Rheumatoid arthritis.

Rheumatoid arthritis is a disease that affects the joints. It is an autoimmune disease, meaning that the immune system attacks the body's own tissues, causing inflammation and pain.

Rheumatoid arthritis is the most common chronic inflammatory joint disease. Approximately 2.8 million adults in the United States have been diagnosed with Rheumatoid arthritis


Rheumatoid arthritis occurs when many people are still active, working and raising families.

Although the exact cause of Rheumatoid arthritis is not known, there are certain risk factors:

  • Rheumatoid arthritis is more common in women than men

  • Rheumatoid arthritis is more likely to occur in people who have a family history of the condition


RAYOS releases prednisone about 4 hours after you take the tablet.

You may already be familiar with prednisone. It is recognized as a medication that reduces the pain and inflammation of conditions like rheumatoid arthritis (RA) and polymyalgia rheumatica (PMR).

RAYOS works like traditional prednisone but is different because it is a delayed-release form.

Diseases like rheumatoid arthritis and PMR are most active in the early morning hours, which can result in morning symptoms.
