Question: how long does it take for antibiotics to work for trichomoniasis?
Answer: How Long Do They Take to Work? You're typically cured in about 7 to 10 days, but check with your doctor to know for sure. It's not uncommon for people to get another trich infection a few months after treatment. So make sure you don't have sex again until you and your sex partners are cured and your symptoms are gone.
