TLDR Taking Propecia might lead to the development of cataracts.

In 2004, a case study was conducted on a 43-year-old man who had been taking finasteride (Propecia) for 3 years to treat early stage androgenic alopecia and presented with decreasing vision in both eyes over a period of 3 months. The study suggested that Propecia might be associated with the formation of anterior subcapsular lens opacities, a type of cataract. The patient's cataracts might also be associated with alopecia, as both are ectodermal disorders. However, no dermatological findings were found in the patient or his family. The study concluded that although finasteride, the active ingredient in Propecia, is generally well-tolerated, it can be associated with the development of cataracts. Clinicians were advised to be aware of this potential side effect and report suspected cases to the appropriate regulatory bodies.

community Why is everyone not directly advised Dutasteride?

in Finasteride/Dutasteride 169 upvotes 8 months ago

Dutasteride is less commonly prescribed for hair loss because it is not FDA-approved for this purpose, unlike finasteride, which is more accessible and preferred due to fewer side effects. Dutasteride may be more effective in reducing DHT but has a longer half-life and potentially more significant side effects.

Belgium disagrees with the EMA and does not authorize the 1 mg oral form of finasteride for androgenic alopecia, citing a negative benefit-risk ratio. Despite this, some individuals in Belgium can still obtain finasteride through prescriptions, and there is debate over its mental health risks versus its benefits for hair loss and other health issues.
