Is Keflex safe to take for the duration of my pregnancy to prevent kidney infection/preterm labor?

Posted by Grantsmom

I am 13 wks pregnant with my 2nd child. My first child was born 8 weeks early due to a kidney infection I had. For  this pregnancy, my NP put me on 500mg of Keflex for the duration of my pregnancy. This seems like a high dose to me and it seems strange to take an antibiotic for 29 more weeks. Have you heard of this? Please advise

When I was pregnant I was on Macrobed once day everday to prevent kidney/bladder/uti infections. I get them constantly. Even now. Towards the end of my pregnancy they switched me to keflex (cephalexin) and during the birth they injected an antibiotic into my iv to prevent anything going to my baby. It is safe if you follow directions on bottle and drink plenty of water! Water is the key! Seriously. Can't stress it enough. My son is great and healthy. If you are still pregnant or breastfeeding, I even recommend LIPIL DHA ARA supplement. It is great. Good luck.

Hi there -

Most antibiotics are Category B, which means that there is no known association with birth defects or other pregnancy-related complication and the drug is probably safe.

(Kflex is a category B drug)

These include:

Augmentin (amoxicillin-clavulanate)
Macrobid (nitrofurantoin)
Flagyl (metronidazole) (although there is some controversy about taking it by mouth in the first trimester)
Cephalosporins including: Keflex (cephalexin), Ceclor (cefaclor), Duricef (cefadroxil)
Cleocin (clindamycin)
Erythromycin (all forms)
Zithromax (azithromycin)
Sulfa drugs (until near term)
Famvir (famciclovir)
Zovirax (acyclovir)
Valtrex (valacyclovir)
Clotrimazole-vaginal (Mycelex, Lotrimin)

Your OB wouldn't have prescribed it during pregnancy if it wasn't safe, and 500 mg dose is typical and standard dose for Kflex.  I took that antibiotic during my pregnancy, my Perinatologist rx'd it.

does Microbid 100 mgl during 1 month of preagnacy is ok?
