I have a uti. Was prescribed Trimethoprim 200 mg for 3 days

Resolved Question:

I have a uti. Was prescribed Trimethoprim 200 mg for 3 days on Wednesday. They did not work. GP then prescribed Selexid 200 mg for 3 days. Started yesterday so am almost half way through. Still have symptoms. No pain, no burning sensation but the urgency to pass water most of the time. Does this mean that these drugs are not working or am I being too impatient? 20 years ago I had a bad uti and was prescribed Utinor - norflaxin which I seemed to remember worked very quickly. Thank you.

Dr. David :

This is Dr. David

Dr. David :

you might not have a UTI

Dr. David :

this urgency could be due to overactive bladder muscles which are going into spasms.

Dr. David :

you might need to see a urology specialist and get tried on bladder spasms medications like vesicare or detrol

Dr. David :

which can help decrease bladder muscle spasms.

Dr. David :

hello?

Customer:

My GP told me I had cystitis. I have cystitis 8 years ago with exactly the same symptons and this cleared up immediately with medication.

Dr. David :

antibiotics can help decrease inflammation of the bladder called cystitis.

Dr. David :

but it is not normal to have cystitis for 8 years.

Dr. David :

you could have something called interstitial cystitis which can be very painful inflammation of the bladder.

Dr. David :

you do need to ask to be referred to see a urology doctor

Dr. David :

so you can have a cystosocpy to look inside of your bladder.

Customer:

Sorry, I meant I had an attack of cystitis 8 years ago and it cleared up within a couple of day.

Dr. David :

that cystitis 8 years ago could have been a real urinary tract infection.

Dr. David :

the best way to know if there is a bacterial urinary tract infection is to culture the urine and grow out the bacteria in the urine

Dr. David :

this is called a urine culture test.

Dr. David :

then that bacteria can be tested against different antibiotics to see which one works.

Dr. David :

there are some bacteria which have become resistant to certain antibiotics.

Dr. David :

that is called antibiotic resistance.

Dr. David :

I hope your doctor did a urine culture.

Customer:

Maybe I need to take a sample to my GP. My question was do you think I should be more patient with the Selexid

Dr. David :

your GP should have asked for a sample when the trimethoprim was not working.

Dr. David :

I would finish the Selexid

Dr. David :

and if you still have urgency at that point, ask for a referal to a urologist

Dr. David :

to be tested for overactive bladder condition.

Customer:

Do you think I should be seeing an improvement by now?

Dr. David :

if it was a true bacterial bladder infection, yes, you should have gotten better by now.

Dr. David :

or you could have a small bladder stone irritating your bladder making you have urgency.

Customer:

Ok thank you. I am very worried to have any invasive examination.

Dr. David :

you are welcome

Dr. David :

best of luck to you

Dr. David :

I hope your symptoms get better
