Someone help me please?

I am so sick been with headaches for days then feeling weak. So 2 days ago I got a fever. I woke up the next day and my throat hurted so bad. I decided to go to the hospital I have strep throat they said. They gave me antibiotics and Motrin for the pain. But my body still hurts a lot and head. I really think I have the flu on top of my strep. So I am wondering can I take Theraflu? Even if I am taking the antibiotics? My doctors is not open and its really late dont know what to do any advice?
