Women undergoing NHS operations are not being routinely informed that a drug commonly used in anaesthesia may make their contraception less effective, putting them at risk of an unplanned pregnancy, doctors have warned.
Administered at the end of surgery before patients wake up, sugammadex reverses the action of drugs that are given earlier in the procedure to relax the patient’s muscles. The drug is known to interact with the hormone progesterone and may reduce the effectiveness of hormonal contraceptives, including the progesterone-only pill, combined pill, vaginal rings, implants and intra-uterine devices.
