Francesca (4 years ago):

I have been on pristiq for two weeks 50mg. I don't feel any change or improvement. Can someone
advise me as to how long does it take to actually
notice an improvement? Previously i was on paxil
20mg. which made me feel like a detached person
could not stand that feeling.

  • From this study (3 days ago):

  • I had a small amount of the hyperpigmentation between the nose and mouth (mustache area) before starting any of the drugs listed above, however, I was on Methadone at the time. That was about 3 years ago. Over the last 2 years it has spread to my cheeks & chin as well. Basically I have darkened skin in the areas of the face that a beard would cover, which causes me to look like I have a beard and mustache.
