I Had Unprotected Sex With A Girl That Tested Positive
Metronidazole one single dose of 2grams.
Hello dear, welcome to Ask a doctor's service.
I read your query and here is my advice.
I think it would be better to get tested first.
If you are confirmed that you are having trichomoniasis you may need to take metronidazole one single dose of 2 grams.
It can be taken only with doctor's prescription because it can't be taken over the counter.
Hope I have answered the question.
Let me know if I can assist you further
