The important points
- Sexual adverse effects and mood changes should be discussed before treatment.
- The EMA confirmed suicidal thoughts as an adverse effect of finasteride tablets; frequency is unknown.
- Patients taking finasteride 1 mg for hair loss should stop and seek medical advice if mood changes occur, following current product guidance.
- A risk discussion supports informed choice; it does not predict an individual outcome.
What the European review changed
In 2025 European regulators endorsed measures to minimise the risk of suicidal ideation with finasteride and dutasteride medicines. Suicidal thoughts were confirmed as an adverse effect of finasteride tablets, with an unknown frequency.
What to discuss before starting
The clinician asks about current and previous mood problems, sexual function, fertility concerns, other medicines and the patient’s preferences. The patient should know which symptoms require prompt contact and where to find the official leaflet.
| Point | Clinical meaning |
|---|---|
| Before treatment | Review mood history, sexual concerns, fertility and medicine interactions. |
| During treatment | Report mood or troublesome sexual changes rather than waiting for the next routine renewal. |
| Urgent risk | Suicidal thoughts or immediate danger require urgent professional help. |
| Repeat prescribing | New adverse effects mean the request is not a routine repeat. |
What to do if symptoms occur
Do not rely on an article to judge severity. Follow the current product information and obtain medical advice promptly. Suicidal thoughts or immediate danger require urgent help through 112 or the appropriate emergency service.
