Hi, I Am Using The Seebri Breezhaler 50mcg On A

hi, i am using the seebri breezhaler 50mcg on a daily basis. however when i look on the prescribed drugs by my doctor , i found out that there was another medicine prescribed named NOVO-salbutamol hfa 100 MCG which i did'nt take since i bought it. But when I reasearched for both medicines, i found out that both of them are used for COPD patient.
My question is do I have to take both medicines on daily basis?
Thank you
