community After praising finasteride on this sub for a while I realised it gave me Brain Fog. I think its related to inhibiting GABA and interferring with mirtazapine (an antidepressant).
Finasteride caused brain fog and reduced the effectiveness of mirtazapine for the user, leading them to stop finasteride and notice improvements in motivation and focus. The user suggests that finasteride might be incompatible with mirtazapine for some people and recommends mirtazapine for those experiencing mental fog from finasteride.
