Hi all.

Okay, sorry for the strange topic, but the past few days, my urine has been smelling really potent, and for some reason it's setting off red flags in my head like something could be wrong.

You know how after you eat asparagus, your urine has that very potent, distinctive smell? That is what it smells like...if not exact, then pretty close.

I remember once my chiropractor mentioned some kind of connection to me, about the urine smell after eating asparagus, being connected to sulfa somehow.

And I've been on Bactrim about a month now. And it contains sulfa.

Could that be why my urine is smelling like I ate asparagus, despite not eating anything even remotely similar to asparagus?

Do I need to go on some kind of sulfer detoxification protocol?

Or is it that asparagus pulls excess sulfa out of the body, so I should actually start eating it now more than ever?

Confused....would like if anyone can enlighten me. It is so sudden and strange that I'm thinking of calling my LLMD.

Okay, so I just googled it, and it is in fact sulfer that give the "asparagus urine" smell (and only 50% of people get it, for those confused as to what I'm talking about).

Has anyone gotten this from Bactrim (not asparagus! haha)? Should I stop the Bactrim?

Another update: This is from Wikipedia:

"Thus, it is now believed that most people produce the odorous compounds after eating asparagus, but only about 22% of the population have the autosomal genes required to smell them.[30][31][32]"

So my guess is that if some (or even most) of us are producing strange sulfur-smelling urine while using Bactrim, that only 22% of us would notice the smell anyways.

But my main concern is is this a sign I am taking too much Bactrim? Or is it just a harmless consequence?

Can't answer your Q Hoosiers, but our family calls asparagus 'stinky pee'. [Smile]

Would you do an asparagus detox just because your urine smells?

Sounds to me like your kidneys are already doing the job for you.

Asparagus is known to cause smelly urine regardless of taking something like Bactrim. When I ate asparagus when I was younger, no probelm. Then I noticed five years ago after eating some asparagus that my urine smelled very pungent. Searching around for answers, it appears to be common for asparagus to do this.

Maybe the Bactrim has added to the experience, but I don't think it's any cause for alarm as long as you are drinking fluids.

I would think you smell it because your kidneys are functioning and detoxing. I'ver had some strange odors like tar or burned rubber (just slight) and think it's my body detoxing ----something?
Posted by Hoosiers51 (Member # 15759) on :
Just to clarify, I was NOT eating asparagus!

And the smell is very distinctive and strong, so that is why it's strange and merits a post.

So I'm thinking it's the Bactrim, and wondering what you guys think?

I wouldn't post to tell you guys I ate asparagus and my pee smells. [Smile]

I don't think it's a problem, just a by-product of the sulfur compounds.

Okay, thanks! I'll still ask my doc next time I talk to him just in case.

Wouldn't it be listed in the warnings for Bactrim if your urine smells like asparagus call your doctor?
