A member asked:
Will cephalexin (keflex) be effective for strep throat if i used omnicef (cefdinir) 2 weeks ago for the same thing?

Maybe: Maybe but Strep throat is a Gram positive organism. The other meds do kill Gram positive bacteria, many more as well as some Gram negatives. You don't need all those meds. Get a rapid Strep throat swab to see if you need any antibiotics at all. Some urgent cares have them. If its a virus neither med will help. Not good to take left over meds. See a doctor for quickest treatment.
