Keflex and anxiety

I recently found out that I have a bladder infection due to being dehydrated. My OB doctor prescribed me Keflex and I even asked him if that would cause me to have anxiety and he said no. Well I took it about an hour ago and I'm feeling like my anxiety is kicking in. Ugh! Has anyone experienced this before?
