Hello,
To the question “Does the unremoved expired contraceptive have any effect? ", the doctor would like to answer as follows:
A contraceptive implant is the use of one or more small sticks like matchsticks containing the hormone progesterone implanted under the skin. Once implanted, the implants gradually release hormones into the body creating a contraceptive effect that can last up to 5 years.
When it expires if you do not remove the implant, the effectiveness of contraception will decrease and your chances of unwanted pregnancy are very high. Abdominal pain, insomnia, heat in the body, ... are all accompanying symptoms during the implantation of the implant. These symptoms are usually transient and will subside over time, so there's nothing to worry about.
If you still have questions about the expired contraceptive stick that does not have to be removed, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
