The name of your medicine is HYDROXYCHLOROQUINE RBX. It contains the active ingredient hydroxychloroquine sulfate.

It may be used for any of the following conditions:

Rheumatoid Arthritis

Rheumatoid arthritis is a form of arthritis with inflammation of the joints, characterized by stiffness, swelling and pain.

HYDROXYCHLOROQUINE RBX may be used for short or long-term rheumatoid arthritis treatment.

In treating rheumatoid arthritis, HYDROXYCHLOROQUINE RBX may slow down the substances which harm the joints.

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 characterized 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 characterized by chills, fever and sweats. In malaria, HYDROXYCHLOROQUINE RBX destroys the harmful parasite which causes the illness.
