What is in this leaflet
This leaflet answers some common questions about Plaquenil Tablets. It does not contain all the available information.
It does not take the place of talking to your doctor or pharmacist.

What is Plaquenil used for
Plaquenil may be used for any of the following conditions:
Rheumatoid arthritis is a form of arthritis with inflammation of the joints, characterised by stiffness, swelling and pain.
Plaquenil may be used for short or long-term rheumatoid arthritis treatment.
In treating rheumatoid arthritis, Plaquenil may slow down the process of joint damage and relieve the symptoms of the disease.
Systemic Lupus Erythematous (SLE)
SLE is a disease in which a person's normal immunity is upset. The body produces an excess of blood proteins called antibodies
and these antibodies may cause problems in any organ of the body.
These antibodies may end up, for example, in the skin causing a variety of skin rashes or deposit in the kidney, brain, lung
and joints causing injury.
Discoid Lupus Erythematous (DLE)
DLE is similar to SLE except it only affects the skin and is characterised by a scaling, red rash.
Malaria (treatment and control of symptoms)
Malaria is an infectious disease caused by the presence of parasites in red blood cells.
The disease is characterised by chills, fever and sweats.
In malaria, Plaquenil destroys the harmful parasite which causes the illness.
Your doctor may have prescribed this medicine for another reason. Ask your doctor if you have any questions about why Plaquenil
has been prescribed for you.
Plaquenil is not addictive. This medicine is available only with a doctor's prescription.
