I'm glad you asked this because I've been having joint pains for some time, among other things.  Up until this moment, I was on the "Prozac-for-life-plan."  That's my way of putting it.  But now I'm wondering if that's really a good thing.

I did a Google search on "Prozac joint pain" and found this:

The list of side effects will blow your mind.  Joint pain is among them.  When I started on it, all of those side effects were not listed.

Welllllll, I think I'll make an appointment with my shrink for next week!

I don't know if this is a fact - but I have been on prozac for several years.  I have severe joint pain and have thought I have early age arthritis.  I guess it makes sense that it is from prozac as I didn't have this problem prior to it.

In the 90's I took prozac (Fen Fen combo) with lack of feeling anything as a result.   Several years later as a result of depression I was put back on Prozac by my doctor.  Within days I started with severe pain beginning in my distal joints (fingers, toes).  Within 3 days it had worked it's way into my elbows and knees so severe that I could not even walk or move.  I literally thought I was dying as nothing counteracted the pain.  The addition of prozac was the only thing that had changed in recent days. I stopped the med and within 3 days the point slowly went out of my joints. After the death of my husband a few years later, I thought I would give it a try again with severe joint pain beginning again in the same manner.  I immediately stopped the drug and now list it as a drug sensitivity.  It is an uncommon side effect that is rarely noticed in the side effects.
