I have a niece that is pregnant and is allergic to Penicillin. Her regular doctor gave her Keflex for what they thought was a bacterial skin infection. Her mother, my sister, was just told that Keflex can cause deafness for an unborn infant. Is this true? Is there a website or someplace I can get information from about this? We are very worried. The skin condition ended up not being bacterial after all. Thanks for all info you can give us. en-us Copyright 2009 Prescription Drug Info All Rights Reserved. 11/21/2009 2:17:10 PM 20 http://www.PrescriptionDrug-Info.com/threads/Keflex-and-Pregnancy-D65159_s2.htm#178362 Yes, according to the FDA reports, it has no known harmful effects on the fetus and is considered safe for use during pregnancy. <br> <br>Did you discuss your concerns with her doctor, though?

I was told to take it up to my delivery that it would be fine for the baby. He is going to be 5 in February and he is just fine and has no signs of anything wrong. Mon, 21 Sep 2009 15:42:01 -0800
