Is vaginal douching necessary after using promestriene vaginal capsules?

Under normal circumstances, vaginal douching is not required after using progesterone vaginal capsules. Blind douching may instead affect the drug's effectiveness, as the medication needs to continuously act within the vagina to achieve therapeutic effects. Detailed explanations are as follows:

Progesterone vaginal capsules are a locally-acting medication absorbed through the vaginal mucosa, used to relieve vaginal discomfort caused by estrogen deficiency. After insertion into the vagina, the active ingredient is gradually released and absorbed, while residual medication debris is naturally expelled along with vaginal secretions—there is no need for deliberate douching. Douching can directly remove unabsorbed medication from the vagina, shorten the duration of drug action, and reduce treatment efficacy.

Some individuals may experience a sensation of foreign body in the vagina after using the medication; however, if there is no obvious discomfort such as itching or abnormal odor, no special intervention is needed. It is important during treatment to maintain external genital hygiene—washing the external genital area daily with warm water is acceptable, but avoid douching the vaginal canal to prevent disruption of the natural vaginal flora balance and reduce the risk of infection.

In daily life, change cotton underwear frequently and keep the external genital area dry and well-ventilated. Avoid sexual intercourse during treatment to prevent interference with drug absorption or increased irritation of the vaginal mucosa. If symptoms such as abnormally increased discharge occur, monitor changes in symptoms but do not attempt self-treatment through douching.
