I used to take amoxicillin, then my doctor gave me keflex. I ended up being very allergic to keflex, how am I allergic to one but not the other?
Amox or Penicillin?: Both are commonly prescribed effective antibiotics but it won't matter which one you take as without appropriate dental treatment to remove the cause of the infection, you won't resolve the problem. This requires professional dental treatment. ...Read more
I'm allergic to amoxicillin can I take keflex 500 mg, from what my mom says all that happens if I take amoxicillin is I get a rash but i don't k ow if t?
Most people can: Studies have found a low incidence of cephalosporin (of which Keflex is one) allergy among penicillin allergic people. The rash from amoxicillin is also mediated by immune mechanism other than IgE. Thus, your risk for an allergic reaction is likely no higher than someone who has never had a reaction to amoxicillin. ...Read more
Skin structure: Both antibiotics are efficacious, but Cephalexin (Keflex) is more sensitive for skin structure than amoxil (amoxicillin) if comparing the 2. You should of course discuss with your Doctor who should be evaluating you and properly diagnosing you to Rx the best medication for you. Good luck. ...Read more
What to do if I have strept throat, and im allergic to penicillin, can take amoxicillin or keflex instead?
No : Amoxicillin is within penicillin class and the risk of having a reaction is significant so it should be avoided. There is controversy about the risk of cross reaction between class of antibiotics penicillin and cephalosporin (keflex). It appears the risk is low (but not 0). If penicillin allergy was years ago, skin testing for penicillin can help know if it is still there. Allergist can help. ...Read more

Get checked again: Return to your provider and request a urine culture with sensitivities to definitively identify the bacteria and to treat it with an appropriate antibiotic. Be sure to take the complete course of antibiotics. Also, you may need a pelvic exam to rule out vaginal infections that may be contributing to your recurrent symptoms. Hope you feel better soon! ...Read more
I never took keflex before. I took amoxicilin before, I'm not allergic to it. Is there anyway I can try to see if I'm allegric before I take full dose?
See below: Amoxicillin and Cephalexin have different antibacterial spectra. If an infecting organism is sensitive to both drugs they will work equally well. But if an infection is due to enterococcus Amoxicillin will usually work while Cephalexin will not. Conversely, if an infection is due to mssa Cephalexin will work while Amoxicillin will not. ...Read more
Unlikely: Amoxicillin is in the penicillin family; Keflex is a cephalosporin. Only about 10% of penicillin-allergic people react to cephalosporins, so it is generally ok to take a cephalosporin unless there has been a life-threatening allergic reaction to a penicillin. You should discuss with your physician whether a cephalosporin is appropriate for you. ...Read more
It's almost 3 weeks that I've had a cold.I've tried Zithromax and cephalexin, but they haven't helped. So Now I'm trying amoxicillin. What will happen now?
Stop antibiotics: When cold symptoms don't respond to antibiotics, it is almost never because of a bacterial infection resistant to antibiotics. It means no bacterial infection at all: you have either a virus or allergy symptoms. No antibiotic will help. Taking unnecessary antibiotics is unhealthful, both for you and everyone, by contributing to bacterial antibiotic resistance. Work with your doctor on this. ...Read more

Antibiotic coverage is common practice, and you're treating Dentist or preferably Oral Surgeon is the best one to decide the effectiveness of the antibiotics prescribed depending upon your response to the Meds. ...Read more
What happens if I feel fine taking cephalexin and amoxicillin will I be okay on z-pak (zithromax)?
Different drug: Zithromax is often prescribed to people who are allergic to penicillins (amoxicillin) and cephalosporins (cephalexin). It is possible for a person to be allergic to Zithromax, so monitor yourself closely. There is no good way to predict if you will be allergic to it. I hope this answers your question :) ...Read more
probably: First of all, how do you know you are allergic to augmentin (amoxicillin and clavulanate)? The medication is actually 2 drugs (amomxicillin+clavulanic acid) and can cause rashes that are not due to allergy. Most patients who develop a rash with Amoxicillin can tolerate cephalexin. To be on th esafe side, see an allergist/immunologist. ...Read more

So I had a UTI. Amoxicillin 10 days. Didn't work. Went to ER bc of lots of blood & kidney pain. Now 6 days on cephalexin. When does back pain go away?
Kidney stone: If you are having ongoing pain 6 days into your second antibiotic, either the bacteria is resistant to keflex, or you have a second issue going on as well as a kidney stone that could cause the blood in your urine and the pain. If kidney stones were not excluded in your prior evaluations, they should be looked for. Have your doctor check the culture results from your previous visits. ...Read more

Acid reflux from your stomach which can cause heartburn but also can make your throat hurt. If you have been checked and told there is no infection it would be good to be evaluated for those mentioned. ...Read more
