Beconase nasal spray?

My gp has given me beconase nasal spray due to rhinitis which has started to work but now i have a cold n a mega runny nose and its also bleeding which may be caused by me sniffing alot. Im not sure wether im to keep using the spray as it is not helping at all atm and it also hurts when i use it. I would be grateful for any advice on what to do and whether i shud use something like vicks nasal spray for decongestiant? Thank you
