What is diclofenac sodium?
Diclofenac sodium is a medication that is commonly used to treat pain, swelling, and inflammation caused by a variety of conditions. It belongs to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs) and is available in various forms including tablets, capsules, injections, and gels.
Some common conditions that diclofenac sodium is used to treat include arthritis, dental pain, headaches, menstrual cramps, and sports injuries. It can also be used to help manage fever and pain after surgery.
Mechanism of action
Diclofenac sodium works by inhibiting the production of certain chemicals in the body that are responsible for inflammation and pain. Specifically, it blocks the action of an enzyme called cyclooxygenase (COX), which is responsible for producing prostaglandins.
Prostaglandins are hormone-like substances that contribute to the pain and swelling associated with inflammation. By reducing the production of these substances, diclofenac sodium helps to alleviate these symptoms and promote healing.
Diclofenac sodium dosage
The dosage of diclofenac sodium can vary depending on the severity of the condition being treated and the form of the medication being used. In general, the recommended starting dose for adults is 50 mg to be taken two or three times per day.
For children, the dosage is determined based on their weight and age. Close monitoring is required when administering diclofenac sodium to children, as it can cause serious side effects if not used properly.

Like all medications, diclofenac sodium can cause side effects. The most common side effects are listed below:
