Drug Description


Voltaren Rapid K is used for short-term treatment of various conditions, including migraine headaches, menstrual pain, muscle pain, dental pain, and joint pain caused by osteoarthritis or rheumatoid arthritis. It can provide quick relief, with effects starting as early as 15 minutes after taking the medication. 

Voltaren Rapid K contains the active ingredient diclofenac potassium, which belongs to a class of medications called non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs work by inhibiting the production of certain chemicals in the body called prostaglandins. Prostaglandins are responsible for promoting pain and inflammation as part of the body’s natural response to injury or illness. 

Use and Dosage 

Voltaren rapid k tablet and its generic Diclofenac Potassium come in the form of 50 mg tablet to take it by mouth usually 2-4 times a day. Take the tablets with a glass of water. You may take them with or without food, although taking them with food can help reduce the risk of stomach upset. Do not chew, crush, or break the tablet as it can affect its effectiveness and increase the risk of side effects. Swallow the whole tablet once.  

Take two tablets initially. You may take another one to two tablets every 8 hours, as needed. Do not exceed 8 tablets in a 24-hour period. Take Voltaren Rapid K tablets as soon as you experience pain or as directed by your healthcare provider. The tablets are designed for short-term use to provide quick relief.
