I am taking Bactrim (antibiotic) for a urinary tract infection.I took the first pill last night at around 9.30 pm. About an hour ago, I took half a trazodone. Can this cause an interaction? I am due to take my next bactrim in about an hour. Is this safe? I am kinda scared.

I am also on levora birth control and taking probiotics to prevent a yeast infection.

thanks for any help
