1. What Sugammadex is and what it is used for

What Sugammadex is

Sugammadex contains the active substance sugammadex.

Sugammadex is considered to be a Selective Relaxant Binding

Agent since it only works with speciic muscle relaxants,

rocuronium bromide or vecuronium bromide.

What Sugammadex is used for

When you have some types of operations, your muscles must be

completely relaxed. This makes it easier for the surgeon to do the

operation. For this, the general anaesthetic you are given includes

medicines to make your muscles relax. These are called muscle

relaxants, and examples include rocuronium bromide and

vecuronium bromide. Because these medicines also make your

breathing muscles relax, you need help to breathe (artiicial

ventilation) during and after your operation until you can breathe

on your own again.

Sugammadex is used to speed up the recovery of your muscles

after an operation to allow you to breathe on your own again

earlier. It does this by combining with the rocuronium bromide or

vecuronium bromide in your body.

It can be used in adults whenever rocuronium bromide or

vecuronium bromide is used and in children and adolescents (aged

2 to 17 years) when rocuronium bromide is used for a moderate

level of relaxation.

2. What you need to know before Sugammadex is given

You should not be given Sugammadex

  • if you are allergic to sugammadex or any of the other ingredients

    of this medicine (listed in section 6).

Tell your anaesthetist if this applies to you.

Warnings and precautions

Talk to your anaesthesist before Sugammadex is given:

  • if you have kidney disease or had in the past. This is important as

    sugammadex is removed from your body by the kidneys.

  • if you have liver disease or have had it in the past.
  • if you have luid retention (oedema).
  • if you have diseases which are known to give an increased risk

    of bleeding (disturbances of blood clotting) or anticoagulation

    medication.

    Children and adolescents

    This medicine is not recommended for infants less than 2 years of age.

    Other medicines and Sugammadex

    Tell your anaesthetist if you are taking, have recently taken or might take any other medicines.

    Sugammadex may affect other medicines or be affected by them. Some medicines reduce the effect of Sugammadex

    It is especially important that you tell your anaesthetist if you have recently taken:

    • toremifene (used to treat breast cancer).
    • fusidic acid (an antibiotic).

Sugammadex can affect hormonal contraceptives

Sugammadex can make hormonal contraceptives - including the ‘Pill’, vaginal ring, implants or a hormonal Intra Uterine System (IUS) - less effective because it reduces how much you get of the progestogen hormone. The amount of progestogen lost by using Sugammadex is about the same as missing one oral contraceptive Pill.

  • If you are taking the Pill on the same day as Sugammadex is given to you, follow the instructions for a missed dose in the Pill’s package lealet.
  • If you are using other hormonal contraceptives (for example a vaginal ring, implant or IUS) you should use an additional non-hormonal contraceptive method (such as a condom) for the next 7 days and follow the advice in the package lealet. Effects on blood tests

In general, Sugammadex does not have an effect on laboratory tests. However, it may affect the results of a blood test for a hormone called progesterone. Talk to your doctor if your progesterone levels need to be tested on the same day you receive Sugammadex.

Pregnancy and breast-feeding

Tell your anaesthetist if you are pregnant or might be pregnant or if you are breast-feeding.

You may still be given Sugammadex, but you need to discuss it irst.

It is not known whether sugammadex can pass into breast milk. Your anaesthetist will help you decide whether to stop breast-feeding, or whether to abstain from sugammadex therapy, considering the beneit of breast-feeding to the baby and the beneit of Sugammadex to the mother.

Driving and using machines

Sugammadex has no known inluence on your ability to drive and use machines.
