Is meloxicam 15mg stronger than arthrotec (diclofenac and misoprostol) 75mg?

Probably: There isn't a direct comparison in any objective study. However, the maximal FDA recommended dose of meloxicam is 15 mg/day while the maximal dose of Arthrotec (diclofenac and misoprostol) is 150 mg/day so you can draw your own conclusions.

No data available: Neither is really stronger than the other one. Some patients may get a better response from meloxicam than the arthrotec (diclofenac and misoprostol) so if you are not getting much relief from one you may want to try the other. It is a common practice. However, always talk to your doctor before changing the medication.

Similar: Melodic am 15mg daily is the equivalent to 75mg twice a day of arthrotec (diclofenac and misoprostol). They are both nonsteroidal anti inflammatory drugs. Everyone responds to these differently. The one that works the best for you may not help the next person.
