Introduction
If vaginal infection requires a 7–14 day treatment course (e.g., fungal or trichomonal vaginitis), and medication is interrupted after 5 days due to menstruation, treatment should generally be resumed after menstruation ends if symptoms persist (such as itching or abnormal discharge). Incomplete treatment courses may lead to recurrent inflammation; continuing medication helps consolidate therapeutic effects and prevent residual pathogens from causing reinfection.
Menstruation, commonly referred to as "auntie's visit," typically does not interfere with vaginal infection treatment. If menstruation begins on the fifth day of medication for vaginitis, further treatment after the period ends depends on whether the full course of treatment has been completed and whether symptoms have resolved. Generally, if the treatment course is incomplete and symptoms persist, continued medication is usually necessary; however, if the full course has been completed or symptoms have completely disappeared, additional medication is not needed. If in doubt, it is recommended to consult a healthcare provider in advance. Detailed analysis is as follows:
If the treatment for vaginitis requires a 7–14 day course (such as for fungal or trichomonas vaginitis), and medication is interrupted on the fifth day due to menstruation, treatment should generally be continued after the period ends if symptoms persist (e.g., itching, abnormal discharge). Incomplete treatment increases the risk of recurrent inflammation; continuing medication helps consolidate therapeutic effects and prevents residual pathogens from causing reinfection.
If the vaginitis is a mild bacterial type and the recommended 5-day treatment course has already been completed, and symptoms have completely resolved after menstruation with follow-up examination confirming resolution of inflammation, no further medication is required. Overuse of medication may disrupt the natural balance of vaginal flora, increasing the risk of other infections; in such cases, discontinuing medication supports recovery of the vaginal environment.
After interruption of treatment due to menstruation, observe symptom changes after the period ends, and seek medical evaluation if necessary. If continuing medication, adhere strictly to the remaining days of the original treatment plan without adjusting dosage independently. Maintain good local hygiene during treatment, avoid sexual intercourse, and ensure optimal treatment outcomes.
