Cephalexin
"I have been prescribed Cephalexin twice so far; each time for foot surgery to prevent infection. The first time, I had no problems. This time, however, I am finding that I am extremely gassy, although I haven't seen this as a side effect anywhere. The only other medication I am on at the moment is 800 mg Ibuprofen but I have only taken one of those so far. I also find myself waking up to a bit of a sore throat and tonight I had a coughing fit and feeling like I was going to throw up. I'm not sure if this is the cause of the Cephalexin, but I just thought I'd share."
