Me personally, I've not noticed more. I used to get them all the time, pre warfarin use, but I've not had one in several years.

No specific relationship that I heard of.

I do know that during the Einstein Trial for Xarelto it was reported that 7 patients on Xarelto (as compared to 3 on placebo) reported an incident of UTI. Coincidence or relationship - don't know.

Considering UTI's are the most common bacterial infection in both men and women I'd tend to say coincidence.

This is a huge leap so who knows, but I wonder if women who previously drank a lot of cranberry juice prior to taking warfarin stopped doing so out of fear of it messing with their INR. Cranberry juice is known to ease symptoms of and maybe prevent UTIs. Otherwise, I don't know what the link would be.

Many doctors still follow the old school mind set regarding Coumadin and Cranberry (just like foods with Vitamin K). The Anticoagulation Forum did an article that stated intake of Cranberry Juice in Moderation was okay.

To date my own experience is I haven't heard any one complaining about having more frequent UTI's after being on anticoagulants than before. May be a TMI thing or may just not have experienced an increase in incident. I know my young daughter had a serious issue with UTI's when she was younger due to immature valves. At the time one of the NATT board members also served on another non-profit (National Kidney Foundation) so we had a lot of discussions regarding UTI's. I know she hadn't (at the time) had any more incidents of UTI's post Coumadin than she had pre-Coumadin usage.

With all the new anticoagulants and so little being known about them it may prove down the road to somehow contributed to a mechanism that increases the bacteria rate in your body. Don't know at this point.

Sorry, Cavey, not much help on my end but I will ask some of the specialist and see if they know of such a coorelation.

Not me. I didn't have them before I was on thinners and don't have them now that I am.

Thank you all for your replies.

I've been on warfarin for 5 years but it's only the past 3 that I've been suffering with them. I get them at least every couple of months, I've had scans and tests but they can't find a reason I suffer so much. 9 times out of 10 they end up in a kidney infection so I've been put on a daily antibiotic which does seem to have slowed the frequency down in which I get them.
I'd never heard of warfarin making you more prone to them but will be interested in other replies too :-)
