Is Cephalexin In The Amoxicillin Family
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
My dentist prescribed me to take cephalexin for my tooth for seven days but for the remaining five days, I switched to amoxicillin. Is it ok?
Its 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
I got diagnosed with whartons duct sialolithotomy I was prescribed amoxicillin and then cephalexin for the bacteria which one is more effective helpme?
Calcification: Calcified blockage of the Parotid Gland duct is not unusual, and may even perforate the duct. Calcification should be removed. Antibiotic coverage is common practice, and your 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
What to do if I am deathly afraid of vomiting so if I am okay with amoxicillin and cephalexin will I be okay taking z-pak (aka zithromax)?
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 like 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

I have had a sore throat for 2 months. I've taken amoxicillin and cephalexin and neither have helped. My doc said there's no sign of infection anymore?
Sore throat: There are various reasons besides an infection that can cause a sore throat. Two of the most common are post nasal drip which might be associated with nasal congestion and cough. 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

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 an 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

I have a uti that won't go away I have been on trimethoprim amoxicillin nitrofurantoin and now on keflex I got rid of it but it came back?
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 went the ER and I told them that I was allergic to amoxicillion. The doctor gave me a prescription for cephalexin. Should I take the cephalexin?
Which of these antibiotics for cold interfere with Yaz (drospirenone and ethinyl estradiol) (birth control pills) - Cefalexin, Ospen, Amoxicillin, or any other in that category?
Antibiotics may interfere with the effectiveness of birth control pills. Have they ever lead to failure of birth control? Not conclusively although it is theoretically possible. Mid cycle spotting could be a sign they are adversely affecting efficacy.
Rifampin, Penicillins like Ospen and amoxicillin can do it. Cephalexin probably not.
Stop them as soon as you can. ...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
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?
Been prescribed Cefalexin and amoxicilin for my sinusitis and ear infection. Do these work well together? It doesn't seem like a usual prescription.
Somewhat: Usually both aren't prescribed at the same time, but your physician may have a good reason for doing it that I'm not aware of. ...Read more
My daughter 16 is a 2 yr survivor of hogkins. She just found a lump in the same area as before. Family dr gave amoxil (amoxicillin). Lump still there. Advice pls.?
See your oncologist: It is very important any enlarged lymph nodes be evaluated. Hodgkins is very responsive to therapy, but can recur. It is a curable cancer even if it does come back. Please call her oncologist asap to have her seen. This may be an infection, but a cancer specialist needs to evaluate her. ...Read more

Will amoxicillin cause Stephen Johnson syndrome I going to family dr face swollen I think tooth infection but med phobic bad and dental phobia?
Stephens-Johnson syndrome is a rare disease that affects fewer than six people per million per year.
Unless you have had SJS before, with amoxicillin or another drug, the chances you will get it are vanishingly small. See your dentist immediately. Perhaps he can treat you without giving you an antibiotic. He can definitely avoid amoxicillin if this is a worry for you. Good luck ...Read more
Severe headache especially behind left eye for 7 days. Had sweats, cold chills and vomiting for 4 days. Family doctor put me on cephalexin 2000 mg.
Eye pain: The best way to start the evaluation would be to see an ophthalmologist for a complete eye examination to see if an explanation can be found for your symptoms or to decide what he next step should be. The initial impression of your family doctor suggests a sinusitis and the use of the antibiotic. If this does not resolve the issue then I would suggest following through with an ophthalmologist. ...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
