Neoxidl 2% Spray. Help

[B not Yet]

Hey guys i live in Canada but now am back home for vacation, my doctor prescribed to me Neoxidil 2% spray and Probecia but we dont have rogain only nexoidil which i think similar but less than rogaine . i Will not take propecia. But if i bought the spray, i will get back to canada after a period of time, should i wait and buy rogaine from there or is it ok if i use neoxidil for now and then switch ?? will be there side effects when switching. Thanks
