I wanted to post here because it is very rare to find someone else who was on Viibryd, let alone on a low dose, and is having similar symptoms. I’ve noticed via other PSSD forums and the comment sections of PSSD articles that those of us who took Viibryd seem to have the worst of sexual dysfunction appear after discontinuation. Others with PSSD from traditional SSRIs simply have a continuation of symptoms that were present while on their medications. I am not sure if this is in some way related to the 5HT1a partial agonist function of the medication.

I was on 10mg for 10 months and it was sufficient despite my very serious acute depression due to the loss of my partner (by the way, 5mg is the lowest I’ve heard anyone take..that’s literally half the pill of the starter dose). While on it, I had on and off issues with insomnia, the common gastro issues, and pretty mild sexual dysfunction (noticeably numb penis when erect with pleasureless orgasm for the first few weeks, then an ~80% return to baseline for the remaining 9 months). I tapered for 2 months, cutting pills, and came off the Viibryd without any difficulty.

3 months later, my symptoms started to worsen. Instead of returning to baseline from 80% functionality, I’ve dropped to ~50% functionality. I have no libido, significant reduced semen volume, and while I am able to orgasm with manual stimulation, I have a very hard time maintaining an erection during intercourse. Even with manual stimulation, the second I stop, I lose the erection within a few seconds. I’m trying to be balanced and consider psychological factors such as stress not anxiety, but I am actually in a good place in my life right now.

By the way, did you have any periods of itchiness/stinging sensation after discontinuation? I had a couple of such windows and it was hell!

Given the low prevalence or at least disclosed low prevalence of our symptoms, and the complexity of the symptoms, I doubt any major work will be done. Mayo is know to have a great publicity machine, hence this forum and many other Mayo interfaces, but our concerns will just get lost. I live in NYC and have attempted to work with neurologists and neuropsychiatrist affiliated with Cornell Weill and they looked at me like I was making things up.
