MHRA updated safety warnings for psychiatric side effects and sexual dysfunction:
The MHRA has reviewed the evidence for finasteride and dutasteride and the risk of suicidal thoughts and behaviours and has recommended further measures to minimise this risk. The product information for finasteride and dutasteride containing medicines is being updated to provide more information on these side effects. The UK ‘Finasteride Patient Cards’ already introduced in 2024, highlight the risks of psychiatric and sexual side effects. (see below)
- finasteride is associated with low mood, depression, suicidal thoughts and sexual dysfunction (decreased sex drive, erectile dysfunction and ejaculation disorders)
- before taking finasteride, read and keep the Finasteride Patient Card and patient information leaflet within your pack and inform your doctor if you have any personal history of depression or suicidal thoughts
- if you have seriously harmed yourself or feel you are at risk of serious harm, contact emergency services on 999 immediately
- stop finasteride 1mg immediately if you develop depression or suicidal thoughts and contact your doctor as soon as possible
- if you are prescribed finasteride 5mg or dutasteride and you develop depression or suicidal thoughts, contact your doctor as soon as possible
- if prescribed finasteride or dutasteride and you experience decreased sex drive, difficulty having an erection or ejaculation problems you should contact your doctor for medical advice
