took finasteride. for 4 months and on the 5th month my throat started closing up at night and i had constant breathing problems,well I looked this up and those are the symptoms of an allergic reaction,but why on the 5th month?I had no side effects at all you would think the first time I took it I would know if I was allergic to it,has anyone had a similiar story?if this is the case what are my alternatives?my regimen now is minoxidil. and the laser comb but I would like some sort of dht blocker any suggestions?
