to
monitor you regularly.

your doctor or pharmacist if you are taking, have recently
