I was just prescribed 500 mg of cephalexin, as a precaution. Since I am having a surgery soon. It seems like I have to pee literally every 5 seconds. Is this a common side affect, or does it mean I'm allergic? I started taking it yesterday after noon, and am supposed to take it 3 times a day. I have taken 4 so far.

Increased urination is not a known side effect or allergic reaction of cephalexin. Hope it has resolved by now. If it hasn't then I would recommend that you see your doctor ... to check that you don't have a urinary tract infection.
