Bacterial Infection
"I&#039;ve seen patient reviews where many terrible side effects of this drug were listed. After that, I was afraid to start taking Cephalexin! But my pharmacist said Keflex has been on the market for decades &amp; most people have no problem with it.  I&#039;m happy to report that I am one of those people! The only side effect I am having is a lot of smelly gas &amp; very smelly bowel movements.(a result of the bad bacteria dying off, perhaps?). But that&#039;s a small price to pay to get rid of the infection in my ankle, so I&#039;m quite satisfied.  Word to the wise: I think that most of the patient reviews we see online are from unsatisfied patients. Most people that have no problem with a medicine probably don&#039;t take the time to post, so keep that in mind."
