keflex-500mgKeflex is in a group of drugs called cephalosporin antibiotics. Keflex fights bacteria  in the body.

How we use this drug:  Keflex (cephalexin) is a favorite for acute eyelid infections.  There is a small chance that patients who are allergic to penicillin drugs may not tolerate Keflex.  In that case Ceftin (cefuroxime) would be our first choice for an alternate drug.   Other considerations are Bactrim (Sulfamethoxazole / trimethoprim), Levaquin (levofloxacin), or erythromycin.

Dose:  500 mg twice a day for 1 week.  Take Keflex with a full glass of water – with or without food.

Supplied:  250mg / 500mg / 750mg
