Anaesthetics
As part of a general anaesthetic, we commonly administer drugs to relax your muscles. Then, before you wake up, we administer drugs to reverse this effect.
You have been given a ‘reversal drug’ today called Sugammadex. Another name for this drug is Bridion. This drug has a unique interaction with the hormone progesterone. This is why you have been provided with this information leaflet.
Sugammadex temporarily increases your likelihood of becoming pregnant after unprotected sexual intercourse in certain situations.
Types of oral hormonal contraceptive you may be using:
The effect of Sugammadex means that even if you took your pill this morning, it is the equivalent to one missed pill.
Advice: You must follow the missed pill advice in the package leaflet of the oral contraceptive.
Types of other hormonal contraceptive you may be using:
Advice: You must use a barrier method of contraceptive e.g condoms for the next seven days.
Types of non-hormonal contraceptive you may be using:
Advice: No further action is required. Sugammadex only reduces the effectiveness of hormone-based contraceptives.
Will other drugs given to me as part of the anaesthetic affect my hormonal contraceptive?
No, this interaction is not known to occur with other anaesthetic-related drugs.
For further contraceptive advice please contact your GP or local sexual health and contraceptive services.
