Voltaren Rapid is a prescription medication used to relieve mild to moderate pain and inflammation caused by conditions such as osteoarthritis, rheumatoid arthritis, and menstrual cramps. It can be used to relieve pain and swelling (inflammation) from various conditions such as headache, dental pain, and muscle aches.
