Key takeaways
Arthrotec (diclofenac/misoprostol) and Voltaren (diclofenac) are both used to treat pain and swelling in conditions like osteoarthritis and rheumatoid arthritis, but they have some differences. Arthrotec is a combination of diclofenac, which reduces pain and swelling, and misoprostol, that helps protect the stomach from ulcers caused by medications like diclofenac. This makes Arthrotec particularly useful for people at high risk of stomach and intestinal ulcers. Voltaren comes in various forms, but doesn't have the added stomach protection. Both medications carry risks of serious side effects like heart attack, stroke, and stomach bleeding, but Arthrotec is especially dangerous for people who are pregnant due to the misoprostol component. Voltaren can be used to treat other conditons, such as migraines and menstrual cramps, while Arthrotec is only approved for arthritis treatment. Voltaren is also available as a lower-cost generic medication.
