Finasteride and suicidal thoughts: is it real?

MHRA RECOGNISED

What the regulator says

The MHRA Drug Safety Update of 29 April 2024 explicitly named suicidal ideation among the psychiatric reactions for which patients must be counselled. The 11 May 2026 update strengthened these warnings. Patient alert cards in finasteride packs flag this risk specifically. Yellow Card data showed 281 reports for depressed mood or suicidal behaviour at the time of the original DSU.

In plain English

Suicidal thoughts while on finasteride are a recognised, rare but serious adverse drug reaction in UK regulatory wording. The MHRA introduced patient alert cards specifically because these reports needed clearer patient communication. If this happens to you, stop the medication and seek immediate help.

How long does it last

In the regulator's case series, suicidal ideation typically resolved on stopping the medication. The MHRA explicitly recognises that in a small number of cases psychiatric symptoms persist after discontinuation. Whatever the trajectory, the immediate action is to stop and seek help, not to assume it will resolve unaided.

What to do if it happens to you

Stop the medication immediately. Contact Samaritans on 116 123 (free, 24/7). Tell a person you trust. Attend NHS 111 or your nearest A&E. Then contact your prescriber and your GP. Yellow Card reporting helps the regulator's ongoing review but should not delay seeking care.
