One of the side effects of cephalexin is it can cause pseudomembranous colitis. If you were to give a percentage, how likely is this to happen?

Cannot: Clostridium difficile colitis occurs when you alter the normal colonic flora with antibiotics and it grows out and produces toxin. Whether this happens depends on whether you were previously colonized with this organism, the strain in your colon and other factors. No specific %s are available. Don't use antibiotics unless absolutely necessary. ...Read more

I was prescribed 500mg of Cephalexin for a small cut on my toe. I read the side effects of this antibiotic and I am weary about taking it 4 X a day.

Doctor, I am beyond worried. My 3month old suddenly was oozing yellow sticky pus on one side of his head. The emergency room gave him mupirocin and cephalexin. Is this ok? I can't stop crying. Will my only breast fed baby be ok? Please respond. Please!

Abscess: I am assuming the oozing was from his scalp and not his ear right? So it sounds like your son developed an abscess and it ruptured. The antibiotic and the ointment you were prescribed are absolutely appropriate. I recommend close follow-up with the pediatrician to make sure that all is healing well. Keep the area clean, monitor for increasing redness or swelling.Complete all medicines exactly directed ...Read more

Please can someone help me I have pain under the leftbreast onthe far side its a off and on pain can I take cephalexin?

Please can someone help me I have pain under the leftbreast onthe far side its a off and on pain can I take cephalexin?

Wait on cephalexin: There's nothing you're describing that makes me think this is an infection... Which is what you would take Cephalexin for. I would strongly recommend seeing a doctor before taking any antibiotics. When you take antiobitics when you don't need to, you run the risk of unnecessary allergic reactions, yeast infections, and resistant bacteria. Please see your doctor and get a thorough exam. ...Read more
