Female contraceptive gel is more effective in contraception when used correctly, but when used incorrectly, it has a high rate of contraceptive failure and also needs to be used under medical supervision. Female contraceptive gel is a chemical contraceptive preparation with sperm inactivation and should be used under medical supervision. It needs to be used before each intercourse, and after placing it in the vagina, you have to wait for 5 to 10 minutes for the drug to dissolve and take effect before having intercourse. It is highly effective when used correctly, but has a high failure rate when used incorrectly, so it is not recommended as the contraceptive of choice. Adverse reactions such as itching and vaginal dysbiosis may also occur with the use of female contraceptive gel, and it is contraindicated for those with a history of allergy. For women of childbearing age who do not wish to have children, they can choose safe and effective contraceptive methods under the guidance of a doctor, such as placing an intrauterine device (IUD), condoms and taking short-acting contraceptives to avoid unwanted pregnancies. If you have any other questions, it is recommended to consult a professional doctor for guidance.
