I began taking Mobic about a month ago. I have some acne and rosacea, but I began to develop blister-like acne papules all over my face. I am an esthetician working for a plastic surgeon. I take great care of my skin and thought it would subside eventually. Then I began getting ulcers/blisters in my mouth and my stomach was quite upset. I then recalled a similar reaction to Feldene and few years ago and decided to stop the Mobic. The breakout subsided in about a week and my skin is back to normal.
