Some do have that listed as a possible side effect, I've read that on some of the past prescriptions safety data sheet that accompanies your med when you pick it up at a pharmacy.
Also when our bodies are battling infection, it is a normal response to feel tired.
Be sure to take all your meds for this, these infections can really nasty, even travel to sinus cavities.
I send you good wishes for a speedy recovery.

Take care now,
