hey Kitty, never tried alphosyl, but i did use diprosalyc ointment along with dovenex oint per scribed by my gp, it worked alright, it was a long time ago,
apparently the diprosalyc can make the dovenex lose effectiveness if you mix the two so my derm discontinued the treatment. diprosalyc worked well with softening heavy plaques on knees and elbows, but once thick areas are smooth i would discontinue as it would probably irritate the area and make the p worse, anyway if you are getting really thick plaques i would use dip but if not i would stay away from it. I realize i actually didnt even answer your post regarding the two meds you were inquring about but i thought i would mention my experience with the diprosalyc ointment,
actually the diprosalyc lotion was the last treatment i used on scalp psoriasis almost 15 years ago and my scalp has been clear ever since, weird but i hope it never comes back on my head. anyway ill stop jabbering now, good luck
regards,
Bryan
