Patient's question:
Hello! Since my son is only 5 months old now, he cannot take oral contraceptives. I don't know which contraceptive method would be better. I heard there is something called a "long-acting contraceptive injection," but I'm not sure if it can be used during breastfeeding?First follow-up question: First of all, thank you, Dr. li1106. Because I heard that there could be allergic reactions after inserting an intrauterine device, I didn't dare to do it. Could anyone tell me about the long-acting contraceptive injection?
Second follow-up question: Hello, Fangyu, I didn't expect the long-acting contraceptive injection to be so troublesome. I just wanted to ask you one more thing—does it have any effect on the child?
Doctor's answer:
Hello, the long-acting contraceptive injection, also known as Contraceptive Injection No. 1, provides one month of contraception with a single injection.Usage: In the first month, inject 2 vials. This can be done on the 5th day of the menstrual period by simultaneously injecting 2 vials, or by injecting 1 vial on the 5th day and another on the 10th day. For the second month and beyond, inject 1 vial within the 10–12 days of the menstrual period. The long-acting injection should be administered as a deep intramuscular injection. In rare cases, some individuals may experience an allergic reaction. After injection, wait for 15 minutes before leaving.
During the course of treatment, if the menstrual period is prolonged, you may take Contraceptive Tablets No. 1 or No. 2, 1–2 tablets daily, for 4 consecutive days. If the menstrual period is shortened, start taking Contraceptive Tablets No. 1 or No. 2 10 days after injection, 1–2 tablets daily, for 4–6 consecutive days. For individuals with amenorrhea, inject another dose 28 days after the last injection. If amenorrhea persists for 2 consecutive months, stop the injections.
If you have been using the long-acting contraceptive injection for an extended period, continue taking Contraceptive Tablets No. 1 or No. 2 for 3 consecutive cycles after discontinuing use to avoid menstrual irregularities.
