Cephalexin is an antibiotic it has no narcotics in it, it has no pain relieving abilities. To my knowledge it has no euphoric attributes either.

I have been taking cephalexin so that the infection that I had will not come back and I just wanted to know if it is a narcotic?

Cephalexin (Keflex) is a cephalosporin, not a penicillin. Cephalexin does not contain anything besides a drug base and cephalexin.

Hi there. It's quite typical to be allergic to both Penicillin and Cephalexin:Keflex etc. I am only allergic (in an anaphylactic way) to Keflex, but can take penicillin , that apparently is rare. I would be dubious about taking Keflex again my first reaction was fairly mild, second anaphylactic and just this week had a third which was horrendous! Thoroughly recommend you proceed with great caution! Hope this helps xx

There is no Penicillin in Cephalexin. They are quite separate antibiotics. There can be an overlap with Penicillin sensitivity but you are COMPLETELY WRONG when you say there is Penicillin in Cephalexin. Your ignorance is confusing and VERY unhelpful.

The EXACT same thing happened to my daughter. I have also had that experience. Head to toe hives. While cephalexin ISN'T a penicillin, it can very rarely, 10% of the time, cause a reaction in patients with penicillin allergies/sensitivity. Even though the statistics show a small possibility, we tend to err on the side of caution and avoid cephalexin, also called kelfex.

When I was 11 had a allergic reaction to penicillin(mostly swelling in hands and feet), last year I was given penicillin and with in 15 mins. I started to go into shock. I could hardly breath, itched everywhere, bright red skin and was dieing. My daughter called 911, by the time they got here I could not even stand. It was the most scary event of my life so far. Knowing that my doctor gave me Keflex for UTI, I am afraid to take it. I have had it for 2 days and can't make myself take it. Someone please let me know if I can.

You are full of it...cephalexin aka keflex is not a penicillin but works in the same way to treat bacterial infections. I am allergi to penicillin but not cephalosporins eg cephalexin. Some people are and some people aren't. The only relationship between cephalexin and penicillin is that they fight bacteria in the same manner...thaa is why some people are allergic to both. Cephalexin IS NOT a penicillin derivative!!! Look it up online if you're too stubborn to believe me. Everything written above is factual.

I got allergic reaction (swelling of face & lips) to Penicillin when I was 6 yrs old, now I am 55. I have heard that if the allergic medicine is not taken for several yrs you don't get allergic reaction. Now I have been prescribed Keflex according to my urine culture report for UTI due to bilateral DJ long term stents in obstructed ureters due to retroperitoneal fibrosis because of which bilateral moderate hydronephrosis has occured and kidneys are moderately damaged. Currently I have no symptoms (no fever or urine difficulty) but report says Staphylococcus epidermidis (MSSE) sensitive to drugs all of which are like penicillin. doc has given keflex, plz advice whether to take or not.

I'm really allergic to penicillin so when I got Cephalexin I read the information and thought my doctor made a mistake. I called the pharmacist and they said, only 3% of people react to cephalexin that are allergic to penicillin so you may be in the 3% . I live close to a hospital so i feel a little better i guess you can take the medication while sitting in your car at the emergency entrance of the hospital. I hate how toxic antibiotics are, I think a day will come a super probiotic will be created like they made during world War II that saved numerous soldiers lives. This empowered the body to wellness, without the insane and sometimes tragic side effects of antibiotics; the most toxic antibiotic is Cipro. Buyer beware

It has been clinically proven that around 10% of patients with penicillin allergies are also allergic to cephalexin.

i seem to be allergic to most anti-biotics except Keflex. Is that good for sinutitis?

You should have relief within 48-72hrs. The increased swelling contributes to pain in your leg. Any redness should start to lessen and not look so angry red. Hope you get better.oh yeah been a nurse 20 years

I have gotten a sinus infection after a cold and i havent taken penicillin since i was 10 and got a rash from it but i have a script for cephalexin and i already had taken it just now. Should i be looking for other signs rather than a rash for this use.
