Question 1

can cephalexin  help a uti?

Accepted Answer

Yes : The antibiotic concentrates in the kidneys quite well. If the bacteria is sensitive to cephalexin,  your symptoms of a UTI should go away within 24 hours. If not,  i'd recommend getting it re- evaluated by your prescriber.

Question 2

cephalexin can it cause a uti?

Accepted Answer

No: germs cause uti's not antibiotics

Question 3

i have a uti this is the second time i've had it in 2 weeks i just finished my cephalexin and none of my symptoms are gone what else could it be?

Accepted Answer

Family practice: Get it checked out. Have a culture performed. The bacteria may be resistant to the antibiotic that you were put on.

Question 4

trimothorprim and cephalexin for my uti is not working. what alternatives would you suggest?

Accepted Answer

Urine Culture: If the antibiotics were prescribed without a culture, then you should have a culture off antibiotics. If you previously had a urine culture, a repeat culture is appropriate at this point. You may just have the symptoms of a UTI without an infection. See a urologist.

Question 5

i took postinor2 last dose 9 hours ago. if i take cephalexin 500mg for uti is it gonna effect the effectivness of postinor2?

Accepted Answer

No: keflex goes out entirely by being flushed through the kidneys; it has no effect on other drug metabolism through the liver and no effect on drug absorption.

Question 6

i was prescribed cephalexin since bactrim was not working for my uti... is cephalexin a better choice and most likely will help more or are the odds the same?

Accepted Answer

Different antibiotic: Don’t think ‘better’ with antibiotics. These drugs are quite different in their mechanisms of action and the type of bacteria they control. Bactrim is a good 1st choice for community UTI as it covers most pathogens. I hope your doc got a urine specimen to determine which organism is causing  your problem, cephalexin is a good 2nd choice. Add cranberry or blueberry juice daily to help!

Question 7

i am diagnosed with uti and taking cephalexin. i am actively trying for a baby.does medication stop me from conceiving?

Accepted Answer

No: That medication has no effect on conception or on a baby if you were pregnant.

Question 8

when will the diarrhea stop from cephalexin? i'm on my 5th day and started diarrhea yesterday afternoon uti in now clear 500mg for 10 days

Accepted Answer

Here are some ...: For most of uncomplicated female UTIs, a 3-5 day course of antibiotics should be more than needed if bug is sensitive to it. So, you may stop it since you got its related diarrhea and see. If not subsiding in 3 days as expected and wished, seek pro-evaluation especially at the time having fever + persistent  worse diarrhea. Best wish ...

Question 9

hi i have been having uti symptoms.  i went to my doctor and did a test and it came back positive.  i took my course of cephlexin and still have it.

Accepted Answer

UTI: You should take the antibiotic for 7- 10 days consistently. You may want to consider Bactrim, Macrobid or Cipro (ciprofloxacin) as antibiotic alternatives. Drink plenty of fluids and consider cranberry juice.

Question 10

i understand that cephalexin 250mg once nightly long term for uti will fail to work at some point? is it the same with hiprex and is hiprex long term safer?

Accepted Answer

: I answered your question yesterday about these 2 drugs which are used as the suppressive therapy for recurrent lower urinary tract infection.
Both will fail at some time in the future due to resistance (Cephalexin is an antibiotic, Hiprex is an antiseptic), none is safer than the other per my opinion.
I, myself, do not favor suppressive therapy for recurrent UTI.
