Tell us your story, in your own words, about your usage and side effects experienced while on/off the drug.
As trite as is it to write this, in the sense of becoming yet another statistic, this is nonetheless my one and only concrete life, and since I can’t go back and fix mine, I can at least share a tale of caution to others. Please. Your hair is nothing compared to this. I look at men at Norwood 7s and envy them from the bottom of my heart now. Losing hair is incomparably more trivial than losing your health.
So, like many reading this, I noticed my hair thinning with time, and, wanting to hold onto it, I thought I would give finasteride a go, despite five solid years of knowing about how dangerous it was. I suppose that separates me from some here who didn’t know about this risks, as I opted into the game of russian roulette willingly. In my defense, I read the studies showing a strong link to a nocebo effect and side effect presentation, reviewed many sources saying that fin was generally extremely well tolerated, and took comfort in a possible genetic protective factor in that my brother has been taking fin for a year now with no issues. Moreover, as someone with anxiety and paranoid tendencies, I noticed how my mind drastically affects how I perceived my gentials and health, so I thought if anything happened, it would most likely all be in my head, and that if I did get sides, I would just stop fin then and there. Most arguments seemed to point to a worst case senario where, if I did get sides, they would just subside within two weeks. Eventually, there was a moment where my panic over my hair eclipsed the panic I felt over finasteride, and after weighing the pros and cons in March one last time, I decided to try a single half dosage of fin, confident to take matters into my own hands and stop living in fear of a medication that millions of men swear by.

To date, this has been the biggest self-directed mistake of my life, of which there have been many, and every day I wake up with an immediate reminder from my body that I messed up. Only time will tell where I end up now.
What happened? Well, within three hours of taking .5mg of finasteride, I experienced inexplicable testicular pain, and a vague, uncomfortable feeling in my lower abdomen. Immediately I thought it had to be the fin and stopped then and there. I read up on testicular pain, and after scouring the internet, I took solace in reading that the pain should go away in two weeks, or a few, tops. It’s now been seven weeks to the day. It didn’t. It hasn’t.

Instead, alongside the testicular pain, there was a gradual ramping up of new symptoms as the days progressed: I thought my glans felt more rubbery, the pain in my testicles spread to my perineum, which started to feel swollen, then there was a burning like feeling where my hamstrings connect to my glutes, then a feeling like I was wearing underwear made out of itchy wool (I wasn’t), my penis began to feel off, and my hands were falling asleep quicker than usual. Maybe due to desperation, I told myself that it’s maybe possible that somehow, through who knows what mechanism, this was all just nocebo and a terrible bout of paranoia.

That last shred of hope was shattered when, two weeks after taking and stopping fin, my entire body felt like it was burning, like pins and needles were being stabbed into my penis, pelvis, thighs, arms, hands, back, feet, and face, alongside this intense, absolutely beyond-urgent need to urinate every 20 minutes, like I had a full bladder, when only drops were coming out. I’ve had panic attacks before, and anxiety that kept me bed bound in the past. This was something different – something much worse. That same night, the doctor in the ER said that my blood and urine looked okay, aside from my bilirubin being a bit elevated. When I told him about fin, he said it couldn’t be that, so I countered with, “well, could it be PFS?” He then opened up his phone and in real time read an article and went “… it could be. Huh. Never know about that. Best of luck,” and that was that.

Again, it has now been seven weeks. I moved back in with my mom, will soon lose my job do to the intense disability I am now facing, and have been shattered in ways I never could have imagined before this. I have been suicidal before, and once even set out to do it with fairly serious intentions (a plan, a note, supplies, etc.), but this is different. No matter how much my mind shut down before, I always had my body, and I always knew that if I somehow hit rock bottom, I could physically pick myself up. Now, my body and mind have both been shattered by this medication, and for the first time in my life, I feel truly and completely broken, inside and out.

For the most part, most symptoms have died down in the sense that they don’t all hit at once, but they remain present, just in flux. The fully body pins and needles will dissappear for days or a week at a time. It’s been very quite for maybe a week now, and I want to say it’s over. The last several times I did that, however, it came back, and the despair I felt then has diminished my hopes and the scope with which I can conceptualize the future. I now only think in terms of hours and days; weeks, months, and years have lost their significance to me, as I can no longer reasonably predict that I will be up to the task of living in them without debilitating pain and discomfort. So for now, that form of pain is gone.

On a good day, only my testicles will feel dull pain, or I’ll have an odd amount of pressure in my lower abdomen, which I can now sometimes reinterpret as bloating instead of a need to urinate (until the mindtrick fails, which it does, and I’m off to find the nearest restroom). One thing which has not abated in any way, however, is that rubbery feeling in my glans that I thought was present in the beginning, which I know know is just near total numbness – it is always present when I check for it.

So far, I don’t have any erectile issues. The most annoying symptom is my frequent need to urinate, and honestly, I don’t really care at all about the numbness in my glans in comparison. I would trade full numbness in that area for the rest of my life if only I could stop feeling the need to pee in this manner ever again. It wakes me up every few hours and makes it so incredibly difficult to walk for long distances. Forget about going out to dance and listen to music. Tried it, had to leaves after 30 mins due to pain.

I’ve been on this forum nearly every day since day zero, and it’s a double edged sword. I find great solace here, but also indescribable despair at the prospect of permanent damage having taken place in my body, or persistent damage that can takes years to quiet down. I’m now familiar with the advice around here for where I’m at timeline wise: there is no cure (yet), there is no consistent treatment that will help (what works for some can ruin others), there are only guidelines and time. I don’t stay up late, I don’t drink, I workout since, so far, I don’t have muscle wasting, I (reluctantly) stay hydrated (sigh), I’m not on supplements, and I will never touch a 5ar drug ever again.

I know that some improve, some stay the same, and some get worse. It hasn’t been the full three months yet, granted, but my imagination is faltering, and the marginal holistic improvement im feeling 7 weeks now, if it’s even close to being roughly linear, probably puts me on the order of many, many more months of this torment, at least. It will be a miracle if I wake up being at 100% again before the three month mark, so I’m going to call it now at seven weeks and say that this is PFS.

To anyone reading this who is considering fin, I would drop to my hands and knees to beg you not too. I used to think the choice was “bald or not bald”. Now I know if you take fin its actually “bald or potentially disabled (and also bald when the medication cycles out of your body yet the sices remain).” This is not nocebo, this is a real syndrome, and if you get it, you will wish you were just bald.

To the PFS community, my eyes have been opened to this hell and I cannot turn back. I pray to get as close to 100% as I can, and if that happens in the next several months, I will not abandon you all. I will donate at least a thousand dollars of my savings to the cause, with proof. I promise you all. I’ll be back to update at the three month mark after the next 5 weeks, and then every month after for some time.

To anyone who has gone through this, for my own personal relief, could anyone, anyone at all, tell me if their urination issues improved? I know it hasn’t for many, but even just one person telling me it can get better will give me strength to carry on. Thank you in advance if so.


Hi @AnotherFool , and welcome to the forum!

Just awful to see how this drug is turning people’s lives upside down every day… I’m sorry that you’re in this situation!

I was also 27 when I took the drug. I improved a fair bit the first two years, but the improvements stalled after that. It’s quite common to see significant improvements in the first few months, though - it’s so common that we don’t usually refer to side effects as “PFS” until at least 3 months have passed since the last dose. I hope you’ll be one of those cases who improve enough to feel normal in that timeframe.

For now, take good care of yourself, don’t do anything crazy with drugs or supplements, and report your experience to the FDA.

And we’d appreciate any donation you can make to the PFS Network as well.


Hi @M_C, I really appreciate your reply and kindness. I do hope that at three months, I can be somewhat okay again. If it takes a few years to get close to some form of baseline, that would be great too.

I’m sorry that you’re in this boat too, and that things have hit a plateau for you. I used to be a pretty hardline atheist, and while my metaphysics hasn’t changes, the ferver with which I want us all to get better feels akin to prayer recently. I’m sending that out now for you, me, and whoever might be reading this.

Foolishly (really, a fitting username for me), I tried smoking weed last night, just the absolute smallest amount I could, as I’ve read it helped some here. I didn’t consider it a supplement, but still felt nervous. Cue a few hours later when I had a crash just as bad as when I went to the ER. I hope I can recover from this. I forgot just how bad full body pins and needles actually feels. I’m also no stranger to horrid, repulsive dreams, but last night, after somehow managing to go to sleep, I had the worst dreams I can ever, and I mean ever, recall having. It was like the ghost of fin infected my mind last night. At one point, I became lost in a hospital where people were being given fin and butchered, and when I managed to get out, I found my friends who I used to smoke with back in the day, only that their drug use had transfigured them and caused them all breakdowns, until finally, after losing them, as if they had abandoned me, I wound up running through my home to try to find my bed for some reprive, but when I got there, there was some wretched object which began narrating how much I messed up, all the while I started being strangled by a presence I couldn’t see, but which mocked me for having taken fin and smoked, and I was powerless to resist. I don’t want to give the dream too much power, but it was an uncanny representation of my life at this point, and I see it as a warning to stop any and all pharmacological attempt at recovery. From now on, in addition to not touching a 5ar inhibitor, I will not touch weed, coffee, or any substance with a chemical I don’t recognize. I rolled the dice seven weeks ago and got burned, then rolled the dice again last night and got incinerated.

In my own little way, I’ll pray for us all.

To anyone reading thinking of smoking during all this: you’re gambling your one and only recovery.

This is my 3 month update.

The sensation of pins and needles stabbing my body seems to be on a downward trend with longer windows of remission, which is encouraging. When the sensation does occur, hightened stress mainly seems to precipitate it, such that the biggest trigger appears to be intense fear that the issue will occur in the first place. I do not think this points to phenomenon being entirely psychosomatic at bottom, however; rather, I think while there is a psychosomatic component that mediates the sensation, ultimately, there has been a physical change in my body which has caused me to now be susceptible to stress induced pins and needles. The pins and needles also don’t seem to be as widespread on the whole, and when there is a bad flare up, I generally don’t worry that it will be forever now. My mind feels more fragile though, so after a few days of consistent pain in this way, my hope diminishes until the feeling goes away entirely, at which point it becomes easier to be positive again. It’s become a familiar pattern, and there is some comfort in knowing the contours of how it plays out.

Frequent urination is still ongoing. A lot of nights now I don’t wake up from it, but I still feel odd in my bladder and like I have to pee much more often tha pre-fin. I still find this symptom to be one of the most distressing for some reason. Probably because of the shame around urination problems, and because of how limiting it can make physical activity.

Muscle twitching was at its worst a few weeks to a month ago. It never hurt, but the twiching itself was so violent that it was hard to sleep some nights.

Still no issues with erections, but my sex drive was virtually non-existent until about a week ago. I try not to worry to much about my libido, and for the most part I don’t as I didn’t care a ton about sex pre-fin anyways. Don’t want to suggest that I’m being apathetic or passé about sex because it somehow doesn’t matter though - it certainly does, and I hope everyone afflicted with sexual sides recovers. For me, I’m still a bit lower on the hierarchy of needs to really worry about sex yet.

I have, for now, regained some sensation in my genitals and body. It comes and goes however - a week or two ago, I felt absolutely nothing in my body or gentials for the first time, and thought I would never come back from that. I did somehow, so I want to convey that there is some hope for those going through genital numbness. I don’t know how much, as it still fluctuates for me, but there is hope nonetheless.

My stomach is upset more days now, I am bloated constantly regardles of diet, and I have bald spots in my beard that weren’t there before. My facial hair is also much thinner than it used to be. I’m 27 so it was getting thicker year by year, but now its like I have lost roughly 5 years worth of progress in three months. Crazy stuff.

The most debilitating issue now is profound exhaustion. No matter now much I sleep, I wake up utterly depleted. This continues throughout
the whole day, every day. I had this problem before fin, but no where near as bad as I have it now. It’s like everything has become collasal in it’s exertion cost to me, and I find myself floored from sitting up, brushing my teeth, blinking, and steadying my breath.

All in all, I’m in a better place than I was three months ago when I went to the ER. I really didn’t think I would ever feel better. I still don’t feel well, and in fact I am quite sick, despite regaining some functionality from the outside. Inside, I still feel off, bad, really bad, and uncomfortable, depending on the day. At it’s worst, 0% being the ER visit crash, 100% being a good day pre-fin, I spend most time between 50% and 75 or 80%, with the period dip down to 30%.

Hang in there everyone.


4th month (and some change) update.

Still experiencing pins and needles, with possible worsening of symptoms in terms of intensity and area of coverage. My lips were never affected, but today they were.

Urinary frequency is still higher than pre-fin, but a bit better than they were after my crash. I was peeing every hour then and the stream so really slow and difficult to start, and I couldn’t feel it. I can feel it more now, and the stream is much better on the whole.

Muscle twitching is basically gone.

Eyes feel dryer, unfortunately.

Doesn’t seem like, on the whole, things are thaaat much better than they were when I crashed, and the pins and needles in particular are getting difficult to cope with. It’s odd. I cannot imagine several more years of feeling like I’m getting stabbed with needles, but I also couldn’t imagine getting to four months of this either.

I’m reminded of a quote by, I think, dostoevsky, who said that, more or less, humankind is a creature which can adapt to anything. I don’t like the idea of getting used to being in pain an uncomfortable everyday, but what else is there to do on a moment by moment basis?

Hoping things are better next month.

Hang in there everyone.


Mini update: last week from Tuesday to Saturday was my first real window where i felt basically 100%. This week im back in the thick of it, but still, i had a window nonetheless. Hopefully I can have more and longer windows as time goes on.

Stay the course. Don’t take finasteride, minoxodil, or an SSRI. Try to stick to a healthy lifestyle and you should be good. If you’re experiencing windows of your normal self and your health isn’t crashing down around you constantly anymore, then you’re on the way up.


You don’t feel the high pitch sound in your ears(Tinnitus)?

Hey there. No, I don’t have that symptom. I have on occasion had flair ups of tinnitus prior to finasteride, but oddly enough no such episodes have occured post-fin.

Thank you, Dknighten. It’s odd, sometimes I’m having entire weeks of feeling pretty good, and then it will crash (burning in body, pins and needles, etc.) and I’ll be convinced im not getting any better. I’m trying to stay positive. How are you doing?

5 month update.

Having an uptick in urination and bloating again after my 1 week window where i was basically 100%. Bladder feels uncomfortable. Pins and needles still affecting my body. Heart rate pounding at times. Not feeling very well right now. Hoping for another window soon.

the window will last longer and longer,my experience,do not srew it up

Thank you my friend. For me, no supplements, no 5ari, try to sleep well, eat okay, and destress when i can. I hope time helps me heal, and research fills in the gaps soon. How long are you down the road? Are you doing okay?

around 8 months so far,back to 90% normal with some random muscle twitches, I will say that a healthy and peaceful lifestyle and aviding certain food and chemicals can always help.

did you have sexual sides? did they vanish?

did you have sexual sides? did they vanish?

Yes, I have had sexual sides before, mainly impotence, premature ejaculation and watery ejaculate, the impotence problem cleared up pretty quickly after stopping the medication, while the premature ejaculation took nearly 4 months to recover from, and the smell and color of my semen started to become normal just recently.

Did you have problems with penis sensation? sensitivity decreased?

I remember having some similar symptoms in the beginning with sensitivity, but it wasn’t serious compared to other symptoms, so I didn’t pay much attention to it.
