Diclofenac is used for the relief of pain, swelling, and joint stiffness caused by arthritis. Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID).


What is Diclofenac?


Diclofenac is a capsule or tablet form medicine used to treat pain and inflammation. Its active ingredient, Diclofenac Sodium, is one of the groups of nonsteroidal anti-inflammatory drugs (NSAID) that reduces swelling of joints, muscles, and tendons especially around the area of the knees, feet, and hands. Pain associated with dental and minor surgery can be eased by Diclofenac. It also alleviates pain caused by sports injuries, backache, sprain, and frozen shoulder, dislocations, and fractures. 


Diclofenac was patented in 1965 by Ciba Ciegy which is later bought by Novartis. It had been introduced in the United States in 1988, and released as both a sodium and potassium salt, although the latter is more quickly absorbed by the body, which is beneficial where immediate action is required. 


Diclofenac is also available in topical or in gel form and powder packets. It is a generic name for Voltarol, Diclofex, Econac, and Fenactol.


How Does Diclofenac Work?


Diclofenac works by blocking the binding of a certain chemical in your body with cyclo-oxygenase (COX) enzymes. This enzyme helps produce prostaglandin, a group of lipids made at sites of tissue damage or infection that are involved in controlling injury and illness. By blocking the effect of COX enzymes, fewer prostaglandins are produced, which means pain and inflammation are eased.


Who Can and Can’t Take Diclofenac?


This medication is safe for most adults. The tablets, capsules, and suppositories are also suitable for children; however, the higher dosage or the Diclofenac (50mg) is not prescribed for children under 12 years.

If patients have an allergic reaction to aspirin or related drug like ibuprofen or naproxen, they should inform their doctor or pharmacist. Diclofenac shouldn’t be prescribed to patients who had ulcers or bleeding due to bruise in the intestine.

How Do I Use Diclofenac?

  • other medical conditions you might have and other medicines you are taking
  • how you react to the first dose


If you are prescribed to take tablets than the other forms of Diclofenac, swallow the tablet whole and do not crush, chew, or break it.


To reduce the risk of side effects, use this medication at the lowest effective dose for the shortest possible time. Do not increase your dose more than what is prescribed.
