What specific drug did you use (finasteride, dutasteride, saw palmetto, isotretinoin/Accutane, fluoxetine, sertraline, citalopram, leuprorelin, etc…)?
Finasteride (I was also using topical tretinoin at the time, but I don’t think this caused issues as I had been using it for a while prior without issue.)
What dose did you take (eg. 1 mg/day, 1 mg every other day etc.)?
0.25mg one day, 0.05mg the next day, 0.04mg 2 days later. That was all.
What condition was being treated with the drug?
Male pattern balding
For how long did you take the drug (weeks/months/years)?
3 doses across 4 days
Date when you started the drug?
Start of October 2025
Date when you quit the drug?
Start of October 2025
Age when you quit?
33
How did you quit (cold turkey or taper off)?
It worked out as a taper, but I only started lowering the dose as I read Finasteride was meant to be effective for hair loss even at tiny doses and I decide to try this to reduce chances of side effects. However, I got side effects on the 3rd dose so quit it then.
How long into your usage did you notice the onset of side effects?
3rd dose

What (if any) treatments have you undertaken to recover from your side effects since discontinuation of the drug?
None, it doesn’t look like there’s any reliable / universal treatments? I am just going to try and live a healthy lifestyle for now and look into if diet can have an impact.
If you have pre or post-drug blood tests, what hormonal changes have you encountered since discontinuing the drug (please post your test results in the “Blood Tests” section and link to them in your post)?
I have old blood work from standard check ups. I will be contacting my doctors to get new blood work now this has happened. Once I have the results from that I will post them. I’ve got my old serum testosterone levels handy so will type those below. I’m not sure how relevant serum testosterone levels are to PFS?Note: the reference range listed on my results are is 9 to 29 nmol/L, so Ive always been on the high end. I’m not sure what it will be now.
- 13 years a go: 26.3 nmol/L
- 5 years a go: 27.2 nmol/L
- 1 year a go: 29.0 nmol/L

Nothing to add. I took finasteride for hair loss, got side effects as listed and here I am.
SYMPTOM UPDATES:
3rd Nov 2025…
- Dulled sensation in palms, fingertips, feet, and scalp (noticed when scratching).
- Abs remain constantly tense. I can relax them slightly if I focus, but they quickly tighten again when I stop paying attention.
4th Nov 2025…
- Bodyweight dropping fast, down 2.9kg (6.4lbs) in five days. PFS has shut off my appetite but I’m still trying to eat enough.
- The reduction in sensitivity in my palms, fingertips, feet, and scalp remain.
- Penis sensitivity mostly returned to the head in the morning but dropped to around 10% by evening. Complete loss of shaft sensitivity.
- Zero libido and full ED even with attempted manual stimulation.
- Penis looks smaller, reduced blood flow?
- Balls / groin has been slightly aching today and have mostly been pulled close upto my body.
- Chest tenderness has worsened.
- One plus, my anxiety is lower than yesterday so far; hoping it stays that way when I go to bed, as lying down and closing my eyes to sleep usually worsens it.
5th Nov 2025…
- Constipation since last night. I still haven’t been able to go despite eating a tin of prunes about 8 hours a go.
- My body looks noticeably softer. I’ve always been muscular and in good shape from regular exercise and a physical job, but now I seem to be holding water and looking puffy.
- A dull aching sensation has started in my cheeks for some reason.
- Chest and nipple tenderness has increased.
- The ache in my groin has worsened. To clarify, it’s not the testicles themselves that’s worsened, but close to them.
- Feeling a huge amount of regret and depression today. I don’t feel this is a direct symptom of finasteride like the rest, but more due to the situation I’m in.
I’m not going to do any more updates as things are changing rapidly it seems, for the worse. I might update in the future if things stabilise.
