Patient's question:
Can you use contraceptive film and contraceptive suppositories at the same time? Will the effect be enhanced when used together?Why do I feel a stinging sensation in my vagina after using contraceptive suppositories? It also hurts a little when I urinate. Could it cause vaginitis or other infections?
Doctor's answer:
1: Condoms are a type of external contraceptive. Currently, most commonly used condoms are made primarily of nonoxynol-9 as the active ingredient and polyvinyl alcohol as the water-soluble film-forming material. Nonoxynol-9 has the characteristics of rapid and highly effective spermicidal action. Five minutes before sexual intercourse, the film is rolled into a ball and placed deep into the vagina. After nonoxynol-9 dissolves in the vagina, it interacts with the lipid membrane of sperm cells, altering the permeability of sperm cells, killing sperm or rendering them inactive, making it difficult for sperm to pass through the cervix to complete fertilization, thereby achieving the purpose of contraception.2: Contraceptive suppositories are a type of external contraceptive, with benzyl acetate mercury as the main ingredient, and additional oily excipients. The former can kill sperm, while the latter melts into an oily state, which can hinder sperm movement and prevent sperm from entering the cervix, thereby achieving the purpose of contraception. This method of contraception, if used correctly, on time, and in the right amount, is very effective and has no side effects.
