ARTHRIX capsules: Quick facts, FAQs, Side effects, Warnings

Celecoxib (Sell-e-KOX-ib), the active ingredient in ARTHRIX oral capsules, is one of a group of medicines called Coxibs(also known as COX-2 inhibitors). Coxibs are a type of non-steroidal anti-inflammatory drug (NSAID) used to treat arthritis, pain, menstrual cramps, and fever. Although ARTHRIX can relieve the symptoms of pain and inflammation, it will not cure your condition.

ARTHRIX may help relieve moderate or severe pain associated with arthritis. The common side effects that can occur with ARTHRIX include: stomach pain, constipation or diarrhea, gas, heartburn, nausea, vomiting.

Celecoxib (ARTHRIX) is used to relieve pain, tenderness, swelling and stiffness caused by:

  • osteoarthritis (arthritis caused by a breakdown of the lining of the joints).
  • rheumatoid arthritis (arthritis caused by swelling of the lining of the joints),
  • ankylosing spondylitis ( a chronic inflammatory rheumatic disorder that primarily affects, but is not limited to, the spine).

ARTHRIX is also used to relieve short term pain, in cases such as: 

  • menstrual cramps (period pain).
  • following surgery.
