Does Propecia or Finasteride Cause Pain on Ejaculation?
I have been taking Finasteride for over 6 years. (I am 32 now) Over the last year or two I have been getting an intense pain when I ejaculate. The pain feels like it radiates from the base of my penis, then it dies down. It feels a bit like a burning sensation.
The pain doesn’t occur every time I ejaculate, but quite often it does. I wonder if this may be caused by Finasteride in some way – such as the drug’s effect on the prostate. The only other side effect I have noticed is watery semen.
Painful ejaculation may be a sign of serious medical issue such as sexually transmitted disease (especially the burning sensation), prostatitis, prostate cancer, etc. I doubt it is related to a drug side effect especially after 6 years but such reports of pain with ejaculation are appearing over forums on the internet. As their appears to be legal actions taken against Merck (manufacturer of Propecia), the motivation for such reporting may be questionable and I do realize it is a very sensitive topic for many readers. In any event, you need to see your primary care provider or a urologist to see if there are medical issues associated with this complaint.
I realize we answer many questions about side effects on Propecia here on Baldingblog. However, not all sexual or penis related symptoms are related to Propecia.
It sounds like you may be experiencing retrograde ejaculation which can be painful and is one of the symptoms included in post-finasteride syndrome along with watery semen which is a common complaint. As suggested in the post, it would be wise to visit a urologist to see if this is something that can be treated.
It is true that Merck is facing lawsuits for failing to warn consumers about the risks of its drug but it is riduculous and disrespectful to insinuate PFS patients are motivated to write about this online for legal advantages. There have been anecdotal reports of post finasteride syndrome for years before any legal activity was initiated and it would only serve to harm the interests of a plaintiff if he were to post online.
