Other Medicines and Sugammadex Synthon

Tell your anesthesiologist if you are taking, have recently taken, or may need to take any other medicine.

Some Medicines Reduce the Effect of Sugammadex Synthon

It is especially important to inform your anesthesiologist if you have recently taken:

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

This Medicine May Affect Hormonal Contraceptives

This medicine may make hormonal contraceptives - such as the "Pill", vaginal ring, implants, or an Intrauterine Hormonal Device (IUD-h) - less effective because it reduces the amount of progestogen that reaches you. The amount of progestogen lost due to the use of this medicine is approximately the same as when you miss a contraceptive pill.

• If you are taking the Pillon the same day that you are given this medicine, follow the instructions for missing a pill in the pill's package leaflet.
• If you are using otherhormonal contraceptives (e.g., vaginal ring, implant, or IUD-h), you should use a non-hormonal contraceptive method (such as a condom) for the next 7 days and follow the recommendations in the package leaflet.

Effects on Blood Tests

In general, this medicine does not affect laboratory tests. However, it may affect the results of a blood test when progesterone levels are measured. Consult your doctor if your progesterone levels need to be analyzed on the same day you receive this medicine.

Pregnancy and Breastfeeding

Tell your anesthesiologist if you are pregnant or think you may be pregnant or if you are breastfeeding.

It may still be given to you, but this needs to be discussed beforehand.

It is not known if sugammadex can pass into breast milk. Your anesthesiologist will help you decide whether to interrupt breastfeeding or avoid treatment with sugammadex, considering the benefit of breastfeeding for the baby and the benefit of this medicine for the mother.

Driving and Using Machines

This medicine has no known influence on the ability to drive and use machines.

Sugammadex Synthon Contains Sodium

This medicine contains up to 9.7 mg of sodium (a major component of cooking/table salt) per mL.

Dose less than or equal to 2.4 ml

A dose of 2.4 ml (or less) contains less than 1 mmol of sodium (23 mg), which is essentially "sodium-free".

Dose greater than 2.4 ml

A dose of 2.4 ml (or more) contains 1 mmol (or more) of sodium (23 mg). This is equivalent to 1.15% (or more) of the maximum recommended daily sodium intake for an adult.

Tell your anesthesiologist if you are on a controlled salt diet.

3. How to Use Sugammadex Synthon

This medicine will be given to you by your anesthesiologist or under their supervision.

Dose

Your anesthesiologist will calculate the dose of this medicine you need based on:

• your weight
• the amount of muscle relaxant that is still affecting you.

The usual dose is 2-4 mg per kg of body weight for adults and for children and adolescents between 2-17 years. A dose of 16 mg/kg may be used in adults if urgent recovery of muscle relaxation is needed.

How Sugammadex Synthon is Administered

This medicine will be administered by your anesthesiologist. It is injected once into a vein.

If You Are Given Too Much Sugammadex Synthon

Since your anesthesiologist will be carefully monitoring the situation, it is unlikely that you will be given too much of this medicine. But even if this happens, it is unlikely to cause any problems.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medicine and the amount ingested.

If you have any further questions about the use of this medicine, ask your anesthesiologist or another doctor.

If these side effects occur while you are under anesthesia, your anesthesiologist will detect and treat them.
