The short version for both yeast infections and bacterial vaginosis (BV): wait until you've completed the full treatment course and symptoms have genuinely resolved, not just improved. Having sex too early can prolong irritation, reintroduce friction to tissue that's still healing, and in some cases interfere with how well the treatment works.
Yeast infections
General guidance is to wait until the full course of treatment is finished and symptoms — itching, discharge, irritation — have cleared, which is often around a week from starting treatment but genuinely depends on the specific medication and how quickly your body responds. Yeast infections aren't classified as an STI, but sexual activity during an active infection can worsen irritation and, in some cases, pass yeast overgrowth to a partner, particularly relevant for penis-having partners.
Bacterial vaginosis (BV)
Similarly, waiting until the prescribed course is complete and symptoms have resolved is standard guidance. Sex during treatment can disrupt the vaginal bacterial balance treatment is working to restore, and BV is also associated with a temporarily higher susceptibility to other infections while active — another reason full resolution matters before resuming, not just symptom improvement.
What actually helps recovery either way
- Finish the entire prescribed course, even if symptoms improve early — stopping early is a common cause of recurrence.
- Avoid scented products, douching, and anything that disrupts natural pH during and after treatment.
- If symptoms recur frequently, that's worth discussing with a doctor as its own pattern rather than treating each instance in isolation.
