1) What Arthrotec is and what it is used for
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 Anti-Inflammatory drugs (NSAIDs).
Although NSAIDs relieve the pain, they can reduce the amount of natural
protective substances called prostaglandins in the stomach lining.
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 Arthrotec
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 6)
• 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
• 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 failure
• 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, or have ever had asthma or an allergic disease
• have an infection, as Arthrotec may mask a fever or other signs of
• 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.
