Amid growing health concerns, the Medicines and Healthcare Products Regulatory Agency (MHRA) in the UK has issued a serious warning to men using the medication finasteride—a hair loss drug once used by former President Trump.

Men experiencing depression or suicidal thoughts are advised to discontinue use immediately. Daily Mail reported that this recent safety update is due to a notable increase in adverse effects reports associated with the drug.

Finasteride, widely prescribed under the NHS for enlarged prostates and marketed for hair loss through private channels, has been in widespread use among millions globally. The drug functions by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), a known cause of hair loss.

Concern Rises Over Long-term Side Effects of Finasteride

Developed in the 1980s by Merck and Co. primarily for treating enlarged prostates, finasteride was later found to promote hair growth, extending its popularity.

However, some concerning side effects have been reported, ranging from psychiatric symptoms like depression and insomnia to sexual dysfunction, including reduced libido and erectile dysfunction.

Alarmingly, a condition dubbed 'post-finasteride syndrome' has been reported by some users, where individuals continue experiencing these side effects even after stopping the medication. This has sparked increased scrutiny and review by health authorities.

The MHRA's safety review came after a tripling in reports of these severe side effects since 2020, highlighting the rising issue amidst finasteride's accessibility via online companies for hair loss treatments.

US President's Usage Highlights Widespread Popularity

In a high-profile case, former US President Donald Trump was known to take finasteride, underscoring its extensive use.

In the UK, while the NHS prescribes the medication for prostate issues, it is only available for hair loss through private prescription—a testament to its widespread but medically scrutinized consumption.

According to NHS data, nearly 4.1 million prescriptions for enlarged prostates were dispensed in England last year, marking a significant use of the medication in medical treatments beyond hair loss prevention.

Despite the controversies, Merck & Co has denied any link with serious long-term side effects but faced lawsuits in the U.S., where over 700 reports linked to suicide and suicidal thoughts since 2011 emerged from court documents.

New Measures to Inform Users of Risks

In response to these rising health concerns, the MHRA plans to implement new measures to better inform patients about the potential risks. Later this year, 'alert cards' detailing the possible side effects will be added to finasteride packages, enhancing patient awareness and safety.

Dr. Alison Cave, the MHRA's chief safety officer, emphasized the importance of patient awareness, stating that the alert cards will inform men about the psychiatric and sexual side effects to aid in making informed decisions regarding their treatment.

She further advised individuals experiencing depressive symptoms or suicidal thoughts to stop taking the drug and consult a healthcare professional immediately.

She also highlighted the necessity of consulting the medication leaflet, which discusses how to properly take finasteride and outlines its potential side effects, ensuring patients are fully informed of the consequences that may arise from its usage.

Final Thoughts on the Developments Surrounding Finasteride

The MHRA's recent directives reflect a crucial pivot towards prioritizing patient safety in light of the troubling reports associated with finasteride.

As medical practices evolve with ongoing research and patient feedback, the implementation of alert cards and the continuous review of drug effects underscore a responsive and preventative approach to medical treatment and patient education.

The UK's stance on finasteride may serve as a benchmark for international standards in handling medications with potentially severe side effects, ensuring that the benefits of any drug do not outweigh its potential risks to patients.
