Important information about Cataflam

The active ingredient in Zipsor is diclofenac potassium.

Diclofenac works by blocking enzymes called cyclooxygenase (COX-1 and COX-2), which are involved in the production of prostaglandins. These chemicals are responsible for pain, inflammation, and swelling. By reducing prostaglandin production, diclofenac helps relieve pain and inflammation. This mechanism of action makes it effective for treating moderate acute pain.

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Zipsor. However, the following is a synopsis of the general guidelines for the use of Zipsor:

  • Take Zipsor exactly as prescribed by your healthcare provider.
  • Swallow the liquid-filled capsules whole with water.
  • It is usually taken multiple times a day depending on your prescribed dose.
  • Use the lowest effective dose for the shortest duration possible.
  • Do not take more than prescribed.
  • Avoid taking with other NSAIDs such as ibuprofen or naproxen unless directed.
  • Avoid drinking alcohol, as it may increase the risk of gastrointestinal side effects.
