Finasteride is generally considered safe for many people when taken under medical supervision, but it carries risks of side effects, some of which can be serious. It is FDA-approved as an oral medication for conditions like male pattern hair loss and benign prostatic hyperplasia. However, both oral and compounded topical forms can cause side effects including sexual dysfunction (such as erectile dysfunction, decreased libido), psychiatric effects (such as depression, anxiety, suicidal ideation), and others like fatigue and brain fog. These adverse effects may sometimes persist even after stopping the medication. Women who are or may become pregnant should avoid handling finasteride due to risk of birth defects.
Regulatory agencies like the MHRA and EMA have issued warnings about risks of depression, suicidal thoughts, and sexual dysfunction associated with finasteride, and patient alert cards are being introduced to increase awareness. There have also been reports of local skin reactions with topical finasteride and risks of inadvertent exposure to others, particularly females. Though side effects are uncommon, patients are advised to monitor for symptoms and consult their healthcare provider promptly if they occur.
Finasteride is not recommended for women and children, and men planning to have children should discuss fertility concerns with a doctor before use. Despite risks, the benefits for approved uses generally outweigh these risks under medical guidance.
In summary, finasteride is safe for many individuals when used as prescribed, but users should be informed of possible side effects and monitored regularly by their healthcare provider.
