Managing your career after a PFS crash
Work feels harder since PFS? The adjustments you can ask for in the UK, how much to tell your employer, and where else to turn for help.
Post-finasteride syndrome (PFS) can last after stopping finasteride, and for many people it makes work much harder. Focus slips, energy drops and mood sinks. In the UK you can ask your employer for changes to how you work, and you decide how much you tell them.
The UK Propecia leaflet lists problems with erections, sex drive and ejaculation that persisted “after discontinuation of treatment”. Nobody has measured how often that happens, or how many people it keeps from working.
Connor was a tour manager in the music industry when he took finasteride for six months, at 29. In his story on our site he lists “severe brain fog, confusion”, “short-term memory loss” and “an inability to handle stress”. Five years on, he writes: “I am unable to work, and even basic tasks are a struggle.”
So what can you ask for at work, and what help is there beyond it?
How can PFS affect your work?
It depends on your symptoms. People describe brain fog, poor memory, exhaustion, panic and a flat mood that makes it hard to care about tasks. None of it shows on the outside, so colleagues may not see why a meeting has become so hard.
PFS is more than sexual problems. The criteria proposed in 2022 say cognitive problems, depression and suicidal thoughts can occur even without sexual difficulties. Those are often the symptoms that show up at a desk.
Connor’s account above is one person’s experience. There’s no research on PFS and work. What follows comes from UK employment guidance, which applies to many health conditions. Our page on brain fog in PFS and PSSD covers the cognitive side.

What adjustments can I ask for?
Employers must make reasonable adjustments so workers with health conditions “are not substantially disadvantaged when doing their jobs”, says GOV.UK.
Its examples include several that fit brain fog and fatigue:
- Doing things another way: your own quiet desk instead of hot-desking, written notes after meetings.
- Flexible hours: starting later if mornings are worst.
- Working somewhere else: from home on some days, if the commute drains you.
- A phased return: part-time hours for a while after time off.
Ask in writing, say what you need and why, and keep a copy. If your employer says no, ask for the reason in writing. Some people also ask to move to a calmer role in the same company.
Three questions for your manager or HR
- Which of these changes could we try, and for how long?
- Can we agree them in writing?
- When will we review how it's going?
You could start with: "My health has changed, and I want to keep doing this job well. Can we talk about what would help?"
Does the Equality Act cover PFS?
It might. The law looks at how a condition affects you, not its name, and PFS isn’t listed.
Under the Equality Act 2010, a disability is “a physical or mental impairment that has a ‘substantial’ and ‘long-term’ negative effect” on everyday activities. Substantial means “more than minor or trivial”. Long-term means “12 months or more”.
Whether PFS meets that depends on your symptoms and how long they last. Only a tribunal can decide for certain. For advice, Acas and Citizens Advice are free. This is UK law; other countries have their own rules.
What help is there beyond my employer?
Access to Work is a UK government scheme that “can help you get or stay in work if you have a physical or mental health condition or disability”. It can pay for practical support such as equipment or travel, and it offers mental health support.
If you need time off, your GP can give you a fit note. It can say you’re not fit for work, or that you may be fit with changes such as altered hours. After the first crash, when symptoms can be at their worst, time off can give you room to find your feet.
Other people understand. Our WhatsApp peer support groups and forum are full of people who’ve dealt with this at work.
Watch: a career that changed
Chris boxed at a high level before finasteride. In this interview he describes losing his strength in the ring and the depression that followed. It’s one person’s account, and it says nothing about how often this happens.
If you’re still taking finasteride and notice mood changes, the leaflet says to stop and contact your doctor. Any other decision about treatment is for you and your prescriber.
Keep a short note of how symptoms affect your working day. It helps with your GP, your employer and a report.
Report it: it helps everyone
A doctor’s note helps you. A report to the medicines regulator helps everyone else: it is how patterns get noticed.
- No proof needed. A suspicion is enough, even years after stopping.
- Where: the Yellow Card scheme in the UK, MedWatch in the US.
- Use the right words. If symptoms continued after stopping, write Post 5-alpha-reductase inhibitor syndrome (MedDRA 10082430).
Our reporting guide walks you through it
What else do people ask?
Do I have to tell my employer about PFS? GOV.UK guidance doesn’t say you must. You can describe the effect without naming the condition: “I have a health condition that affects my concentration and energy, especially in the mornings.” A letter for your doctor can help if you want it on record.
Can I get sick pay for PFS? If you’re employed and too unwell to work, you may get Statutory Sick Pay. Your employer may ask for a fit note from your GP, and your contract may give you more.
Will my employer find out what PFS is? Only what you choose to share. A fit note or GP letter can describe the effects on work, such as fatigue or poor concentration.
Connor’s story is one of many on our site. If your work has changed because of PFS, your report counts too. Our PFS page is the place to start.
