Trich Med question

Hello Dr. Two months ago I went to my doctor concerned that I may have an STD of some type. I was feeling a tingling in my penis, no discharge, no sores, nothing--just the tingling sensation in my penis and a little pain in the head of my penis after ejaculation. All tests (chlamydia, gonnorhea, herpes, syphillis, hiv) came back negative, but he told me that I may have Trichmonas, but testing may or may not detect it. He prescribed metronidazole 2-250mg tablets twice daily for 10 days and suggested that my partner get treated as well. The woman that I was seeing didn't get treated because she believed she didn't have anything, because she didn't have any of the symptoms associated with trich. since she refused treatment I refused to have unprotected sex. Well, a couple of weeks later while having protected sex the condom broke and i was stupid enough to continue on without a condom. Very paranoid the next few days I watched for symptoms until I felt a little discomfort. I did another round of metroidazole just to be on the safe side (2-250/dayx10).

After that there were no signs or symptoms to be seen. I felf better mentally until we were having sex again about a week ago and another condom broke ( I know, I'm stupid!!). i had 16 tabs of the metro remaining and read somewhere that 2g would be enough to clear up a trich infection, so 2 days after the 2nd broke condom I took one large 2g dose per day for 2 days. that was 5 days ago. I'm still feeling the tingling in my penis and had hopes that it would have gone away by now. My question is, 1.) Can it be possible that the antibiotics are no longer effective against the trich that I have because I have had it twice before and treated it with the same medication? 2.) Did I take it (the 2g doses) too soon after the exposure and not allow the trich to fully develop and the meds were out of my system when it did develop? Once again, thanks for any help you can provide.

One dose of 2 grams will do it.

i am just wondering what is the correct dose of metronidazole to treat Trichomonas.  My doctor said one dose (2 capsuls) should clear the problem.  Is this correctÉ

You are compulsively over-analyzing the situation, which itself is evidence of the likely emotional aspects of the problem.  See the last line of my last reply.  I have no further comments or advice.

Last questions Dr.

Could the metronidazole not have been effective the third time around, because I had taken it taken so much of it before in such a short period of time (two month span)?

Assuming I was reinfected during my last exposure and took the metronidazole before symptoms started, could I have taken the medication too early before symptoms started for it to have effectively treated the infection

Thanks for your time. I won't post anymore questions.

The repeated infection scenario really doesn't seem plausible.  When trich causes symptoms, usually there is urethral discharge, not tingling, and most women with trich are not asymptomatic; your partner's conviction she has no STD probably is reliable.  Resistance of trich to metronidazole is uncommon and is not know to be triggered by exposure to the drug.

Anyway, what's the big deal?  Trich is harmless in men and eventually goes away on its own.

Drop trich.  It isn't the problem.

Considering I possibly had it and contracted it all three times from my current girlfriend. would or could my body or the trich have built up some sort of defense against the antibiotic? I am worried to death and have definitely given the possibility of genitally focused anxiety some thought, and realize it is a possibility.

My major concern is whether or not the trich ( if I had it) could have possibly turned drug resistant because of the number of times I possibly have contracted it? Or did I take it (the meds) too soon to alleviate it (Trich) the last time I took it and possibly contracted it.

The symptoms you describe are not particularly suggestive of an STD.  It was reasonable to get checked out, but combining the atypical symptoms plus the negative test results makes STD nearly impossible as an explanation.  There is no evidence that trichomonas causes such symptoms; it comes up only because, as in your case, there is no reliable test for it, so treating for that possibility is the only real option.  But in the slim chance you had trich, you have been greatly over-treated for it and you can be sure you don't have it now.

Therefore, something else is causing your symptoms.  The most common cause of such things is genitally focused anxiety.  I am not a believer in anxiety creating symptoms out of the blue.  However, stress, anxiety, and other mental stresses definitely can magnify otherwise normal body sensations to a point that makes them very real.  If your symptoms persist or you remain concern, you might raise this possibility with your provider.  But if you just sit tight, most likely the symptoms will fade with time.  In any case, you can be certain you have nothing sexually transmitted, nothing that will ever harm your health, and nothing you can transmit to a sex partner.

Good luck--- HHH, MD
