I'm Just Wondering If My Doctor Might've Messed Up My

I'm just wondering if my doctor might've messed up my medications. I picked them up today and there are what seems to be two medications for controlling/reducing my cholesterol and I'm just concerned as to how they may interact with each other. One is Pravastatin 20 mg and the is Colestipol 1GM (2 tablets, quite large) both to be taken once daily. Should I just wait and call the doctor Tuesday or is it okay to take both at the same time, thank you!
