Dutasteride and finasteride have similar risk profiles despite Dutasteride blocking more types of 5AR in the brain. Some users report no mood issues with either drug, and it is suggested that Dutasteride's larger molecular size may limit its ability to cross the blood-brain barrier.
A user experienced severe side effects from finasteride, including mental health issues and physical symptoms, and sought advice on managing post-finasteride syndrome. Suggestions included checking vitamin levels, considering dopamine agonists, and avoiding further psychiatric medications.
