SEVOFLURANE BAXTER contains sevoflurane. Sevoflurane is a general anaesthetic used in surgery in adults and children. It is an inhalation anaesthetic given to you as a vapour for you to breathe in. Breathing in sevoflurane vapour causes you to fall into a deep, painless sleep. It also maintains a deep, painless sleep (general anaesthesia) during which you can undergo surgery.
1. What SEVOFLURANE BAXTER is and what it is used for
2. What you need to know before you are given SEVOFLURANE BAXTER
SEVOFLURANE BAXTER should be administered only by health care professionals appropriately trained in the administration of general anaesthesia under the supervision of or by an anaesthetist.
SEVOFLURANE BAXTER should not be administered to you:
- If you are allergic (hypersensitive) to sevoflurane or other inhalation anaesthetics.
- If you have a history of confirmed inflamed liver (hepatitis) due to sevoflurane or other inhalation anaesthetics or you have a history of unexplained liver problems with jaundice, fever, and an increased number of a certain type of white blood cells.
- If you have a known or suspected susceptibility to malignant hyperthermia (a sudden and dangerously high increase in body temperature during or shortly after surgery).
- If you have a neuromuscular disease e.g. Duchenne muscular dystrophy.
- If there are medical reasons why you should not be given a general anaesthetic.
If any of the above applies, please inform your doctor or anaesthetist before you are given this medicine.
Warnings and precautions
Tell your doctor or health care provider before being given SEVOFLURANE BAXTER:
- If you have previously been given an inhalation anaesthetic, particularly if this was more than once and fairly recently (repeated use).
- If you have low blood pressure.
- If you are hypovolemic (reduced blood volume) or are weak.
- If you have impaired kidney function.
- If you are pregnant or breastfeeding or when this medicine is given for obstetrical anaesthesia (delivery of a baby) (see also section entitled “Pregnancy and breastfeeding”).
- If you have a coronary artery disease (narrowed or blocked arteries).
- If you have ever had QT prolongation (prolongation of a specific time interval in an ECG) or torsade de pointes (a specific type of heart rhythm), which may also be associated with QT prolongation, or are at risk of getting these heart conditions.
- If you have a risk of increased pressure within the brain.
- If you have or previously had liver problems, e.g. hepatitis (inflamed liver) or jaundice.
- If you are being treated with a medicine that may cause liver problems.
- If you have had or are at risk of having seizures (fits).
- If you have a disorder of the cells (a condition called mitochondrial disorder).
In the rare and unforeseen instance that you may develop malignant hyperthermia (a sudden and dangerously high increase in body temperature during or shortly after surgery), your doctor (anaesthetist) will stop the administration of SEVOFLURANE BAXTER and will treat the condition, together with the provision of supportive therapy. There have been reports of deaths as a result of malignant hyperthermia, following sevoflurane administration.
Interference with daily activities may continue for up to 24 hours after having been given SEVOFLURANE BAXTER. You should not make any legal or contractual decisions within at least 24 hours after receiving SEVOFLURANE BAXTER. Alcohol should also be avoided for the same time period. You may experience small changes in mood for several days after receiving anaesthesia.
Children and adolescents
In addition to the warnings and precautions above, if SEVOFLURANE BAXTER is to be given to your child, tell their doctor (anaesthetist), nurse or surgeon if they:
- Have Down syndrome (a condition in which the child has an extra chromosome, which may result in growth delays and intellectual disability).
- Have Pompe’s disease (a rare metabolic disorder, which results in the accumulation of glycogen in the body).
If any of the above apply to you or your child, check with your doctor, anaesthetist or health care provider. You or your child may need to be checked carefully and treatment may be changed. After your child has woken up from the anaesthesia they may be agitated, experience involuntary muscle movements or cramping. This should resolve without treatment.
Other medicines and SEVOFLURANE BAXTER
Always tell your health care provider if you are taking any other medicine (this includes complementary or traditional medicines). The medicines or active substances included in the medicines listed below, may influence each other’s effect when used together with SEVOFLURANE BAXTER.

3. How you will be given SEVOFLURANE BAXTER
You will not be expected to give yourself SEVOFLURANE BAXTER. It will be given to you by a person who is qualified to do so. SEVOFLURANE BAXTER will be given to you by an anaesthetist. The anaesthetist will decide on how much you need and when it is to be given. The dose will vary according to your age, weight, the type of surgery you need, and other medicines given to you during surgery.
SEVOFLURANE BAXTER is produced from liquid sevoflurane in a vaporiser, specifically designed for use with sevoflurane. You may be asked to breathe the sevoflurane vapour through a mask to make you fall asleep. You may also be given an injection of another anaesthetic to make you sleep before being given SEVOFLURANE BAXTER through a mask or a tube in your throat.
Your anaesthetist will decide when to stop giving you SEVOFLURANE BAXTER. You will then wake up a few minutes after administration is stopped.
If you are given more SEVOFLURANE BAXTER than you should Since a health care provider will administer SEVOFLURANE BAXTER, he / she will control the dosage. However, in the event of overdosage your doctor or anaesthetist will manage the overdosage.
