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. Before you 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

prostaglandin medicine, or any of the other ingredients in
