Had an allergc reaction to keflex once. In the future can I try unrelated antibios w?

Yes: Keflex (cephalexin) is a member of cephalosporin family of antibiotics which are cousins to penicillins. Be sure to tell your doctors about your all your (drug) allergies, especially types of reactions. We're most concerned about anaphylaxis.

Have ecoliUTI. Dr.gave Keflex as I am unable to take any others. Culture sensitivitysays Intermediate. Canit still work? Alsogave 250mg ceftriaxonesho

Bacteria sensitivity: This may depend in part on how the sensitivity testing is done and whether it has levels suitable for UTI measured. Since cephalexin (Keflex) has higher concentrations in the urine than in the blood it may be quite effective for UTI despite the "intermediate" sensitivity. Good luck. ...Read more

Can keflex 500 mg cure sypillis?

Can keflex 500 mg cure sypillis?

No -- don't take it: Cephalexin is the worst of two worlds for syphilis treatment: It would not work reliably; but it has partial activity against syphilis bacteria and could therefore interfere with future testing for it. If you think you have syphilis or were exposed, you need a penicillin injection; nothing else is reliable. Syphilis kills, causes strokes, and makes people blind. Don't mess around: see a doctor! ...Read more
