Doctors confuse dosing of finasteride

I am a 21 year old male from India and I have been using the generic Finasteride 1mg for the last 1 year. I have had good results and almost no thinning in the past year. I have been to 3 dermatologists and they want me to discontinue Finasteride even though I have zero side effects. Upon asking the need to discontinue the drug, one said Finasteride should not be taken long term.
